110-765: The State Railways of the Republic of Turkey ( Turkish : Türkiye Cumhuriyeti Devlet Demiryolları ), abbreviated as TCDD, is a government-owned national railway company responsible for the ownership and maintenance of railways 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 owns and maintains 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 12,532 km (7,787 mi) of railways, making it

220-686: 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. 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. Additionally, trains from Iran to Syria (and vice versa) used to pass through Turkey. As of 2011,

330-475: A form of consonant mutation whereby a voiced obstruent, such as /b d dʒ ɡ/ , is devoiced to [p t tʃ k] at the end of a word or before a consonant, but retains its voicing before a vowel. In loan words, the voiced equivalent of /k/ is /g/; in native words, it is /ğ/. This is analogous to languages such as German and Russian , but in the case of Turkish it only applies, as the above examples demonstrate, to stops and affricates, not to fricatives. The spelling

440-415: A negative suffix -me to the verb (the suffix comes after the stem but before the tense): Necla okula gitmedi ('Necla did not go to school'). In the case of a verbal sentence, an interrogative clitic mi is added after the verb and stands alone, for example Necla okula gitti mi? ('Did Necla go to school?'). In the case of a nominal sentence, then mi comes after the predicate but before

550-703: 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

660-753: A single person out of respect. Turkish is a member of the Oghuz group of the Turkic family. Other members include Azerbaijani , spoken in Azerbaijan and north-west Iran , Gagauz of Gagauzia , Qashqai of south Iran and the Turkmen of Turkmenistan . Historically the Turkic family was seen as a branch of the larger Altaic family, including Japanese , Korean , Mongolian and Tungusic , with various other language families proposed for inclusion by linguists. Altaic theory has fallen out of favour since

770-407: A verb in the form of the copula ol or y (variants of "be"). Examples of both are given below: The two groups of sentences have different ways of forming negation. A nominal sentence can be negated with the addition of the word değil . For example, the sentence above would become Necla öğretmen değil ('Necla is not a teacher'). However, the verbal sentence requires the addition of

880-828: Is a 76.6-kilometre-long (47.6 mi) commuter rail line located in Istanbul , Turkey . The line runs from Halkalı , on the European side , to Gebze , on the Asian side , along the north shore of the Sea of Marmara . Mostly using the right-of-way of two existing commuter rail lines, the Marmaray line linked the two lines via a tunnel under the Bosporus strait, becoming the first standard gauge rail connection between Europe and Asia (all prior connections ran through Russia and used

990-673: Is accessed via tunnels bored from Kazlıçeşme on the European side and Ayrılıkçeşmesi on the Asian side of Istanbul and represents the world's deepest undersea immersed tube tunnel. Fire-resistant concrete developed in Norway was essential for the safety of the project. Construction started in May 2004 and the Marmaray tunnel was completed on September 23, 2008, with a formal ceremony to mark its completion on October 13. The second phase of

1100-531: Is based on the dialect of Istanbul . This Istanbul Turkish ( İstanbul Türkçesi ) constitutes the model of written and spoken Turkish, as recommended by Ziya Gökalp , Ömer Seyfettin and others. Dialectal variation persists, in spite of the levelling influence of the standard used in mass media and in the Turkish education system since the 1930s. Academic researchers from Turkey often refer to Turkish dialects as ağız or şive , leading to an ambiguity with

1210-503: Is between Turkey and Europe, done via Kapikule . Several container trains are running in this route as well as conventional wagons. As of 2014, 26.6 million tons are transported on rail in Turkey. 7.1 million of it is done by private wagons. International transport went down to 1.7 million. Containers are widely used both in international and domestic transportation. 7.6 million tons are carried in containers. TCDD supports transportation by containers. Thus, almost all of

Each section weighs up to 18,000 tons. The tube was placed 60 metres (197 ft) below sea level, beneath 55 metres (180 ft) of water and 4.6 metres (15 ft 1 in) of earth. It

1540-573: Is in Ankara. 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. Turkish language To

