The overhead construction consists of four No. 0000 grooved copper trolley wires which are suspended in pairsfrom yoke hangers. Span wire construction using orna-mental iron poles at the curb line is employed in Bradford,but in Leeds the trolley wires are carried by bracket arms18 ft. long. The two positive wires carry current at525 volts and they are sectionalized at distances of about Yz mile. The negative wires are not sectionalized andwherever possible they are bonded to the rails of inter-secting or parallel tramway lines so as to decrease thedrop in the return circuit. The trolleys on the cars are of the double under-running.
