3.E. Total Count of Flashing Light Pairs

Enter the total number of flashing light pairs installed at the crossing, including back

lights, side lights, and where cantilever structures are present

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.

Enter the count of bells (either mechanical or electrical) present at the crossing as part

of the warning system. If there are none, enter “0.”

3.J. Non-Train Active Warning

Figure 2-72: U.S. DOT-FRA Crossing Inventory Form Part III, Items 3.J – 3.K

Check the appropriate box if there is “Flagging” or a “Flagman” (a member of the train

crew or other person who actively controls the flow of vehicular traffic using handsignaling devices or an Automated Flagger Assistance Device); “Manually Operated

Signals” (e.g., dual toned multi-frequency (DTMF)-controlled, push-button activated);

“Watchman” (a person assigned to provide warning that is not a member of the train

crew); or “Floodlighting” at the crossing. Only floodlighting—which is distinctive from

ordinary street lighting in intensity, light distribution, focus, or color—is to be reported.

Check “None” if applicable.

3.K. Other Flashing Lights or Warning Devices

Enter the count and type of any other special warning devices at the crossing. For

example, this would include wigwags if present. If none are present, enter a count of

“0”.

Figure 2-73: U.S. DOT-FRA Crossing Inventory Form Part III, Items 4.A. – 4.C.

4.A. Does nearby Hwy Intersection have Traffic Signals?

Check either the “Yes” or “No” box to indicate whether or not a highway-highway

intersection within 500 feet has highway traffic signals.

Note: The distance (500 feet or less) is measured from the nearest rail, not from the

centerline of track.

4.B. Hwy Traffic Signal Interconnection

Check all that apply. If “Not Interconnected” is checked, do not check the other two

choices.

 “Not Interconnected” – crossings equipped with active warning systems that do

not have an electrical connection between the railroad active warning system and

the traffic signal controller assembly for the purpose of preemption.

 “For Traffic Signals” – crossings having an electrical connection between the

railroad active warning system and the traffic signal controller assembly for the

purpose of preemption.

 “For Warning Signs” – signs that are electrically connected to a railroad crossing

control circuit that is designed to illuminate the signs upon the approach or

presence of a train.

4.C. Hwy Traffic Signal Preemption

Check the appropriate box for the type of preemption. This field is not applicable if “Not

Interconnected” is chosen in field 4.B. and should be left blank.

Preemption is defined in the MUTCD as the transfer of the normal operation of highway

traffic signals to a special control mode.

In this instance preemption occurs as a result of a signal received from the railroad

active warning device system
