Note: Pedestrian gate arms are only those that are part of the crossing signaling
system that are activated upon train detection.
Do not count:
 Pedestrian swing gates
 Post-mounted flashing light assemblies (3.D.)
 Crossbuck assemblies (2.A.)
3.B. Gate Configuration
Check the boxes for each type of gate configuration found at the crossing. A gate (for
purposes of the Crossing Inventory) is an automatically operated traffic control device
which, when activated into a horizontal position, is intended to physically impede users
such that they are discouraged from entering a particular grade crossing. Check only
one box on the left side of 3.B. (2 Quad, 3 Quad, or 4 Quad). On the right side, check
any applicable box. The choices are:
 “2 Quad” (two-quadrant gates) – a gate configuration featuring gates only on
entrance lanes leading onto the crossing. If a crossing does not have any gates
on any exit lanes leading off the crossing, then it is to be considered a “Two
quadrant gate” crossing. Note: A gated crossing on a one-way street is to be
considered a “2 Quad” gate configuration.
 “3 Quad” (three-quadrant gates) – a specific gate configuration featuring gates on
all entrance lanes leading on to the crossing, but with only one exit leading off the
crossing that is equipped with a gate.
 “4 Quad” (four-quadrant gates) – a specific gate configuration that features gates
on all entrance and all exit lanes at the crossing. When four quadrant gates are
activated and fully lowered, all entrance lanes and all exit lanes are blocked by
gates.

 “Full (Barrier) Resistance” gates – a gate-like device that is specifically designed
to physically prevent a highway vehicle from entering the crossing area when the
resistance gate system is fully deployed.
 “Median” gates (sometimes referred to as dual entrance gates) – a supplemental
gate installation located on a roadway’s median (to the left of the travel lanes)
that works in combination with a gate installed on the outside edge of the
roadway (to the right of the travel lanes) to jointly provide blockage of multiple
lanes on a single roadway approach to the crossing, with both gate arm tips
meeting (2-foot maximum gap) in the middle.
Note: This field is required if the number of gate arms in 3.A. is greater than 0.
3.C. Cantilevered (or Bridged) Flashing Light Structures (count)
Enter the count of cantilevered (or bridged) flashing light structures that are: (1) “Over
The Traffic Lanes,” and (2) “Not Over the Traffic Lanes.” Count the number of
structures, not the number of flashing light pairs. If cantilevered flashing light structures
are not present, enter “0”.
Check the appropriate box to indicate whether the flashing lights are Incandescent or
LED.
3.D. Mast-Mounted Flashing Lights (count of masts)
Enter the count of masts that have flashing lights. Count the number of masts, not the
number of flashing light pairs. The number of cantilevered structures are not included in
the count. If mast-mounted flashing lights are not present, enter “0”.
Check the appropriate boxes to indicate whether the flashing lights are Incandescent or
LED, and whether back lights and side lights are included.
When indicating the presence of mast-mounted flashing lights, do not enter the number
of crossbuck assemblies (2.A.) at the crossing.

3.F. Installation Date of Current Active Warning Devices
Figure 2-68: U.S. DOT-FRA Crossing Inventory Form Part III, Item 3.F.
This data field must be updated if train-activated warning devices are installed or
upgraded at a public highway-rail grade crossing after March 7, 2015. Using the list
below, enter the installation date for the first device encountered (moving from top to
bottom).
1. Four quad (or full barrier) gates
2. Three quad gates
3. Gates (normally two quadrant)
4. Flashing lights (standard and cantilever type units)
5. Highway traffic signals, wigwags, bells, or other activated devices
6. Special active warning devices (usually flagman)
Check the “Not Required” checkbox if the active warning devices were installed before
March 7, 2015 and the installation date is not provided. Completion of this data field is
not required for active warning devices installed prior March 7, 2015; however, if date is
known, it is recommended to enter it.

3.G. Wayside Horn
Figure 2-69: U.S. DOT-FRA Crossing Inventory Form Part III, Item 3.G.
Check the “Yes” box if the crossing is equipped with a wayside horn and enter the
month and year that the horn or system was installed. Check “No” if the crossing is not
equipped with a wayside horn.
3.H. Highway Traffic Signals Controlling Crossing
Figure 2-70: U.S. DOT-FRA Crossing Inventory Form Part III, Item 3.H.
Enter a check in the “Yes” box to indicate that there are highway traffic signals that
control highway traffic over the crossing, exclusive of other types of warning devices.
For purposes of Item 3.H., “highway traffic signals” refers only to train-activated redamber-green signals that control street traffic over the crossing. Do not count highway
signals controlling a nearby intersection even if they are interconnected with the
crossing warning devices.
Enter a check in the “No” box if there are none.
3.I. Bells
Figure 2-71: U.S. DOT-FRA Crossing Inventory Form Part III, Item 3.I.

Note: Pedestrian gate arms are only those that are part of the crossing signaling

system that are activated upon train detection.

Do not count:

 Pedestrian swing gates

 Post-mounted flashing light assemblies (3.D.)

 Crossbuck assemblies (2.A.)

3.B. Gate Configuration

Check the boxes for each type of gate configuration found at the crossing. A gate (for

purposes of the Crossing Inventory) is an automatically operated traffic control device

which, when activated into a horizontal position, is intended to physically impede users
