"Lilia" - The first tunnel boring machine for the construction of the Brenner Base Tunnel is ready for takeoff
The tunnel boring machine, named "Lilia", in the design of a single shield hard rock TVM with segment lining, has impressive key data: it has a boring head diameter of 10.37 meters, a total length of around 160 meters and a total weight of 1,900 tons - including the trailing structure.
Now, after successful factory acceptance, "Lilia" is being expertly dismantled into its individual parts for the first time and transported to the assembly cavern in the Ahrental, south of Innsbruck. In the new year, towards the end of January, assembly will begin on site. Then "Lilia" will be ready for takeoff - and in spring 2023 will start its approximately 8.1-kilometer drive in the main tunnel east toward the south.
