A trolleybus is an electric bus that draws power from dual overhead wires using spring-loaded trolley poles. Two wires, and two trolley poles, are required to complete the electrical circuit. This differs from a tram or streetcar, which normally uses the track as the return path, needing only one wire and one pole. They are also distinct from other kinds of electric buses, which usually rely on batteries. Power is most commonly supplied as 600-volt direct current, but there are exceptions.
Heritage streetcars or heritage trams are a part of the efforts to preserve rail transit heritage. In addition to preserving street-running rail vehicles, heritage streetcar operations can include upkeep of historic rail infrastructure. Working heritage streetcars are closely related to the growing global heritage railway movement and form a part of the living history of rail transport.
