Metre gauge is used in around 95,000 kilometres (59,000mi) of tracks around the world.[citation needed] It was used by several European colonial powers including France, Britain and Germany in their colonies. 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 1,009mm (3ft3+23⁄32in) gauge is used in Sofia, Bulgaria. Another similar gauge is 3ft6in (1,067mm).
See Metre gauge railways in Denmark[broken anchor] and Narrow-gauge railways in Denmark. A few local railways. Only one remains, but regauged to standard gauge.
The Piraeus, Athens and Peloponnese Railways used to be the largest metre-gauge network in Europe but are now largely abandoned. Only the suburban rail service of Patras, and the Olympia–Katakolo tourist railway still use the network. An undergoing project of Messinian Suburban Railway will bring back at least 40 kilometers of the unused metre gauge railway
Several mainly mountainous branch lines, mostly abandoned in the 1990s, never fully interconnected — connected to the REFER network by means of shared stations and some dual-gauge stretches. Metro de Mirandela and Vouga line remain in use. Other metric networks include Funchal rack railway (defunct in 1943), Coimbra trams (defunct in 1980), and Sintra trams.
Sierra Lumber Company Railroad. A meter-gauge railway built in 1881 from Lyonsville, California into the redwood forests. It used three steam locomotives and worked until 1907.[5]
