ABSTRACT:
An electronic controller for a highway-railroad grade crossing warning system is coupled to an approach circuit and to an island circuit and activates a warning device when a train is present in either of the approach or the island circuits. The controller has a display with touch-sensitive fields for selectively taking the approach circuit or island circuit out of service. Additional touch-sensitive fields on the display may be used for selecting the amount of time that the approach or island circuits remain out of service and for confirming that the maintainer wishes to take the these circuits out of service. Service is automatically restored upon expiration of the selected amount of time.
