Trolleybuses

Trolleybuses

A trolleybus is essentially an electrically powered bus that is attached to and draws power from overhead lines. The trolleybus can be seen as a branch of, and a parallel development to, the conventional bus, and is exclusively used for public transport (apart from some systems recreated in transport museums). Trolleybuses appeared at nearly the same time as combustion engine powered buses, with a system in Dresden, Germany, in 5 May 1901. As with conventional buses, double-deck and articulated versions of the trolleybus have been developed.
