Technology: Chalice Columns for Stuttgart 21

Stuttgart 21 is a transportation and urban development project to redesign Stuttgart’s major rail interchange. Key to the project is the reconstruction of the old 16-platform, surface rail terminus station in Stuttgart to form a sub-surface, eight-platform, through station. Completion of the station is scheduled for 2025. Taking up the surface-level tracks and demolishing signal boxes releases around 100 hectares of land for new green space and the expansion of the urban centre.
