Railroad Maintenance and Operations Handbook For Local Governments and Rail Carriers 2nd Edition North Central Texas Council of Governments 
What is NCTCOG? The North Central Texas Council of Governments is a voluntary association of cities, counties, school districts, and special districts which was established in January
1966, to asslsllocal govemments in planning for common needs, cooperating for mutual benefit, and coordinating for sound regional developmenl. It serves a 16-county metropolitan region
centered around the two urban centers of Dallas and Fort Worth. Currently the Council has 220 members, including 16 counties, 157 cities, 25 independent school districts and 22 special
districts. The area of the region is approximately 12,800 square miles, which is larger than nine states, and the population of the region is over 4.2 million, which is larger than 30
states. NCTCOG's structure is relatively simple; each member government appoints a voting representative from the governing body. These voting representatives make up the General Assembly
which annually elects an II-member Executive Board (9 local elected officials and 2 regional citizens). The Executive Board is supported by policy development, technical advisory, and
study committees, as well as a professional slaff of approximately 100. NCTCOG's offices are located in Arlington in the Centerpoint Two Building at 616 Six Flags Drive (approximately
one-half mile south of the main entrance to Six Flags Over Texas). North Central Texas Council of Governments P. O. Box 5888 Arlington, Texas 76005-5888 (817) 64()"3300 NCTCOG's Department
of Transportation Since 1974 NCTCOG has served as the Metropolitan Planning Organization (MPOl for transportation for the Dallas-Fort Worth area. NCTCOG's Department of Transportation
is responsible for the regional planning process for all modes of transportation. The department provides technical support and staff assistance to the Regional Transportation Council
and its technical committees, which compose the MPO policy-making structure. In addition the department provides technicel aSSistance to the local governments of North Central Texas
in planning, planning, coordinating, and implementing transportation decisions. Prepared in cooperation with the Texas Department of Transportation and the U. S. Department of Transportation,

I. INTRODUCTION Railroad maintenance and operation procedures vary widely in the North Central Texas Region. In response to a request from local communities and railroad operators, this
report was prepared to recommend guidelines which are agreeable to several interested parties including; local govemments, the Railroad Commission of Texas (RCn, the Texas Department
of Transportation (TxDOn, the Federal Railroad Administration (FRA) , and major passenger and freight rail operators within the region. These recommendations are not enforceable by legislative
action unless expressly stated in the report. Jurisdictional issues, either as separate or jOint responsibilities among local, state, or federal agencies and affected' railroad companies,
are presented with uniform guidelines and recommendations to be considered by the 16-county North Central Texas Region as shown in Figure 1-1. The specific railroad network within the
North Central Texas Council of Governments (NCTCOG) Transportation Study Area is shown in Figure 1-2. Section II of this report provides a summary and recommendations for selected maintenance
issues. Grade crossing upgrades using the TxDOT Priority Index (PI) and a survey of funding mechanisms are discussed. The TxDOT Railroad Grade Crossing Replanking Program is presented
which describes how the state reviews crossing projects located on the State Highway System. The Highway-Rail Crossing Surface Ranking Index presents a subjective evaluation process
for rating crossing conditions. Jurisdictions of responsible agencies are considered along with maintenance of track, signals, pavement, drainage, signs, pavement markings, fencing,
selection of grade crOSSing materials, reflectorized tape on signs, crossing illumination, track inspections, visual obstructions at crossings, and temporary grade crossing closures
for maintenance.

Section III provides a summary of existing railroad and highway operational issues with recommendations for speed restrictions, size restrictions, blocked grade crossings, railroad noise
related to existing land uses, motorist education, legal responsibilities of motorist, and police enforcement as well as contact numbers for city officials and rail carriers. All references
regarding cost estimates are expressed in 1989 dollars using the consumer price index. "Railroad operators" in this report refer to freight, passenger, and heavy rail commuter trains.
"Active warning devices" refer to crossings with gates or flashers to warn of an approaching train. "Passive warning devices" refer to crOSSings with a crossbuck warning assembly. This
handbook is being prepared as the second phase of a NCTCOG Railroad Coordination Study. Phase One of this project addressed a railroad and roadway grade separation needs assessment benefit-cost
analysis. Hazardous material transportation in railroad corridors will form the basis of a future study. REGULATION AUTHORITY JURISDICTIONS Nine agencies have jurisdiction over railroad
operations and maintenance activities. These agencies' responsibilities overlap depending on the context of the situation. A selective list of agencies and their responsibilities of
interest to local cities and railroad operating offiCials in the NCTCOG region is as follows: Environmental Protection Agency (EPA) -Develops standards and procedures for environmental
impact statements and assessments; develops noise policies for constant and repetitive noise sources and their effects on adjacent land uses and identifies future goals for 1-4 
noise reduction nationwide relative to public health and welfare; and developed Railroad Noise Emission Standards for rail carriers engaged in interstate commerce with compliance responsibility
resting with the ERA. Federal Railroad Administration (FRA) -Enforces the Code of Federal Regulations (CER); enforces noise standards by testing moving, stationary, and switcher trains;
specifies track classes including a reference to maximum railroad operating speeds; investigates complaints by the public regarding crossings; investigates selected train/vehicle crossing
accidents usually where two or more fatalities occur; maintains the accidenllincident reporting system; and is custodian of the U.S. Department of Transportation (DOn American Association
of Railroads (MR) National RaiVHighway Crossing InVentory. Federal Highway Administration (FHWA) -Administers federal funding for crossing safety improvements (railroad crossing upgrades)
through the Surface Transportation Program (STP) under the Intennodal Surface Transportation Efficiency Act of 1991 (ISTEA) for all systems of roads and highways; publishes signs and
pavement marking standards in the Manyal on Uniform Traffic Control Devices (MUTCD); and conducts crossing research in coordination with the ERA. Interstate Commerce Commission (ICC)
-Generally deals with cost-effective and competitive rail transportation issues on an interstate level; has jurisdiction over the supply of railroad equipment; and requires environmental
assessments of increased rail traffic of approximately 50 percent or greater or eight trains/day derived from mergers and new line construction which cause extra rail traffic. 1-5 
National Highway Traffic Safety Administration (NHTSA) -Maintains the Fatal Accident Reporting System (FARS). Department of Public Safety (DPS) -Enforces railroad-highway crossing safety
laws and maintains railroad/highway accident data which is forwarded to the Texas Department of Transportation (TxDOT) and NHTSA; receives and passes to railroads reports of crossing
signal problems made by the public using a toll-free 1-800 telephone number. Railroad Commission of Texas (RCT) -Assists the FRA with the inspection of railroad equipment, operations
and track; enforces state legislation regarding sight rectangle and clearance on bridges; has the authOrity to close crossings; and investigates complaints by the public regarding crossings.
Texas Department of Transportation (TxDOT) -Develops an annual list of recommended railroad-highway crossings for FHWA crossing safety improvement funds, administers the projects, and
coordinates the on-site joint inspection of crossings for potential upgrading which includes a a team of rail operators, cities, counties, school districts, and law enforcement officials
to recommend the type of safety improvements. City Law Enforcement -Enforces traffic and trespass laws; completes railroad/accident reports; and issues citations for railroad ordinance
infractions if warranted. Operation Lifesaver -Public information and education program thatpromotes crossing and trespasser safety programs to help prevent and reduce crashes, injuries, and fatalities and improve driver performance at public and private highway-rail grade
crossings. Operation 1-6 
Lifesaver involves the railroads. related federal. state. and local governments. business. railroad suppliers. labor, and other concerned safety professionals. Provides contact for Operation

II. MAINTENANCE The purpose of this chapter is to present the findings and recommendations of the Railroad Maintenance Work Group to the Railroad Coordination Task Force for consideration
as a regional maintenance handbook for rail corridors in the Dallas-Fort Worth area. The Railroad Maintenance Work Group was formed in early 1989 with members from local cities, rail
carriers, the Federal Railroad Administration (FRA), the Railroad Commission of Texas, and the Texas Department of Transportation (TxDOl). Their expertise plus current case law and civil
statutes were utilized to develop this rail corridor maintenance and operations handbook. The major issues of mutual interest addressed in this section are: the TxDOT Grade Crossing
Priority Index (PI) and funding for crOSSing improvements, the TxDOT Railroad Grade Crossing Replanking Program, the Rorida Highway Rail Crossing Surface Ranking Index, and a SUbsection
on the jurisdictions of responsible agenCies. The jurisdictions briefly discuss basic grade crossing elements which include: track maintenance, signal maintenance and traffic signal
preemption, pavement alignment, drainage, advance signs and pavement markings, fencing, grade crossing materials, reflectorized tape on signs, illumination of crossings, track inspections,
visual obstructions including vegetation control, temporary crOSSing closures, and the existing toll-free number in Texas for reporting grade crOSSing signal problems. All handbook sections
which quote costs are expressed in 1989 dollars. If costs were ciled from references expressed in previous year dollars, the figures were adjusted using the consumer price index. 
TEXAS PRIORITY INDEX FOR RAILROAD-HIGHWAY GRADE CROSSINGS In Texas, federal funds have been available for crossing upgrades since the 1930s. The Federal Highway Administration (FHWA)
and TxDOT manage the railroad-highway crossing safety improvement program under a federal oversight agreement to provide federal funds to Texas for highway-rail grade crossing safety
improvements. This program, formerly funded under the Section 130 Rail-Highway Crossings program, is funded from part of the 10 percent of Surface Transportation Program (STP) funds
set aside for safety. These funds have been apportioned by the ratio of the number of public crossings in the state to the total number of public crossings in the country as well as
the state's population, area, and road mileage. FHWA provides 90 percent of the funding on all roadway systems for crOSSing improvements, with the state providing a 10 percent contribution.
The Texas Transportation Commission annually approves funding of the state matching funds for the Rail-Rail-Highway Crossings program. The local govemments' contribution is to provide
any roadway approach or alignment improvements, utility or drainage adjustments, and vegetation trimming or removal. Federal funds are primarily used to upgrade passively signed crossings
to active waming signals. Other eligible safety improvements include advance waming signs, removal of visual obstructions, grade separation/bridge construction, improve roadway approaches,
illumination. pavement markings, pavement rehabilitation, crossing surface material installation, signal preemption, drainage, and crossing closures or consolidations. Crossings located
on the State Highway System are also eligible for other state funds for crossing surface improvements. Additional information on the TxDOT Replanking Program is provided in the next
section. TxDOT uses a selection process that prioritizes the Federal funded crossing safety projects by a priority index. The Texas Priority Index process is outlined in Figure 11-1.

