5 Improved power supply system for an overhead contact line This system (2) for powering an overhead contact line (4), which includes a contact wire (6) consisting of a plurality of conductive sections (10, 30, 50, 70) separated 10 by insulating sections (20, 40, 60), includes power supply sub-stations (120, 140, 160), each conductive section being connected, on the side of an upstream end, to an upstream sub-station via an upstream controlled switch (135, 155, 175) and, on the side of a downstream end, to a downstream sub-station via a downstream controlled switch (114, 134, 154). This system includes a detection device (230, 250), associated with a 15 conductive section (30, 50) to be monitored, which includes a means for transmitting a characteristic signal (S1, S2) 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 (S3, S4) applied to a control circuit for actuating the opening of the downstream switch and/or of the upstream switch.
