Istanbul Metro

The Istanbul Metro (Turkish: İstanbul metrosu) is a rapid transit railway network that serves the city of Istanbul, Turkey. It is operated by Metro Istanbul, a company (formerly known as İstanbul Ulaşım A.Ş. before 2016[5]), a public enterprise, controlled by the Istanbul Metropolitan Municipality. The oldest section of the metro is the M1 line, which opened in 1989; it now includes 107 stations in service,[1] with 104 more under construction.

The ‘M’ logo, at the station entrance and passenger direction signs, should not be confused with the ‘Metro Istanbul’ logo, the company that operates the train system throughout Istanbul.[4]

The system consists of eight lines named M1, M2, M3, M4, M5, M6, M7 and the M9. More lines are under construction or planned: M8 (Bostancı-Dudullu) and the M12 (Göztepe-Ümraniye) will be on the Asian side, while M11 (Gayrettepe-Istanbul Airport) will be on the European side.[6]

Istanbul Metro is connected with the underground systems of the Marmaray tunnel (which connects the lines on the city's European and Asian sides) and the F1 funicular, and with the surface network of the T1 and T4 tram systems as well as the T5 tram.[7]

History
Karaköy station of the Tünel, which entered service on 17 January 1875.

The oldest underground urban rail line in Istanbul is the Tünel, which entered service on 17 January 1875.[8] It is the world's second-oldest underground urban rail line after the London Underground which was built in 1863,[9] and the first underground urban rail line in continental Europe.

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.[10] 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 platform next to the rail line, while the distance between stations varied from 220 to 975 metres. 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.[11][12] 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.

Levent (left) and Şişli (right) stations of the M2 line in 2009

Construction works for the first 'modern' mass transit railway system started in 1989. 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.[13]

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 at the south. Taking into account the seismic activity in Istanbul, the entire network was built with the cut-and-cover method to withstand an earthquake of up to 9.0 on the Richter magnitude scale.[14][15]

The Golden Horn Metro Bridge entered service in 2014.

The first section between Taksim and 4. Levent entered service, after some delays, on 16 September 2000. This line is 8.5 km (5.3 mi) long and has 6 stations, which all look similar but are in different colours. In 2000, there were 8 Alstom-built 4-car train sets in service, which ran every 5 minutes on average and transported 130,000 passengers daily. On 30 January 2009, the first train sets built by Eurotem entered service.[16] Eurotem will build a total of 92 new wagons for the M2 line.[16][17] As of 30 January 2009, a total of 34 trainsets, each with 4 cars, were being used on the M2 line.[17] A northern extension from 4. Levent to Maslak was opened on 30 January 2009.[18] On 2 September 2010 the northern (temporary) terminus Darüşşafaka followed.[19] The southern extension of the M2 line from Taksim to Yenikapı, across the Golden Horn via Haliç station on the bridge and underground through the historic peninsula, entered service on 15 February 2014. The Taksim-Yenikapı extension is 5.2 km long, with four stations. The total cost of the extension was $593 million.[20] At Yenikapı it will intersect with the extended M1 line and the Marmaray commuter line.

M4 Yenisahra Station

The trip between the Şişhane station in Beyoğlu and the Haciosman station in Maslak is 20 km (12.4 mi) long and takes 27 minutes; including Şişhane - Taksim (1.65 km, 2 minutes), Taksim - 4. Levent (8.5 km, 12 minutes), and 4. Levent - Haciosman (8.1 km, 12 minutes.)[21][22] The total length of the European side of the M2 line will reach 23 km (14.3 mi) when all 16 stations from Hacıosman to Yenikapı will be completed;[23][24][25] not including the 936-metre-long Golden Horn Metro Bridge,[26] the 0.6 km long Taksim-Kabataş tunnel connection with the Seabus port,[27] and the 0.6 km long Yenikapı-Aksaray tunnel connecting the M1 line to the Yenikapı Transfer Center.[25]

