The State Railways of the Republic of Turkey (Turkish: Türkiye Cumhuriyeti Devlet Demiryolları), abbreviated as TCDD, is a government-owned national railway company responsible with the ownership and maintenance of railway infrastructure in Turkey, as well as the planning and construction of new lines. TCDD was formed on 4 June 1929 as part of the nationalisation of railways in Turkey.
The Turkish State Railways own and maintain all public railways in Turkey. This includes railway stations, ports, bridges and tunnels, yards and maintenance facilities. In 2016, TCDD controlled an active network of of railways, making it the 22nd-largest railway system in the world. Apart from railway infrastructure, TCDD also owns several rail transport companies within Turkey as well as a 50% share of the İzmir-area commuter rail system, İZBAN.
Prior to 2017, TCDD also operated all railways in Turkey. However, with the government taking steps to privatise some of the Turkish railway network, TCDD Taşımacılık was formed on 14 June 2016 to take over all railway operations. Handover of rolling stock was signed on 28 December of the same year and TCDD formally ceased all railway operations on 31 December 2016.
See main article: History of rail transport in Turkey.
After World War I and the Turkish Independence War, the Republic of Turkey was a new-formed country. Even though Turkey had a railway network, most of it was operated by foreign companies. The State Railways of the Republic of Turkey (TCDD) was formed on 31 May 1927. TCDD took over the Chemin de fer d'Anatolie-Baghdad, a holding company formed in 1924 by Turkey to take over some rail lines in Turkey, on 1 June 1927 and had control over the tracks of the former Anatolian Railway (CFOA) and the Transcaucasus Railway line in Turkish borders. TCDD now had rail lines to the cities Istanbul, İzmit, Ankara, Afyon, Adapazarı and Konya. On 1 January 1929, TCDD took over the rail line from Mersin to Adana (formerly the Mersin-Tarsus-Adana Railway). Apart from taking over already built lines, TCDD needed to build more line because many important cities were still not serviced by rail. In 1926, TCDD started to build a rail line east to Sivas, reaching Kayseri in 1927 and Sivas in 1930. TCDD continued to acquire from the other rail companies; taking over the Mudanya-Bursa Railway in 1931, the Smyrna Cassaba Railway in 1934, the Ottoman Railway Company in 1935 and the Oriental Railway in 1937. With most of the railways in Turkey under TCDD control, TCDD connected lines such as Kütahya with Balıkesir in 1932 and the former SCP line in Afyon with the former CFOA line. In 1932 TCDD completed the railway to Samsun heading north at Sivas. TCDD continued to build lines, reaching Zonguldak, Erzurum, Erzincan, Diyarbakır and Elazığ in the following years. World War II broke out in 1938, slowing down the building. Between 1938 and 1996 TCDD building decreased. The railway only extended to Gaziantep (1955) and Van (1962).
In 1948 the State Railways released a plan of railway lines that were to be constructed to "ensure national progression and safety".[1] The plan included 5538km (3,441miles) of new railway lines of which only 96km (60miles) were actually completed; the Gaziantep-Karkamış section of the Narlı-Nusaybin railway was completed in 1960.[2]

The Turkish State Railways operate most trains in the country. Intercity, regional, suburban, freight and most industrial lines are owned and operated by the State Railways. The only other railways in Turkey include İZBAN (TCDD holds 50% of the company's shares) which operates commuter rail service around İzmir and a few other industrial railways. In addition to rail services, TCDD has been responsible since 1927 for operating several major ports which handle 30% of Turkish port activities.[5]
The Turkish State Railways operate passenger services on 90% of their system. These are intercity, regional, commuter and international services. In the railways first year 52% of passenger travel in Turkey was by rail, despite the system lacking connections to many parts of the country. Rail transport was the main mode of transport for passengers in the following two decades, reaching an all-time high of 57% of passenger transport in 1947, but then started to decline after 1950, due to the mass construction of roads.[6] Today, the passenger ratio is slowly increasing with the opening of high-speed rail lines in Turkey.
In 2019, almost 150 million people traveled by train in Turkey. 17.5 million on main lines, 8.3 million on high speed lines (2% increase compared to 2018) and 124 million used the Marmaray commuter railway.[7] The share of railway in domestic travels in 2013 is about 2.2%.[8]
The types of passenger service are:
See main article: High-speed rail in Turkey.
