Deutsche Bahn awarded a consortium comprising Strabag subsidiary, Züblin, and Max Bögl a EUR 500 million contract for the construction of the railway link between Stuttgart airport and the Stuttgart–Ulm railway line.
The contract covers a 5.3 km section of the new railway line alongside the A8 motorway and also includes the new long-distance and regional station beneath the Stuttgart airport and trade fair centre, its connection to the new railway line through the approximately 2.1 km airport tunnel, and the partial relocation of state road 1204.
This new project section also comprises a new connection between the new railway line and the airport curve, to be built at a later date to link the existing airport/trade fair station, including a new third track, to the Stuttgart–Hattingen railway line (Gäu Railway).
The underground airport/trade fair station will have a length of 400 metres and, like the two single-track 1.8 km long tubes of the airport tunnel, will be built by conventional tunnelling. The extensive earthworks and roadworks will be performed by Strabag.
Trains on the Gäubahn line from Stuttgart to Singen will serve the airport and trade fair, calling at the airport’s existing station. Current plans envisage that 50 long-distance and 62 regional trains will stop daily at the station.