1650-628: Is integrated with other parts of the Istanbul public transport network, including the Metro and the Metrobus network, via a number of interchanges. It is also integrated with the YHT high-speed train network to Ankara , Eskişehir and Konya , as well as with the international trains to Sofia in Bulgaria which depart from Halkalı. The project involved building a 13.6-kilometre (8.5 mi) tunnel under

1760-654: Is mutually intelligible with Azerbaijani . In particular, Turkish-speaking minorities exist in countries that formerly (in whole or part) belonged to the Ottoman Empire , such as Iraq, Bulgaria, Cyprus , Greece (primarily in Western Thrace ), the Republic of North Macedonia , Romania, and Serbia. More than two million Turkish speakers live in Germany; and there are significant Turkish-speaking communities in

1870-635: Is one of the official languages of Cyprus . Turkish has official status in 38 municipalities in Kosovo , including Mamusha, , two in the Republic of North Macedonia and in Kirkuk Governorate in Iraq. Cyprus has requested the European Union to add Turkish as an official language, as it is one of the two official languages of the country. In Turkey, the regulatory body for Turkish is

"Since AD 342, it has seen large earthquakes that each claimed more than 10,000 lives." Some scientists have estimated a 77% probability that, at some time in the next 30 years, Istanbul will suffer an earthquake measuring 7.0 or more on the Richter magnitude scale . The waterlogged, silty soil on which

2090-686: 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. The share of railway in domestic travels in 2013 is about 2.2%. The types of passenger service are: 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

2200-572: Is the most important part of this project which was completed in 2015 and now in service. Another project is Kars–Tbilisi–Baku railway which is planned to be completed in 2016 and start functioning in 2017. Also, plans for another supplying project to Kars-Tbilisi-Baku railway, the Kars-Igdir-Nakhcivan high-speed railway has been completed. TCDD wants to have share from the freight traffic between Europe and China through this line. The State Railways own and operated seven ports throughout

2310-642: Is usually made to match the sound. However, in a few cases, such as ad 'name' (dative ada ), the underlying form is retained in the spelling (cf. at 'horse', dative ata ). Other exceptions are od 'fire' vs. ot 'herb', sac 'sheet metal', saç 'hair'. Most loanwords, such as kitap above, are spelled as pronounced, but a few such as hac 'hajj', şad 'happy', and yad 'strange' or 'stranger' also show their underlying forms. Native nouns of two or more syllables that end in /k/ in dictionary form are nearly all /ğ/ in underlying form. However, most verbs and monosyllabic nouns are underlyingly /k/. The vowels of

It never occurs at the beginning of a word or a syllable, but always follows a vowel. When word-final or preceding another consonant, it lengthens

2530-527: 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, rolling stock and operations were handed over to TCDD Transport and TCDD formally ceased all railway operations on 31 December 2016. After World War I and

2640-713: The Aegean region, with its usage extending to Antalya . The nomadic Yörüks of the Mediterranean Region of Turkey also have their own dialect of Turkish. This group is not to be confused with the Yuruk nomads of Macedonia, Greece, and European Turkey, who speak Balkan Gagauz Turkish . The Meskhetian Turks who live in Kazakhstan, Azerbaijan and Russia as well as in several Central Asian countries, also speak an Eastern Anatolian dialect of Turkish, originating in

The contract for the project was awarded to a Japanese-Turkish consortium led by Taisei Corporation in July 2004. The consortium included Gama Endustri Tesisleri Imalat ve Montaj and Nurol Construction . The Bosphorus (Istanbul Strait)

2860-769: The European Investment Bank (EBI) provided much of the financing for the project. By April 2006, the JICA had lent 111 billion yen and the EIB 1.05 billion euro for the work. The original cost was estimated at $ 4.5 billion although it finally cost almost twice that. The Marmaray uses TCDD E32000 rolling stock manufactured by Hyundai Rotem in ten- and five-car EMU configurations. The original €580 million contract called for 440 vehicles to be produced locally by Eurotem , Hyundai Rotem's joint venture with Turkish rolling stock manufacturer TÜVASAŞ . Hyundai Rotem

