Copenhagen Metro

Copenhagen Metro (Danish: Københavns metro) is a rapid transit system serving Copenhagen, Frederiksberg and Tårnby in Denmark. The 20.5 kilometer system opened between 2002 and 2007, and has two lines, M1 and M2. The driverless light metro supplements the larger S-train rapid transit system, and is integrated with DSB local trains and Movia buses. Through the city center and west to Frederiksberg, M1 and M2 share a common line. To the south-east, the system serves Amager, with the 13.7 kilometer M1 running though the new neighborhood of Ørestad, and the 14.2 kilometer M2 serving the eastern neighborhoods and Copenhagen Airport. The metro has 22 stations, of which 9 are underground. In 2009, the metro carried 50 million passengers.
