The conveyor safety circuit (40) is connected on remotely operated vehicles (12) each having on-board controllers (28) which automatically run along guide rails (18) powered from power rails (20) extending along the guide rails (18). The safety circuit (40) interrupts power to the on-board controllers (28) when neutral is lost or during power down. The safety circuit (40) will provide power to the vehicle (12) during brief interruptions of power or neutral, i.e., brush skips, without vehicle (12) shut down.
