VIEW OF CAR HOISTED TO RECEIVE NEW WHEELS Aluminum Catenary Construction IN THE usual catenary construction, the contactsystem is not depended on for power wires were formerly used for this service, butwhere traffic is heavy they have been largely replacedby bronze or steel wires. These wear better, but havepoorer conductivity. The necessary conductivity in thecatenary system has been obtained on the Lake ErieNorthern Railway, as explained in the January issue ofthe Electric Journal, by wrapping the conductoraround the steel