On the Asian side, construction is in progress of the remaining portion of the 26.5 km (16.5 mi) long M4 line from Kadıköy to Kaynarca, yielding a total of 19 stations. It cost €751 million and was built by the Astaldi / Makyol / Gülermak consortium.[28] The first section opened on 17 August 2012, terminating in Kartal. Construction of the 20 km (12.4 mi) long M5 line from Üsküdar via Ümraniye to Sancaktepe started in March 2012.[29]

Network map

The Metro operates from 06:00 AM to 00.00 AM every 6–12 minutes. M2 Yenikapı - Hacıosman operates from 06:00 AM to 00.00 AM. During peak hours the intervals could be reduced to 3 to 4 minutes. There is a flat fare – 3.50 TL with Istanbulkart only. The Marmaray fare is 7.75TL, but it may refund a portion of it depending on the number of stops you travelled through. The Metrobüs works in a similar way and the fare is 3.85 TL with refunds. The refunds can be collected from the refund machines that can be found at each station. All means of transport provide a discount for interchanges except Metrobüs.[30] Istanbulkart is also valid, which is the most popular method for long-distance travelling. The Istanbulkart is valid on all metros, trams, funiculars, ferry boats and buses. Ferryboat and bus fares are not flat, so the price of this transfer ticket also varies depending on the distance to be covered on bus or ferryboat.

Night operations

During August 2019 the Mayor of Istanbul, Ekrem İmamoğlu, announced that many lines of Istanbul were going to provide 24 hours service during weekends with trains at 20 minutes interval.[31] Since August 2019, the Istanbul Metro started to provide 24 hours service for some lines at weekends and public holidays but this service was discontinued in March 2020 due to coronavirus pandemic. M1A Yenikapi-Atatürk Airport, M1B Yenikapi-Kirazli, M2 Yenikapi-Haciosman, M4 Kadikoy-Tavsantepe, M5 Uskudar-Cekmekoy and M6 Levent-Bogazici University/Hisarustu.[32]

Stations
Main article: List of Istanbul Metro stations
M2 (Istanbul Metro) (left) and Golden Horn Metro Bridge Station (right)

The Istanbul Metro system has a total of 107 stations in operation with 104 more under construction. Since the majority of the system is underground, stations are generally accessed going down from street level. At every entrance to the metro is a post with the Istanbul metro "M" logo and the station name underneath it. Entrances are usually built into sidewalks along a street, although many stations of newer lines have their entrances from street level on small plazas.

Out of the 107 operating stations of the Istanbul Metro:

  • 91 are fully underground
  • 7 are elevated stations
  • 7 are on an embankment or at-grade
  • 2 are partially underground

Mezzanines
The mezzanine concourse at Yenikapı station (M1 and M2)

Most stations have a mezzanine directly below street level, which allows passengers to enter the stations from multiple locations and proceed to the correct platform without having to cross any streets. Inside the mezzanines are ticket machines and turnstiles, where passengers must pay to enter fare control zones and proceed to the trains.

In some stations, mezzanines connect directly to nearby buildings and structures, such as shopping malls or business centres. Each station concourse or mezzanine are patrolled by Istanbul Metro security guards to prevent fare evasion and crime.

Stations with large walkways toward different exits, such as Taksim also have travelators to cover the long walking distances.

Upon entering the station, passenger may use ticket vending machines or manned ticket booths to purchase their fare, which can be stored on the Istanbulkart contactless smart card. After entering the fare-controlled area, via the turnstiles, passengers may continue further down to the platform level.

Platforms
Yenikapı (left) on the M1 and M2 lines and Bostancı (right) on the M4 line are among the stations which have two island platforms and three tracks

Since the different lines of the Istanbul Metro have different specifications, most notably car length, there is no uniform length for platforms. The oldest platforms of the network, built between 1989 and 2002 on the M1 line, are 100 m (328 ft 1 in) and can accommodate trains up to 4 cars long. Platforms on the M2, M3 and M4 lines span about 150 m (492 ft 2 in) and can each accommodate trains up to 8 cars long. Platforms on the M5 line can accommodate up to 6-car trains, whiles platforms on the M6 line accommodate 4-car trains.

