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. BLS upgrades the Tunnel. This will put in place the prerequisites for a half-hourly Intercity service between Bern and Valais. And freight trains will therefore travel more frequently through the Base Tunnel instead of using the Lötschberg mountain line, thus increasing productivity.

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.
