Copenhagen Metro

The Copenhagen Metro is a light rapid transit system serving Copenhagen, Frederiksberg, and Tårnby. It opened in October 2002 and operates four lines with 44 stations, 30 of which are underground. The M1 and M2 lines run to Amager and the airport, sharing tracks between the city centre and Vanløse. The M3 forms a circular route through central districts, while the M4 extends this circle to Nordhavn and Sydhavn. A fifth line, M5, is planned to serve Refshaleøen and Lynetteholmen, with opening expected in 2036. The system carries 135 million passengers annually and is one of only three rapid transit networks worldwide operating 24 hours a day. Owned by Metroselskabet, it uses driverless trains built by Hitachi Rail Italy, each three cars long and powered by a 750-volt third rail. Trains run every two to four minutes during the day, with longer intervals at night. The metro was developed alongside the Ørestad district, with construction beginning in 1996 after Parliament approved the project in 1992. The metro runs continually through tunnels and on elevated sections, linking key areas such as Copenhagen Central Station, Vesterbro, and the airport. Stations feature platforms built to accommodate future four-car trains, though current services use three-car sets. The system integrates with local DSB trains, regional Øresundståg services, and Movia buses. Its design minimises visual and noise impact while maximising speed and capacity, providing a reliable connection across the city.
