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.

Instructions for Completing the U.S. DOT Crossing Inventory Form
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.
