BLS is upgrading the Lötschberg Base Tunnel

The Lötschberg Base Tunnel is the centrepiece of the BLS infrastructure and a central element of the NRLA, the New Rail Link through the Alps. However, the Lötschberg Base Tunnel is also a bottleneck because two thirds of the tunnel can only be accessed via one rail tube. At the beginning of 2024, BLS got the green light to expand the full length of the tunnel to two tubes. This will finally complete the construction.

New track in the Lötschberg Summit Tunnel

Investing in the future: The tracks in the Lötschberg Summit Tunnel were last replaced in the 1970s. BLS is now investing in a modern and sustainable track so that our customers can continue to travel safely and conveniently through the tunnel between Goppenstein and Kandersteg.
