Abstract: This system for powering an overhead contact line, which includes a contact wire consisting of a plurality of conductive sections separated by insulating sections, includes power supply sub-stations, each conductive section being connected, on the side of an upstream end, to an upstream sub-station via an upstream controlled switch and, on the side of a downstream end, to a downstream sub-station via a downstream controlled switch. This system includes a detection device, associated with a conductive section, to be monitored, which includes a means for transmitting a characteristic signal to an upstream or downstream end of said conductive section and a receiving means able to receive the characteristic signal at the other end, the receiving means modifying the value of a state signal applied to a control circuit for actuating the opening of the downstream switch and/or of the upstream switch.

Abstract: A guided ground vehicle that travels on a track having an electric contact rail for supplying electricity to the vehicle, the rail including several electrical circuits, each electrical circuit being connected to at least one electric switching member. The vehicle includes a device for managing a derailment of the ground vehicle and generating means for generating a control signal for controlling one of the electric switching members connected to the electrical circuits positioned across from the ground vehicle, to close that electrical circuit. The device includes detecting means for detecting the derailment of the ground vehicle and processing means connected to the detecting means and to the generating means. The processing means are adapted to deactivate the generating means to inhibit the generation of the control signal, in order to cause the opening of the circuits across from the vehicle.
