Lötschberg Tunnel

From Wikipedia, the free encyclopedia

The Lötschberg Tunnel is a 14.6 km long railway tunnel cutting through the Alps of Switzerland. Its ends are at the towns of Kandersteg in the Canton of Berne and Goppenstein in the Canton of Valais.

Construction began in 1906 and suffered delays by several severe accidents. In February 1908, an avalanche destroyed a hotel the workers lived in, killing 13. In July of the same year, a section of the tunnel collapsed, killing 25. The section was beyond repair, so a new tunnel had to be blasted, bypassing the site of the disaster. Breakthrough was achieved in March 1911. Regular service through the Lötschberg Tunnel began in 1913.

Currently, a Lötschberg Base Tunnel is being constructed some 400 m below the level of the current tunnel as part of the NEAT project.
