About the M3 line
Cityringen — the M3, the red line — is the biggest thing to happen to Copenhagen transport in a century. It opened on 29 September 2019 after almost a decade of digging, and it is a true circle: seventeen stations, all underground, joined in a loop with no terminus at all. Trains run continuously in both directions, so you are never more than half a circle from anywhere on it.
The ring stitches together the neighbourhoods the old metro missed: Vesterbro and the Central Station, Frederiksberg, Nørrebro, Østerbro and the inner city. The full circle takes about 21 minutes, which means no journey on it is longer than roughly ten. Every station was given its own architectural identity, and several — Marmorkirken, Gammel Strand, Rådhuspladsen — are worth a look in their own right.
You can change to the M1 and M2 at Frederiksberg and Kongens Nytorv, and to the M4 along the shared central tunnel between København H and Østerport. S-trains connect at København H, Østerport and Nørrebro.
