Recommended Instructions for Inspection and Test of Highway-Rail Grade Crossing Warning System Installation Before Placing in Service
Revised 2006 (3 Pages)
A. Purpose
This Manual Part recommends instructions that apply to the inspection and testing of highway-rail grade crossing warning devices and system installations or modifications before placing in service. They set forth general requirements representing recommended practices.
B. General
Check and test to ensure that:
1. Plans are legible and correct, and kept at all locations.
2. Stand-by source(s) of power is provided as designed and functions as
intended.
3. For each highway approach, signals are properly aligned and view of
signals is not obstructed.
4. Voltage at each light unit is as instructed.
5. Where manual cut-out and starting buttons are used, they function for
each track as intended.
6. Time of time element relays or any solid state device which performs the
same function, where used in starting circuits, is not less than time shown
on approved plans.
7. Warning devices function as intended.
8. Control systems, including highway traffic signal pre-emption
interconnection, if applicable, function as intended.
9. On primary batteries after continuous load for 5 minutes, or after a shunt
of 0.5 ohm has been applied for 5 minutes, voltage measures normal.
10. Proper signs are installed, clean and clearly visible to approaching traffic

arrival of any normal train movement through the crossing.
5. Gate arms fully rise in not more than 12 sec., or as instructed.

without rebound or slap, and are securely held when in the raised position.
9. Buffing or snubbing of gate mechanism is effective, per manufacturer's
