Switzerland has an extensive collection of narrow-gauge railways, almost all of which are metre gauge and electrified with different voltages. Most lines have at least one interchange station with the standard gauge Swiss Federal RailwaysorBern–Lötschberg–Simplon railway.
The cantons listed below are the principal areas of operation, but some lines may extend into parts of neighbouring cantons and countries:
There are trams operating on nine systems in seven Swiss cities. Street-running tramways are nearly all 1,000 mm (3 ft 3+3⁄8 in). The Chemin de fer Bex–Villars–Bretaye (BVB) in Bex is more of a mixed interuban light rail line connected to a rack railway but it does have some street running portions, particularly in Bex where the BVB operates along the right of way of a tramway system originally built in the 1890s.
