M1 of the Copenhagen Metro, colored green on the map, runs from Vanløse to Vestamager. It connects the Ørestad neighborhood of Copenhagen, Denmark, to the city center. The line is elevated while traveling through Ørestad, while it runs in a tunnel below the city center. From Christianshavn to Vanløse, the line is shared with M2. History The background for the metro was the urban development of the Ørestad area of Copenhagen. The principal of building a rail transit was passed by the Parliament of Denmark on 24 June 1992, with the Ørestad Act. The responsibility for developing the area, as well as building and operating the metro, was given to the Ørestad Development Corporation, a joint venture between Copenhagen Municipality (45%) and the Ministry of Finance (55%). Initially, three modes of transport were considered: a tramway, a light rail and a rapid transit. In October 1994, the Development Corporation chose a light rapid transit system. The decision to build stage 2, from Nørreport to Vanløse was made by parliament on 21 December 1994. Stage 2 involved the establishment of the company Fredriksbergbaneselskapet I/S in February 1995, owned 70% by the Ørestad Development Corporation and 30% by Fredriksberg Municipality. In October 1996, a contract was signed with the Copenhagen Metro Construction Group (COMET) for building the lines, and with Ansaldo for delivery of the trains and operate the system the first five years. COMET is a consortium comprised Astaldi, Bachy, SAE, Ilbau, NCC Rasmussen & Schiøtz Anlæg and Tarmac Construction. Construction started in November 1996, with the moving of underground pipes and wires around the station areas. In August 1997, construction started at the depot, and in September, COMET started the first mainline construction work. In October and November, the two tunnel boring machines (TBM), christened Liva and Bette, were delivered. They started digging each barrel of the tunnel from Islands Brygge in February 1998. The same month, the Public Transport Authority gave the necessary permits to operate a driverless metro. The section between Fasanvej and Frederiksberg is a former S-train line, and was last operated as such on 20 June 1998. The first section of tunnel was completed by September 1998, and the TBMs moved to Havnegade. By December 1998, work had started on all the initial nine stations. Plans for M2 were presented to the public in April 1999, with a debate emerging if the proposed elevated solution is