2970-631: The Germanic runic alphabets . With the Turkic expansion during Early Middle Ages ( c.  6th –11th centuries), peoples speaking Turkic languages spread across Central Asia , covering a vast geographical region stretching from Siberia all the way to Europe and the Mediterranean . The Seljuqs of the Oghuz Turks , in particular, brought their language, Oghuz —the direct ancestor of today's Turkish language—into Anatolia during

It is the literary standard for the Karamanlides . At least one source claims Turkish consonants are laryngeally-specified three-way fortis-lenis (aspirated/neutral/voiced) like Armenian, although only syllable-finally. The phoneme that

3190-437: The Ottoman Empire period ( c.  1299 –1922) is termed Ottoman Turkish , which was a mixture of Turkish, Persian, and Arabic that differed considerably and was largely unintelligible to the period's everyday Turkish. The everyday Turkish, known as kaba Türkçe or "vulgar Turkish", spoken by the less-educated lower and also rural members of society, contained a higher percentage of native vocabulary and served as basis for

3300-615: The Seljuq Turks , who are both regarded as the ethnic and cultural ancestors of the Ottomans , the administrative language of these states acquired a large collection of loanwords from Arabic and Persian . Turkish literature during the Ottoman period, particularly Divan poetry , was heavily influenced by Persian, including the adoption of poetic meters and a great quantity of imported words. The literary and official language during

3410-539: The Trabzon region of northeastern Turkey follows the reduced vowel harmony of Old Anatolian Turkish , with the additional complication of two missing vowels (ü and ı), thus there is no palatal harmony . It is likely that elün meant "your hand" in Old Anatolian. While the 2nd person singular possessive would vary between back and front vowel, -ün or -un, as in elün for "your hand" and kitabun for "your book",

3520-551: 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

3630-590: The Turkish Language Association ( Türk Dil Kurumu or TDK), which was founded in 1932 under the name Türk Dili Tetkik Cemiyeti ("Society for Research on the Turkish Language"). The Turkish Language Association was influenced by the ideology of linguistic purism : indeed one of its primary tasks was the replacement of loanwords and of foreign grammatical constructions with equivalents of Turkish origin. These changes, together with

Also during the 11th century, an early linguist of the Turkic languages, Mahmud al-Kashgari from the Kara-Khanid Khanate , published the first comprehensive Turkic language dictionary and map of the geographical distribution of Turkic speakers in the Dīwān Lughāt al-Turk ( ديوان لغات الترك ). Following the adoption of Islam around the year 950 by the Kara-Khanid Khanate and

3850-411: The 1940s tend to use the older terms of Arabic or Persian origin, the younger generations favor new expressions. It is considered particularly ironic that Atatürk himself, in his lengthy speech to the new Parliament in 1927, used the formal style of Ottoman Turkish that had been common at the time amongst statesmen and the educated strata of society in the setting of formal speeches and documents. After

3960-457: The 1960s, and a majority of linguists now consider Turkic languages to be unrelated to any other language family, though the Altaic hypothesis still has a small degree of support from individual linguists. The nineteenth-century Ural-Altaic theory, which grouped Turkish with Finnish , Hungarian and Altaic languages, is considered even less plausible in light of Altaic's rejection. The theory

4070-436: 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

4180-597: The Ankara-Istanbul high-speed line services began to reach the Pendik railway station on the Asian side of Istanbul, 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. The high-speed line between Ankara and Istanbul has reduced

4290-708: The Dutch Turkish company in charge of the project is required by the UK to be supplied by British suppliers. Mehmet Şimşek , Turkish finance minister said the project is meant to improve the connectivity of Turkey and upgrades Turkey's historic south trade route. The high speed rail is supposed to reach 225km/h, to reach this Railway Supply said Turkey will have to indtroduce modern modifications of its trasnport system and update train engines. The Turkish trasnporation ministry said eight carriages are supposed to commence passenger transportation in 2025. Almost 1500 km of track

4400-459: 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. The following is a list of railway border crossings of Turkey . TCDD

