Bever–Scuol-Tarasp railway
The Bever–Scuol-Tarasp railway is a Swiss metre-gauge line, operated by the Rhaetian Railway and connecting the Lower Engadine with the Albula Railway. The 49.4 km (30.7 mi) single track line has a total of 17 tunnels and 55 major bridges, and was opened in 1913. The route is electrified, having been used as a test track for single-phase alternating current from the date of its construction.
