description Brenner Base Tunnel Overview
The Brenner Base Tunnel is a cross-border railway project running beneath the Alps between the Innsbruck area in Austria and Fortezza in Italy. Its principal tunnel system is about 55 km long, while inclusion of the existing Innsbruck bypass creates a continuous underground rail route of roughly 64 km. Built primarily for mixed passenger and freight traffic, it is intended to provide a lower-gradient alternative to the historic Brenner railway. The project forms a central section of the Scandinavian-Mediterranean transport corridor.
help Brenner Base Tunnel FAQ
How long is the Brenner Base Tunnel?
The main Brenner Base Tunnel system will be approximately 55 kilometers long beneath the Alps. When combined with the existing Innsbruck bypass, it will create a continuous underground rail route of about 64 kilometers.
What is the primary purpose of building the Brenner Base Tunnel?
The tunnel is designed to significantly reduce travel times for both passenger and freight trains crossing the Alps between Austria and Italy. By bypassing the steep gradients of the current mountain pass route, it will massively increase rail transport efficiency and reduce carbon emissions.
Where do the northern and southern portals of the Brenner Base Tunnel connect?
The northern portal of the tunnel is located near the city of Innsbruck in Austria. The southern portal emerges near the town of Fortezza, located in the South Tyrol region of Italy.
How deep beneath the Alps does the Brenner Base Tunnel run?
Due to the extreme elevation of the Alpine mountains, the Brenner Base Tunnel reaches depths of up to 1,800 meters beneath the surface. This extreme depth necessitates complex ventilation systems and underground rescue stations to ensure passenger safety.
