The '''Istanbul Metro''' ({{langx|tr|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 159 stations in service,<ref name="network"/> with 36 more under construction. With 243.3 kilometers,  Istanbul has the 21st longest metro line in the world and the 4th longest in Europe as of 2024.<ref>{{cite web | url=https://www.enerjiatlasi.com/ulkelere-ve-sehirlere-gore-metro-uzunlugu | title=Metro Uzunluğu - Ülkelere ve Şehirlere Göre }}</ref>

The system consists of eleven lines: the lines designated [[M1A (Istanbul Metro)|M1A]], [[M1 (Istanbul Metro)|M1B]], [[M2 (Istanbul Metro)|M2]], [[M3 (Istanbul Metro)|M3]], [[M6 (Istanbul Metro)|M6]], [[M7 (Istanbul Metro)|M7]], [[M9 (Istanbul Metro)|M9]] and [[M11 (Istanbul Metro)|M11]] are on the European side of the [[Bosporus]], while lines [[M4 (Istanbul Metro)|M4]], [[M5 (Istanbul Metro)|M5]] and [[M8 (Istanbul Metro)|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 (Istanbul Metro)|M10]] (Pendik Merkez–Fevzi Çakmak), [[M12 (Istanbul Metro)|M12]] (60. Yıl Parkı–Kazım Karabekir), [[M13 (Istanbul Metro)|M13]] (Emek–Yenidoğan) and [[M14 (Istanbul Metro)|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 Taksim–Kabataş funicular line|F1]], [[Tünel]] (F2), [[F3 (Istanbul Metro)|F3]] and [[F4 (Istanbul Metro)|F4]] [[funicular]] lines and with the network of the [[Istanbul Tram]],<ref>{{Cite web|title=Cibali-Alibeyköy Cep Otogarı Tramvay Hattı|url=https://www.metro.istanbul/Hatlarimiz/HatDetay?hat=T5|access-date=4 January 2021|website=metro.istanbul}}</ref> [[Metrobus (Istanbul)|Metrobüs]] and the cable cars.

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.<ref>[http://entreprises-coloniales.fr/proche-orient/Consortium_de_Constantinople.pdf CONSORTIUM DE CONSTANTINOPLE, Bruxelles] (French)</ref> The plan comprised a total of 24 stations between the [[Fatih|Topkapı]] and [[Şişli]] districts and included a connection through the [[Golden Horn]]. Each station would have a {{Convert|75|m|ftin|adj=on}} platform next to the rail line, while the distance between stations varied from {{Convert|220 to 975|m|ftin}}. 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 Square|Taksim]] and [[Beyazıt Square|Beyazıt]], to the north and south of the Golden Horn, respectively.<ref>{{Cite web|url=http://www.imo.org.tr/resimler/dosya_ekler/fa2e5f88158974c_ek.pdf?dergi=180|title=TMMOB: "İstanbul Ulaştırmasının Dünü, Bugünü" (Güngör Evren)|access-date=25 July 2012|archive-date=24 September 2015|archive-url=https://web.archive.org/web/20150924034013/http://www.imo.org.tr/resimler/dosya_ekler/fa2e5f88158974c_ek.pdf?dergi=180|url-status=dead}}</ref><ref>{{Cite web |url=http://www.megaron.yildiz.edu.tr/yonetim/dosyalar/03-01-Megaron-104-111.pdf |title=Yıldız Technical University Faculty of Architecture Magazine (Megaron): "İki Fransız mimarı Henri Prost ve August Perret'nin İstanbul ile ilgili çalışmaları" (Işık Aydemir) |access-date=25 July 2012 |archive-url=https://web.archive.org/web/20160304034924/http://www.megaron.yildiz.edu.tr/yonetim/dosyalar/03-01-Megaron-104-111.pdf |archive-date=4 March 2016 |url-status=dead }}</ref> 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.{{Multiple image

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 separation|grade separated]] line, the M1 line operates with shorter [[Train#Terminology|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.<ref>{{cite web |url=http://www.urbanrail.net/as/tr/istanbul/istanbul.htm |title=Europe > Turkey > ISTANBUL Metro |website=UrbanRail.Net |access-date=12 August 2013}}</ref>

Construction of the M2 line began on 11 September 1992, but faced many challenges due to the numerous [[History of Istanbul|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|cut-and-cover method]]{{Citation needed|date=August 2012}} to withstand an earthquake of up to 9.0 on the [[Richter magnitude scale]].<ref>{{Cite web|url=http://arsiv.ntv.com.tr/news/30122.asp|title=10 soruda İstanbul Metrosu...|website=arsiv.ntv.com.tr}}</ref><ref>{{Cite web|url=http://www.ibb.gov.tr/tr-TR/SubSites/raylisistemler/Pages/taksim-4Levent.aspx|archive-url=https://web.archive.org/web/20090626072411/http://www.ibb.gov.tr/TR-TR/SUBSITES/RAYLISISTEMLER/Pages/taksim-4Levent.aspx|url-status=dead|title=Istanbul Metropolitan Municipality: "İstanbul Metrosu: Taksim – 4.

