Abstract
A track for a suspended combined electric current collection and traction system including a base (22) and a resilient shield (26, 28) together defining an elongate space divided into two halves by a resilient beam (32), each of which contains a conductor (33). Spaced contact members in the form of bars (34) forming a rack on each side of the track or two rows of Z shaped contacts (82) extend through the shield and are normally spaced from the conductors. Embedded in the base are two parallel flexible metallic cables (40; 70) connected together by connectors (42; 74) by which the track may be suspended. In use, the reaction wheels (60) of a locomotive engage the tops of the cables (40; 70) thus drawing a current pick-up member (52; 86) into contact with the contact segments pressing them against the conductors (33) to pass electric current to an electric motor. A drive member which may be constituted by current pick-up pinions (52) engaging the racks or a drive wheel (88) engaging the shield between the Z shaped contacts (82) propels the locomotive along the track.
