The museum is based in the large railway station in the village of Bergün. The Albula narrow-gauge line is part of the Rhaetian Railway (RhB) and is a World Heritage site. It was completed in 1903/4 after just five years despite its challenging route of 62km from Thusis across the Albula Pass to St Moritz. It required a climb of over 1km, 137 bridges and 42 tunnels. It was built at a gauge of 1,000mm with steam locomotives but it was electrified in 1919. The museum, which opened in 2012, tells the story of the construction of the railway using maps, plans, photographs, films and artifacts. There are also multimedia displays to demonstrate tunnelling methods and wooden blocks with which to build a viaduct. Visitors can enter the cab of an electric locomotive outside the building as a simulator. Inside, a working model railway shows the railway as it was around 1960.
