Rigi Railways (German: Rigi Bahnen) is a railway company that operates a group of railways on the mountain Rigi, located between two of the arms of Lake Lucerne, in Switzerland. They include two standard gauge rack railways, the Vitznau–Rigi Bahn (VRB) and the Arth–Rigi Bahn (ARB), along with the Luftseilbahn Weggis–Rigi Kaltbad (LWRK) cable car.
Reaching a height of 1,752 metres (5,748 ft) above sea level, the Rigi Railways are the highest standard gauge railway in Europe. They are also the highest railway in both cantons of Lucerne and Schwyz. The Vitznau–Rigi Bahn is also notable as the first mountain rack railway in Europe, and even the second in the world, after the Mount Washington Cog Railway in the United States.