This line is {{convert|8.5|km|mi|2|abbr=on}} 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.

The Istanbul Metro system has a total of 159 stations in operation with 35 more under construction. Since the majority of the system is underground, stations are generally accessed going down from street level. At every station entrance there is a post with the Istanbul metro "M" logo and the station name underneath it except for the M11 line which has the "U" logo next to its own entrances.<ref>{{Cite web |title='U' harfi metroya erişimi kolaylaştırırmış |url=https://www.birgun.net/haber/u-harfi-metroya-erisimi-kolaylastirirmis-383355 |access-date=2023-07-29 |website=[[BirGün]] |language=tr}}</ref><ref>{{Cite web |last= |first= |date=2021-09-08 |title=U or M?

Like [[Moscow Metro]], the majority of the stations of the Istanbul Metro are generally deep level due to the city's hilly geography.

Out of the 159 operating stations of the Istanbul Metro:

* 143 are fully underground 
* 7 are elevated stations
* 7 are on an embankment or at-grade
* 2 are partially underground

===Mezzanines===
[[File:Yenikapi_metro_station_6244.jpg|thumb|left|200px|The [[mezzanine]] concourse at [[Yenikapı Transfer Center|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 [[Paid area|fare control]] zones and proceed to the trains.<ref>{{Cite web |title=Üsküdar - Çekmeköy metro hattı asma tavan uygulamaları tamamlandı. - Okro Yapı Sistemleri |url=https://www.okro.com.tr/haberdetay-uskudar-cekmekoy-metro-hatti-asma-tavan-uygulamari-tamamlandi-16 |access-date=2023-07-29 |website=okro.com.tr |archive-date=29 July 2023 |archive-url=https://web.archive.org/web/20230729152422/https://www.okro.com.tr/haberdetay-uskudar-cekmekoy-metro-hatti-asma-tavan-uygulamari-tamamlandi-16 |url-status=dead }}</ref><ref>{{Cite web |title=M1A Hattında 3 İstasyon İşletmeye Kapatılıyor |url=https://www.metro.istanbul/duyuru/detay/m1a-hattinda-3-istasyon-isletmeye-kapatiliyor#gallery-1 |access-date=2023-07-29 |website=metro.istanbul}}</ref>

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 (Istanbul Metro)|Taksim]], also have [[Moving walkway|travelators]] to cover the long walking distances.

Upon entering the station, passengers may use ticket vending machines or staffed 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===

| footer = [[Yenikapı Transfer Center|Yenikapı]] (left) on the M1 and M2 lines and [[Bostancı (M4)|Bostancı]] (right) on the M4 line are among the stations which have two [[island platform]]s and three tracks
}}

Since the different lines of the Istanbul Metro have different specifications, most notably [[Railcar|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 {{convert|100|m|abbr=on|ftin}} and can accommodate trains up to 4 cars long. Platforms on the M2, M3, M4, M7 and M11 lines span about {{convert|180|m|abbr=on|ftin}} 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, M8, and M9 lines are 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, M7, M8 and M11 lines are protected by platform edge doors. Except on funicular lines, most platforms of the Istanbul Metro consist of two [[side platform]]s or one [[island platform]]. Five stations consist of two island platforms, serving three tracks in a configuration known as the [[Spanish Solution]]. These stations are [[Otogar (Istanbul Metro)|Otogar]] on the M1 line, [[Yenikapı Transfer Center#M2 platform|Yenikapı]] and [[Sanayi (Istanbul Metro)|Sanayi]] on the M2 line, [[Olimpiyat (Istanbul Metro)|Olimpiyat]] on the M9 line, and [[Bostancı (M4)|Bostancı]] on the M4 line.

=== Design ===
The stations on the M1 line, which were built in the 1980s and 1990s, are very functional and plain in design. Like many stations built during this period, the stations use fluorescent tubes as light sources, and are decorated with [[Floor tile|tiled floors]] and ceiling panels made of white plastic ceiling slats. Platforms of stations on the M1 line are supported by square and tiled central columns (e.g. Aksaray, Emniyet - Fatih and Topkapı - Ulubatlı.) 

Stations on the M2 line built between 2000 and 2011, care was taken to use [[light colors]]. For this reason, the basic wall color of the stations is white. In order to make people not confuse the stations and to make them more memorable, some characteristic patterns were also implemented. (e.g. colored stripes/tiles on walls).