allocated to the top ranked projects until the available funds are expended, The top ranked projects in each TxDOT district are then evaluated on site by a team of professionals with
railroad and highway expertise. This diagnostic team is comprised of rail carriers, TxDOT officials, and local govemment officials, The diagnostic team considers the local conditions
and alternatives and is then responsible for recommending the type of waming devices and other safety enhancements as required, First consideration is given to the necessity of the crossing
in relation to adjacement crossings. Local authorities are encouraged to attend these evaluations. Their knowledge is especially helpful in presenting such significant factors on local
conditions as a site's proximity to schools, hospitals, businesses, or residences, traffic pattems, type of vehicles using crossings, special conditions. etc. With the number of participants
involved, instaliation typically occurs 18 months from initiation of the project. The crossing safety improvement program does not preclude the FHWA, TxDOT, municipalities, and railroads
from joining in railroad crossing projects outside the "window" of funding priorities if they so choose. Local governments should negotiate with the rail carriers to upgrade the crossing
surface with higher quality, more durable materials such as rubber or concrete panels. Typical average costs for improvements are shown in Figure 11-2. TxDOT uses the most current data
available to update their traffic counts and accident records; this insures that the projects receive an accurate priority ranking. Local authorities may forward their most recent average
daily traffic (ADT) counts to TxDOT District Offices. or request that the TxDOT District Office perform a traffic count, to be included in the priority index formula. TxDOT analyzes
a five-year period of accident statistics when determining accident trends at highway-rail grade crossings to quantify the hazard potential, 11-4

With over 13,000 public grade crossings in Texas and funds for approximately 200 projects per year; TxDOT developed the project selection procedure using a priority index (PI) formula.
The Texas Grade Crossing Priority Index Program funded 227 projects in 1994 for $20 million and is estimated to fund 160 projects in 1995 for $15 million and 250 projects in 1996 for
$25.9 million. The Texas PI uses a variation of the New Hampshire Index to prioritize grade crossings for potential upgrading. The potential for railroad-highway grade crossing accidents
is primarily a function of the number and speed of trains traveling through the crOSSing, the volume of average daily traffic (ADT) utilizing the street facility, the existing traffic
control device(s) in place, and the past five-year train involved accident history. The TxDOT Priority Index as of 1994 is as follows: Texas Priority Index (PI) = V' T' SI • PI' (.01)
• A 1.15 where: V = average daily traffic (vehicleslday) T =number of trains per day SI =speed oftrains (mph· 0.1) PI =protection factor of existing waming devices • gates =0.10 • cantilever
flashers =0.15 • mast flashers =0.70 • cross bucks, wigwags, or bells =1.00 A = number of trainlvehicle accidents in previous five years to the 1.15 power (if A=O or A=1 the default
is 1) An example is provided using the following information where: V = 5,000 vehicles per day, T =10 trains per day, St =30 mph' 0.10 =3.0, Pr =0.70 (existing mast flashers), and A
=0 accidents, 11-6 
the following priority index will result: 15PI = V * T * SI * PI' (.01)' A1. = 5,000 * (10)' (3)' (0.70) * (.01) * (1) = 1,050 Given that the Texas PI cut off for project selection was
317 in 1987, 337 in 1988, and 269 in 1989, this example railroad-highway grade crossing would have ranked above the past minimum priority index thresholds for review and possible upgrade.
Several states employ other variations of the index by adding variables to augment the original equation. Optional safety factors added to this original equation by other states include:
highway speed, crossing width, type of track, local population, volume of transit buses, number of school buses, number of tracks, croSSing surface condition, proximity of nearby intersections,
functional class of the road, vertical alignment, horizontal alignment (crossing angle), volume of trucks carrying hazardous material, average number of vehicle occupants. TxDOT uses
this factor. The Texas Transportation Institute (TTl), under a TxDOT contract, is working on a project to research, evaluate, and recommend revisions to the current Texas Priority Index
for railroadhighway grade crossings. The 1994 TTl report is under review and evaluation by TxDOT to receive final acceptance. A list of some of the more Significant potential factors
that affect grade crossing safety is shown in Figure 11-3. The revised formula may incorporate into the current list of factors the addition of sight distance modifications, approach
factors, reaction factors, vertical alignment, number of school buses, transit buses, hazardous materials carriers, and other "special" vehicles. 11-1

TXDOT RAILROAD GRADE CROSSING REPLANKING PROGRAM The Railroad Grade Crossing Replanking Program has been established between the Texas Department of Transportation and the individual
railroads to maintain grade crossings located on the state maintained highways. This system of review, developed through research conducted by the TIl, provides a uniform basis for identifying
the current crossing conditions of all grade crossings on the State Highway System. Local agencies may find this a useful tool to apply to grade crossings under their jurisdiction to
rank grade crossings for possible surface improvements. This methodology provides an assessment of a highway-rail crossings, but requires professional expertise and judgment in completing
a subjective analysis of the site conditions. The TxDOT District Railroad Project Coordinators perform a visual inspection of all grade crossings located on the State Highway System
in their districts. The visual rating of the crossing considers the condition of the highway pavement, highway traffic volume, train traffic volume, railroad track condition and drainage
factors. The railroad project coordinator assigns a numerical rating between 0 and 5 for the highway, rail, and drainage aspects of the crossing. The results of the highway-rail crossing
inspections are submitted on the Railroad Grade Crossing Submission Forms for all candidate crossing projects to the TxDOT Traffic Operations Division, Railroad Section for review and
prioritization. Figure 11-4 shows the Railroad Grade CrOSSing Submission form. All candidate crossings are prioritized based on an estimated cost per vehicle to repair or replace the
crossing surface. The estimated cost is determined by multiplying the estimated or negotiated cost per track foot by the total track feet proposed for replan king. The average negotiated
cost per track foot for asphalt, concrete panel, and rubber crossing materials are 11-9

below: Estimated Cost per Vehicle 􀁾􀀠(Estimated Cost I Average Daily Traffic) Estimated Cost = (Negotiated Cost per Track Foot) X Total Track Feet Grade crossings with the lowest estimated
cost per vehicle are given the highest priority ranking. The Replanking Program allocates the funds to the highest ranked crossings until the annual, funded apportionment representing
approximately $3.5 million is obligated. This annual apportionment typically funds 140 crossing replanking projects .. Grade crossings on roadways that are not maintained by the state
are not eligible to receive funds through the Replanking Program. HIGHWAY·RAIL CROSSING SURFACE RANKING INDEX At present, no universally accepted procedure exists for cities to objectively
evaluate the current condition of their highway-rail crossing surfaces. The predominant predominant method used to subjectively determine the condition of the crossing surface is by
physical inspection and by riding over it. Crossings that are rough and in need of repair should be called to the attention of the railroad company. Since responsibility for the grade
crossing is shared, both the local agencies and the railroads should be involved in the evaluation of the crossing surface and approaches. Site evaluations and other information such
as safety needs and public complaint are important inputs used to assist in the decision-making process. 11-11 
The Federal Highway Administration Railroad-Highway Grade Crossing Handbook makes reference to a procedure for ranking highway-rail intersections for crossing surface improvement. The
procedure involves evaluating the crossing surface based on actually driving over the crossing and observing other drivers and vehicles as they traverse the crossing. The procedure,
developed by the Florida Department of Transportation (FOOT), Office of Value Engineering, subjectively determines a crossing's rideability and observed condition in deciding whether
the highway-rail crossing needs to be repaired or replaced. The FOOT ranking index takes into account six basic elements: approaches, vehicle reaction, driver reaction, rail/pad condition,
ADT, and percent trucks. The crossing surface index depends on professional judgment to subjectively determine the relative condition for the approaches, vehicle reaction, driver reaction,
and rail/pad condition. These four elements are assigned a number of possible points, within a 100 point system, relative to their overall importance. Figure 11-5 shows the characteristics,
conditions, pOints, and weights in this index. The condition of the characteristics weigh the possible points based on the severity of the judged condition of the element. The weighted
points are summed for each croSSing characteristic to obtain a total adjusted weight (T w) for the surface condition. An example of a crossing evaluated as having severe cracking in
the approach and leave areas, showing appreciable vehicle bouncing, with most drivers slowing and the rails having extensive movement with poor pad condition is rated below. Characteristic

FIGURE 11-5 GRADE CROSSING SURFACE CHARACTERISTICS AND WEIGHTS FIGURE 11-6 ADT/PERCENT TRUCK QUOTIENT (Q) 11-13 
Since the surface condition is directly related to the average daily traffic (ADn and percentage of trucks, a quotient is used to further refine the total adjusted weight (Tw). A quotient,
as shown in Figure 11-6, is applied to the total adjusted weight (T w). If the example crOSSing is in a rural area, where the ADT is almost always less than 5,000, but the percent of
trucks is 15 percent or greater, the value, .93 Q, from Figure /1-6 would be applied to the total adjusted weight (Tw). TwO =crossing rate times the ADTfTruck Quotient The crossing rate
example would result in 38 X .93 = 35.3 The crossing rate is then compared with the grade chart shown in Figure 11-7. The example crossing, which ranks well below the failure rating,
would warrant total replacement. Depending on available funding, the responsible railroad maintenance engineer along with the TxDOT railroad coordinator must decide whether to repair
or replace. Figure 11-8 is an adapted version of the surface ranking form used by FOOT. It should be noted that category points, assigned weights and ADTrrruck Quotients are arbitrary,
but they can be used to establish a prioritized list of crossings which need repair or replacement. FIGURE 11-7 GRADE CROSSING SURFACE RATINGS 1 i GRADE Excellent Good POINTS 90-100