4510-906: The European side of Istanbul, operating from Sirkeci Terminal to Halkalı in 1955. 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. 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. As of 2012, 25.7 million tons are transported by rail in Turkey. Two steel companies, Erdemir and Kardemir, top 2 customers of TCDD, had transported 4.5 million tons in 2012, mainly iron ore and coal. 2.1 million tons of rail freight belong to international traffic. Most of international traffic

Some words restored from Old Turkic have taken on specialized meanings; for example betik (originally meaning "book") is now used to mean " script " in computer science . Some examples of modern Turkish words and the old loanwords are: Turkish is natively spoken by the Turkish people in Turkey and by the Turkish diaspora in some 30 other countries. The Turkish language

By 2023, the Ministry of Transport and Infrastructure expects Turkey's high-speed rail system to increase to 10,000 kilometers. Mainline service ( Turkish : Anahat ) is the railway's main service. In 2010 mainline services made up for 24% of

4950-527: The Latin alphabet for speakers of eastern dialects. Some immigrants to Turkey from Rumelia speak Rumelian Turkish , which includes the distinct dialects of Ludogorie , Dinler, and Adakale, which show the influence of the theorized Balkan sprachbund . Kıbrıs Türkçesi is the name for Cypriot Turkish and is spoken by the Turkish Cypriots . Edirne is the dialect of Edirne . Ege is spoken in

5060-567: The Latin script, encoded for many of the dialectal variations between Turkish dialects, the modern Latin script fails to do this. Examples of this are the presence of the nasal velar sound [ŋ] in certain eastern dialects of Turkish which was represented by the Ottoman letter /ڭ/ but that was merged into /n/ in the Latin script. Additionally are letters such as /خ/, /ق/, /غ/ which make the sounds [ɣ], [q], and [x], respectively in certain eastern dialects but that are merged into [g], [k], and [h] in western dialects and are therefore defectively represented in

5170-573: The Marmaray from Ayrılıkçeşmesi station (originally İbrahimağa station) on the Asian side under the Bosphorus and back again. On October 29, 2013, the first stage of the Marmaray project, the underground tunnel between Europe and Asia, was inaugurated on the 90th anniversary of the Turkish Republic'. The maiden journey took place after a grand opening ceremony attended by President Abdullah Gül and Prime Minister Erdoğan, as well as by

5280-417: The Marmaray will help to create a modern "Iron Silk Road " by allowing freight trains to travel between Europe and China . Freight trains that are not carrying dangerous goods will be able to use the tunnel when commuter services are not operating (between 1:00 a.m. and 5:00 a.m.). At other times only passenger trains will be in the tunnels. The Japan International Cooperation Agency (JICA) and

5390-544: The Port of Güllük (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

5500-444: The Port of Zonguldak , owned by Türkiye Taşkömürü Kurumu (Turkish Coal Company), the Port of Tekkeköy and the Port of Tekirdağ , owned by AKPORT AŞ. In 2004, the privatization of all ports except Haydarpaşa began. By 2014 Mersin, Iskenderun, Bandirma, Samsun ports had been privatized. Tender for privatization of Derince Port has also completed and waiting for takeover. The state railways are planning on building rail connections to

5610-535: The SOV structure has diminished relevance and may vary. The SOV structure may thus be considered a "pragmatic word order" of language, one that does not rely on word order for grammatical purposes. Consider the following simple sentence which demonstrates that the focus in Turkish is on the element that immediately precedes the verb: Ahmet Ahmet yumurta-yı Marmaray 15 minutes (Halkalı – Gebze) Marmaray ( pronounced [ˈmaɾmaɾaj] )

The plan included 5,538 km (3,441 mi) of new railway lines of which only 96 km (60 mi) were actually completed; the Gaziantep-Karkamış section of the Narlı-Nusaybin railway was completed in 1960. Turkish State Railways operated most trains in the country until

5830-469: The TDK were newly derived from Turkic roots, it also opted for reviving Old Turkish words which had not been used for centuries. In 1935, the TDK published a bilingual Ottoman-Turkish /Pure Turkish dictionary that documents the results of the language reform. Owing to this sudden change in the language, older and younger people in Turkey started to differ in their vocabularies. While the generations born before

5940-724: The Turkish State Railways operated 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 language makes usage of honorifics and has a strong T–V distinction which distinguishes varying levels of politeness, social distance , age, courtesy or familiarity toward the addressee. The plural second-person pronoun and verb forms are used referring to

6160-539: The Turkish language are, in their alphabetical order, ⟨a⟩ , ⟨e⟩ , ⟨ı⟩ , ⟨i⟩ , ⟨o⟩ , ⟨ö⟩ , ⟨u⟩ , ⟨ü⟩ . The Turkish vowel system can be considered as being three-dimensional, where vowels are characterised by how and where they are articulated focusing on three key features: front and back , rounded and unrounded and vowel height . Vowels are classified [±back], [±round] and [±high]. The only diphthongs in

6270-405: The United States, France, the Netherlands, Austria, Belgium, Switzerland, and the United Kingdom. Due to the cultural assimilation of Turkish immigrants in host countries, not all ethnic members of the diaspora speak the language with native fluency. In 2005, 93% of the population of Turkey were native speakers of Turkish, about 67 million at the time, with Kurdish languages making up most of

6380-437: The adoption of the new Turkish alphabet in 1928, shaped the modern Turkish language spoken today. The TDK became an independent body in 1951, with the lifting of the requirement that it should be presided over by the Minister of Education. This status continued until August 1983, when it was again made into a governmental body in the constitution of 1982 , following the military coup d'état of 1980 . Modern standard Turkish

One of the tasks of the newly established association was to initiate a language reform to replace loanwords of Arabic and Persian origin with Turkish equivalents. By banning the usage of imported words in the press, the association succeeded in removing several hundred foreign words from the language. While most of the words introduced to the language by

6600-455: 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. 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 .

Archaeologists also uncovered traces of the city wall of Constantine the Great , and the remains of several ships, including what appears to be the only ancient or early medieval galley ever discovered, preventing the project from proceeding as planned. In addition, archaeologists uncovered

Many of these new words, particularly information technology terms, have received widespread acceptance. However, the TDK is occasionally criticized for coining words which sound contrived and artificial. Some earlier changes—such as bölem to replace fırka , "political party"—also failed to meet with popular approval ( fırka has been replaced by

7040-480: The cost to the Turkish government had exceeded $ 500 million per year in addition to a subsidy of over $ 100 million. 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. As of 2008,

The rising presence of this very similar language in Azerbaijan and the fact that many children use Turkish words instead of Azerbaijani words due to satellite TV has caused concern that the distinctive features of the language will be eroded. Many bookstores sell books in Turkish language along Azerbaijani language ones, with Agalar Mahmadov, a leading intellectual, voicing his concern that Turkish language has "already started to take over

7370-455: 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,

7480-403: The discovery and excavation of these monuments and associated stone slabs by Russian archaeologists in the wider area surrounding the Orkhon Valley between 1889 and 1893, it became established that the language on the inscriptions was the Old Turkic language written using the Old Turkic alphabet , which has also been referred to as "Turkic runes" or "runiform" due to a superficial similarity to

7590-661: The discovery of historical and archaeological sites along the route as new stations were built, the first phase of the project was finally opened by president Erdoğan on October 29, 2013. The second phase of the project was scheduled to open in 2015 but work once again stopped in 2014. It was restarted in February 2017 and the line finally opened in its entirety on March 12, 2019. The trains came with completely new rolling stock , with carriages that can be walked through from end to end. The line can carry 75,000 passengers per hour in each direction (PPHPD). Travel time from Halkali to Gebze normally takes 104 minutes. The Marmaray

7700-606: The end of 2016. 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. The Turkish State Railways operated passenger services on 90% of their system. These are intercity, regional, commuter and international services. In

7810-449: The entire İstanbul-Ankara main line, to try to save its diminishing reputation. Construction started in 1987. Forty-five E43000 electric locomotives were ordered from Toshiba and built in Eskişehir by Tülomsaş , to be used on the line. Electrification was completed between Arifye and Eskişehir and electric trains began to run in 1989. Electrification was connected to Ankara in 1993. The major ore route between Divriği and İskenderun

