Metro Copenhagen Cityringen will be a fully automated driverless metro ring line under the central part of Copenhagen. The line will consist of 17 underground stations, 16.5 km of twin tube TBM (Tunnel Boring Machine) -tunnels, 3 cross-over structures built in NATM (New Austrian Tunnel Method), 4 shafts and a maintenance and control center. In addition Cityringen will include an automated control and maintenance centre for operation and maintenance of the system.
Cityringen will be a system fully independent of the existing metro. It will have transfer facilities to the existing metro stations at Kongens Nytorf and Frederiksberg. Furthermore, there will be transfer facilities to the existing regional and commuter railway station at Københaven H station, at Østerport station and at Nørrebro station.
Where possible, the stations shall include daylight lit structures of high architectural quality. All platforms will be provided with platform screen doors and served by stairs, escalators and lifts.
In the project, Pöyry acted as the lead company of a design joint venture who provided design and consulting services in the bidding phase for the construction joint venture.
