DCC and Overhead Trolley Wire Operation
WEBFor every car with two trolley poles, we wire for "trolley pole" reverse. This allows cars to be reversed with just changing the poles and not changing the polarity of the layout. In trolley pole reverse, both brushes of the motor are wired to the two trolley poles and the trolley pole hooks supply the necessary connection to ground.

WEBIn contrast, trolley poles clamp around overhead wires, ensuring they maintain contact with the wire (and therefore remain powered) by harnessing the wire within a socket at the top of the pole. The socket on the top of the pole has a bottom and two sides, and is raised to clamp around the wire and slide along it as the streetcar travels:

WEBNov 22, 2017 · To this end most designers adopt simple trolley wire, with or without automatic tensioning. It is desirable that the contact wire should be as level as possible, without ‘hard spots’, so that wear of both wire and pantographs is minimised. Hard spots can result in pantograph bounce, and arcing.
