Lötschberg Tunnel



The Lötschberg Tunnel is a 14.612 km long railway tunnel on the Lötschberg Line, which connects Spiez and Brig at the northern end of the Simplon Tunnel cutting through the Bernese Alps of Switzerland. Its ends are at the towns of Kandersteg (2 km away) in the canton of Bern and Goppenstein in the canton of Valais. The top elevation of the tunnel is 1240 m above sea level, this is the highest point of the main Swiss railway network.

Construction began in 1907 and suffered delays by several severe accidents.
 * February 1908: An avalanche destroyed a hotel that the workers lived in, killing 13.
 * July 1908: The tunnel broke into a deep fissure below the Gasterntal valley and flooded with water and glacial deposit from the fissure, killing 25, and 1554 meters (5100 feet, 0.9656 mile) of the tunnel had to be abandoned and sealed off and replaced by a curved bypass.
 * March 1911: Breakthrough was achieved
 * 3 June 1913: Finalization
 * 15 July 1913: Regular service through the Lötschberg Tunnel began in 1913.

The tunnel is a single bore twin track.

The BLS AG company offers a car transport service through the tunnel, between Kandersteg station and Goppenstein station, for accompanied vehicles. The journey time of approximately 20 minutes, passengers remain in their cars in open sided car transport vehicles. At peak times, the car transport service operates in each direction every 7½ minutes.

The new Lötschberg Base Tunnel, opened on June 15, 2007, has been constructed some 400 m below the level of the current Lötschberg Tunnel as part of the NRLA (New Railway Link through the Alps) project.