JURISDICTIONS OF RESPONSIBLE AGENCIES Track. Signal. and Crossing Surface Maintenance Within the State of Texas, cities, counties, TxDOT, and railroad operators assume both separate
and joint maintenance responsibilities. Items such as the track and signals are always maintained by the rail operator. However, state civil statutes, site characteristics, and potential
FHWA funding for crossing upgrades are further considerations in determining jointly funded improvements. In Texas, the concept of railroad crossing maintenance occurs as one of the
"enumerated powers" of home rule cities, according to Vernon's Annotated Texas Civil Statutes, Article 1175, Section 16. It requires that railroads be responsible for street improvements
"between the rails and tracks of any such railway companies and for two feet on each side thereof." If the definition of "track," according to the FHWA publication entitled Railroad-Highway
Grade 􀁃􀁲􀁯􀁳􀁳􀁩􀁮􀁾􀀠Handbook, includes: "an assembly of rails, ties, and fastenings over which cars, locomotives, and trains are moved," then the railroad company's maintenance responsibility
extends two feet beyond the ends of ties as shown in Rgures 11-9 and 11-10. However, for practical purposes, the Railroad Maintenance Task Group concurs with the FHWA suggestion in the
Railroad-Highway Grade Crossing Handbook;, "the public agency having responsibility for the maintenance of roadway approaches generally terminates its maintenance responsibility for
the roadway at the crossing surface." The Work Group makes the recommendation that local governments maintain pavement up to the croSSing material located at the end of the ties. However,
according to FHWA, the railroad operator shall maintain any vehicular, pedestrian, or bicycle crossings between the ends of the ties. All of these crossings shOUld be physically separated
for optimal traffic safety reasons. 11-16

Therefore, the railroad is responsible for the maintenance of the rails, ties, fastenings, ballast, initial upper ballast drainage pipe installation, crossbuck sign assembly, railroad
signals, control boxes, and grade crossing surface materials which extend to the ends of the ties. In most cases, the local govemment will be responsible to reimburse the railroad for
the cost differential for any crossing surface desired beyond the standard timber/asphalt surface. Railroad Signal Maintenance and Traffic Signal Preemption Signal maintenance at the
crossing is the responsibility of the railroad carrier. However, TxDOT assists the railroad carrier by reimbursing the railroad a unit price for signal maintenance by the type of signal
on state and federal highway systems, but not on city streets, county roads, or private crossings. If a state or local public agency anticipates future signal preemption of traffic signals
to clear the intersection at a grade crossing before a train approaches, the Railroad Maintenance Work Group recommends that the city should notify the railroad of the intent to use
a circuit in the railroad signal control box. Automatic time crossing devices should be calibrated to the fastest train using the track. When train speed increases are planned, timing
devices should be recalibrated to allow motorists adequate time to clear the crossing prior to the implementation of the new speeds. At the time of installation, the critical cycle time
to clear the intersection of vehicles should be supplied. However, if the critical cycle time exceeds 30 seconds, then a constant warning time device in the railroad control box is necessary
and may be eligible for Rail-Highway Crossings program funding. As an example of cost, an upgrade to a control ·box in 1988 cost TxDOT $2,000, but the conversion of older signal controls
on a direct current system could cost well over $100,000, especially in rural areas. 11-19 
Pavement Alignment Large grade changes in rail elevations would be a situation where the city may not be totally responsible for street approach grade changes. A schedule of cost sharing
between the rail carner and the local government or state agency responsible for the roadway is recommended by the Work Group. The vertical slope of pavement approaching the crossing
is recommended at a range of between 1 and 2 percent for 30 feet beyond the ends of ties, according to the American Railroad Engineering Association (AREA). Pavement sloping away from
the track will also deter the necessity for installation of french drains by the local or state agency to deflect storm water away from the ballast to a storm water system or railroad
ditch. Access to the railroad ditch would be through previous agreement with the railroad. The low vertical pavement slope would also assist faster acceleration of vehicles from a stop
position across the tracks. It would prevent trucks or trailers with low undercarnages from becoming trapped on a severely humped pavement. Horizontal alignment of the approach lanes
is recommended to be as direct to the tracks as possible to assist motorists in viewing any approaching trains without contending with a potential "blind spot" situation. The width of
the crossing surface should be sufficient to include all highway travel lanes and adjacent shoulders plus two feet, with the continuation of all traffic lanes across the tracks. Crossings
that are inadequate in width should be called to the attention of the railroad company. Drainage Proper preparation of the track structure and good drainage of the subgrade are essential
to good performance from any type of crossing surface. Excessive moisture in the soil can cause track 11-20 
settlement, accompanied by penetration of mud into the ballast section. Surface and subsurface drainage should be intercepted and discharged away from the crossing. Ideally. the roadway-railroad
crossing should occur at a rise in topography to ensure drainage away from the ballast to prevent fouling of the ballast with "fines" from the subgrade. Accumulated ''fines'' would cause
the ballast and track to "pump" from railroad loads, cause track instability. and increase the likelihood of a train derailment However, if the pavement slopes toward the crossing the
railroad will install a french drain, and the drain will remain its responsibility as being within the confines of the track. Drainage is a maintenance consideration involving varying
jurisdictions. Drainage structures and ballast are initially installed by railroads on their right-of-way. Bar ditches (or drainage ditches and culverts) are a joint responsibility which
should have negotiated maintenance and improvementsshared by parties benefrting from from the infrastructure or whoever modifies the runoff pattem necessitating improvements. Approach pavement costs can be reduced within the local govemment
right-of-way if the local govemment completes the subgrade preparation with four-inch perforated pipe and filter cloth, according to TxDOT. Use of a suitable filter fabric over the entire
subgrade area under the crOSSing and for a sufficient distance beyond can be a significant aid in separation, filtration, water transport, and tensile reinforcement. It is recommended
by the Work Group that any future drainage problems be the continued legal responsibility of the rail carrier for repairs. Advance Signs and Pavement Markings Standards for advance signs
and pavement markings are found in the Texas Manyal on Uniform Traffic Control Devices (MUTCD). The local agency, as previously recommended by the Work Group, should be the agency responsible
for pavement extending to the crossing material at the 11-21 
edge of the ties, traffic controls on the approach, pavement markings, and all signs except the crossbuck and/or signal assembly. Figure 11·11 depicts the typical railroad advance waming
signs as specified by the Texas MUTeD. Figure 11·12 shows the railroad crossing (crossbuck) sign, flashing light signal, and automatic gate typically used at grade crossings. The crossbuck
assembly consists of the crossbuck, a multitrack sign if appropriate, and the "exempt" sign if required. The exempt sign informs drivers of special vehicles, transit buses, schOOl buses
carrying children, or vehicles carrying hazardous materials that a stop is not required except when railroad eqUipment is approaching or occupying the crossing. The Intermodal Surface
Transportation Efficiency Act of 1991 (lSTEA) legislation has added revisions to the Texas MUTeD to allow the use of STOP signs or YIELD signs at railroad crossings. When adequate sight
distance cannot be maintained at a passive grade crossing, stop signs are an effective countermeasure. The signs can be posted at any highway-rail grade crossing without automatic traffic
control devices with two or more trains crossing per day. For other crossings with passive protection, STOP or YIELD signs may be used after need is established by a traffic engineering
study. The study should take into consideration such factors as: volume and character of highway and train traffic, adequacy of stopping sight distance, crossing accident history, and
need for active control devices. For all highway-rail grade croSSings where STOP and YIELD signs are installed, STOP AHEAD or YIELD AHEAD advance waming Signs shall also be installed.

highway-rail grade crossings for the installation of STOP and YIELD signs. Research by FHWA and FRA indicates that under pertinent circumstances STOP signs may be significantly more
effective in preventing highway-rail collisions than crossbucks alone. However, both agencies recognize that other highway traffic safety concems must be considered when determining
proper signage at individual locations. Also, it has been shown that there is low motorist recognition and understanding of the crossbuck as a traffic control device alone and that supplementary
signage at crossings not equipped with automated waming devices should be considered. FHWA and FRA recommend that the following general factors be considered when reviewing a crossing
for possible STOP or YIELD sign installation: • Volume, type, and speed of highway traffic; • Frequency, type, and speed of trains; • Number of tracks; • Intersection angles; • Adequacy
of stopping sight distance; • Need for automated waming devices; and • Crossing accident history. The agencies recommend that the following speCific factors be applied in determining
first priority with respect to new STOP sign installations. Fundamental indications: It is recommended that the following considerations be met in every case before a STOP sign is installed:
1. Local and/or State police and judicial officials will commit to a program of enforcement no less vigorous than would apply at a highway intersection equipped with STOP signs. 11-25

