2. Year of Train Count Data

Figure 2-45: U.S. DOT-FRA Crossing Inventory Form Part II, Item 2

Note: In the event that there is a significant change in data, FRA recommends that this field be updated at that time rather than waiting for the next required 3-year periodic update.

Enter the year that the train count data was collected or last verified. If any train count data changes, the data field must be updated at time of submission.

3. Speed Of Train At Crossing

Figure 2-46: U.S. DOT-FRA Crossing Inventory Form Part II, Items 3.A. – 3.B.

Note: In the event that there is a significant change in data, FRA recommends that this item be updated at that time rather than waiting for the next required 3-year periodic update.

3.A. Maximum Timetable Speed (mph)
Enter the highest maximum timetable speed in miles per hour for any type of train movement over the crossing. If there are both freight and passenger train movements over the crossing, enter the highest maximum authorized speed (which will generally be the maximum authorized speed for passenger train movements). Permanent timetable speed restrictions should be entered, if applicable. This field must be greater than or equal to the maximum value in Item 3B, Typical Speed Range Over Crossing.

3.B. Typical Speed Range Over Crossing (mph)
Enter the typical minimum speed (“from”) through the crossing in miles per hour (mph). (This should be the typical minimum speed for normal operations through the crossing, not the minimum speed possible.) Enter the typical maximum speed (“to”) through the crossing. Neither value can be greater than the maximum timetable speed in Item 3.A.

4. Type and Count of Tracks

Figure 2-47: U.S. DOT-FRA Crossing Inventory Form Part II, Item 4
• Enter the number of “Main” line tracks. A mainline track is defined as a track extending through yards or between stations, upon which trains are operated by timetable or train order or both, or the use of which is governed by a signal system.
• Enter the number of “Siding” tracks. A siding track is defined as a track auxiliary to the main track used for meeting or passing trains.
• Enter the number of “Yard” tracks. A yard is defined as a system of tracks within defined limits used for the making up or breaking up of trains, for the storage of cars, and for other purposes over which movements not authorized by timetable or by train order may be made, subject to prescribed signals, rules or other special instructions. Spur track and lead track are included in this definition for purposes of this Inventory Form. Sidings and industry track are not included, nor is mainline track within yard limits.
• Enter the number of “Transit” tracks. A urban rapid transit track is defined as a track, on which a light-rail train, trolley, or streetcar moves passengers from
station to station typically within an urban area (and its suburbs), that is not connected with the general railroad system of transportation.
Enter the number of “Industry” tracks. An industry track is defined as a switching track, or series of tracks, serving the needs of a commercial industry other than a railroad. Note: Enter “0” for each track type specified that is not present at the crossing.

5. Train Detection (Main Track Only)

Figure 2-48: U.S. DOT-FRA Crossing Inventory Form Part II, Item 5

Enter a check to indicate the type of train detection equipment used to activate the warning system at the crossing for movements on the main track(s). More than one checkbox can be selected. If the crossing warning devices are not activated upon the arrival of a train, “None” should be checked.

The types of train detection equipment are:
• Constant Warning Time
• Motion Detection
• DC – Direct Current
• AFO – Audio Frequency Overlay
• PTC – Positive Train Control (please refer to 49 CFR § 236.1005 for a description of Positive Train Control systems)
• Other – for example when signals are activated manually by a watchman, or by means of other technologies
• None

6. Is Track Signaled?

Figure 2-49: U.S. DOT-FRA Crossing Inventory Form Part II, Item 6

Enter a check in the appropriate box to indicate whether or not the track is equipped with a block signal, cab signal, or train control system to govern train operations.

7. Monitoring Devices

Figure 2-50: U.S. DOT-FRA Crossing Inventory Form Part II, Items 7.A – 7.B

Enter a check in the appropriate box to indicate whether an event recorder and/or a remote health monitoring system is installed at the crossing.

These fields are required when the warning devices at the crossing include any of the following: four-quadrant gates, three-quadrant gates, or two-quadrant gates; or flashing lights.

Event Recorder means a device designed to resist tampering that monitors and records data on information at the grade crossing location such as (but not limited to) train speed, direction of motion, time, and distance over the most recent timeframe (e.g. last 24 or 48 hours) of the grade crossing warning system operation.

Remote Health Monitoring means an electronic system designed to remotely notify the railroad (typically the railroad signal maintainer or a trouble desk) that components of the automatic warning system are not functioning as intended.


4. Part III – Highway or Pathway Traffic Control Device Information


Figure 2-51: U.S. DOT-FRA Crossing Inventory Form Part III, Highway or Pathway Traffic Control Sign and Device Information

1. Are there Signs or Signals?

Figure 2-52: U.S. DOT-FRA Crossing Inventory Form Part III, Item 1
Enter a check in the appropriate box to indicate whether signs or signals are installed at the crossing.

2. Type of Passive Traffic Control Devices Associated With the Crossing


Figure 2-53: U.S. DOT-FRA Crossing Inventory Form Part III, Items 2.A. – 2.D.

2.A. Crossbuck Assemblies
Enter a count of the number of masts or posts with mounted crossbucks, not a count of the number of crossbuck signs. Two or more crossbucks mounted on a single post are counted as one unit. Include all masts with crossbucks without distinction as to the reflectivity type.

If the crossing has a train-activated warning device (flashing lights [cantilevered or mast mounted] and/or gates), do not count the individual number of crossbucks mounted on these devices.

As a matter of information, FHWA (via the MUTCD) requires that crossbuck assemblies be installed by December 31, 2019, or when adjustments are made to the individual highway-rail grade crossing and/or corridor, whichever comes first.


Note: A crossbuck assembly consists of a crossbuck sign and a “YIELD” sign, unless study indicates a “STOP” sign is necessary.
Figure 2-54: Example of a Crossbuck Assembly

2.B. STOP Signs (R1-1)
Enter the count of posts or masts with stop signs, regardless of any other type of warning devices. If there are two posts securing one sign, count them as one post.

Note: Do not include “STOP” signs from adjacent streets or roadways.

2.C. YIELD Signs (R1-2)
Enter the count of posts or masts with yield signs (MUTCD R1-2) at this crossing regardless of any other type of warning devices. If there are two posts securing one sign, count them as one post.

Note: Do not include “YIELD” signs from adjacent streets or roadways.