Stations on the M7 line, which were built between 2017 and 2020, mostly use a combination of gray and white colors. Since the line has fully automated driverless vehicles, passengers are prevented from falling onto the tracks by using [[platform screen doors]] (PSDs).<gallery mode="packed">

==Alignment and interchanges==
[[File:Mahmutbey_Metro_Station.jpg|thumb|right|M3 Mahmutbey Metro Station]]
[[File:Ayrılıkçeşmesi_M4.JPG|thumb|left|M4 Ayrılıkçeşmesi Metro Station]]
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, viaduct section at Menekşe River of the M3 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.<ref>[http://www.ibb.gov.tr/tr-TR/Pages/Haber.aspx?NewsID=19719 İstanbul Büyükşehir Belediyesi]. Ibb.gov.tr. Retrieved on 12 August 2013.</ref> There is also a transfer station at Yenikapı with [[Marmaray]], [[M1 (Istanbul Metro)|M1 line]] and [[İDO]] Ferry Port; from where it is possible to take the high-speed catamaran [[İDO|Seabus]] departing for [[Bursa]], [[Bandırma]] or [[Yalova]]; as well as the other Seabus ports of Istanbul such as [[Bostancı]], [[Kadıköy]], [[Bakırköy]] and [[Kabataş, Istanbul|Kabataş]].

The M3 line has an interchange with the M9 line at the İkitelli Sanayi station, M7 line at the Mahmutbey station, M1 line at the Kirazlı station, M2, M1 and Metrobus at the İncirli station, and lastly Marmaray (B1) and YHT at Özgürlük Meydanı Station.

The M4 line has a vapur (traditional ferry), motorboat, [[İDO]] and nostalgic tram interchange at [[Kadıköy]] which is the heart of Istanbul's Asian side. One can also interchange to [[Marmaray]] at the [[Ayrılık Çeşmesi (Istanbul Metro)|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 (Istanbul Metro)|Üsküdar station]]. Also at [[Altunizade (Istanbul Metro)|Altunizade]] the line has a Metrobus interchange.

The M6 line has an interchange with the [[M2 (Istanbul Metro)|M2]] line at the [[Levent (Istanbul Metro)|Levent station]].

The M7 line interchanges with the [[M2 (Istanbul Metro)|M2]] line at the Mecidiyeköy station, with the [[T4 (Istanbul Tram)|T4 tramway line]] at the Kiptaş-Venezia/Karadeniz station, and with the [[M3 (Istanbul Metro)|M3]] at the Mahmutbey station.

The M8 line has an interchange with the Marmaray at the Bostancı station, with the M4 line at the Kozyatağı station and with the M5 line at the Dudullu station.

The M9 has an interchange with the [[M3 (Istanbul Metro)|M3]] at Ikitelli station.

The M11 line interchanges with the M2 line and Metrobus at Gayrettepe station, and with the M7 line at Kağıthane station.

==Rolling stock==
{{Expand section|date=October 2023}}
Aside from running on standard gauge tracks and all models having 4 doors per side, the rolling stock is generally incompatible, with few track connections to other lines and rolling stock generally will never run on any line other than whatever they first were delivered to. As each line is generally self-contained, this has rarely become an issue.

[[File:M7 Tren içi.jpg|thumb|Interior of M7 rolling stock]]The first Istanbul full metro rolling stocks, which entered service on 16 September 2000, on the [[Taksim Square|Taksim]] - [[Levent|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|Eurotem]] (the Turkish factory of [[Hyundai Rotem]]) entered service.<ref>{{Cite web|url=http://www.ibb.gov.tr/tr-TR/SubSites/raylisistemler/Pages/taksimyenikapielektro.aspx|archive-url=https://web.archive.org/web/20090505070833/http://www.ibb.gov.tr/tr-TR/SubSites/raylisistemler/Pages/taksimyenikapielektro.aspx|url-status=dead|title=Istanbul Metropolitan Municipality: Taksim-Yenikapı Metro Hattı|archive-date=5 May 2009}}</ref> Today the system has 268 trains.<ref name="network"/> 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.<ref name="istanbululasim.com">[https://web.archive.org/web/20220314071925/https://www.istanbululasim.com/default.asp?ml_pn=1&menu_id=7&makale_tip=guncel&makale_id=00163.txt&modul_id=guncel İstanbul Ulaşım: Metro Şişhane'den Maslak'a uzandı]</ref>

In September 2009, [[Construcciones y Auxiliar de Ferrocarriles|CAF]] signed a contract to supply 144 units for the [[M4 (Istanbul Metro)|M4]] metro line, amounting to 1.1 million 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.<ref>[http://www.ibb.gov.tr/tr-TR/SubSites/raylisistemler/Pages/kadikoy-kartal120.aspx İstanbul Büyükşehir Belediyesi] {{webarchive|url=https://web.archive.org/web/20131012020325/http://www.ibb.gov.tr/tr-TR/SubSites/raylisistemler/Pages/kadikoy-kartal120.aspx |date=12 October 2013 }}. Ibb.gov.tr. Retrieved on 12 August 2013.</ref>