7920-488: 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,

8030-452: The incompatible Russian broad gauge ). The two existing sections of the line were rebuilt and expanded from two tracks to three tracks , to allow for higher capacity with intercity and freight rail. The name Marmaray is a portmanteau of the words Marmara and Ray , which is Turkish for rail . Construction started in 2004 and was originally intended to be completed by April 2009. After multiple delays caused – among other things – by

8140-473: The lack of ü vowel in the Trabzon dialect means -un would be used in both of these cases — elun and kitabun . With the exceptions stated below, Turkish words are oxytone (accented on the last syllable). Turkish has two groups of sentences: verbal and nominal sentences. In the case of a verbal sentence, the predicate is a finite verb, while the predicate in nominal sentence will have either no overt verb or

8250-466: The language are found in loanwords and may be categorised as falling diphthongs usually analyzed as a sequence of /j/ and a vowel. The principle of vowel harmony, which permeates Turkish word-formation and suffixation, is due to the natural human tendency towards economy of muscular effort. This principle is expressed in Turkish through three rules: The second and third rules minimize muscular effort during speech. More specifically, they are related to

8360-429: The language reform, the Turkish education system discontinued the teaching of literary form of Ottoman Turkish and the speaking and writing ability of society atrophied to the point that, in later years, Turkish society would perceive the speech to be so alien to listeners that it had to be "translated" three times into modern Turkish: first in 1963, again in 1986, and most recently in 1995. The past few decades have seen

8470-505: The line were rebuilt or completely refurbished. Signalling was also modernised to allow trains to travel as close as two minutes apart (although in reality far fewer trains than that actually run). The suburban-rail upgrade part of the project, known originally as CR1, was first awarded to the AMD Rail Consortium, comprising Marubeni of Japan, Dogus Insaat of Turkey and Alstom of France. However, they were unable to complete

8580-525: The linguistic concept of accent , which is also covered with these words. Several universities, as well as a dedicated work-group of the Turkish Language Association, carry out projects investigating Turkish dialects. As of 2002 work continued on the compilation and publication of their research as a comprehensive dialect- atlas of the Turkish language. Although the Ottoman alphabet, being slightly more phonetically ambiguous than

8690-402: The modern Turkish language. While visiting the region between Adıyaman and Adana , Evliya Çelebi recorded the "Turkman language" and compared it with his own Turkish: Reforms Kemalism After the foundation of the modern state of Turkey and the script reform , the Turkish Language Association (TDK) was established in 1932 under the patronage of Mustafa Kemal Atatürk , with

8800-410: The national and natural dialects of Azerbaijan". However, the presence of Turkish as foreign language is not as high as Russian. In Uzbekistan, the second most populated Turkic country, a new TV channel Foreign Languages TV was established in 2022. This channel has been broadcasting Turkish lessons along with English, French, German and Russian lessons. Turkish is the official language of Turkey and

8910-421: The network in 2020, but the aim is for over three-quarters by 2023. Along with these several Turkish cities operate rapid transit and tram system electrified with either overhead wire or third rail. By 2013, the electrified lines reached to 2416 km. There is also 888 km of electrified high speed train network, which makes 3304 km in total. Turkish State Railways started an electrification plan in 1953. The plan

9020-486: The oldest evidence of settlement in Istanbul, with artefacts, including amphorae , pottery fragments, shells, pieces of bone and horse skulls, and nine human skulls found in a bag, dating back to 6,000 BCE. Glass artefacts and fragments dating from the Hellenistic, Roman, Byzantine and Ottoman periods were also found during excavations at Sirkeci. On August 4, 2013, Prime Minister Recep Tayyip Erdoğan , test-drove

9130-662: The overland travel time to 3 + 1 ⁄ 2 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,

9240-489: The personal ending, so for example Necla, siz öğretmen misiniz ? ('Necla, are you [formal, plural] a teacher?'). Word order in simple Turkish sentences is generally subject–object–verb , as in Korean and Latin , but unlike English, for verbal sentences and subject-predicate for nominal sentences. However, as Turkish possesses a case-marking system, and most grammatical relations are shown using morphological markers, often

