This is a list of mountain railways in operation in Switzerland. It includes railways that overcome steep gradients (over 5%) or whose culminating point is over 800 m (2,600 ft) above sea level. Most of them are located in the Alps, which include the highest European railways, both dead-end railways, such as the Jungfrau and Gornergrat, and railway crossings, such as the Bernina and Furka. Many of these railways converge on mountain railway hubs, notably Lucerne, Interlaken, Montreux, Aigle, Brig and Chur.
