They carry many people. Some lines are on one side of the water. Some lines are on the other side. The city is split by a deep strait. This means the two parts do not touch. A special rail line links them together. There are many stations for people to use. Some new stations are being built now. It is a very big system.

The Istanbul Metro is a huge train system.

It helps people travel across the city of Istanbul. The city is split by a deep body of water. This water is called the Bosporus strait. Because of this, the metro lines do not touch. Most lines stay on one side or the other. Eight lines run on the European side. Three lines run on the Asian side.

To cross the water, people use the Marmaray rail line. This line connects the two sides in many places.

The system is very large. It has 160 stations in use.

Workers are building 36 more stations right now. The metro is the 21st longest system in the world. It is also the 4th longest in Europe. The oldest part is the M1 line. It opened on 3 September 1989. Some lines, like the M5, are fully automated. This means they can run without a driver. People use a special card to pay for rides. This card is called the Istanbulkart.

It helps millions of people move through the city every day. This system is very large and impressive. As of 2024, it is the 21st longest metro in the world. It also holds the title of the 4th longest in Europe.

The network covers 243.3 kilometers of track. Currently, there are 160 stations in service. Workers are also building 36 more stations right now.

How the system works depends on the city's unique geography. Istanbul is split by the Bosporus, a deep strait of water.

Because of this water, the metro lines do not connect directly. Eight lines stay on the European side of the city. Three lines run on the Asian side.

To link the two sides, people use the Marmaray commuter rail. This rail connects to the metro in several places. This way, travelers can still cross from Europe to Asia.

People have dreamed of a metro in Istanbul for a long time.

The oldest underground rail is the Tünel, which opened in 1875. This was the first underground line in continental Europe. Much later, a French engineer named L. Guerby made a plan in 1912. He imagined 24 stations between Topkapı and Şişli. Other planners like Henri Prost and Marc Langevin made more plans. However, these ideas did not happen for many years. The modern system finally began construction in 1989.

Building the tracks was a very big job for engineers.

They used a method called cut-and-cover to build the lines. This method helps the tracks stay safe during an earthquake. The system is built to withstand a 9.0 magnitude quake.

On the M2 line, workers found many old archaeological sites. These historical sites were found while drilling into the ground. This discovery slowed down the work for many stations. The M1 line was first called the "light metro." It uses shorter trains and shorter platforms than usual.

Today, the metro is a busy part of daily life. Most lines run from 06:00 AM until midnight. Some lines, like the M5, are fully automated. This means they can run without a human driver. Passengers use a special card called the Istanbulkart to pay. The fare for a ride is 40 TL. Students can pay a lower rate of 20.08 TL. Some lines even offer service 24 hours a day on weekends. This makes traveling through the huge city much easier for everyone.

The Istanbul Metro is a massive rapid transit railway network serving Istanbul, Turkey.

It serves as a vital artery for the city's movement. As of 2024, the system spans 243.3 kilometers of track. This makes it the 21st longest metro system in the world. It also ranks as the 4th longest system in Europe. The network includes 160 stations currently in service. Workers are also actively building 36 more stations.

The system is operated by Metro Istanbul, a public enterprise. This company is controlled by the Istanbul Metropolitan Municipality. One exception is the M11 line, which is operated by TCDD Taşımacılık.

The system's design must account for Istanbul's unique geography. The city is divided by the Bosporus, a deep strait of water.

Because of this water, the European and Asian networks do not connect directly. There are eleven lines in total. Eight lines are located on the European side of the Bosporus. These include the M1A, M1B, M2, M3, M6, M7, M9, and M11 lines. Three lines serve the Asian side. These are the M4, M5, and M8 lines. To cross between continents, passengers use the Marmaray commuter rail. This rail connects to the metro network in several specific locations.

Engineers used specific methods to ensure the system is safe and durable. They used the cut-and-cover method to build the network. This method helps the structures withstand significant seismic activity. The entire network is built to survive an earthquake of up to 9.0 on the Richter magnitude scale. Building the M2 line presented unique challenges for workers. During the drilling process, crews discovered many archaeological sites. These ancient historical sites slowed or stopped construction for many stations, particularly in the south.

This shows how modern transit must sometimes wait for history.

Istanbul has a very long history of underground rail. The Tünel is the oldest underground urban rail line in the city. It entered service on 17 January 1875. It is the world's second-oldest underground urban rail line. It was also the first underground urban rail line in continental Europe. Although it is a funicular, it paved the way for future plans. In 1912, a French engineer named L. Guerby proposed the first master plan. His plan, titled Avant Projet d'un Métropolitain à Constantinople, included 24 stations. Other planners like Henri Prost and Marc Langevin also proposed networks later. However, the modern mass transit system did not begin until 1989.

The M1 line was the first modern section to open. It began service on 3 September 1989. It was originally called "Hafif Metro," which means "light metro." This name came from its design. The M1 line uses shorter trainsets and shorter station platforms than a traditional metro.

The line was later extended to reach Atatürk Airport in 2002. The M2 line began construction on 11 September 1992. A major section of the M2 opened on 16 September 2000. This line connects Taksim to Hacıosman. It even includes a station on the Golden Horn Metro Bridge.

The Taksim-Yenikapı extension cost $593 million to complete.

Different lines have different technical capabilities and speeds. The M11 line is quite different from the others. It has a higher maximum speed of 120 km/h. It uses trains similar to Chinese metro type B trains.

Some lines are also fully automated. This means they operate without a driver. The M5 and M7 lines are examples of these automated systems. The M6 line is known as the "Mini-Metro." It is a light metro line with a single track between stations. Most lines operate from 06:00 AM to 12:00 AM. However, some lines provide 24-hour service on weekends and public holidays.

Daily travel on the metro is managed through a specific payment system. Passengers use the Istanbulkart, which is a universal contactless payment card. The standard flat fare is 40 TL. There are discounted rates for specific groups. Students pay 20.08 TL per ride. Teachers and senior residents pay 25.06 TL. The metro connects to many other transit types. This includes the Istanbul Tram, Metrobüs, and various cable cars. It also links to the F1, F2, F3, and F4 funicular lines. This creates a massive, interconnected web for the entire city.