Sections of platforms are subject to close during off-peak hours, especially on the M2 line. While platforms on the M2 line are open fully during peak hours, capacity is reduced to 4-car trains during off-peak hours. Platforms on the M5 line are protected by platform edge doors. Except on funicular lines, most platforms of the Istanbul Metro consist of two side platforms or one island platform. Five stations consist of two island platforms, serving three tracks. These stations are Otogar on the M1 line, Yenikapı and Sanayi on the M2 line, Olimpiyat on the M9 line, and Bostancı on the M4 line.

Alignment and interchanges
M3 Mahmutbey Metro Station
M4 Ayrılıkçeşmesi Metro Station

The lines have no connection between them. Apart from the Haliç station on the M2 line, about half of the M1 (mostly M1A) line, Alibeyköy and Kağıthane valleys crossing by the M7 line and viaduct section at Olimpiyat of the M9 line, the lines are fully underground. All station names are on the bus lines as well.

The M2 line has an interchange between F1 in Taksim and an interchange tunnel with the Zincirlikuyu Metrobus station at the Gayrettepe station.[43] There is also a transfer station at Yenikapı with Marmaray, M1 line and İDO Ferry Port; from where it is possible to take the high-speed catamaran Seabus departing for Bursa, Bandırma or Yalova; as well as the other Seabus ports of İstanbul such as Bostancı, Kadıköy, Bakırköy and Kabataş.

The M3 line has an interchange with the M1B line at the Kirazlı station.

The M4 line has a vapur (traditional ferry), motorboat, İDO and nostalgic tram interchange at Kadıköy which is the heart of İstanbul's Asian side. One can also interchange to Marmaray at the Ayrılık Ceşmesi station. Also at Ünalan / Uzunçayır, the line has a Metrobus interchange just like Gayrettepe in M2.

The M5 line has an interchange with the Marmaray and İDO at the Üsküdar station. Also at Altunizade the line has a Metrobus interchange.

The M6 line has an interchange with the M2 line at the Levent station.

The M7 line interchanges with the M2 line at the Mecidiyeköy station, with the T4 tramway line at the Kiptaş-Venezia/Karadeniz station, and with the M3 at the Mahmutbey station.

The M9 has an interchange with the M3 at Ikitelli station.

Rolling stock
Interior of M2 rolling stock

Although line M1 is a (light) metro line, its rolling stock—in use since 1989—is made up of typical ABB light rail vehicles (LRVs). These are partly the same as those used on the T4 tramway line.

The first Istanbul full metro rolling stocks, which entered service on 16 September 2000, on the Taksim - 4. Levent line, were built by Alstom. These trains are air-conditioned and equipped with LCD screens, and share a similar exterior design to the first three generations of rolling stock used on the Caracas Metro in Venezuela.

On 30 January 2009, the first 8 trains (each with 4 wagons) built by Eurotem (the Turkish factory of Hyundai Rotem) entered service.[44] Today the system has 268 trains.[1] These trains are also air conditioned and equipped with LCD screens, as well as dynamic route map showing the location and direction of the train.[45]

In September 2009, CAF signed a contract to supply 144 units for the M4 line, amounting to 1.156.159 euros. These metro units are formed with 4 cars for a total length of 90 meters and have a maximum transport capacity of 1300 passengers.[46]

Future extensions
Istanbul rail transit network map

As part of the Istanbul Metropolitan Municipality goal of expanding the size of the city rail transportation network to 630 km (390 mi) by 2030,[47] the Istanbul Metro has several lines that are under construction or planned. Since the city does not have a widespread railway network, the Metropolitan Municipality aims to connect urban areas of the city that do not have access to the Istanbul two coastal railways with metro lines.

None of the current Istanbul Metro lines cross the Bosphorus; lines are wholly located either on the European side or the Asian side of the city. In 2019, The Ministry of Transport and Infrastructure began the planning of a 30.2 km (18.8 mi) line that would link İncirli with Söğütlüçeşme via a tunnel under the Bosphorus also designed to accommodate road traffic.[48]

The following metro lines are under construction:
