Busscar in the context of Trolleybus
A trolleybus (also known as trolley bus, trolley coach, trackless trolley, trackless tram (in the 1910s and 1920s), road tram or simply trolley) is an electric bus that draws power from dual overhead lines (generally suspended from roadside posts) using spring-loaded or pneumatically raised trolley poles. Two wires, and two trolley poles, are required to complete the electrical circuit. This differs from a tram or streetcar, which normally uses the track as the return path, needing only one wire and one pole (or pantograph). They are also distinct from other kinds of electric buses, which usually rely on batteries. Power is most commonly supplied as 600-volt direct current in older systems and 750-volts in newer systems, but there are exceptions.
Currently, around 300 trolleybus systems are in operation, in cities and towns in 43 countries. Altogether, more than 800 trolleybus systems have existed, but not more than about 400 concurrently.
