Rhomberg Bahntechnik, Züblin and DB Bahnbau Group win Stuttgart 21 contract
Major project: Rail technology companies lay the slab track at the new Stuttgart rail junction in a joint venture for Deutsche Bahn.
Stuttgart/Bregenz, 15 October 2020 - The Rhomberg Bahntechnik GmbH, together with Ed. Züblin AG and the DB Bahnbau Group, has secured the contract for two superstructure lots in the major project "Stuttgart 21". The project scope involves the slab track construction on two sections directly at the new underground main station of the state capital of Baden-Württemberg and between the airport and the Neckar river. In total, the joint venture is responsible for 41.4 kilometres of slab track, 72 switches, 2 crossings as well as various infrastructure works. The investment sum amounts to around 142 million euros.
The Deutsche Bahn subsidiary DB Bahnbau Group is taking over the commercial management of the overall contract. Züblin itself is responsible for the technical management of lot B at the station. The technical lead for lot D, between the Filder Tunnel on the Filder plain and the Neckar crossing near Wendlingen, will be handled by Rhomberg Bahntechnik. The Austrian railroad construction specialist can thereby ensure the seamless connection of the new sections of the Wendlingen-Ulm high-speed line: In another consortium, the subsidiary of the international Rhomberg Sersa Rail Group is already responsible for the 60 kilometres of slab track on the high-speed line between Wendlingen and Ulm.
One of the key elements of the Stuttgart 21 major contract is the installation of around 50 passable switches at the underground station, which will provide a short distance connection between the eight platform tracks and the adjacent tracks. In addition, the syndicate partners will install 8.6 kilometres of LED-handrail and 423 kilometres of cabling and mechanically equip five utility rooms. The tracks of the rail junction will also be equipped with passable track coverings up to the rescue tunnels to allow access for road rescue vehicles and thus make the track sections even safer. In addition, a heavy mass-spring system will be used to provide vibration protection at the tunnel portals.
"This contract is the biggest compliment for us for our successful project on the Alb plateau," explains Philipp Nachbaur, Managing Director at Rhomberg Bahntechnik. "We are very pleased to be able to continue to play our part in this important infrastructure project and to establish ourselves in Germany in the long term".
