Istanbul Metro

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. 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 platform next to the rail line, while the distance between stations varied from . 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 to withstand an earthquake of up to 9.0 on the Richter magnitude scale. entered service in 2014. The first section between Taksim and 4. Levent entered service, after some delays, on 16 September 2000. This line is 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. Eurotem will build a total of 92 new trainsets for the M2 line. As of 30 January 2009, a total of 34 trainsets, each with 4 cars, were being used on the M2 line. On 2 September 2010, the northern (temporary) terminus of Darüşşafaka followed up. The southern extension of the M2 line from Taksim to Yenikapı, across the Golden Horn with Haliç station on the bridge and underground through the historic peninsula, entered service on 15 February 2014. The Taksim-Yenikapı extension is long, with four stations. The total cost of the extension was $593 million. At Yenikapı, it will intersect with the extended M1 line and the Marmaray commuter line, which since its opening in 2013 has offered a connection between the Asian and European sides of the city. The trip between the Şişhane station in Beyoğlu and the Haciosman station in Maslak is long and takes 27 minutes; including Şişhane - Taksim (, 2 minutes), Taksim - 4. Levent (, 12 minutes), and 4. Levent - Haciosman (, 12 minutes.) The total length of the European side of the M2 line will reach when all 16 stations from Hacıosman to Yenikapı will be completed; not including the -long Golden Horn Metro Bridge, the long Taksim-Kabataş tunnel connection with the Seabus port, and the long Yenikapı-Aksaray tunnel connecting the M1 line to the Yenikapı Transfer Center. The first section opened on 17 August 2012, terminating in Kartal. Construction of the long M5 line from Üsküdar via Ümraniye to Çekmeköy started in March 2012. ==Operations==

metro station on the M5 line The Metro operates from 06:00 AM to 12 AM every 6–12 minutes, except for the M8 line, which temporarily operates from 06:00 AM to 23:00 PM. During peak hours, the intervals could be reduced to 3 to 4 minutes. The metro has a flat fare of 40 TL, a student rate of 20.08 TL, and a fare of 25.06 TL for teachers and senior residents, when used with the Istanbulkart, the city's universal contactless payment card. Night operations On 30 August 2019 as a gesture for the Victory Day of Turkey, Mayor of Istanbul, Ekrem İmamoğlu, announced that many lines of Istanbul were going to provide 24 hours service during the weekends with trains at 20 minutes interval. Since August 2019, the Istanbul Metro started to provide 24 hours service for some lines on weekends and public holidays, but this service was discontinued in March 2020 due to coronavirus pandemic. On 5 March 2022 Metro Istanbul announced that the night metro service would be re-started on the following lines: M1A Yenikapı-Atatürk Airport, M1B Yenikapı-Kirazli, M2 Yenikapı-Hacıosman, M4 Kadıköy-Sabiha Gökçen Airport, M5 Üsküdar-Çekmeköy, and M6 Levent-Boğaziçi University/Hisarüstü, and later added M7 Mecidiyeköy-Mahmutbey on 14 July 2022. ==Lines==

Each line is given a different color and name. The letter "M" stands for metro, while "T" stands for tram, "F" stands for funicular, "TF" stands for cable car and "B" for suburban. Frutiger LT Pro is used as the font for the icons.

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. Entrances are usually built into sidewalks along a street, although many stations of newer lines have their entrances from street level on small plazas. 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 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, 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 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 and can accommodate trains up to 4 cars long. Platforms on the M2, M3, M4, M7 and M11 lines span about 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 platforms 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 on the M1 line, Yenikapı and Sanayi on the M2 line, Olimpiyat on the M9 line, and 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 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).

This table lists technical characteristics of the metro lines that are currently in service or under construction. ==Alignment and interchanges==

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. 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 Istanbul such as Bostancı, Kadıköy, Bakırköy and Kabataş. The M3 line has an interchange with the M9 line at the İkitelli Sanayi station, M7 line at Mahmutbey station, M1 line at Kirazlı station, M2, M1 and Metrobus at 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 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 Üsküdar station. At Altunizade the line has a Metrobus interchange. It has an interchange with the M8 line at Dudullu station. 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 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 at Ikitelli station, with the M1A line at Yenibosna station and Marmaray (B1) at Ataköy station. The M11 line interchanges with the M2 line and Metrobus at Gayrettepe station, and with the M7 line at Kağıthane station. ==Rolling stock==

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. History 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. Today the system has 268 trains. In September 2009, CAF signed a contract to supply 144 units for the 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. In August 2013, tender for the 126 driverless train units for the M5 line was won by CAF and Mitsubishi with 119 million euros. The first units were delivered in November 2016. In March 2016, Eurotem signed a contract to supply 300 driverless units for the M7 line, amounting to 280.200.000 euros. 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 light rail vehicles (LRVs). These are partly the same as those used on the T4 tramway line. The rolling stock of the line is planned to be refurbished and made driverless. M2 and M6 The rolling stock on the M2 and M6 lines, which totals a number of 192 units, 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.

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. 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 by 2030, 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 line that would link İncirli with Söğütlüçeşme via a tunnel under the Bosphorus also designed to accommodate road traffic. The following metro lines are under construction: Construction of the following metro lines are planned or on hold: European side M7 metro line extension The M7 Kabataş-Yıldız metro line extension is under construction. The extension will have 2 new stations and is expected to go into service in 2028. It will interconnect with ferries at Beşiktaş and Kabataş stations, with T1 trams line at Kabataş station and with F1 funicular line at Kabataş station. It will also extend 5 stations west to Hastane, expected to go into service in 2028. Due to planning adjustments, a further extension from Hastane to Esenyurt Meydan has not started yet. M11 Metro Line The M11 Gayrettepe-Arnavutköy Hastane metro extension to Halkalı is under construction. The extension from Arnavutköy Hastane to Halkalı will be opened in second quarter of 2026. Asian side ;M4 metro line M4 Kadıköy–İçmeler Metro Line is extending to İçmeler. Planned opening date of Kaynarca Merkez is early 2027.