2. Installation of a STOP sign would not occasion a more dangerous situation (taking into consideration both the likelihood and severity of highway-rail collisions and other highway
traffic risks) than would exist with a YIELD sign. Positive indications: Anyone of the following conditions indicate that use of STOP signs would tend to reduce risk of a highway-rail
collision. It is recommended that the following considerations be weighed against the contra-indications below: 1. Maximum train speeds equal or exceed 30 mph (a factor highly correlated
with highway-rail accident severity). 2. Highway traffic mix include buses. hazardous materials carriers and/or large (trash or earth moving) equipment. 3. Train movements are 10 or
more per day, 5 or more days per week. 4. The rail line is used by passenger trains. 5. The rail line is regularly used to transport a significant quantity of hazardous materials. 6.
The highway crosses two or more tracks, particularly where both tracks are main tracks or one track is a a passing siding that is frequently used. If Federal-aid funds are used in a
highway-rail grade crossing improvement project with multiple main line tracks. gates and flashing lights are required (23 CFR 646.214). 7. The angle of approach to the crossing is skewed.
8. The line of sight from an approaching highway vehicle to an approaching train is restricted such that approaching traffic is required to substantially reduce speed. Contra-jndications:
Factors to be weighed in opposition to STOP signs: 1. The highway is other than secondary in character. Recommended maximum of 400 ADT in rural areas, and 1,500 ADT in urban areas. (If
any of the positive indications apply to a 11-26 
crossing with traffic counts in excess of these levels, strong consideration should be given to installation of automated waming devices). 2. The roadway is a steep ascending grade to
or through the crossing. sight distance in both directions is unrestricted in relation to maximum closing speed. and the crossing is used by heavy vehicles. A crossing where there is
insufficient time for any vehicle, proceeding from a complete stop, to safely traverse the crossing within the time allowed by maximum train speed, is an inherently unsafe crossing that
should be closed. Although STOP and YIELD signs are permissible traffic control devices within established conditions or warrants, proper use at grade crossings is critical to improving
the motorist's understanding of the message that is displayed. As reported in the December 1994 issue of IIJli Highway & Rail Safety Newsletter, a study of STOP signs in Alabama and
Georgia by Archie Bumham reported that 82 percent of the drivers were confused of semi-confused by the STOP signs at railroad-highway grade crossings. Bumham found that of 862 vehicles
18 percent came to a full stop, 50 percent made a slow rOiling stop, and 32 percent did not stop at all. Based upon these observations Bumham concluded that "one of the most widely recognized
and often overlooked traffic safety axioms is the prinCiple that over use provokes abuse. For a traffic control sign, signal, or pavement marking to be of value it must not be overused."
Regarding protection devices for signs and signals. FHWA revised the railroad-highway crossing guidelines. Guardrails are not recommended to shield waming device supports because a vehicle,
if struck by a train, could strike the guardrail and be redirected towards the train. A circular metal beam guard fence is allowed to shield waming signals under appropriate circumstances.
11-27 
Pavement markings refers to markings applied or attached to the surface of a roadway for the purpose of regulating, waming, or guiding traffic. The markings in advance of a grade crOSSing
shall consist of an "X', the letters "RR', a no passing marking (2-lane roads), and certain transverse lines. Identical markings shall be placed in each approach lane on all paved approaches
to grade crossings where grade crOSSing Signals or automatic gates are located, and at all other grade crossings where the prevailing speed of highway traffic is 40 mph or greater. FenCing
Fencing that encloses the railroad right-of-way may be used to restrict access. It can be an effective deterrent to indiscriminate use, according to FHWA, if placed on one side of the
right-ot-way with its height from four to eight feet. One of the three main objections to fencing is the cost which may be in excess of $100,000 per mile for chain link fencing, according
to local rail carriers. Secondly, according to the FHWA Railroad-Highway Grade Crossing Handbook. it does not bar pedestrian entrances at crossings. Finally, maintenance costs would
be another budget consideration for either party. The absence offencing at railroad rights-of-way would not implicate a city for potential tort liability. Therefore, the Task Force recommends
that fencing in urban areas be considered a site-specific issue, studied and negotiated with the affected railroad operators and the local govemment. Grade Crossing Materials Several
general guidelines are discussed in this section to assist a city in determining a crossing surface management process. These guidelines may help to define the most appropriate grade
crossing surface for a specific site. The Railroad Maintenance Work Group concurs cities may request the railroads to upgrade the standard timber crossings. Asphalt and timber crossings
are 11-28 
the most common surface materials and represent over 80 percent of all public crossing surfaces in Texas. It has been found that asphalt crossings and timber crossings have the shortest
expected life span. Asphalt and timber crossings are specified for crossings with very low ADTs but may range up to 7,500 ADT without heavy truck traffic and still be cost effective.
The Florida Department of Transportation completed a materials selection handbook in 1984 to develop criteria for the selection of crossing surfaces. The expected life of each surface
type was reduced proportional to an increase in ADT, percentage of trucks related to total traffic, multiple track spacing, and gross train tonnage. The annualized cost was then determined
based on costs per linear foot and surface type as shown in Figure 11-13. Listed below are several key factors, not speCifically ranked in any order, that should be considered in determining
an appropriate grade crossing surface: • Highway Trafficlfunctjonal Classification -The volume and capacity, vehicle type, and speed of the highway traffic affects the loading the crOSSing
surface must suport • Special Vehicles -Crossings used regularly by special vehicles, (e.g. school buses, transit buses, hazardous material carriers) should be given very careful consideration
• Railroad TrafficfIrack Classification -The number of trains, train type and train speed as well as the weight and size of the rail affects the loading that the subgrade and supporting
track will bear • EXPected Service Life of Crossing SYrface -Dependent on adequate ballast tamping and butting onto the crossties with replacement of the weak crossties • Accident History
-Particularly accidents related to the condition of the surface • 􀁾-Initial construction cost, replacement cost, and maintenance cost • Engineering Judgment 11-29

