Rhätische Bahn RhB AG

The Rhätische Bahn operates a network of approximately 384 km, connecting nearly every location in the Alpine canton of Graubünden. True connoisseurs can take the Bernina Express, a panoramic train that travels from Chur, the oldest city in Switzerland, to the southern town of Tirano (IT). The journey partially follows the UNESCO World Heritage route, crossing the Landwasser Viaduct, passing through spiral tunnels, and traversing the circular viaduct in Brusio.
