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 ...
This is a list of trolleybus systems in the United States by state. It includes all trolleybus systems, past and present. About 65 [ 1 ] : 78 trolleybus systems have existed in the U.S. at one time or another.
Richmond Theatrical District in 1923, with Perley Thomas streetcars. An industrial rail siding alongside Stockton Street between 4th and 5th Streets. The Richmond Union Passenger Railway, in Richmond, Virginia, was the first practical electric trolley (tram) system, and set the pattern for most subsequent electric trolley systems around the world.
The Toronto Transit Commission maintains the most extensive system in the Americas (in terms of total track length, number of cars, and ridership).. Streetcars or trolley(car)s (American English for the European word tram) were once the chief mode of public transit in hundreds of North American cities and towns.
Three types of electric road systems. An electric bus (black) receives power from the road: (A) with three inductive pickups (red) from a strip of resonant inductive coils (blue) embedded several centimeters under the road (gray); (B) with a current collector (red) sliding over a ground-level power supply rail segment (blue) flush with the surface of the road (gray); (C) with an overhead ...
Articulated electric trolleybuses can be difficult to control, with their motors producing momentary peak power in excess of 600 kilowatts (816 PS; 805 hp). The trailer section of a "puller" bus can be subject to unusual centripetal forces , which many people can find uncomfortable, although this is not an issue with "pushers".
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).
A battery electric bus is an electric bus that is driven by an electric motor and obtains energy from on-board batteries. Many trolleybuses use batteries as an auxiliary or emergency power source. Battery electric buses offer the potential for zero-emissions, in addition to much quieter operation and better acceleration compared to traditional ...
