Dual-mode bus

（重定向自Dual Mode Bus）

Boston Neoplan AN460LF dual-mode trolleybus, operating in diesel mode (with its trolley poles lowered)

The Downtown Seattle Transit Tunnel was served exclusively by dual-mode buses from its opening in 1990 until the early 2000s.

A dual-mode bus is a bus that can run independently on power from two different sources, typically electricity from overhead lines (in the same way as trolleybuses) or batteries, alternated with conventional fossil fuel (generally diesel fuel).

In contrast to other hybrid buses, dual-mode buses can run forever exclusively on their electric power source (wires). Several of the examples listed below involve the use of dual-mode buses to travel through a tunnel on electric overhead power.
