During the construction of the Leipzig City Tunnel in the shopping centre under the station concourse of Leipzig Main station it was not possible to carry out any works from above ground. Therefore, two pilot tunnels were driven by pipe jacking so that vertical freezing bulkheads could be built.
1,700 m above sea level: In the Linthal Project 2015 the inclined tunnel with an incline of 24 % compensates an altitude difference of 900 m in the high mountains of Switzerland.
