A dual-mode vehicle is a vehicle that can run on conventional road surfaces or a dedicated track known as a "guideway". Dual-mode vehicles are commonly electrically powered and run in dual-mode for power too, using batteries for short distance and low speeds, and track-fed power for longer distances and higher speeds. Dual-mode vehicles were originally studied as a way to make electric cars suitable for inter-city travel without the need for a separate engine. More recently, starting in the 1990s, a number of dual-mode mass transit systems have appeared, most notably a number of rubber tyred trams and guided buses.
