Albulabahn trail panel
Panel seen on the rail history nature trail between Preda and Bergün. In order to overcome the height difference of 417 m (1,368 ft) between Bergün and Preda – in only 6.5 km (4.0 mi) as the crow flies – without requiring excessive slopes or radii, the route is extended by 12 km (7.5 mi) by various engineering structures (including three spiral tunnels, two curved tunnels and four valley crossing viaducts).