The life of a crossing surface depends on the volume and weight of the highway and rail traffic. The highway traffic not only dictates the type of grade crossing surface to be installed,
but obviously has a major influence on the life of the crossing. The deterioration of the riding quality of a crossing surface results in increased vehicle operating cost, hazards and
inconvenience to highway traffic. Rail traffic also contributes to the deteriorating effect on the service life of the crossing in that it causes the need to repair or replace the highway-rail
crossing surface. Railroad traffic damages the crossing surface through vibration or uplift in front of the wheels reducing the life by 5 to 50 percent depending on the surface type.
If cities maintain road facilities with traffic volumes greater than 5,000 ADT and prefer to upgrade the standard timber crossing provided by railroads, the Railroad Maintenance Work
Group concurs that railroads will install the upgraded crossing materials if the local agency purchases the materials on a negotiated labor cost basis. On state maintained highways,
TxDOT specifies timber surface materials for a crossing for vehicle traffic less than 2,000 ADT. The two principal high-quality crossing materials used in Texas are the rubber or concrete
panels. For railroad-highway crossings on the state maintained roads, TxDOT uses concrete or rubber panels for crOSSing materials for grade crossings with vehicle traffic greater than
2000 ADT. These materials provide a durable, smooth riding surface with a long-lasting surface life. Most railroads prefer full depth crossings without shims in main or branch line applications.
Some railroads are adopting concrete panels as their standard.crossing surface material. One of the principal "high-type" crossing surface materials is the rubber panel. This type of
crossing surface consists of molded rubber panels usually steel-reinforced with a pattemed, antiskid surface. The panels can be removed or replaced for track maintenance. The rubber
panels 11-31 
are made in versions that are either full-depth or shimmed to the correct surface height. Rubber was marginally preferred over concrete panels because of its lower annualized cost due
to its high service life. Prices of crossings constructed in 1989 from 100 percent virgin rubber ranged from $175-$275 per track-foot, according to local city engineers. Further information
conceming virgin rubber indicates it has the added advantage of being quiet in noise-sensitive areas. The Louisiana Department of Transportation and Development also had a high preference
for rubber crossings according to the FHWA Highway-Railroad Grade Crossing Material Selection Handbook. Currently, some railroads are installing prefabricated concrete panel crossings
on all main lines and selected spur tracks. Some prefabricated concrete panel crossings in the Westem states have lasted more than 15 years. Prices of crossing materials vary from $90-$175
per track-foot for prefabricated concrete. In a comparison with 100 percent virgin rubber, concrete proved to be more cost efficient in maintenance fees. The prefabricated concrete panels
generally withstand normal rail maintenance better than rubber which is often damaged. Poured-in-place concrete is not recommended because it can cause track access problems for railroad
companies during routine track maintenance operations. The Work Group recommends that 100 percent virgin rubber or prefabricated concrete materials be utilized for crossings with more
than 5,000 ADT or heavy truck traffic greater than 10 percent of the total traffic. Ref!ectorized Tape and lIIymination The Texas House Bill (H.8.) 2681 of 1991 mandated that every grade
crossing currently without active warning devices have 2" -4" reflectorized tape installed on the support post and back of 11-32 
every single-sided crossbuck sign. This law requires TxDOT to be responsible for this portion of the crossbuck assembly. TxDOT representatives have the option of installing the material
with their crews or supplying to local govemments the reflectorized tape for local staff installation. Any replacement of crossbucks will be completed by the rail carrier with new double-sided
reflectorized crossbuck signs. These will ultimately phase out single-sided crossbucks with reflectorized tape on back. Backing up the far-side crossbuck with another reflective crossbuck
and reflectorized support post has two important advantages. First, it provides redundancy to assist drivers in detecting the crossing. Second, it will reflect vehicle headlights back
through the gaps between the rail cars. The on-off effect creates a strobe light (flicker) similar to an active warning device. If reflectorization has not reduced accidents, the Railroad
Maintenance Work Group recommends the adoption of crossing illumination guidelines for crossings involving nighttime railroad operations or crossings with nighttime train-vehicle accidents
as described in the FHWA Railroad-Highway Grade Crossing Handbook. According to the Handbook, crOSSing illumination may be effective under the following conditions: • night time train
operations • low train speeds • blockage of crossings for long periods at night • accident history indicating that motorists often fail to detect trains or traffic control devices at
night • horizontal and/or vertical alignment of the highway approach which does not allow the vehicle headlight to fall on the train until the vehicle has passed the safe stopping distance
• long dark trains (e.g., unit coal trains) • restricted sight distance or stopping distance in rural areas 11-33 
• existing "humped" crossings where the large vertical grade change of the approach lanes can allow oncoming vehicle headlights to be visible under the train • low ambient light levels
Recommendations for the placement and type of floodlights or luminaries are available in the FHWA Roadway Lighting HandboOk. It is desirable to have at least two luminaries provided
at the crossing, with one on each side of the track. Mounting height should be between 30 and 40 feet. Illumination should be a distinctive color and distribution so that it clearly
distinguishes the crossing amongst other street lighting. In rural areas, some lighting should be directed down the track to light the sides of railroad cars. Track 􀀧􀁮􀁳􀁰􀁥􀁣􀁴􀁩􀁾􀀠Railroad
carriers are responsible for track inspections on a set schedule as outlined in the Code of Federal Regulations (CFR). These nationwide safety regulations are solely based on track conditions,
track curvature, superelevation, and roadbed conditions with different standards for six classes of tracks. The FRA monitors the rail operators' compliance with these maintenance and
operating standards and appears to have the sole legislative authority to fine railroads if noncompliance occurs, according to the Railroad Commission of Texas (RCl). This inspection
procedure appears to have occurred based on the supremacY clause of the U.S. Constitution, which specifies when federal law conflicts with state or local law, the federal law must control.
Thus, a local city's inspection of tracks appears to have no enforcement validity unless the RCT inspects the track on the city's behalf. A city's attempt at inspection has been found
as a restriction on railroad operations and would be in violation of interstate commerce, a concept that Congress hoped to encourage in the Federal Railroad Safety Act of 1970. The Work
Group 11-34 
recommends that track inspections, where necessary on behalf of local govemments, be coordinated with FRA or RCT officials. Visual Obstructions The clearance of visual obstacles at railroad-highway
grade crossings for each sight triangle of the crossing's four quadrants is recommended by the Work Group as outlined in revised Railroad Commission of Texas regulations. The RCT require
vegetation control and permanent obstruction clearance for 250 feet as measured from the centerline of each crossing for public crossings equipped with cross bucks. When the railroad
right-ot-way is fenced, compliance would be deemed if the vegetation is controlled up to two feet from the fence. "Vegetation" includes grass, bushes, shrubbery, and trees having a diameter
of six inches or less. "Public crossings" include an approach with at least one public roadway. Obstructions also include trains, cars, or equipment standing closer than 250 feet from
the centerline of any grade crossing equipped with passive waming devices. Railroad operators in violation of this rule are subject to fines unless a closer distance could not be avoided.
Billboards and signs which are legally permitted by the state or a political subdivision are not necessarily permanent obstructions as long as they do not block the motorists' View of
approaching trains, according to FHWA. Permanent buildings in existence prior to the effective date of this ruling are exempt from this requirement. Railroad companies are responsible
to bring their right-ot-way vegetation into compliance. However, a variance may be applied for by rail carriers concerning nonconforming vegetation and permanent obstructions under the
current RCT regulations. Clearing brush or weeds from a 11-35 
grade crossing provides adequate sight distance at a crossing and can also provide a better preview of the crossing for approaching drivers. The Texas Department of Transportation sponsored
a research report in 1994 through the Texas Transportation Institute to study the impact of sight distance as an additional variable to the Texas Priority Index for railroad-highway
grade crossings. The report, by Fambro, Klaver, and Cooner, evaluated both sight distance as criterion for ranking railroad-highway grade crossings for improvement. In studying train
involved accidents over a five year period, Fambro found that sight obstructions could have been a contributing factor nearly 50 percent of the time and that the majority of passive
railroad-highway grade crossings have at least one sight obstruction. The research report recommends the use of a sight distance variable to help TxDOT engineers identify those crossings
most in need of improvement. TxDOT will evaluate the findings of this report and may incorporate some or all of the recommendations into practice in the Texas Priority Index. CROSSING
RELOCATIONS, CONSOLIDATION OR CLOSURE The Federal Railroad Administration has set a national goal to close 25 percent of the nation's highway-rail grade crossings by the year 2000. Texas,
with almost 20,000 highway-rail grade crossings, has the highest number in the nation. Reducing the number of crossings through relocation or rerouting of the highway, or closure of
the highway crossing represent "low cost" safety improvements. Crossing consolidation is desirable when there are many redundant crossings in a particular jurisdiction. Closure of a
crOSSing may be required when the grade crossing is angled in such a way that the sight distance is restricted. Additionally, any restricted or obstructed sight distance that cannot
be corrected for the motorist approaching a railroad grade crOSSing will warrant closure. 11-36 
The number of crossings needed to carry highway traffic over a railroad in a community is influenced by many of the charactenstics of the community itself. A study of highway traffic
flow should be conducted to determine ongin and destination points and needed highway capacity. Access issues must be studied to determine the impact on emergency vehicles, ambulances.
fire trucks. and police. Thus. optimum routes over railroads can be determined. Highway operation over several crossings may be consolidated to move over a nearby crossing with flashing
lights and gates or over a nearby grade separation. Altemative roates should be within a reasonable travel time and distance from a closed crossing. The altemate routes should have sufficient
capacity to accommodate the diverted traffic safely and efficiently. The 1986 Railroad-Highway Grade Crossing Handbook suggests that by using a systems approach several crossings in
a community or rail conidor could be improved by the installation of traffic control devices while other crossings are closed. However, the various factors that should be considered
to identify those crossings that should be closed are difficult to establish. Currently. there are no Federal restrictions or standards on how many or what types of crossings should
be consolidated within a given area. The following criteria, taken from the 1994 FRA report Rail-Highway Crossing Safety Action Plan Support Proposals, have been found useful for selecting
crossings for consolidation: 1. Consolidate crossings where there are more than four per mile in urban areas. and one per mile in rural areas and an altemate route is available. 2. Consolidate
crossings which have fewer than 2.000 vehicles per day and more than two trains per day and an aHernate route is available. 3. Eliminate crossings where the road crosses the tracks at
a skewed angle or where the track is curved. 11-37 
4. Link construction work with eliminations. This linkage will be especially important when upgrading rail corridors for high speed trains. 5. When improving one crossing (by grade separation
or installation of automated waming devices), consider eliminating adjacent crossings and rerouting traffic from these croSSings to the improved crossing. 6. For every new crossing built,
consolidate traffic from two or three other crossings. 7. Eliminate complex crossings where it is difficult to provide adequate waming devices or which have severe operating problems
(e.g., multiple tracks, extensive switching operations, long periods blocked, etc.). The 1994 Highway-Railroad Grade Crossings: A Guide to Crossing Consolidation and Closure by the Federal
Railroad Administration provides useful information agencies to assist them in grade crossing consolidation projects. The 􀁾addresses the issue of local opposition crossing closure.
The 􀁾offers strategies to win local support based on actual crossing consolidation projects. Past experience shows that even when communities support crossing conSOlidation, they may
oppose proposed changes in traffic pattems. In these cases, "trade-offs,' such as upgrading other crossings in the area of the targeted closure, have been successful. TEMPORARY CROSSING
CLOSURESIt is recommended by the Railroad Maintenance Work Group that cities or counties be given fille. working days notice by the railroad operator for partial or full street closures due
to maintenance or rehabilitation of the railroad crossing unless an emergency situation prevails. This notice will allow local govemments to coordinate detour routes if warranted. It
is also the recommendation of this Work Group that any work area traffic control be coordinated between the local govemment and the railroad. 11-38 
BICYCLE CROSSINGS Bicycle paths across railroad tracks present several special problems. There are some relatively simple and cost-effective treatments available for the problems cyclists
encounter at railroad grade crossings. The reduction of lane width at a crossing can affect passage of bicycles across the tracks. The 1986 Railroad-Highway Grade Crossing Handbook specifies
that the crossing should be sufficient to extend at least one foot beyond the edge of the highway pavement, including any paved shoulders on the highway approaches to the crossing. Also,
depending on the crossing angle (the skew of the tracks in comparison with the bikeway or traveled lane) and the condition of the tracks, a cyclist may lose control of the vehicle if
a wheel becomes trapped or violently redirected in the flangeway. The surface materials and the flangeway depth and width must be examined to determine if the crossing is safe for the
cycling public. The more the crossing deviates from the ideal 90-degree crossing, the greater the potential for a cycle wheel to be trapped or violently redirected in the flangeway.
If the crOSSing angle is less than 45 degrees, engineers should consider widening the bikeway to allow sufficient width to cross the tracks at a safer angle. Maintenance personnel should
preserve the crossing surface to be as smooth and level as possible in order to provide for the safest passage for the cyclists. Another potential problem exists in the communication
of an approaching train to the cyclists at actively controlled railroad-highway grade crossings that use flashing lights. The Handbook recommends the use of a crossing bell to supplement
other active traffic devices to help alleviate the detection problem sometimes encountered by cyclists. The Handbook goes on to say that other than smooth surface treatments, there are
no special controls for these special vehicles. 11-39 
However, if a bicycle trail crosses tracks at-grade, the bicyclist should be warned of this with sUitable markings and signs. AMERICANS WITH DISABILITIES ACT The Americans with Disabilities
Act (ADA) establishes accessibility standards for new construction and alterations of state and local government facilities covered by the ADA One small part of the Interim Final Rule
published by the Architectural and Transportation Barriers Compliance Board relates to railroads. Section 14.2.1 of the Accessibility Guidelines for Buildings and Facilities sets out
minimum requirements for new construction of public sidewalks. Among other things, the interim rul specifies: "Where public sidewalks cross rail systems at grade, the surface of the
continuous passage shall be level and flush with the rail top at the outer edge and between the rails. The horizontal gap on the inner edge of each rail shall be the minimum necessary
to allow passage of wheel flanges and shall not exceed 2 1/2 inches maximum." The effective date of of this rule was December 20, 1994. TOLL-FREE NUMBER IN TEXAS FOR REPORTING CROSSING
SIGNAL PROBLEMS The Texas Department of Public Safety (DPS) conducts a crOSSing signal reporting procedure for the public in Texas. The provision of a toll-free number permits any person
to report any problem or malfunction with a railroad-highway signalized grade croSSing on the state or federal highway system. Analysis of logged calls by the Railroad Commission of
Texas and the DPS has primarily indicated problems with improper signal operation, excessive crossing delays for motorists, and poor crossing conditions. Every signalized railroad-highway
grade crossing has a sign showing both an identification number and toll-free telephone number for reporting safety problems. Figure 11-11 shows the 11-40 
standard malfunction warning sign which is designated under the MUTCD as the R15-4 sign. The identification number is a unique, six-digit code number that identifies its' location and
which railroad has maintenance responsibility. The DPS crossing safety telephone number is 1-800-772-7677 and is attached to metal signal posts at the crossings. When the public is reporting
a problem, the U.S. Department of Transportation (DOn crOSSing number, together with any alphabetic characters, should be given to the answering DPS dispatcher. Cities can participate
in this DPS signage program for signalized crOSSings. The typical cost of these signs is approximately $15 with railroads offering to install these signs or supervise their installation
on existing railroad Signal posts if the city is willing to pay for the materials. The RCT has confirmed that funding and installation are available from TxDOT District offices for any
public rail-highway crossing with railroad Signals. The local jurisdiction having road authority should contact the appropriate TxDOT District office and railroad company to arrange
for funding and installation of the signs. The Railroad Maintenance Work Group recommends that where local funds permit, city governments at their discretion arrange for U.S. DOT inventory
number signs or stencils to be placed on signal posts at grade crossings. The signs' manufacturing costs would be absorbed by the city and installation arranged through the railroad
operator. 11-41 
III. OPERAnONS Railroad operations include items of mutual concem for local government officials, the general public, and the railroad operators, The issues can be summarized into economic,
safety, and environmental considerations. For the North Central Texas area, local governments and railroad representatives have identified seven major issues as follows: • speed restrictions
• size restrictions • blocked crossings • railroad noise related to adjacent land uses • motorist education • responsibilities of motorists at grade crossings • police enforcement at
activated warning device grade crossings Recommendations for these selected items are presented by the Railroad Operations Work Group to the Railroad Coordination Task Force for inclusion
as regional operation guidelines for rail conridors, SPEED RESTRICTIONS Historical Development Historically, railroads came to the centers of existing communities because the communities
wanted them to enter and provide transportation between them and the rest of the country. In sparsely populated areas, cities were built up around railroads. In today's environment,
especially with high vehicular traffiC, conflicts have arisen over the railroads' location in urbanized areas. 
From the community and motorists' viewpoint, the railroad is currently a dividing force providing safety hazards, vehicular delays, congestion, potential emergency vehicle response time
delays, and blocked street crossings. The resulting frustration encourages impatient motorists to run through closed automatic gates when trains are in dangerous proximity. Thus, some
communities have imposed railroad speed restrictions in the interest of public safety, From the rail carriers' perspective, arbitrary speed restrictions are undesirable because of the
delays and fuel costs incurred for trains slowing to pass through the community. It makes the railroads less competitive because lower train speeds and higher costs enable the airline
and trucking industry to attract a larger percentage of the transportation market. However, the prevalent central city location still proves advantageous for the railroads. The rail
corridors can also provide easements for utility companies and fiber-optic communication services to enter the central cities. Historically, municipal speed restrictions for railroads
did not occur in great numbers until the late 1890s when the number of crossings and number of rail/motor vehicle accidents increased because of the conflicting surface transportation
modes. Initially, many states and cities demanded that the railroads, who were responsible for the crossings, take immediate action to eliminate hazardous crossings. Numerous laws, ordinances,
and regulations were adopted to enforce these community demands, but there was neither regulation uniformity, a division of responsibilities, nor an aUocation of costs. Existing Railroad
Operating Speeds Existing railroad operating speeds in the DaUas-Fort Worth region are govemed by the FRA track class standards, mainten,mce standards, and individual railroad operating
policies which may 111-2 
adopt existing city railroad ordinances. A summary of city railroad ordinances for Dallas, Fort Worth, Arlington, Grand Prairie, Irving, Garland, and Farmers Branch are shown in Figure
111-1, Tabulated FRA track classes and related maximum allowable operating speeds are shown in Figure 111-2. Several city ordinances illustrate the diversity between their allowable
train operating speeds and the FRA maximum allowable operating speeds in the Dallas-Fort Worth region. For instance, the Dallas ordinance allows crossings with passive waming devices
to have limited speeds of 10-25 mph while Farmers Branch allows 40 mph citywide, Federal Court Judgments In order to give some legal context to the differences in current railroad operating
speeds, a review of case law is appropriate, In 1893 the U.S. Supreme Court, in the precedent-setting case of New york and Northeastem Railway vs. Town of Bristol, upheld the constitutionality
of a Connecticut statute that required railroads to pay 75 percent of the costs to improve or eliminate crossings where the highway was in existence before the railroad. In addition,
if the road was constructed after the railroad, the railroad was still required to pay 50 percent of such costs. This so-called "Senior-Junior" principle was followed by the courts in
several other states to determine the railroads' responsibilities. Until 1935, the U.S, Supreme Court adhered to the position that a railroad company should allocate a portion or all
of the expense for the construction, maintenance, rehabilitation, or elimination of public railroad-highway grade crossings. This was partially due to the dominance and financial status
of the railroads during the first three decades of this century. However, funds from federal industrial recovery acts provided monies for separation of the railroad-highway grade crossings
and installation of rail crossing traffic control devices. By this time, the public altitude 111-3

