Brenner base tunnel

Project description:

The tunnel is the centerpiece of the railway axis Verona -Munich and consists of two single-track tubes that run at a distance of 40-70 m and are connected with cross passages at intervals of 333 m. The tunnel is located in the middle of the railway axis Verona -Munich. In addition, a continuous exploratory tunnel will be constructed in the middle between the two main tunnel tubes. The BBT will have a total length of 64 km, making it the longest underground railway link in the world. In Innsbruck, the BBT will lead into the existing railway bypass. The new two-tube tunnel that is going to be built between Innsbruck and Franzensfeste will be 55 km long.
