German Rail is building a new, underground Central Train Station and corresponding access tunnels in Stuttgart, the capital of Baden-Württemberg.
The Ober- and Untertürkheim tunnels, excavated by conventional mining method, will underpass the river Neckar. The geotechnical conditions include claystone subjected to swelling and sediments under the Neckar River. In addition cross passages will be built between the parallel tunnels bores at regular intervals.
