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 Jungfrau Railway terminates at the highest station in Europe.
Also, nearly all street tramways in Switzerland have always been meter gauge.
Since December 2022, 1,435 mm (4 ft 8+1⁄2 in)/1,000 mm (3 ft 3+3⁄8 in) gauge changing trains have started operating between Lake Geneva and Interlaken.
