Greater Copenhagen Light Rail (Danish: Hovedstadens Letbane, lit. 'The Capital City's Light Rail') is a planned electric light rail system crossing the lines of the S-train in Greater Copenhagen, Denmark, parallel to but outside the borders of Copenhagen Municipality. Its first stage is known as the Ring 3 Light Rail, for which construction started in 2018. It will go from Lundtofte Park north of Copenhagen to Ishøj station in the southwest, and it is expected to open in 2025, with an annual ridership of 13-14 million projected. The line will be owned by the Ringby-Letbanesamarbejdet (Ring city-Light rail cooperation), which is a collaboration between the municipalities serviced or affected by the line.
