The most important railway line in Tyrol is the Brenner Line via the Brenner Pass. The Brenner Railway was opened in 1867 and runs from Innsbruck to Verona via the cities of Bolzano and Trento. Together with the Lower Inn Valley Railway in North Tyrol, this section of the route is part of the important European railway axis Berlin-Palermo, which connects northern Europe with southern Europe across the Alps. With the construction of the Brenner Base Tunnel and its completion in 2027, transit traffic on the rail will be promoted and relocated. After completion, the Brenner Base Tunnel, together with the Innsbruck bypass, will be the longest railway tunnel in the world at 64 km and will reduce the travel time between Bolzano and Innsbruck from 2 hours to 45 minutes.
