As part of the major Stuttgart 21 project, the entire railway structure in the Stuttgart conurbation is being redesigned. The main focus is on converting the existing main terminus station into an underground through station. The remodelling of the centrally located main station means that the previous stabling station in Stuttgart's Rosenstein district has to make way. The future stabling station in Untertürkheim will replace it via a tunnel ring system.
The special feature and at the same time the challenge of the construction task lies in the special island location of the stabling station. The construction site in Untertürkheim measures around 17 hectares and is bordered in a north-south direction on one side by the Inter-Regio curve (road 4721), which is currently in operation, and on the other side by the suburban railway tracks and neighbouring residential buildings.
This special location makes the construction site logistics extremely important. Due to the limited track connection to the existing DB Netz line, the high volume of materials (soil, PSS, track ballast and general cargo such as prefabricated reinforced concrete parts) can only be delivered and removed via a central construction site access road.
The project team must always take these constraints into account in the planning and construction phases and harmonise them accordingly. This situation can only be improved to a limited extent via various project milestones.
