The electrical supply system track is designed for vehicles (17) fitted with rubbing friction contacts (16,22) arranged along a preferably centered longitudinal axis. The track is divided into electrically isolated segments (5A,5B,5C) and are arranged to cover a trench formed in the roadway along which the vehicles travel. The system uses individual static type switches (11) for connection of each segment . These switches ensure electrical continuity with a return line (14). The switches (11) for individual segments and the supply and return connection (13,14) are contained inside the trench. The switches (11) for each segment are controlled by individual controllers (12) which uses a coded connection signal, designed to actuate connection of, in sequence, those segments immediately near to the succession of conducting tracks or in the case of track end connection of the last segment. The vehicles include means for transmitting a coded control signal to a track segment.