High-speed rail in Türkiye began service in 2009. TCDD has branded its high-speed service as Yüksek Hızlı Tren or YHT, directly translating to High-Speed Train, dubbed after the trains' capacity to reach 250 km/h (and in some advanced sections of the Ankara-Konya railroad up to 300 km/h). There had been previously tried but failed accelerated train projects, i.e. higher speed rail without the necessary upgrades on the railroad tracks, causing a number of accidents and ending up with losses incurred by TCDD in early 2000s. YHT, in stark contrast, became a commercially successful, safe and cheap alternative to Flights and Roads, cutting the travel time between the city centers of two largest cities of the country up to 4 hours. Currently, YHT trains operate 22 daily trips based from its central hub in Ankara, in addition to more trips on the Istanbul–Konya high-speed railway that bypass Ankara.
YHT currently operates on two main lines: the Ankara–Istanbul high-speed railway, and Ankara–Konya high-speed railway. In total, these lines connect 8 provincial capitals out of 81 Provinces in Türkiye, namely Adapazarı (via Arifli), Ankara, Bilecik, Eskişehir, Istanbul, İzmit, Karaman and Konya. There are currently ongoing construction projects aiming to link up at least 6 more provincial capitals, including third and fourth largest cities of the country İzmir and Bursa, besides Afyonkarahisar, Edirne, Kayseri, Sivas and other potential cities. Further ambitions at the planning stage eventually aim to link up East and West points of the country through high-speed railways and act as an international High-speed railway bridge across Europe and Asia
On 13 March 2009, the first phase of the Ankara–Istanbul high-speed railway entered service between Ankara and Eskişehir. On 25 July 2014, the Ankara-Istanbul high-speed line services began to reach the Pendik railway station on the Asian side of Istanbul,[9] and on 13 March 2019 the services began to reach the Halkalı railway station on the European side of Istanbul, passing through the Marmaray railway tunnel under the Bosphorus strait. There were initially 6 daily departures in both directions.[10] The high-speed line between Ankara and Istanbul has reduced the overland travel time to hours, compared to 5 hours by car.
On 23 August 2011, the YHT service on the Ankara–Konya high-speed railway was inaugurated. The Konya-Ankara line was later connected with the Istanbul–Ankara line at the Polatlı district of Ankara Province on 23 March 2013, essentially bypassing the city of Ankara and shortening the distance from Istanbul to Konya to 5 hours. Most recently on 8 January 2022, the Konya line was extended into another provincial capital Karaman.
High-speed rail in Turkey is still developing, with new lines currently under construction or in the planning phase. By 2023, the Ministry of Transport and Infrastructure expects Turkey's high-speed rail system to increase to 10,000 kilometers.[11]
Mainline service (Turkish: Anahat) is the railway's main service. In 2010 mainline services made up for 24% of the railways passenger traffic.[12] Mainline service includes 2 types of trains: Express and Blue Train.
Express service is between major cities and are fast, comfortable and equipped with modern air conditioned TVS2000 railcars and only stop at important stations. Express trains have an average operating speed of 100km/h to 120km/h. Express service has both day (e.g. İzmir-Bandırma) and overnight trains between major cities far apart (e.g. Ankara-Kars). These trains have coaches, a dining car and a sleeping car or a couchette car or sometimes both.
The TVS2000 railcars used on mainline service are the most comfortable cars in TCDD's entire fleet. TVS2000 railcars may also be used on International services because international services are considered mainline services within Turkey.

See also: Haydarpaşa Terminal.
