When a trolley bus reaches a road junction, wire-switches, installed on the overhead conductor cables, control its direction of travel. Switches may be in the default “straight-through” position or in “turnout” position. As a bus passes a switch in turnout position, a sensor mounted on the overhead cables detects the presence of the current collector. The control system then resets the switch to the default position.
