Current Collection System

Assembly

Because the running tires are insulating, traction power at 750 V DC is drawn through sliding shoes that bear against lateral power bars mounted alongside the guide bars; the steel running rails serve as the return path. A full specification article for this item is being written. Meanwhile its bill of materials and connections are below.
