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.
