The Berninabahn links St. Moritz with Tirano, just across the border in Italy and has a character of its own. It retains the original 1000V DC power supply and climbs on gradients as steep as 1 in 14 to a summit 2253m above sea level, the highest crossing of the Alps by a conventional adhesion only railway.
The line remains open throughout the winter, when the snow can be above roof height at the summit.
