Brienzer Rothorn 🚂 (Bern, Switzerland)

The Brienz Rothorn Railway is a tourist rack railway in Switzerland, which climbs from Brienz, at the eastern end of Lake Brienz, to the summit of the Brienzer Rothorn. The railway is 7.6 kilometres (4.7 mi) long, is built to 800 mm gauge (2 ft 7+1⁄2 in gauge), and uses the Abt double lamella rack system.

The railway was opened on 17 June 1892, after a two years construction period.

Unusually for Switzerland, the line is not electrified, and most trains are operated by steam locomotives.

The Brienz Rothorn Railway reaches a height of 2,244 metres (7,362 ft) above sea level and is the fourth-highest railway in Switzerland.
