Naming ceremony for Cannstatt long-distance railway tunnel
Cannstatt long-distance railway tunnel is part of the major Stuttgart 21 / new Wendlingen-Ulm railway line project, in which the railway hub in Stuttgart is being completely reorganized and the existing main station is to be replaced by a new underground station. A new high-speed railway line between Stuttgart and Ulm is being created.
Cannstatt long-distance railway tunnel is part of the major Stuttgart 21 / new Wendlingen-Ulm railway line project, in which the railway hub in Stuttgart is being completely reorganized and the existing main station is to be replaced by a new underground station. A new high-speed railway line between Stuttgart and Ulm is being created.
The ca. 3.507 m Cannstatt long-distance railway tunnel will connect the northern part of the new main station with Canstatt regional station and with the existing lines from there to Waiblingen and Ulm. The tunnel also forms part of the loop connecting the new main station with a holding and repair station at Untertürkheim which is also to be newly constructed.
From the eastern portal, the tunnel is being constructed as a two-track tube using mining methods. It is connected to a crossing structure which passes over a city railway tunnel and to a widening structure, both of which will be built using the cut-and-cover method.
The tunnel then continues as two single-track tubes constructed using mining methods, passing under the Feuerbach long-distance railway tunnel which is to be newly constructed, as well as a variety of railway facilities and structures. It also passes under buildings, in some cases with very little cover.
The single-track tubes were driven by means of a temporary access shaft which was constructed on the site of the former Nordbahnhof in an area where a connecting tunnel required for the escape and rescue concept is located.
The connection between the tunnel and the northern part of the new main station will be made by branch structures which are also being constructed using mining methods and via which the Feuerbach tunnel will also be connected. The tunnel is mainly being driven through various layers of gypsum keuper.
After the temporary access shaft had been completed and the first few meters of the connecting tunnel had been driven, the tunnel was officially named “Simone Tunnel” by tunnel patroness Simone Herrmann on 21st March 2014.
As part of a consortium, KREBS+KIEFER is responsible for plan management for the Stuttgart 21 project, and in connection with this, also provided the personnel authorized to submit building applications for the Cannstatt long-distance railway tunnel.