The Haydarpaşa Terminal was the terminus for a weekly train, to Tehran in Iran, another train to Iran used to travel between Van, Turkey and Tebriz in Iran.[13]
Additionally, trains from Iran to Syria (and vice versa) used to pass through Turkey.[13]
As of 2011, the Turkish State Railways operate commuter rail in Istanbul and Ankara, with previous commuter service in İzmir from up to 2006, which is now operated by İZBAN. The railways use the E14000 and the E23000 EMUs on their commuter services. Previously, the newly retired E8000 EMUs and the E4000 electric locomotives were used as well. The first commuter rail service in Turkey was the Istanbul-Halkalı Line on the European side of Istanbul, operating from Sirkeci Terminal to Halkalı in 1955.[17] [18] [19]
From 1980 onwards, rail freight tonne-kilometers transported by the TCDD rose slightly from ≈5000million tonne-km in 1980 to ≈7000million tonne-km in 1990 and to ≈9000million tonne-km in 2000.[20] Approximately 50% of freight moved is minerals or ores, with construction materials increasing to ≈10% in 2000 from less than 5% in 1980, food/agricultural products, chemicals/petroleum, and metal sectors each account for between 5 and 10%. International freight accounted for approximately 5% of totals in 2000.[20]
As of 2012, 25.7 million ton is transported by rail in Turkey. Two steel companies, Erdemir and Kardemir, top 2 customers of TCDD, had transported 4.5 million ton in 2012, mainly iron ore and coal.[21] 2.1 million tons of rail freight belong to international traffic. Most of international traffic is between Turkey and Europe, done via Kapikule. Several container trains are running in this route as well as conventional wagons.[22]
As of 2014, 26.6 million ton is transported on rail in Turkey. 7.1 million of it is done by private wagons. International transport went down to 1.7 million.[23]
Containers are widely used both in international and domestic transportation. 7.6 million ton is carried in containers. TCDD is supporting transportation by containers. Thus almost all of the private railway companies invested in container wagons, and carrying 20% of all rail freight by their own wagons.[24]
TCDD has plans to strengthen freight traffic by adding 4000 km conventional lines until 2023. That includes new international rail connections to Georgia, Iraq and Iran.[25] TCDD is also constructing 18 logistic centers to enable transportation of more loads by rail.[26]
TCDD is planning to increase its transit traffic (11000 to in 2011) by constructing "iron silk road" to connect Europe to Asia. Marmaray is the most important part of this project which was completed in 2015 and now in service.[27] Another project is Kars–Tbilisi–Baku railway which is planned to be completed in 2016 and start functioning in 2017.[28] Also, plans for another supplying project to Kars-Tbilisi-Baku railway, the Kars-Igdir-Nakhcivan high speed railway has been completed.[29] TCDD wants to have share from the freight traffic between Europe and China through this line.[30]
The State Railways own and operate seven ports throughout the country and has connections to two more ports. The ports TCDD owns are the Port of Haydarpaşa[31] in Istanbul on the southern mouth of the Bosphorus, the Port of Izmir[32] on the Aegean Sea, the Port of Mersin[33] and the Port of İskenderun[34] on the Mediterranean Sea, the Port of Bandırma[35] on the Sea of Marmara, the Port of Derince[36] on the Gulf of İzmit, and the Port of Samsun on the Black Sea. The railways have connections to the Port of Zonguldak,[37] owned by Türkiye Taşkömürü Kurumu (Turkish Coal Company), the Port of Tekkeköy and the Port of Tekirdağ,[38] owned by AKPORT AŞ. In 2004, the privatization of all ports except Haydarpaşa began.
By 2014 Mersin, Iskenderun, Bandirma, Samsun ports are privatized.[39] Tender for privatization of Derince Port has also completed and waiting for takeover.[40]
The state railways are planning on building rail connections to the Port of Güllük[41] (via Çine) and to the Port of Ereğli, which TCDD serviced until 2004.
The ports TCDD owns are the most important in Turkey. The country's five largest ports are owned by the state railways. The Port of Haydarpaşa will soon be decommissioned, when the Marmaray project is complete.
Since 1950, the railway system's market share of freight transportation dropped from 70% to ≈55% (1960), ≈25% (1970), ≈10% (1980, 1990) and to less than 10% in 2000. A similar trend was observed in the percentage of passenger transport performed by rail – dropping from a share of greater than 40% in 1950 to ≈25% in 1960; less than 10% in 1970; ≈5% by 1980; and reaching an all-time low of 2% by 2000.[42] This was partly due to major investment and expansion in the road network.
The TCDD receives subsidies from the government for socially necessary operations, but has registered increasing losses in all its areas of business except for port operations; which have high port tariffs (higher than 36%).[42] By 2000, the cost to the Turkish government had exceeded $500 million per year in addition to a subsidy of over $100 million.[42] In addition to the problems caused by the lack of investment from 1950 onwards, the TCDD organisation has been characterised as suffering from the common problems associated with state-owned enterprises; i.e. emphasis on production rather than customer needs; subject to government reliance and interference; and an inward-looking corporate culture.[42]
As of 2008, the amount of freight transported was the highest ever (18.343 million tonne-kilometers); though actual growth was small over the previous 10 years, and passenger figures had risen slightly overall over the past decade.[43]
As of 2008, the TCDD administers the Ankara Railway Factory, Sivas Concrete Sleeper factory, Afyon Concrete Sleeper factory, Behiçbey rail welding and track machinery repair factory and Çankırı Switch factory. Additionally, the state owned companies TÜLOMSAŞ, Turkish: TÜDEMSAŞ and TÜVASAŞ are affiliates. The TCDD has a 50% share in the Turkish: İzmir Banliyö Taşımacılığı Sistemi A.Ş. (İZBAN A.Ş.) which operates the metro in İzmir, and a 15% share in EUROTEM.[43]

TCDD directly owns and operates 8697km (5,404miles) of common carrier lines, of which 1920km (1,190miles) are electrified, throughout 57 provinces.[52] Along with this, the railways own and operate over 240km (150miles) of industrial lines and 206km (128miles) of high-speed lines, with 574km (357miles) of lines under construction.[53] As of 2010, the railways consist of 763 tunnels, 25,441 bridges, 17 wyes and 7 loops.[54] The railway's fleet consists of 467 main line Diesel locomotives, 67 Electric locomotives, 860 passenger coaches, 135 MUs, 33 High-speed rail sets and 15,384 freight cars.[55] TCDD also owns 3 rail ferries.