shifted, and the U.S. Supreme Court's decision, according to the Railroad-Highway Grade Crossing Handbook, reflected: The railroad has ceased to be the prime instrument of danger and
the main cause of accidents. It is the railroad which now requires protection from dangers incident to motor transportation. Precedence of Federal Railroad Administration Track Classification
The enactment by Congress of the Federal Railroad Safety Act of 1970 was intended to provide uniform, nationwide railroad safety standards. Authority for individual states to further
regulate railroads was given only under speCial circumstances. Congress sought to eliminate the undue burden on interstate commerce and railroads by limiting state and local administrative
and judicial systems in several areas affecting rail operations. Pursuant to the Act, the FRA adopted train operating speeds in conjunction with the adoption of track. roadbed. and signal
standards. The FRA established train speeds between 10 and 110 mph as summarized in Figure 111-1. In Baltjmore and Ohio Railroad Company vs. the City of Piqua, Ohjo. a federal court
in 1986 held that a city's attempt to establish railroad operating speeds below FRA standards was preempted by federal law and therefore invalid. Railroads are willing to cooperate with
different levels of govemment to institute safe and practical train speeds, motor vehicle speeds, traffic control devices. and adequate sight distances to reduce railroad and highway
crossing hazards. Amtrak has worked with local govemments on a railroad corridor upgrade program to raise operating speeds of the FRA Class 4 main line between Dallas and Houston. Selected
croSsings are being upgraded by standard federal rail-highway crossing safety improvement matching funds. They have been successful in revising operating speeds in conjunction with the
counties of Dallas and Carson, plus the cities of Ennis. Wilmer. Palmer. Hutchins. and Houston. Houston currently has passenger train operating speeds of between 30 and 60 mph. 111-6

State Intervention for Local Crossing Hazards Allowance was made for state intervention on behalf of cities such that, "A state may adopt or continue to enforce an additional or more
stringent law, rule, regulation, order, or standard relating to railroad safety when necessary to eliminate or reduce an essentially local safety hazard, when not incompatible with any
federal law, nor creating an undue burden on interstate commerce," This judgment was made in the precedent-setting case of Sisk VS, National Railroad Passenger Corporation (Amtrak),
647 Federal Supplement 861 (Federal District Court, Kansas, 1986). The case further argued that the supremacy clause in the United States Constitution established that when federal law
conflicts with state or local law, the federal law must control. However, Congress did allow the states to act on behalf of cities concerning local railroad hazards to reduce train operating
speeds due to, for example, problems with sight distance, road geometry, proximity of school children, school bus routes, or emergency vehicle routes. The RCT supports this judicial
position of state intervention on behalf of local cities at unprotected crossings and is recommending that modifications to railroad speed limits be achieved on a site-specific basis
in conjunction with the Commission and the affected rail operator. Harmonic Oscillation Documentation from the Texas Transportation Institute (TIl). entitled A General OVerview of Railrpad
Safety in Texas, states that for railroad operating speeds between 12 and 25 mph, harmonic oscillation or car rocking can occur with a potential for derailment, particularly along extended
portions of track at a lower speed range. Consideration should be given to this problem, according to the Work Group, before any new railroad speeds below 25 mph are adopted. 111-7 
Accident Data The national office of the FRA in Washington, D.C. publishes accident statistics annually. Those statistics and others utilized in accident analysis according to the FHWA,
should be surveyed over a minimum three-to five-year period to determine trends, such as those necessary in before-and-after crossing improvement studies. TxDOT analyze a fIVe-year period
of traininvolved accident statistics reported to the Texas Department of Public Safety when determining which crOSSings are eligible for site diagnostics and FHWA crossing safety upgrade
funds. Analyzing the Texas region in particular, grade crossing accidents between 1980 and 1988 are categorized by train-involved and nontrain-involved accidents occurring at crossings
with active (automatic gates or flashers) and passive (crossbuck) warning devices. Figure 111-3 illustrates the total number and percentage of Texas railroad accidents. Over 40 percent
of the crossing accidents occur at active warning devices and are nontrain-involved collisions. This indicates that drivers are confused over what the railroad signs and signals really
mean, especially for the younger and older adult population, according to TTL In detail, 3904 or 58 percent of total train-involved accidents occur at active warning device crossings.
The data also suggests that fatality rates are correlated to age groups, not only of young adults from 15 to 29 years but older adults of 75 years of age or higher. Both have significantly
higher fatality rates compared to the general population, as shown in Figure 111-4. Currently, no "train miles of travel" data are available from the national FRA database to normalize
accident rates as a function of train speeds. Recommendations Federal court cases indicate FRA track standards supersede other speed restrictions set by a state or city. The exception

