Cover Story: Work to upgrade the Westbahn line to a modern high-speed line has been under way since the 1980s. Because of the route and the topographical conditions, a number of tunnels are required. The requirements for rail tunnels have changed significantly since the start of tunnel construction for the upgrading of the Westbahn line, while mechanised tunnelling has made great progress. The article on side 347 explains the procedure used by the client for the selection of a method of tunnelling.