Turkey has chosen to electrify at the conventional 25 kV 50 Hz AC. The first electrified lines were the Istanbul suburban lines on the European side, from Sirkeci to Soğuksu, on 4 December 1955, and in the same period the E8000 electrical multiple units were taken into use. The suburban lines on the Asian side of Istanbul, from Haydarpaşa to Gebze, were electrified in 1969; while the Ankara suburban trains were electrified in 1972, on the line from Sincan to Kayaş.
On 6 February 1977 the tracks from Gebze to Adapazarı were made double track and electrified, allowing the first main line operation of electric trains in Turkey. The line from Arifiye outside Adapazarı to Eskişehir were further electrified in 1989 and in 1993 to Sincan, allowing electric train passages from Istanbul to Ankara. In 1994 the European lines from Istanbul to Edirne, Kapıkule and the Bulgarian border were also electrified. The same year the line from Divriği to İskenderun in eastern Turkey was also electrified, though this line is not connected to the rest of the electrified network. In 2006 the İzmir suburban system was also electrified.

These 18 logistic centers are:Halkali, Samsun-Gelemen, Usak (completed)Kosekoy-Izmit, Hasanbey-Eskisehir, Kaklik-Denizli, Bogazkopru-Kayseri (partially completed)Yesilbayır-Istanbul, Gökköy-Balikesir, Bozüyük-Bilecik, Kayacık-Konya, Yenice-Mersin, Sivas, Türkoğlu-Kahramanmaraş, Kars, Palandöken-Erzurum, Mardin (under construction)
TCDD owns and operates many facilities throughout Turkey. These facilities are; yards for storing freight and passenger cars, depots and locomotive shops for repair and maintenance and freight facilities for transferring or storing freight.
Güvercinlik Yard in central Ankara is the largest railway facility in Turkey. This multi-use facility includes a marshaling yard, passenger yard, 3 repair shops, for passenger cars, freight cars and locomotives, freight transfer terminal and a grain silo siding. The Haydarpaşa Yard is the second largest yard in Turkey, consisting of a freight yard, passenger yard, 3 maintenance shops for locomotives, passenger cars and freight cars, and a loop for trains.
The Turkish State Railways own and operate two rail train ferries and connects to three others.
The most famous of these would be the Bosphorus train ferry in Istanbul. This ferry connects Haydarpaşa, on the Asian side, with Sirkeci, on the European side. Demiryolu and Demiryolu II are the two ferries that operate on the route and are owned by TCDD.
By starting the project of Marmaray, TCDD ended the Bosphorus train ferry and announced an alternative ferry for the freight trains passing from Europe to Asia or vice versa: Tekirdağ-Derince Ferry. It's a private ferry named Erdemir working as a subcontractor of TCDD. Ferry did trials in 2012, and had started regular transportation at the end of 2013.[57] Ferry has 5 lines with 800-meter total length.
The other train ferry owned by TCDD would be the Lake Van ferry, connecting Tatvan and Van via Lake Van, Turkey's largest lake. This ferry is a part of the only railway connection between Turkey and Iran, and thereby between Europe and India. Van is the name of the ferry that operates on the route and is also fully owned by TCDD.[58]
Other train ferries:
The Turkish State Railways currently has many network extension and modernization projects planned. TCDD is seeing the largest investment since the 1930s and with these investments is constructing new lines, primarily high-speed lines.
In addition to 5000 km high-speed line, Turkish Ministry of Transportation announced the construction of 4000 km new conventional rail lines as a part of 2023 strategy.[25]
TCDD has also been renewing the existing lines, some to be electrified, signalized and/or made double tracked. The budget for renewals and infrastructure of existing lines is more than 1 billion TL in 2014.[60]
There are also commuter rail projects (renewal or new lines) like Marmaray, İzban, Başkentray or Gaziray that are completed.
