Background in the background The planning of the metro was spurred by the development of the
Ørestad area of Copenhagen. The principle 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 were considered: a tramway, a light rail and a rapid transit. In October 1994, the Development Corporation chose a light rapid transit. The tram solution would have been a street tram, without any major infrastructure investments in the city centre, such as a dedicated right-of-way. Through Ørestad it would have had level crossings, except for a grade-separated crossing with the
European Route E20 and the
Øresund Line. It would have had a driver and have operated at about a 150-second interval—twice the cycle time of the city's traffic lights. Power would have been provided with
overhead wires. Stops were to be located about every at street level. The articulated trams would have been about long and have a capacity for 230 passengers. The light rail model would have used the same approach as the tram in Ørestad, but would instead have run through a tunnel in the city centre. The tunnel sections would be shorter, but the diameter larger because it would have to accommodate overhead wires. The system would have the same frequency as the tram, but use double trams and would therefore require larger stations. The metro solution was chosen because it combined the highest average speeds, the highest passenger capacity, the lowest visual and noise impact, and the lowest number of accidents. Despite requiring the highest investment, it had the highest
net present value.
Construction of lines M1 and M2 Construction started in November 1996, with the moving of underground pipes and wires around the station areas. In August 1997, work started at the depot, and in September, COMET started the first mainline work. In October and November, the two
tunnel boring machines (TBM), christened Liva and Betty, were delivered. They started boring 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. Operation of the system was subcontracted to Ansaldo, who again subcontracted it to Metro Service, a subsidiary of
Serco. The contract had a duration of five years, with an option for extension for another three.
Opening of lines M1 and M2 Trial runs on stage 2A began on 24 February 2003 and opened on 29 May. All changes to bus and train schedules in Copenhagen took place on 25 May, but to allow
Queen Margrethe II to open the line, the opening needed to be adapted to her calendar. This caused four days without a bus service along the line. Stage 2B, from Frederiksberg to Vanløse, opened on 12 October.
Forum Station was nominated for the
European Union Prize for Contemporary Architecture in 2005. On 2 December 2005, the final agreement to build the City Circle Line was made between the local and national governments. The price was estimated at 11.5 to 18.3 billion
Danish krone (DKK), of which DKK 5.4 billion will be financed though ticket sales, and the remaining from the state and municipalities. In 2006, it was announced that the contract with Ansaldo to operate the metro had been prolonged another three years. The Ørestad Development Corporation was discontinued in 2007, and the ownership of the metro was transferred to Metroselskabet I/S. In January 2007, the city council decided that a branch was to be built during construction at Nørrebro, to allow a future branch line from the City Circle Line towards
Brønshøj. The first part of this line was intended to be constructed at the same time as the City Circle Line, to avoid a multitude-higher construction cost and long interruptions of operations later. This did not involve a final decision, only an option for future construction. The Herlev/Brønshøj line was ultimately dropped as the City of Copenhagen withdrew its share of the cost of the Nørrebro branch chamber in its 2009 budget, and the state refused to continue the project. Any branch to the Herlev / Brønshøj region would now require a shutdown of the City Circle Line for an extended period of time. In March 2007, a proposal to establish a station at
Valby, where the
Carlsberg Group is planning an urban redevelopment, was scrapped. The proposal would have increased construction costs by DKK 900 million and was deemed not economical. The increased cost was, in part, due to an extra TBM being needed to complete the project on time. The City Circle Line was passed by parliament on 1 June 2007, with only the
Red–Green Alliance voting in disfavor. The stage 3 opened on 28 September 2007, from Lergravsparken to the airport. It followed, for the most part, the route of the former
Amager Line of the
Danish State Railways. With this stage complete, the 34 trains were delivered for use by the M1 and M2. However, the line caused a heated debate, with several locals organized themselves into the Amager Metro Group. The group argued that the line should have been built underground, citing concerns that it would create noise pollution and a physical barrier in Amager. In April 2008, the Copenhagen Metro won the award at MetroRail 2008 for the world's best metro. The jury noted the system's high regularity, safety and passenger satisfaction, as well as the efficient transport to the airport. During 2008, the metro experienced a 16% passenger growth to 44 million passengers per year. Several parties agreed in September 2008 not to fund a northwest expansion of the metro. Initially, the system operated trains from 01:00 to 05:00 only on Thursdays to Saturdays, but, starting on 19 March 2009, night service was extended to the rest of the week. This caused a logistical challenge, because Metro Service used the nights for maintenance. The routes were therefore set up in such a way that the system could be operated on only a single track, leaving the other free for work. In May 2009, six companies were pre-qualified to bid for the
public service obligation to operate the metro. These were
Serco-NedRailways,
Ansaldo STS,
Arriva,
S-Bahn Hamburg,
Keolis and DSB Metro—a joint venture between
DSB and
RATP. The process was delayed because of a procedural error by Metroselskabet, who failed to pre-qualify DSB Metro.
Construction of lines M3, City Circle line and M4, the Harbour Line An expansion of the metro, the City Circle Line, opened on 29 September 2019. Independent of the existing system, it circles the city centre and connects the areas of
Østerbro,
Nørrebro and
Vesterbro to Frederiksberg and
Indre By. The line is long and runs entirely in the tunnel. The circle has 17 stations, two of which are interchanges with both the M1 and M2 lines and three
Copenhagen S-train stations. It takes 25 minutes to complete a full lap in either direction. Archaeological and geological surveys started in 2007, preferred bidders were announced in November 2010, Preparations began by moving utilities, etc., in 2010, and construction of work sites and stations began in 2011. Drilling of tunnels began in 2013. Lines M3 and M4 serve the City Circle Line. The M3 opened on 29 September 2019, and its trains operate on the entire circle in either direction. The M3 has transfers to M1 and M2 at Frederiksberg and
Kongens Nytorv. The line is estimated to carry 240,000 daily passengers, bringing the metro's total daily ridership to 460,000. The M4 was opened on 28 March 2020 when two additional stations were opened in the Nordhavn district. This line runs from
Copenhagen Central Station (København H) via
Østerport to Orientkaj station in Nordhavn, thus sharing six stations with the M3 and featuring two additional Nordhavn stations. The M4 line is interchange with the M1 and M2 at
Kongens Nytorv. An extension to the Sydhavn district opened on 22 June 2024, served by the M4. The addition of this line relocated the M4's southern terminus from Copenhagen Central Station to København Syd. The northern extension,
Nordhavn station and Orientkaj station, both began service on 28 March 2020. The southern extension will add five additional stops to the M4, with its southern terminus moving from
Copenhagen Central Station to Ny Ellebjerg. This line will service the southern harbour district and is expected to open by 2024. As of 2019, the M1 and M2 has a total of 22 stations. After opening of the City Circle Line, the metro system is featured 3 lines with a total of 37 stations. Upon completion of both extensions of the M4, the system will feature four lines with 44 stations. 8 of these will be interchanges with the
S-train. == Future lines discussed ==
