Abstract:
A system for selectively disabling highway crossing equipment includes a timer for controlling a maximum out of service time for the highway crossing equipment, a switch for controlling disablement of the highway crossing equipment, and control circuitry responsive to the timer and the switch. The control circuitry disables the highway crossing equipment in response to an input received from the switch before the maximum out of service time has been reached and re-enables the highway crossing equipment in response to a subsequent input from the switch received before the maximum out of service time has been reached. The control circuitry places the highway crossing equipment in a failsafe condition when the maximum out of service time has been reached without receiving the subsequent input from the switch.
