The M4 (the Harbour Line) is a future expansion of the Copenhagen Metro connecting Nordhavn in the north with Sydhavn in the south. The central part of the line shares tracks with the City Circle Line (M3) which is scheduled to open in February 2020.
|Stations||13 (under constuction)|
The Nordhavn branch was approved by the Danish Parliament in 2012 and is expected to open in 2020. The Sydhavn branch was approved in 2015 and is expected to open in 2024.
When the City Circle Line was planned, the M4 was intended to supplement the M3 from Nørrebro to København H providing increased metro capacity to the eastern section of the inner city. At this time, it was presumed that the M4 would eventually be expanded from Nørrebro to the northwestern suburbs, but this plan was abandoned in 2009, when the city of Copenhagen scrapped plans for an interchange facility under Nørrebro station. Instead, the city preferred a solution where the M4 would connect the Nordhavn and Sydhavn districts.

Possible future extensions
An extension in Nordhavn with 3 additional stations have been proposed, with the possibility of extending the line even further towards Hellerup Station.
Two possible extensions from Ny Ellebjerg Station in Sydhavnen are being looked into. One towards Hvidovre and one towards Bispebjerg. To enable such future extensions from the current M4 terminus, Ny Ellebjerg, it was decided in 2016 that the station would be built as an underground station instead of overground as previously decided.
