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 ...
Busscar trolleybus in São Paulo, Brazil Solaris trolleybus in Landskrona, Sweden Video of a trolleybus in Ghent, Belgium. 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 ...
Trolleybuses use a second parallel overhead line for the return, and two trolley poles, one contacting each overhead wire. (Pantographs are generally incompatible with parallel overhead lines.) The circuit is completed by using both wires. Parallel overhead wires are also used on the rare railways with three-phase AC railway electrification.
Trolleybus route 13 was featured in the 2023 Chinese television series Blossoms Shanghai, in which Xue Zhi , who was the first love of main character A Bao , was a fare inspector on the route. [ 2 ] [ 6 ] According to a Weibo post by Shanghai Morning Post , several buses on the real-life route 13 are expected to feature an advertisement ...
Boston Neoplan DMA-460LF dual-mode trolleybus, operating in diesel mode (with its trolley poles lowered). 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).
The first trolleybus line was opened by the former Market Street Railway Company (MSR). The San Francisco Municipal Railway ("Muni") opened the second trolleybus line on 7 September 1941. MSR was absorbed by Muni on 29 September 1944. Most of the current trolleybus system was built to replace MSR tramway lines.
A trolleytruck (also known as a freight trolley or trolley truck [1]) is a trolleybus-like vehicle used for carrying cargo instead of passengers. A trolleytruck is usually a type of electric truck powered by two overhead wires , from which it draws electricity using two trolley poles .
Recent improvements in trolleybus design include the automatic connection and disconnection of power poles either by the driver or in the event of mechanical dis-engagement from the overhead wires, so that the driver can remain in control, using on-board battery power.