9350-435: The phenomenon of labial assimilation: if the lips are rounded (a process that requires muscular effort) for the first vowel they may stay rounded for subsequent vowels. If they are unrounded for the first vowel, the speaker does not make the additional muscular effort to round them subsequently. Grammatical affixes have "a chameleon-like quality", and obey one of the following patterns of vowel harmony: Practically,

9460-638: The preceding vowel. In native Turkic words, the sounds [c] , [ɟ] , and [l] are mainly in complementary distribution with [k] , [ɡ] , and [ɫ] ; the former set occurs adjacent to front vowels and the latter adjacent to back vowels. The distribution of these phonemes is often unpredictable, however, in foreign borrowings and proper nouns. In such words, [c] , [ɟ] , and [l] often occur with back vowels: some examples are given below. However, there are minimal pairs that distinguish between these sounds, such as kar [kɑɾ] "snow" vs kâr [cɑɾ] "profit". Turkish orthography reflects final-obstruent devoicing ,

9570-440: The principles of i-type vowel harmony in practice: Türkiye' dir ("it is Turkey"), kapı dır ("it is the door"), but gün dür ("it is the day"), palto dur ("it is the coat"). These are four word-classes that are exceptions to the rules of vowel harmony: The road sign in the photograph above illustrates several of these features: The rules of vowel harmony may vary by regional dialect. The dialect of Turkish spoken in

9680-531: The private railway companies invested in container wagons, and carrying 20% of all rail freight by their own wagons. TCDD has plans to strengthen freight traffic by adding 4000 km of conventional lines until 2023. That includes new international rail connections to Georgia, Iraq and Iran. TCDD is also constructing 18 logistic centers to enable transportation of more loads by rail. TCDD is planning to increase its transit traffic (11000 to in 2011) by constructing "iron silk road" to connect Europe to Asia. Marmaray

9790-505: The project involved the renewal of the old suburban railway that ran between Halkalı and Kazlıçeşme on the European side of Istanbul and between Ayrılıkçeşmesi and Gebze on the Asian side. The work was meant to be completed at the same time as the first phase (the tunnel and underground sections), but was delayed until March, 2019. A third line was added to enable the electric multiple unit (EMU) cars and other railway carriages to move separately. Thirty-six above-ground stations along

9900-402: The railway's 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. Today, the passenger ratio

10010-575: The railways own and operated over 240 km (150 mi) of industrial lines and 206 km (128 mi) of high-speed lines , with 574 km (357 mi) of lines under construction. As of 2010, the railways consist of 763 tunnels, 25,441 bridges, 17 wyes and 7 loops . 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.TCDD also owns 3 rail ferries . Railways powered by electricity in Turkey comprised less than half of

10120-528: The railways passenger traffic. 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 100 km/h (62 mph) to 120 km/h (75 mph). 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,

10230-460: The remainder. Azerbaijani language , official in Azerbaijan, is mutually intelligible with Turkish and speakers of both languages can understand them without noticeable difficulty, especially when discussion comes on ordinary, daily language. Turkey has very good relations with Azerbaijan, with a multitude of Turkish companies and authorities investing there, while the influence of Turkey in

10340-550: The state owned companies TÜLOMSAŞ , TÜDEMSAŞ and TÜVASAŞ are affiliates. The TCDD has a 50% share in the İzmir Banliyö Taşımacılığı Sistemi A.Ş. (İZBAN A.Ş.) which operates the metro in İzmir , and a 15% share in EUROTEM . Currently rolling stock is the responsibility of TCDD Transport . TCDD directly owns and operated 8,697 km (5,404 mi) of common carrier lines, of which 1,920 km (1,190 mi) are electrified, throughout 57 provinces . Along with this,

10450-489: The success of electrifying suburban lines, the State Railways turned to electrify important main lines. The main reason for this is that tough gradients would be easier to climb with electric traction than steam or diesel traction. On February 6, 1977, TCDD finished the electrification as well as major earthworks of the Gebze-Adapazarı part of the İstanbul–Adapazarı main line . The State Railway then turned to electrify

