Showing how tramway electrical current was returned to the electrical sub-station via the rails.Demonstrates an earth return bonding piece.Traction Return Current Rail Bond, consists of a multi strand copper cable abt 19mm dia. and 530mm long, with block of steel (25x25x43mm) brazed onto each end. The block of steel gets welded to the outside of the rail head at or near a joint in the rails. The bond is to ensure a reliable return current as the fishplates and bolts are subject to dirt and rust which can inhibit the current.tramways, electrical engineering, earth return, bonds, trackworks
