History


Schwabstraße station was built in the course of the construction of the Stuttgart S-Bahn in the mid-1970s. The station was built using excavation from the surface and mining techniques for the terminal loop. Its construction proved to be very difficult. The shell was completed in December 1977 and in 1978 the first section of the Connection line began operating to Schwabstraße. In 1985, line was extended to the southwest to Stuttgart Universität station at the University of Stuttgart

. Access routes to the platform are at either end of the platform. At the western end of the platform the tracks to the turning loop separate from the through tracks towards Universität.

Terminal loop

The station has an unusual operational feature, a turning loop. It runs completely underground and contains a siding for a full train. The depth of the ground covering the tunnel ranges from 17 m near the platforms to 80 m at its at its western end near the former Stuttgart West station. Given the number of trains using the line, a return loop was found to have a higher economic return than simple terminating tracks despite the higher construction costs.

Excavation of the loop began on 7 October 1974 and the construction of the junction structures and the first 60 m sections of the two single-track tunnel tubes of the Hasenberg Tunnels towards the Gäu Railway (Gäubahn). The actual connection to the Gäu Railway was built in 1979 and went into operation in 1985.

The front of the terminal loop is in leached Gipskeuper

, which swell strongly when in contact with water, which is inevitable in a tunnel, and create strong forces on the sides of the tunnel. Accordingly, the inner shell of the tunnel is up to 1 m thick.

The tunnel section has an inner diameter of 6.70 m on single-track sections and 9.80 m on two-track sections. The radius of the loop is 190 m and its length is 1,500 m.
