Track gauge in Switzerland
Switzerland has an extensive network of 1,000 mm (3 ft 3+3⁄8 in) metre gauge railways, many of which interchange traffic (most prominent is the Rhaetian Railway). They are concentrated in the more heavily mountainous areas. The Jungfraubahn terminates at the highest station in Europe. Dual gauge (combined metre- and standard gauge trackway) also exists in many areas. Also, nearly all street tramways in Switzerland have always been metre gauge.
