Baghdad Railway The Baghdad Railway ( , , ) , was built from 1903 to 1940 to connect Berlin with the ( then ) Ottoman Empire city of Baghdad , where the Germans wanted to establish a port in the Persian Gulf , with a line through modern - day Turkey , Syria , and Iraq . Completion of the project took several decades and by the outbreak of World War I , the railway was still 960 km ( 600 miles ) away from its intended objective . The last stretch to Baghdad was built in the late 1930s and the first train to travel from Istanbul to Badhdad departed in 1940 . Funding and engineering was mainly provided by German Empire banks and companies , which in the 1890s had built the Anatolian Railway ( " Anatolische Eisenbahn " ) connecting Constantinople , Ankara and Konya . The Ottoman Empire wished to maintain its control of Arabia and to expand its influence across the Red Sea into the nominally Ottoman ( until 1914 ) Khedivate of Egypt , which had been under British military control since the Urabi Revolt in 1882 . The Germans gained access to and ownership of oil fields in Iraq , and with a line to the port of Basra would have gained better access to the eastern parts of the German colonial empire , by avoiding the Suez Canal . The railway became a source of international disputes during the years immediately preceding World War I . Although it has been argued that they were resolved in 1914 before the war began , it has also been argued that the railway was a leading cause of the First World War . Technical difficulties in the remote Taurus Mountains and diplomatic delays meant that by 1915 the railway was still short of completion , severely limiting its use during the war in which Baghdad was occupied by the British while the Hejaz railway in the south was attacked by guerrilla forces led by T . E . Lawrence . Construction resumed in the 1930s and was completed in 1940 . A history of this railway in the context of World War I history has lately emerged to describe the German interests in countering the British Empire , and Turkey ' s interest in countering their Russian rivals . As stated by a contemporary ' on the ground ' at the time , Morris Jastrow wrote " It was felt in England that if , as Napoleon is said to have remarked , Antwerp in the hands of a great continental power was a pistol leveled at the English coast , Baghdad and the Persian Gulf in the hands of Germany ( or any other strong power ) would be a 42 - centimetre gun pointed at India . " Overview . If it had been completed earlier , the " Berlin - Baghdad " ( and ultimately " Basra " ) railway would have enabled transport and trade from Germany through a port on the Persian Gulf , from which trade goods and supplies could be exchanged directly with the farthest of the German colonies , and the world . The journey home to Germany would have given German industry direct supply of oil . This access to resources , with trade less affected by British control of shipping would have been beneficial to German economic interests in industry and trade , and threatening to British economic dominance in colonial trade . The railway also threatened Russia , since it was accepted as axiomatic that political influence followed economic , and the railway was expected to extend Germany ' s economic influence towards the Caucasian frontier and into north Persia where Russia had a dominant share of the market . By the late 19th century the Ottoman Empire was weak , and cheap imports from industrialised Europe and the effects of a disastrous war had resulted in the country ' s finances being controlled by the Ottoman Public Debt Administration , composed of and answerable to the Great Powers . The Europeans saw great potential to exploit the resources of the weakening empire , irrigation could transform agriculture , there were chrome , antimony lead and zinc mines and some coal . Not least there was potentially vast amounts of oil . As early as 1871 a commission of experts studied the geology of the Tigris and Euphrates rivers and reported plentiful oil of good quality , but commented that poor transportation made it doubtful these fields could compete with Russian and American ones . During 1901 a German report announced the region had a veritable " lake of petroleum " of almost inexhaustible supply . In 1872 German railway engineer Wilhelm von Pressel was retained by the Ottoman government to develop plans for railways in Turkey . However , private enterprise would not build the railway without subsidies , so the Ottoman Government had to reserve part of its revenues to subsidise its construction , thus increasing its debt to the European powers . The process of construction of a rail line from Constantinople to Baghdad begun during 1888 when Alfred von Kaulla , manager of Württembergische Vereinsbank , and Georg von Siemens , Managing director of Deutsche Bank , created a syndicate and obtained a concession from Turkish leaders to extend the Haydarpaşa - İzmit Railway to Ankara . Thus came into existence the Anatolian Railway Company ( SCFOA , or ARC ) . After the line to Ankara was completed during December 1892 , railway workshops were built in Eskişehir and permission was obtained to construct a railway line from Eskişehir to Konya , and that line was completed in July 1896 . The two lines were the first two sections of the " Baghdad Railway " . Another railway built at the same time by German engineers was the Hejaz railway , commissioned by Sultan Hamid II . The Ottoman Empire chose to place the line outside the range of the British Navy guns . Therefore , the coastal way from Alexandretta to Aleppo was avoided . The line had to cross the Amanus mountains inland at the cost of expensive engineering including an 8 km tunnel between Ayran and Fevzipaşa . The Baghdad Concession . During 1898 and 1899 the Ottoman Ministry of Public Works