Metre gauge is the system of medium gauge railways and tramways with a track gauge of 1,000 mm (3 ft 3 3⁄8 in). In some African, American and Asian countries it is the main gauge. In Europe it has been used for local railways in France, Germany, and Belgium, most of which were closed down in mid 20th century. Only in Switzerland and northern Spain do huge metre gauge networks remain in continuous use. Also, many European urban trams run on metre gauge. With the revival of urban rail transport, in some cities metre gauge light metros were established, while in other cities metre gauge was replaced by standard gauge.
