The 2 wires don't touch (Even though the bow collector or pantograph is briefly in contact with the two wires).

Electric powered trains that gather their current from overhead traces use a device for instance a pantograph, bow collector or trolley pole. It presses from the underside of the bottom overhead wire, the Make contact with wire. Recent collectors are electrically conductive and allow recent to movement by way of into the practice or tram and back to your feeder station with the steel wheels on 1 or both jogging rails.
