The Bernina railway line (German: Berninalinie; Italian: Linea del Bernina; Romansh: Lingia dal Bernina) is a single-track 1,000 mm (3 ft 3+3⁄8 in) metre gauge railway line forming part of the Rhaetian Railway (RhB). It links the spa resort of St. Moritz, in the canton of Graubünden, Switzerland, with the town of Tirano, in the Province of Sondrio, Italy, via the Bernina Pass. Reaching a height of 2,253 metres (7,392 ft) above sea level, it is the highest railway crossing in Europe and the third-highest railway in Switzerland. It also ranks as the highest adhesion railway of the continent, and—with inclines of up to 7%—as one of the steepest adhesion railways in the world. The elevation difference on the section between the Bernina Pass and Tirano is 1,824 m (5,984 ft), allowing passengers to view glaciers along the line.
On 7 July 2008, the Bernina line and the Albula railway line, which also forms part of the RhB, were recorded in the list of UNESCO World Heritage Sites, under the name Rhaetian Railway in the Albula / Bernina Landscapes. The whole site is a cross-border joint Swiss-Italian heritage area.
Trains operating on the Bernina line include the Bernina Express.
