I’ve just started working on a really interesting project for the Copenhagen Metro. They’ve got a ‘city ring’ opening in 2018, that involves two new train lines, that will intersect with the current M1 and M2 in accordance with the temporary map above, which is currently on the Metro website. There might also be extension north from Nørrebro and the future will definitely see additional lines added. See the website for all public information about the Cityring project.