In August 2013, tender for the 126 driverless train units for the [[M5 (Istanbul Metro)|M5]] line was won by CAF and [[Mitsubishi Motors|Mitsubishi]] with 119 million euros.<ref>https://rayhaber.com/2013/08/126-adet-metro-alimi-ihalesi-icin-en-iyi-teklif-veren-firma-mitsibushi-oldu/ Retrieved on 1 August 2013.</ref> The first units were delivered in November 2016.<ref>https://rayhaber.com/2016/11/uskudar-cekmekoy-metro-hattinin-yeni-vagonlari-raylara-indi/ Retrieved on 23 November 2016.</ref>

In March 2016, [[EUROTEM|Eurotem]] signed a contract to supply 300 driverless units for the [[M7 (Istanbul Metro)|M7]] line, amounting to 280.200.000 euros.<ref name=":1">https://rayhaber.com/2016/03/kabatas-mecidiyekoy-mahmutbey-rayli-ulasim-sistemi-icin-arac-alimi-ihalesini-kazanan-firma-belli-oldu/ Retrieved on 3 March 2016.</ref>

=== Rolling stocks by line ===

==== M1A and M1B ====
Although line M1 is a (light) metro line, its rolling stock—in use since 1989—is made up of typical [[ABB Group|ABB]] light rail vehicles (LRVs). These are partly the same as those used on the [[T4 (Istanbul Tram)|T4 tramway line]]. The rolling stock of the line is planned to be refurbished and made driverless.<ref>{{Cite web |last=Uysal |first=Onur |date=2019-01-16 |title=İstanbul'da hangi metrolar sürücüsüz olacak? |url=https://tr.railturkey.org/2019/01/16/istanbulda-hangi-metrolar-surucusuz-olacak/ |access-date=2023-07-29 |website=Rail Turkey Tr |language=tr-TR}}</ref><ref name=":0">{{Cite book |url=https://www.metro.istanbul/Content/assets/uploaded/Genel-Tan%C4%B1t%C4%B1m_Katalogu-2021.pdf |title=Genel Tanıtım Kataloğu |publisher=[[Metro Istanbul]] |year=2021 |pages=4}}</ref>

==== M2 and M6 ====
The rolling stock on the M2 and M6 lines, which totals a number of 192 units,<ref name=":0"/> is made up of [[Alstom]] vehicles from France and [[Hyundai Rotem]] vehicles from [[South Korea]] which are manufactured in [[Adapazarı]] by [[Eurotem]]. All wagons have 8 double doors, making them have 4 openings on each side per wagon, the rolling stock also includes a fast passenger change, heating, air conditioning and broadcasting system. These lines are the only lines to use third rail power.

</gallery>

==== M3 and M9 ====

The rolling stock on the M3 line, consists of 68 [[Alstom Metropolis]] AM4 (similar-looking vehicles are used at M4 [[Budapest Metro]]) units. Some of them are also used on the M9 Ataköy-Olimpiyat metro line.

==== M4 ====
Line M4 uses CAF rolling stock. Trains operate in 4-car sets and can couple to form 8-car trains.

==== M5 ====
Line M5 uses driverless 6-car CAF rolling stock.

==== M7 and M8 ====
Line M7 uses driverless Hyundai Rotem rolling stock.<ref name=":1" /> Trains are made of 4-car units and can couple to form 8-car trains, although these are not currently used. Line M8 uses very similar trains, but only as 4-car sets.

==== M11 ====
Line M11 uses CRRC rolling stock.

== Future extensions ==
As part of the Istanbul Metropolitan Municipality goal of expanding the size of the city rail transportation network to {{cvt|630|km||abbr=}} by 2030,<ref>{{Cite web|url=https://www.ebrd.com/news/2017/ebrd-cofinances-groundbreaking-istanbul-metro.html|title=EBRD co-finances the Istanbul Metro expansion|website=ebrd.com|access-date=12 February 2019}}</ref> 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.
 
Due to the city's unique geography and depth of the Bosporus which divides the city, none of the current Istanbul Metro lines cross the strait; 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 {{convert|30.2|km|mi|abbr=on}} line that would link [[İncirli]] with [[Kadıköy|Söğütlüçeşme]] via a tunnel under the Bosphorus also designed to accommodate road traffic.<ref>{{cite web|url=https://www.railwaygazette.com/projects-and-planning/istanbul-plans-cross-bosporus-metro-line/48407.article|title=Istanbul plans cross-Bosporus metro line|website=[[Railway Gazette International]]|date=23 April 2019|access-date=8 September 2020}}</ref>

The following metro lines are under construction:
