Loetschberg Tunnel Opens: 34.6 Kilometres Through the Alps

Published on 15.09.2009

BG Consulting Engineers has managed the design and construction of one of the world’s longest tunnels.

The Loetschberg base railway tunnel opened on December 6, 2007, and has considerably increased transit capacity on the north-south international route. This key segment of the European corridor stretching from Rotterdam to Genoa links the Cantons of Berne and Valais. Passing under the Swiss Alps, it allows trains to operate at a speed of 250 km/h and reduces travel time through the Alps by 20-30%.
BG’s involvement in the project began in the early 1990s. The company participated in all the design and construction phases of this extraordinary project. Innovative solutions and techniques were used for both the civil works and the electromechanical facilities.
