3 July 2013  •  Author(s): Erik Skotting, Director (COO), Metroselskabet

The first Tunnel Boring Machine (TBM) is ready to start tunnelling on Copenhagen’s new metro line – the City Circle Line, or Cityringen. The Cityringen contract was awarded in January 2011 and the main construction work started in the following summer. The contract covers 15.5km of twin-bored tunnels, 17 stations and three shaft structures as well as a new Control and Maintenance Centre. In summer 2013, the first TBM will start the tunnelling from one of the three shafts – 40m underground at the work site in Nørrebroparken.

During the past 10 years, the two-line Metro in Copenhagen has grown increasingly popular and as a result of this, the public has demanded more lines. In 2007 the Danish Parliament decided on building a new route called Cityringen. The Cityringen project com – prises a circular underground line within the city closely modelled on the existing metro with the same high-frequency service and short trains.

By 2018 the Cityringen line and 17 new stations will almost double the number of metro stations in the Danish capital.
