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 ...
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 ...
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 ...
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).
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".
The distinction between a solar-only electric bus and an electro-solar bus is fluid, as the distinction depends on the actual usage: whether the bus is recharged from solar or other power sources. Solar-only bus services involve recharging the bus from solar energy, usually from solar panel-covered bus station canopies .
Bus rapid transit (BRT), also referred to as a busway or transitway, is a trolleybus, electric bus and public transport bus service system designed to have much more capacity, reliability, and other quality features than a conventional bus system. [3]
