Milestone for hard Rock Tunnelling: Final double Breakthrough Follo Line in Norway

 

The construction of Norway's longest railway tunnel marked a breakthrough for the use of tunnel boring machines in hard rock tunnelling. In Scandinavia long rail tunnels have hitherto been drilled and blasted rather than bored. In the Follo Line Project, the tunnel boring machines made a convincing case for themselves all the way through the extremely hard Norwegian rock. Four tunnel boring machines (TBMs) by Herrenknecht worked simultaneously to excavate the main part of two 20-kilometer railway tunnels between Oslo and Ski. On February 26, 2019, the final double breakthrough of the Double Shield TBMs "Anna" and "Magda" successfully completed the challenging mission and drew a spectacular close.
