Restart Tunnel - Germany/Switzerland

The incredible £598m tunnel stretching 4270m boosting transport between 2 pretty countries

The project suffered a set back in 2017 after a collapse, but is now back on track.

Civil works on a massive railway project in Europe have been completed, officials have announced. The 4,270-metre-long twin-bore Rastatt Tunnel is a major part of a scheme to ensure the section of a key Rhine Valley main line between Karlsruhe and Basel in Switzerland is extended to four tracks. Tunnelling, done using two tunnel boring machines (TBMs), has now finished, and final railway systems work is now underway.

The final part of the slab track, replacing the traditional elastic combination of sleepers and ballast, overhead electrification equipment, signalling, lighting and communications systems need to be installed. DB said it is working to ensure that the first trains are able to travel through the tunnel as planned by the end of 2026. The project is a key part of the around 200-kilometre upgraded line between Karlsruhe and Basel - one of the oldest rail lines in Germany.
