Brenner Base Tunnel - Mules 2-3 Lot
The Mules 2-3 Lot project refers to the construction of the main section of the Italian side of the Brenner Base Tunnel, the joint Italian-Austrian project to build a railway tunnel that will connect Italy to Austria.
The work is part of the project to upgrade the Munich-Verona railway line. Once completed, it will be the longest underground railway link in the world.
The Mules 2-3 Lot involves the construction of approximately 65 kilometers of tunnels, of which 42.5 km with mechanized excavation method and 22 km using traditional method. Three TBMs, Virginia, Serena, and Flavia, have been used for the mechanized excavation. The works include the excavation of 39.8 km of mainline tunnels and 14.8 km of exploratory tunnel, the emergency stop at Trens with the corresponding access tunnel, and the cross tunnels, which will connect the main tunnels every 333 meters.
