S-21 underground station (Stuttgart Main Station)

The Stuttgart 21 project involves redesigning the Stuttgart rail hub and converting the existing 16-track stub station into an eight-track lower-level through station, which will be rotated by about 90 degrees from its current orientation. The new main station will be connected by underground feeder lines from Feuerbach, Bad Cannstatt, ObertĂĽrkheim, UntertĂĽrkheim, and the Filder plateau. The storage sidings and maintenance facilities at the edge of Rosenstein Park will be relocated to the site of the current UntertĂĽrkheim freight yard.

The scope covers construction of the new long-distance rail tunnel and the station concourse, the western main drainage channel and Cannstatter Strasse and main Nesenbach main drainage channel, the Kurt-Georg-Kiesinger-Platz district heating and media duct, the Schlossgarten media duct, reconstruction of the S-Bahn and demolition of various facilities in the way.
