The Cityringen project will form a new circular line in the city centre and will consist of two 17.4km tunnels and 17 new stations (two of which are transfer stations) all at 30 metres below ground level. From a technical point of view the project is extremely complex, since the city is at sea level. Tunnel excavation is by TBM. A cut and cover service tunnel is also foreseen for the connection to the operation and maintenance centre.

The fully automated driverless metro system will operate 24 hours a day, with a minimum frequency of 100 seconds, guaranteeing efficient mobility for 130 million metro passengers a year.

For Copenhagen this new metro line will mean a rapid, safe and environmentally sensible means of transportation.
