This is the length of the Brenner Base Tunnel and the Innsbruck bypass with which it links south of Aldrans. This will make it the longest underground railway connection in the world.
The construction work and the railway outfitting of the Brenner Base Tunnel should be completed by 2026. After that, there will be a year of test operations. The tunnel will become fully operational in December of 2027.
Passenger trains will travel through the tunnel at a top speed of 250 km/h.
Water quality is monitored at 1,350 measuring stations all along the project area.
The trip from Innsbruck to Fortezza takes 80 minutes today. The trip through the BBT will take only 25 minutes.
