Editing Overhead line (section)

=== Australia ===
Many cities had trams and trolleybuses using trolley poles. They used insulated crossovers, which required tram drivers to put the controller into neutral and coast through. Trolleybus drivers had to either lift off the accelerator or switch to auxiliary power.

In [[Melbourne]], Victoria, tram drivers put the controller into neutral and coast through section insulators, indicated by insulator markings between the rails.

Melbourne has several remaining [[level crossing]]s between electrified suburban railways and tram lines. They have mechanical switching arrangements (changeover switch) to switch the 1500 V DC overhead of the railway and the 650 V DC of the trams, called a Tram Square.<ref>[https://web.archive.org/web/20071208021201/http://www.tmsv.org.au/papers/lvlcross.htm TMSV: Tramway level crossings in Victoria]</ref> Several such crossings have been grade separated in recent years as part of the [[Level Crossing Removal Project]].
