A trolleybus is an electric bus that draws power from dual overhead wires using spring-loaded 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. 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, but there are exceptions.
Transport in Argentina is mainly based on a complex network of routes, crossed by relatively inexpensive long-distance buses and by cargo trucks. The country also has a number of national and international airports. The importance of the long-distance train is minor today, though in the past it was widely used and is now regaining momentum after the re-nationalisation of the country's commuter and freight networks. Fluvial transport is mostly used for cargo.
