However, on most railway vehicles using overhead wire, the trolley pole has given way to the bow collector or, later, the pantograph, a folding metal device that presses a wide contact pan against the overhead wire. While more complex than the trolley pole, the pantograph has the advantage of being almost free from dewiring, being more stable ...

A trolleybus (also known as trolley bus, trolley coach, trackless trolley, trackless tram – in the 1910s and 1920s [1] – or trolley [2] [3]) is an electric bus that draws power from dual overhead wires (generally suspended from roadside posts) using spring-loaded ...

MSR was absorbed by Muni on 29 September 1944. Most of the current trolleybus system was built to replace MSR tramway lines.

A dual-mode bus is a bus that can run independently on power from two different sources, typically electricity from overhead lines like a trolleybus or from batteries like a hybrid bus, alternated with conventional fossil fuel (generally diesel fuel).
Trolley pole wheel on top of the trolley pole of Twin City Rapid Transit Company No. 1300. A current collector (often called a "pickup") is a device used in trolleybuses, trams, electric locomotives and EMUs to carry electric power from overhead lines, electric third rails, or ground-level power supplies to the electrical equipment of the vehicles.
The city's aging trolleybuses were spiffed up, and the overhead wire expanded in 1962 to serve the World's Fair, but citywide the Seattle Transit System was increasingly abandoning the trolley routes. One year later in 1963, the commission retired 175 trolleybuses and tore down the overhead wire in the north end of the city and West Seattle. A ...