10560-651: 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

10670-541: 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

10780-830: 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

10890-427: The tunnel is constructed has been known to liquefy during an earthquake so engineers injected industrial grout to 24 metres (79 ft) below the seabed to keep it stable. The walls of the tunnel are made of waterproof concrete coated with a steel shell, each section independently watertight. The tunnel is made to flex and bend in the way that tall buildings are constructed to react if an earthquake hits. Floodgates at

11000-432: The twofold pattern (also referred to as the e-type vowel harmony) means that in the environment where the vowel in the word stem is formed in the front of the mouth, the suffix will take the e-form, while if it is formed in the back it will take the a-form. The fourfold pattern (also called the i-type) accounts for rounding as well as for front/back. The following examples, based on the copula -dir ("[it] is"), illustrate

11110-621: The west, the influence of Ottoman Turkish —the variety of the Turkish language that was used as the administrative and literary language of the Ottoman Empire —spread as the Ottoman Empire expanded. In 1928, as one of Atatürk's reforms in the early years of the Republic of Turkey, the Perso-Arabic script -based Ottoman Turkish alphabet was replaced with the Latin script -based Turkish alphabet . Some distinctive characteristics of

11220-491: The wires were taken down and the line was re-electrified completely between 2006 and 2010. This line opened on August 30, 2010, between Alsancak-Cumaovası and October 29, 2010, between Alsancak and Aliağa. The United Kingdom through Export Finance, a credit agency gave a Turkish multinational a €781m loan to finish the High speed rail. The railway is between Gaziantep and Mersin through Adana and Osmaniye . Rönesans Holding,

11330-405: The work and it was re-tendered as contract CR3 in early 2011. The replacement contract worth €932.8 million was awarded to a joint venture between OHL and Invensys Rail. In February 2010, Railway Gazette International reported that the tunnel's administrators were hiring consultants to analyse options for carrying freight traffic. The Prime Minister and other officials have suggested that

11440-489: Was based mostly on the fact these languages share three features: agglutination , vowel harmony and lack of grammatical gender. The earliest known Old Turkic inscriptions are the three monumental Orkhon inscriptions found in modern Mongolia . Erected in honour of the prince Kul Tigin and his brother Emperor Bilge Khagan , these date back to the Second Turkic Khaganate (dated 682–744 CE). After

11550-449: Was chosen ahead of Alstom , CAF , and a consortium of Bombardier , Siemens , and Nurol . There are two depot and maintenance yards on the line (one at each end) where the sets are stocked. The project was delayed by four years, largely due to the discovery of Byzantine -era and other 8,000-year-old archaeological finds on the proposed site of the European tunnel terminal at Yenikapı in 2005. Excavations then produced evidence of

11660-503: Was complete and electric train started to run on December 4, 1955. The electrification got many positive reactions. In 1969, TCDD electrified the Haydarpaşa–Gebze part of the commuter railway in İstanbul. Several more sets of E8000 emus were ordered as well as 15 E40000 electric locomotives to meet the demands of the railway. The Ankara Suburban Railway was electrified in 1972 and brand new E14000 multiple units were ordered. With

11770-407: Was electrified in 1994 to make it easier for heavy trains to go up steep gradients. İstanbul to Edirne and Kapıkule was electrified in 1997 and 15 new E52500 electric locomotives were delivered from ASEA in 1998. In an attempt to revive İzmir's suburban network, Alsancak-Cumaovası and Basmane-Aliağa lines were electrified in 2001 and 2002 respectively. However these were not used at all. In 2006

11880-531: 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. 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%). By 2000,

11990-497: Was planned to be completely electrified in 2020. 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

12100-576: Was to first electrify important suburban lines in Istanbul and Ankara . The main reason for this was the many complaints of citizens living in the city about the pollution of the steam locomotives. The railways chose the standard 25 kV 50 Hz AC system to electrify with. The first line to be electrified was the Sirkeci -Halkalı line on the İstanbul commuter railway . Three electric locomotives were ordered from Alsthom and Jeumont from France as well as several sets of multiple units . Electrification
