Istanbul Metro
The Istanbul Metro (Turkish: İstanbul metrosu) is a rapid transit railway network that serves the city of Istanbul, Turkey. Apart from the M11 line, which is operated by TCDD Taşımacılık, the system is operated by Metro Istanbul, a public enterprise controlled by the Istanbul Metropolitan Municipality. The oldest section of the metro is the M1 line, which opened on 3 September 1989. As of 2024, the system now includes 160 stations in service, with 36 more under construction. With 243.3 kilometers, Istanbul has the 21st longest metro system in the world and the 4th longest in Europe as of 2024.
The system consists of eleven lines: the lines designated M1A, M1B, M2, M3, M6, M7, M9 and M11 are on the European side of the Bosporus, while lines M4, M5 and M8 are on the Asian side. Due to Istanbul's unique geography and the depth of the Bosporus strait which divides the city, the European and Asian metro networks do not connect directly. The two parts of the city are linked through the Marmaray commuter rail line, which is connected to the metro in several places. Four metro lines are under construction on the Asian side: M10 (Pendik Merkez–Fevzi Çakmak), M12 (60. Yıl Parkı–Kazım Karabekir), M13 (Emek–Yenidoğan) and M14 (Altunizade–Bosna Bulvarı). Additionally, extension works on the M7 and M11 lines (on the European side) and the M4 and M5 lines (on the Asian side) are underway.
In addition to the Marmaray commuter rail, the metro connects to the F1, Tünel (F2), F3 and F4 funicular lines and with the network of the Istanbul Tram, Metrobüs and the cable cars.
The oldest underground urban rail line in Istanbul is the Tünel, which entered service on 17 January 1875. It is the world's second-oldest underground urban rail line after the London Underground which was built in 1863, and the first underground urban rail line in continental Europe, however this is not recognised as the opening of the metro due to the line being Funicular.
The first master plan for a full metro network in Istanbul, titled Avant Projet d'un Métropolitain à Constantinople and conceived by the French engineer L. Guerby, dates to 10 January 1912. The plan comprised a total of 24 stations between the Topkapı and Şişli districts and included a connection through the Golden Horn. Each station would have a 75-metre (246 ft 1 in) platform next to the rail line, while the distance between stations varied from 220 to 975 metres (721 ft 9 in to 3,198 ft 10 in). The blueprints of the project, which was never realized, are today displayed at the Istanbul Technical University Museum.
In 1936 the French urban planner Henri Prost proposed a metro network between the districts of Taksim and Beyazıt, to the north and south of the Golden Horn, respectively. In October 1951 the Dutch firm Nedeco proposed a similar route between Taksim and Beyazıt, and in September 1952 the Director of the Paris Transportation Department, Marc Langevin, prepared a 14-chapter report together with his associate Louis Meizzonet for the implementation of the project and its integration with the other means of public transportation in the city. However, these plans never came into effect and all proposals were put on hold until 1987, when the planning for the current Istanbul Metro was made.
Construction works for the first 'modern' mass transit railway system started in 1989, with the first stations opening in September. İstanbul Ulaşım A.Ş. (now known as Metro Istanbul) was founded the previous year to operate the system. The M1 was initially called "Hafif Metro" (which literally translates as "light metro"). Although it was built as a fully grade separated line, the M1 line operates with shorter trainsets and shorter station platforms than is standard on a traditional metro line, hence its "light metro" designation. The M1 line was later extended from Aksaray towards the western suburbs, reaching Atatürk Airport in the southwest in 2002.
Construction of the M2 line began on 11 September 1992, but faced many challenges due to the numerous archaeological sites that were discovered during the drilling process, which slowed down or fully stopped the construction of many stations, especially in the south. Taking into account the seismic activity in Istanbul, the entire network was built with the cut-and-cover method[citation needed] to withstand an earthquake of up to 9.0 on the Richter magnitude scale.
