UNESCO RHB Bernina Express Enjoy riding the most famous train in the Alps on board the Rhaetian Railway panorama coach whose north alpine route is a 145-km stretch that cuts through Graubünden, boasting the most beautiful railway routes in the world. During the trip over the Bernina pass, the train reaches an altitude of 2.253 m (7.390 ft) and masters gradients of 70%. The Bernina Express runs without cogwheels, on the highest long-distance railway transversal in the Alps over up to more then 200-metre long and 90-metre high bridges, through winding tunnels, past raging mountain torrents, glaciers and a rich array of alpine flowers to southerly Valposchiavo, over the spiralling viaduct at Brusio and on to Tirano in Italy where our van will be waiting for you.
