each of M1 and M2. On Thursday, Friday and Saturday nights (24:00–05:00), the headway is fifteen minutes, and on other nights it is twenty minutes on all sections of the metro (M2 trains provide a shortened service when travelling at night on weekdays, during which time travellers between Lufthavnen and stations towards Vanløse must change trains at Christianshavn to M1.) At all other times, there is a six-minute headway. On the section shared with M1, there is half the headway (except during night on weekdays). Travel time along the whole line is 24 minutes, with the section from the airport to Nørreport taking 15 minutes and from Nørreport to Vanløse taking 9 minutes. The line is owned by Metroselskabet and operated by Metro Service. The line uses 34 AnsaldoBreda Driverless Metro vehicles that are shared with M1. The depot is located at the Service and Maintenance Center at Vestamager on M1. References Railway lines opened in 2002 Airport rail links 2002 establishments in Denmark