distances or schools in close proximity to rail corridors. At that point. the state on behalf of the city can institute more stringent railroad operating speed standards if warranted.
The Railroad Commission of Texas recommends that communities and railroads try to resolve the grade crossing problem and then only consider speed restrictions on a corridor-wide basis.
If a certain grade crossing problem continues. then railroads may adopt railroad speed restrictions mutually agreed upon during negotiation with railroad operators on a IimHed site-specific
basis. Harmonic oscillation between 12 and 25 mph is also a technical issue to consider when seeking railroad speed limits. The rocking of trains which may occur at that speed range
can derail trains, especially over extended portions of track. Reconsidering accident data which indicates that rail accidents at grade crOSSings occur more with younger and older members
of the adult population, education targeted at these age groups may be very cost effective. Considering these four factors, the Work Group recommends that: • any existing city train
speed ordinances be repealed, and • railroads make available FRA track classifications for its tracks. SIZE RESTRICTIONS According to the judgment in the law case of Southem Pacific
Company vs State of Arizona (325, U.S. 761) in the Federal Supreme Court in 1945, any attempt by a state (and therefore any lesser governmental entity) to limit the length of trains
is an unconstitutional burden on interstate commerce. The express policy of .Congress was to promote an "economical national railroad 111-11 
system." The Task Force therefore considers that train size restrictions in local ordinances appear legally unenforceable and recommends procedures to shorten train lengths relative
to blocked croSSings be discussed with the railroads. FHWA railroad-highway crossing safety funds could be employed for grade-separated structures in this situation, and certain rail
carriers will offer to provide funding given the accident and derailment history of the croSSing. BLOCKED CROSSINGS A number of cities within their railroad ordinances have a law which
disallows the blocking of grade crossings for more than five consecutive minutes by a standing train. This is based on Article 6701 d-5 from Vemon's.Annotated Texas CMI Stalutes which
states: "An officer, agent, servant, or receiver of any railway corporation who willfully obstructs for more than five minutes at anyone time any street, railway croSSing, or public
highway by permitting their train to stand on or across such a crossing shall be fined not less than five nor more than one hundred dollars." This law was made effective in 1921 during
the 37th Texas Legislative session. Given the number of tracks and switches in urban areas which could potentially be blocked, jurisprudence would apparently determine whether a ''willful''
blockage of a crossing occurred. "Considering that urban areas with two grade crossings per mile are not unusual and train lengths can range from 5,000 to 7,000 feet, then potentially
three grade crossings could be blocked from a single train." Track circuitry involving either motion detector track circuits or constant waming-lime devices can improve motorist crossing
delays. When trains approach crossings at variable speeds or have significant switching movements, the constant waming time device uses an electronic system to ensure a 20-to 25-second
warning device activation time regardless of the train speed on the approach. If the train stops before the crossing, the signal is deactivated. The cost of a constant warning time device
ranges from $11,500 to $14,000 plus from $9,000 to $11,000 extra to install it 111-12 
compared to a motion detector. Motion detector track circuits utilize audio frequencies to detect when a train stops on the approach or moves away from a crossing. The crossing waming
system is then deactivated if the train is within normal approach limits. Grade crossing accident research reported in the November 1989 issue of Highway and Rail Safety Newsletter by
the Canadian Institute of Guided Ground Transport indicated that critical incidents result from the following conditions at the crossing: • unduly long waming times • long occupancy
times of the crossing by some trains • false alarms due to a signal malfunction or a signal placed in a fail safe status The researchers considered those events as precursors to the
tendency of drivers to deliberately violate the signals. Their analysis of video recordings indicated 25 percent to 33 percent of drivers were not aware that they are approaching a crossing.
Other drivers incurred an "unobeyable signal problem" where the signals flash and the driver was unable to stop the vehicle in a safe and comfortable manner. Finally, approximately 60
percent of the drivers had a speed variance approaching the croSSing where motorists either increased or decreased their speed thus increasing the inCidence of collisions at crossings
involving no train: either rear-end or front-end collisions with other vehicles resulted. The researchers concluded that for safety purposes at crossings, the drivers' decision to disobey
the Signal will be smaller if waming times are kept short including the time that moving trains occupy the crossing (that is when trains are short and move fast). They concluded efforts
toward risk control. short of grade separation. should include: • increasing crossing conspicuiiy, 111-13 
• reducing occurrence of unobeyable signals, • improving smoothness of crossing surfaces, • eliminating false alarms and excessively long waming periods, and • reducing total duration
of signal activation. Warrants and guidelines for these predictors have currently not been developed. The University of Tennessee Transportation Center has found that experimental four-quadrant
gate systems reduce the number of gate violations to almost zero. With the two-quadrant gate system, one or more motor vehicles drove around closed gates during 84 out of 100 train arrivals.
The experimental four-quadrant gates are not contained in the Texas MUTCD, although the regular gate locations with a center median prevents motorists from driving around activated gates.
The experimental four-quadrant gate system reduced 260 motorists per 100 trains from driving around gates to zero. The gates also reduced vehicles crossing between 10 to 20 seconds from
train arrival to zero. During the testing period, no motorist was trapped on the tracks, emergency vehicle operation was not impaired, no unreasonable delays were created for the motorist,
no public complaints were received, and retrofitting crossings with two extra gates was not difficult Researchers at the University of Tennessee recommend the following crossings for
four quadrant gates: • crossings on four-lane undivided roads • multitrack crossings where the distance between tracks is greater than the length of a motor vehicle • crossings without
constant waming time devices where train times are long and variable 111-111 
• crossings where there are hazardous materials trucks, transit buses, school buses, or high-speed trains • crossings with consistent gate arm violations or continuing accidents Appraising
the likelihood of this occurrence, the Railroad Ordinance Work Group has recommended the following: • as mentioned earlier, blocked crossings be analyzed from a corridor perspective
• motion detectors or constant warning-time track circuits be utilized as appropriate for crossings with heavy Switching operations or variable train speeds to minimize warning device
activation time • guidelines for grade separations, described in the Highway-Railroad Grade Crossing Handbook be adopted with encouragement of city initiatives to secure FHWA crossing
safety improvement funds and matching funds from railroads RAILROAD NOISE RELATING TO ADJACENT LAND USES The FAA regulates train noise by standards published in the CFR. For example,
locomotives manufactured prior to 1981 can have allowable "A-weighted" noise decibel levels of 96 dBA maximum when trains are in motion (fast). Locomotives manufactured mrDecember 1980
can have allowable noise levels of 90 dBA maximum when trains are in motion (fast). Additional noise regulations for switcher locomotives manufactured on or before December 31, 1979,
which operate in yards, are also available in the CFR. When stationary locomotive noise exceeds the receiving property limit of 65 dBA as shown in Appendix B, the locomotives are considered
in noncompliance. This situation will trigger a 30-meter or less noise level test on 111-15 
receiving properties. Overall, FRA enforcement efforts focus on abatement procedures that will achieve a reduction of receiving property noise levels to less than 65 dBA. The ICC also
has involvement with railroad noise control as a part of its enVironmental impact process. If a railroad project involves either new rail line construction, a discontinuance of passenger
trains, or certain rail mergers causing heavier train traffic (usually 50 percent greater train traffic or eight trains per day) on new, existing, or adjacent lines, the ICC's noise
rules would apply as written in 49 CFR, Part 1105. Again, the preliminary investigation would need to find environmentally significant decibel changes, as defined in 40 CFR 1508.27 for
the ,""n measure = 65 dBA for moving trains. An example of noise contours indicates that one loaded and one empty coal unit train (over 100 cars totaling 11,000 tons maximum) per day
transporting approximately four million tons of coal annually duringdaylight hours would have an ,""n of 65 dB with a contour commonly extending approximately 50 feet from the centerline of the track. Under a 12 million ton per year scenario, six trains
(three loaded and three empty) would increase the ,""n of 65 dBA contour line to 190 feet from the track centerline. This indicates that the ,""n of 65 dBA is a fair measure for noise
intrusion into sensitive land-use areas depending on the extent of residential dwelling units and other affected facilities such as libraries, hospitals, nursing homes, and schools.
The Work Group recommends that railroad noise of moving trains over 65 dBA next to residential property be the trigger for further noise measurements as defined in the CFR and resolved
by FRA procedures. 111-16 
MOTORIST EOUCA nON Grade Crossing Safety Facts Texas has recognized the importance of educating motorists of the potential hazards at highwayrail grade crossings by enacting legislation
to include grade crossing safety training in all defensive driving classes taught in Texas. In 1993 Texas had nearly 7 percent of the total national public and private grade crossings
with over 10 percent of the nation's grade crossing accidents and 12 percent of the nation's fatalities at grade crossings, meaning that a disproportionate number of accidents occur
in Texas. Details about Texas trainlvehicle accidents in 1993 indicate: • 52 percent occurred at signalized crossings, • 54 percent happened during daylight hours, • 61 percent involved
train speeds of less than 29 mph, • 52 percent happened Where the driver's view was unobstructed, • 66 percent occurred in clear weather, and • 25 percent involved vehicles running into
trains. A 1982 study by Berg, knoblach, and Hucke proposed that the occurrence of a vehicle-train accident was the result of a recognition, decision, or action error. The findings of
the study, as summarized by Fambro, Klaver, and Cooner in 1994, revealed that about 80 percent of the accidents investigated at crossings with crossbucks involved errors of driver recognition
and about 23 percent involved late recognition of a train that was already in the crossing. The study identified the principal contributing factors to vehicle-train accidents at crossings
as the lack of quadrant sight distance and low driver expectancy of train presence. Further, the study revealed that nearly 38 percent ofthe aCcidents investigated at crossings with
flashing lights involved driver recognition errors. Of these accidents the study showed that 81 percent of the drivers did not 111-17 
detect the signal when they were on the approach. Apparently, motorists who are involved in grade crossing accidents often do not exercise proper caution and do not observe motor vehicle
laws and will attempt to "run through" crossings even when the crossing gates are activated. Local governments should note that Amtrak requires the assignment of signal department employees
to investigate all reported signal malfunctions and the assignment of Amtrak police to be at the crossing until required inspections and repairs are completed on the signals. Operation
UfesaliM A national nonprofit program called "Operation Lifesaver" is an active, continuous public infonnation and education program to help prevent and reduce crashes, injuries, and
fatalities and improve driver performance at highway-rail grade crossings. Operation Lifesaver is needed because many drivers do not cross railroad tracks often enough to be familiar
with the warning devices designed for their safety. Driver inattention and impatience are the most common factors contributing to motor vehicleltrain collisions at highway-rail grade
crossings. The majority of 486 collisions in 1993 in Texas occurred during clear weather at crossings with active warning signals during daylight hours by trains going less than 29 miles
per hour. Operation Lifesaver reminds you to Look. Listen. and Live when approaching highway-rail grade crossings. Program emphasis is on the three E's: • Enforcement of existing laws
governing highway-rail grade crossings. • Engineering highway-rail grade crossings to provide the greatest safety by working with communities in their efforts to provide additional warning
devices. • Education of the driving public about the inherent dangers at highway-rail grade crossings. 111-18 
To enhance highway-rail grade crossing safety, Operation Lifesaver endorses the concept of reducing the number of crossings through elimination, consolidation, grade separation and restricting
the number of new crossings. Operation Lifesaver offers films, information, and speakers upon request to schools, civic groups, shopping malls, the media, governments, corporate driver
training courses, fleet vehicle drivers, and others. If cities or counties are interested in improving their local grade crossing safety, this Work Group recommends that they contact
the Texas Safety Association, a nonprofrt organization which helps coordinate grade crossing safety education in Texas. Their Austin telephone number is 5121343-6525. The Operation Lifesaver
Coordinator for Texas may be reached at the above number or fax 5121343-0746. The National Support Center for Operation Lifesaver, Incorporated may be reached toll free at 1-800-537-6224.
Legal Responsibilities of Motorists at Grade Crossings Drivers are subject to fines by law enforcement officers at the Department of Public Safety (DPS) for violating laws stated in
Article XI, Section 86 of Uniform Act in the Texas Motor Vehicle Laws regarding grade crossings. The Act slates: whenever any person driving a vehicle approaches a railroad grade crOSSing,
the driver of the such vehicle shall stop within fifty (50) feet but not less than fifteen (15) feet from the nearest rail of such railroad and shall not proceed until he can do so safely
when: • a clearly visible electriC or mechanical signal device gives warning of the immediate approach of a train. • a crossing gate is lowered or when a human flagman gives or continues
to give a signal of the approach or passage of a train, • a railroad engine approaching within approximately 1500 feet of the highway crossing emits a signal audible from such distance
and such engine by reason of its speed or nearness to such crossing is an immediate hazard, or • an approaching train is plainly visible and is in hazardous proximity to such such crOSSing.
111-19 
Drivers must stop by law for flashing lights, bells, or gates. If for some reason the lights are flashing and no train is in sight, the driver shoUld stop and look both ways, and then
proceed when they are sure the track(s) are clear. Pollee Enforcement at Activated Warning Device Grade Crossings Law enforcement officials are being urged to write citations for any
motorist or pedestrian who disregards activated grade crossing waming devices. Operation Lifesaver has a program that invites law enforcement officiers to ride on locomotives in order
to witness first hand what train engineers see everyday at highway-rail grade crossings where the motorists commonly fail to stop and remain behind activated warning devices such as
gates or flashers. Enforcement of existing laws governing highway-rail grade crossings pertains to driving past flashing signals, driving around automatic gates and flashers, failure
to obey yield or stop signs, failure for special vehicles to stop, and failure to yield right-of-way to a train at a passively controlled highway-rail grade crossing. Upon receipt of
a railroad crossing waming system malfunction, the railroad shall take appropriate action as required by 49 C.F.R. Part 234. Until repair or correction of the waming system is completed,
the railroad having maintenance responsibility for the waming system shall promptly initiate efforts to provide alternative means of warning highway traffic and railroad employees at
the subject crossing. The railroad must notify the law enforcement agency having jurisdiction over the crOSSing that is capable of responding and controlling vehicular traffic at the
crossing. In many cases, the law enforcement agency is the first to know of a waming system malfunction through public reports before the railroad company. 111-20 
The FRA has established regulations for waming system malfunctions at railroad-highway grade crossings. If at least one unifonned law enforcement officer provides waming to highway traffic
at the crossing, trains may proceed through the crossing at nonnal speed. If an appropriately equipped flagger or crewmember of the train is available to flag highway traffic to a stop,
the train may proceed through the crossing. The regulations specify that a Iraln may proceed at nonnal speed if there is a flagger for each direction of highway traffic or may proceed
with caution through the crossing at a speed not exceeding 15 miles per hour if there is only one flagger or train crewmember to stop highway traffic. Nonnal speed may be resumed after
the train has passed through the crossing. However, the train may not pass if there is no law enforcement officer or flagger or train crewmember available to stop highway traffic. 111-21