received many applications for permission to construct a railway to Baghdad , it was not because of lack of competition that the Deutsche Bank was finally awarded the concession . A Russian plan was rejected for fear of it extending Russian influence in Constantinople . A well - financed British plan collapsed due to the outbreak of the Boer War . A well - financed French proposal titled the Imperial Ottoman Railway enabled them to become financiers of the winning Deutsche Bank plan . Other nations of Europe paid little attention to the building of the railway lines until 1903 when the Ottoman Government gave permission to an Ottoman corporation to build the railway line from Konia to Baghdad . This " Baghdad Railway Company " was controlled by a few German banks . McMurray rejects the theory that the railway tied Turkey to Germany . There was concern in Russia , France , and Britain after 1903 as the implications of the German scheme to construct a great " Berlin - Baghdad " railway became apparent . A railway that would link Berlin to the Persian Gulf would provide Germany with a connection to its southernmost colonies in Africa , i . e . with German East Africa ( present - day Rwanda and Burundi and the mainland part of Tanzania ) and German South - West Africa ( present - day Namibia , less Walvis Bay ) . The railway might eventually have strengthened the Ottoman Empire and its ties to Germany and might have shifted the balance of power in the region . Despite obstructions at the diplomatic level , work slowly began on the railway . Both geographical and political obstacles prevented the completion of the " Baghdad Railway " before World War I commenced in 1914 . Much of the construction work was undertaken by Philipp Holzmann . Route . The railway passed through the following towns and places , north to south : The Mersin – Yenice – Adana line existed prior to the construction of the Bagdad railway and was used for the latter in its Yenice – Adana section . British view of the railway . The initial reaction of Britain was one of strong support . A long article outlining the positive benefits of the enterprise appeared in the Times newspaper . It was argued that Germany was a major trading partner of Britain , and that though the competition for trade would affect Britain the fact that it was a good trading partner that was winning the trade instead would make up for the loss . The railway would obviously compete with British trade in Mesopotamia , but this would not happen for many years . However in 1906 the Hamburg - American Steamship Line announced its intention to run regular steamships between Europe and the Persian Gulf . After a futile price war the British lines , which had lost their monopoly , came to agreement in 1913 with their competitors , ending a rivalry which had caused considerable political concern . In 1911 the railway company looked to build a branch line to Alexandretta from Aleppo to pick up on the valuable trade of Northern Syria and the Northern Mesopotamian valley . However the Young Turk government could not offer further railway concessions without raising customs duties from 11 to 14 percent . Such a raise required the agreement of all the powers , but was vetoed by Britain after Sir Edward Grey spoke in the House of Commons — " . . . if the money is to be used to promote railways which may be a source of doubtful advantage to British trade . . . I say it will be impossible for us to agree to that increase . . . " . The British realised that the railways would be slightly too close to their oilfields in Persia . The British were worried that the Young Turks could block off oil supplies vital for the navy . The main British commercial interest that the British government insisted was protected , was that of the Right Honorable James Lyle Mackay , Baron Inchcape of Strathnaver . As well as being the foremost shipping magnate of the British Empire , Lord Inchcape was a director of the Anglo - Persian Oil Company and of the D ' Arcy Exploration Company . On February 23 a contract was signed in London between Lord Inchcape and the Baghdad Railway Company . In March 1914 the German government was obliged to recognize southern Mesopotamia , as well as central and southern Persia , as the exclusive field of operations of the Anglo - Persian Company . Role in origins of World War I . Discussion of the railway ' s role as a contributing factor to the outbreak of war is complicated by two issues : Firstly , historians and political analysts who wrote about this issue directly after the war were not in possession of closed diplomatic records . Full diplomatic documents of the German government were released between 1922 and 1927 , British documents between 1926 and 1938 . Only some Russian documents were released , and Italian documents only came out after the Second World War . Secondly , war historians tend to give an interpretation of the facts that is clouded by their own partisanship , political orientation , language , and contemporary perspectives . Socialist historians emphasised imperial rivalries and economic monopolies as the driving force for the war , as was popularly reported with respect to the railway at the time and especially as revealed in the Russian diplomatic documents . Regardless of diplomacy , financing and agreements , and later points of view , the existence of the railway would have created a threat to British dominance over German trade , as it would have given German industry access to oil , and a port in the Persian Gulf . The importance of oil as opposed to coal as fuel was recognised , as it could greatly improve the performance and capacity of the rival navies . The presence of the British there , and the creating of Kuwait to block non - British access to the Persian Gulf speaks to the strategic importance . Other historians