[1] Metre gauge is used in around 95,000 kilometres (59,000 mi) of tracks around the world.
In Europe, large metre-gauge networks remain in use in Switzerland, Spain and many European towns with urban trams, but most metre-gauge local railways in France, Germany and Belgium closed down in the mid-20th century, although some still remain.
With the revival of urban rail transport, metre-gauge light metros were built in some cities.
The slightly-wider 1,009 mm (3 ft 3+23⁄32 in) gauge is used in Sofia, Bulgaria.