APPENDIXC GLOSSARY 
APPENDIXC GLOSSARY "A-Weighted" Noise Levels (dBA) -The weighting of sound which de-emphasizes lower and higher frequencies that are beyond the average human hearing range. Accident
Rate -1) The number of accidents, fatalities, or injuries divided by a measure of vehicle activity to provide a means of comparing accident trends through time. 2) The number of accidents
per crossing per year. Ballast -Gravel, broken stone, or slag placed between and under the ties of a railroad to give stability, provide drainage, and distribute loads. Bar Ditch -Can
be used as a drainage channel that carries water runoff from the track structure and adjacent land; forms part of the regional storm water and storm sewer system. Benefit-Cost Ratio
-The economic value of the reduction in fatalities, injuries, and property damage divided by the cost of the accident reducing measure. Branch Line -A secondary line of railroad usually
handling light volumes of traffic. Case Law -Law established by judicial decisions in particular cases, instead of by legislative action. Civil Statute -An enactment made by a legislature
for its citizens and expressed as a formal document. Constant Warning Time Track Circuit -Waming devices that will sense train speed in approach section of crossings equipped with gates
or flashers and select appropriate waming time. Crosstis -The wooden or concrete support upon which track rails rest and which holds them to gauge and transfers their load through the
ballast to the subgrade. Decibels (dB) -The unit of measurement for sound intensity, with zero dB corresponding roughly to the threshold of hearing. Exempt Sign -Informs drivers of vehicles
for hire, school buses carrying children, or vehicles carrying hazardous or flammable materials that a stop is not required except when railroad equipment is approaching or occupying
the crossing, or the driver's view of the sign is blocked. Fines -Minute particles of rock resulting from pulverized ballast or other rock aggregate. French Drain -A drainage trench
filled to ground level with fragments of brick or rock. Grads Separation -A crossing of two highways, or a highway and a railroad, at different levels. Green Board -A permanent railroad
sign which instructs an engineer to resume normal speed of the train. Hannonic Oscillation -The rocking motion of a train at speeds of 12-25 mph hour due to loads on staggered rail joints
occurring over extended distances. Horizontal Alignment -The angle of a roadway as it intersects another road or rail line; 9O-degree intersections are optimal for adequate sight triangles.
Lan Noise Level -The average noise level of both day and night hours where the night level between 10 p.m. and 7 a.m. is weighted an additional ten decibels (dB) to account for the increased
effect of noise perceived during these hours. Line-Haul -The movement of freight over the tracks of a railroad from one town or city to another town or city. Main Line -The principle
line or lines of a railway. C.l 
Main Track -A track extending through yards and between stations, upon which trains are operated by timetable, train order or both, or the use of which is governed by block Signals or
by centralized traffic control. Motion Detector Track Circuit -Detects train movement with an audio frequency whereby if a train stops on approach or moves away from a crossing, the
crossing warning system will be deactivated; often used for switching moves within normal approach limits. Nonnalize -In statistics to create a normal bell-shaped curve showing a distribution
of probability of a given event relative to an independent variable. Railroad/Highway Grade Crossing -The general area where a highway and a railroad cross at the same elevation and
includes the railroad right-of-way, roadway right-Of-way, and roadside signs and facilities. Pedestrian Crossing -A railroad-highway grade crossing that is used by pedestrians only.
Private Crossing -A railroad-highway grade crossing that includes a privately owned roadway utilized utilized only by the owner's licensees and invitees. Public CrOSSing -A railroad-highway
grade crossing that includes a roedway under the jurisdiction of, and maintained by, a public authority on at least one side of the track. Precedent -An adjudged case or judicial decision
that furnishes a rule or model for deciding a subsequent case that presents the same or similar legal problems. Priority Index -A mathematical equation used in Texas to rank the hazard
of an existing railroad grade crossing; it assists in the TxDOT determination of potential matching funding from FHWA Surface Transportation Program safety monies to be passed through
to local authorities. Pumping -The effect of poor drainage in the sub-ballast which causes mud to form, fouls the ballast, and allows the track to move vertically under heavy loads.
Railroad line Miles -The aggregate length of road of line-haul railroads. It excludes yard tracks, sidings, and parallel lines. Jointly-used track is counted only once. Railroad Track
Miles -Total miles of railroad track including multiple main tracks, yard tracks and sidings, owned by both line-haul and switching and terminal companies. Senior.Junior Principle -A
concept where a division of responsibility occurs between two parties depending on who or which was in existence first Tort Liability -Any private or civil wrong by act or omiSSion,
such as an accident which occurs from a person's negligence. Track -An assembly of rails, ties, and fastenings over which cars, locomotives, and trains are moved. Double or Multiple
-Two or more main tracks over which trains may travel in both directions. Single -1) The main track on a roadbed having one main track upon which trains are operated in both directions.
2) In multiple track territory, the process of running all trains, regardless of direction on one track while the other track is temporarily out of service. C.2 
Traffic Control Device -A sign, signal, marking, or other device placed on or adjacent to a street or highway 'by authority of a public body or official having jurisdiction to regulate,
wam, or guide traffic, Traffic Control Device (Active) -Those traffic control devices activated by the approach or presence of a train, such as flashing light signals, automatic gates,
and similar devices as well as manually operated devices and crossing watchmen, all of which display to motorists positive waming of the approach or presence of a train. Traffic Control
Device (Passive) • Those types of traffic control devices, including signs, markings, and other devices, located at or in advance of grade crossings to indicate the presence of a crossing
but which do not change aspect upon the approach or presence of a train. Traffic Markings -All lines, pattems, words, colors, or other devices, except signs, set into the surface of,
applied upon, or attached to the pavement or curbing or to the objects within or adjacent to the roadway, officially placed for the purpose of regulating, waming, or guiding traffic.
Train Miles of Travel -The total amount of distance each train travels in a given year. Vertical Alignment -The vertical slope of pavement or other material to allow for drainage. Wigwags
-An early active waming device which operates with a red symbol swinging on a fulcrum. C.l