have argued that intractable nationality issues in the denial of self - determination to minority groups were among the dominant causes of World War I . They argue that although the railway issue was heated before 1914 ( Corrigan shows that the railway issue was driving Germany and Turkey further apart ) conservative historians agree that it was not a cause of World War I , because the main controversies ( over financing ) had been resolved before the war started . " Some of the optimism should be attributed to the willingness of the German government to compose long - standing differences . . . and in June 1914 a settlement was achieved over the Baghdad railway . " ( Evans ) " Many economic and colonial issues which had been causing friction between French , German and British governments before 1914 , such as the financing of the Berlin - Baghdad railway and the future disposition of the Portuguese colonies , had been resolved by the summer of 1914 . " ( Henig ) However , war began on August 1 , 1914 — and one day later the secret treaty establishing the Ottoman - German Alliance was signed , perhaps giving credence to the notion that the issue had not been fully resolved . In fact , restriction of German access to Mesopotamia and its oil , and strategic exclusion from rail access to the Persian Gulf was enforced by British military presence during World War I , and afterwards by removal of the would - be Baghdad Railway from German ownership . Thus the potential consequences to Anglo - German economic rivalry in oil and trade by the existence of the railway , rather than the financing of it is seen by some as the deeper issue . During the War . By 1915 , the railway ended some 50 miles east of Diyarbakır . Another spur , heading east from Aleppo , ended at Nusaybin . Additionally some rail was laid starting in Baghdad reaching north to Tikrit and south to Kut . This left a gap of some 300 miles between the railway lines . Additionally , there were three mountains which the railway was going to go through , but the tunnels through these three mountains were not complete . So the railway was , in fact , broken into four different sections at the start of the war . The total time to get from Constantinople to Baghdad during the war was 22 days . The total distance was 1 , 255 miles ( 2019 km ) . The breaks in the railway meant that the Ottoman government had significant difficulties in sending supplies and reinforcements to the Mesopotamian Front . The fighting in Mesopotamia remained somewhat isolated from the rest of the war . During the conflict , Turkish and German workers laboured to complete the railway for military purposes but with limited manpower and so many more important things to spend money on , only two of the gaps were closed . After the war . In 1919 , the Treaty of Versailles cancelled all German rights to the " Baghdad Railway " . However , the " Deutsche Bank " transferred its holdings to a Swiss bank . People in Turkey , Italy , France , and Britain created various arrangements that gave a certain degree of control over the " Baghdad Railway " to various indistinct interests in those nations . Investors , speculators , and financiers were involved by 1923 in secretive and clandestine ways . The British Army had completed the southeastern section from Baghdad to Basra , so that part was under British control . The French held negotiations to obtain some degree of control over the central portion of the railway , and Turkish interests controlled the oldest sections that had been constructed inside of Turkey , but talks continued to be held after 1923 . The United States involvement in the Near East began in 1923 when Turkey approved the Chester concession , which aroused disapprovals from France and the United Kingdom . In 1930 , a passenger service by road was introduced to bridge the missing section of line between Nusaybin and Kirkuk . At different times the service used Rolls - Royce cars and Thornycroft buses . In 1932 , the Kingdom of Iraq became independent from the UK . In 1936 , Iraq bought all railways in its territory from the UK and started building the missing section of line from Tel Kotchek to Baiji . On July 15 , 1940 , the railway had been completed and two days later the " Taurus Express " made its first complete journey between Istanbul and Baghdad . In that year , the Robert Stephenson and Hawthorns locomotive works in Britain built a class of streamlined Pacific steam locomotives to haul the " Taurus Express " between Baghdad and Tel Kotchek . These were delivered to Iraqi State Railways in 1941 and entered service as the PC class . A new standard gauge railway opened between Baghdad and Basra for freight traffic in 1964 and for freight in 1968 . This replaced a metre gauge line built in 1920 and for the first time connected the Bosporus with the Persian Gulf without a break of gauge . Due to the strained relations between Turkey , Syria and Iraq however , continuous traffic remained rare , and other means of transport soon reduced its strategic and economic relevance . Current situation . Most of the line is in a usable condition . Robinson ' s " World Rail Atlas " shows it as intact . Most of the stations are still original . The part between Toprakkale and Narlı in Turkey has been electrified for heavy ore transport . The right - of - way of the railway marks the border between Syria and Turkey for over 350 km , from Çobanbey station in the West to Nusaybin in the east , with the rail line on the Turkish side squeezed between the minefields and control strip in Turkey and Syria . On February 16 , 2010 , the link between Mosul in Iraq and Gaziantep in Turkey was reopened . The first train went from Mosul to Gaziantep , lasting 18 hours . On February 18 , a return journey departed from Gaziantep to Mosul . This line has now closed once again .
