The Bernina Express is an express train which connects Chur (or Davos) to Poschiavo and Tirano crossing the Swiss Alps from north to south. The train is operated by the Rhaetian Railway, it is not an "express" in the sense of being a high-speed train but rather in the sense that it provides a one-seat ride for a long duration travel.
The trip on the Bernina Express is a 4 hour railway journey across 196 bridges, through 55 tunnels and across the Bernina Pass on the highest point at 2,253 metres in altitude. The entire line is metre gauge
The Bernina Railway built the line from 1908-1910 and operated independently until the 1940s. The Bernina Express uses gradients of 7% to achieve a difference in height of about 1800 meters from the summit at Ospizio Bernina to Tirano.
The Albula line and Bernina line on the Bernina Express route were declared a World Heritage Site in 2008.
Alp Grüm (2,091 m) is the first station south of the Alps, situated above the Lago Palü and right below the Piz Palü and its glacier. After many hairpin turns the train reaches Cavaglia (1,693 m) above the Val Poschiavo and finally, the Swiss Italian speaking town of Poschiavo at 1,014 meters. The train then follows the course of the Poschiavino and passes at Le Prese (964 m) and Miralago (965 m) both on the Lake Poschiavo's shore. After Miralago it continues its descent toward Brusio (780 m), where it passes the spiral of the Brusio Viaduct. Shortly after having passed the Italian border at Campocologno (553 m) the Bernina Express ends its journey at the Tirano station at 430 meters.
