The following excerpt shows some major tunnelling projects which were running in Germany during 2011:
- 19 km of double track high speed railway lines (250 to 300 km/h): between Karlsruhe and Basel; partly upgraded and partly replaced, integrating two major bored tunnel projects of 9 and 6 km respectively in length. Each tunnel consists of two parallel single tubes with about 10.5 m excavation diameter. Inauguration is planned for 2012 to improve the traffic connections between Northern and Southern Europe via Lötschberg and Gotthard base tunnels in Switzerland.
- 32 km double track tunnels on the new/upgraded high-speed line between Nuremberg and Erfurt and 31 km between Erfurt and Halle/Leipzig. These tunnels – like the majority of the tunnels for the DB high-speed routes – are mainly built by conventional means.
General details on tunnelling in Germany can be seen in the table below according to the latest statistics conducted by STUVA.
