Rail Transport In Iran

Iran has a state-owned railway system built to standard gauge (1,435 mm (4 ft 8½ in)) which falls under the remit of the Ministry of Roads & Urban Development. The primary rail carrier is the Islamic Republic of Iran Railways (abbreviated as IRIR, or sometimes as RAI, or as IRI Railway) which is the national state-owned railway system of Iran

In 2008, the IR operated 11,106 km of rail with a further 18,900 km in various stages of development. Almost all of this is standard gauge of , but 94 km are Russian gauge of to link up to ex-Soviet Union border states. There is also the no-longer-isolated Indian gauge section of from Zahedan to the Pakistan border that continues to Quetta and the Indian sub-continent. The extent of double-track lines is 1,082 km. The Jolfa–Tabriz line is electrified (148 km). In 2006, IR reported that it possessed 565 engines, 1,192 passenger coaches, and 16,330 wagons. The vast majority of the engines are diesel-powered.

History

Qajar dynasty

In 1886, during the time of Nasser-al-Din Shah, an 8.7 km horse-driven suburban railway was established south of Tehran, which was later converted to steam. This line was closed in 1952. The First Iranian railway was set up in 1887 between Mahmudabad and Amol; its construction was completely private. However it was not used because of several problems. The Tabriz– Jolfa line (146 km) was built in 1914, the Sufiyan–Sharafkhaneh line (53 km) in 1916, and the Mirjaveh–Zahedan line (93 km) in 1920.

Interwar period

The long Trans-Iranian Railway from Bandar Shah on the Caspian Sea to Bandar Shahpur on the Persian Gulf was opened during the reign of Reza Shah Pahlavi in 1938. The railroad was built with rail weighing and required more than 3000 bridges. There were 126 tunnels in the Zagros mountains, the longest of which was . Grades averaged 1.5 percent south of Tehran, but then increased to 2.8 percent to cross the pass between Tehran and the Caspian Sea.

Anglo-Soviet Invasion of Iran

After the Anglo-Soviet invasion of Iran in 1941, this Persian Corridor became one of the supply routes for war material for the Soviet Union during World War II ( Railway trend in Iran). The invading British built a branch line from the bridge over the Karun River in Ahvaz to a new southern port at Khorramshahr on the Arvand Rud river. In 1943, 3,473 American soldiers of the Military Railway Service began running trains between the Persian Gulf and Caspian Sea using ALCO RS-1 locomotives rebuilt with 3-axle trucks and designated RSD-1. The Americans set up headquarters in Ahvaz, but were unable to tolerate the daytime heat, and generally operated the railway at night. The Persian Gulf Command ran trains day and night.

Challenging construction

The ''Trans-Iranian'' railway traverses many mountain ranges, and is full of spirals and 1 in 36 (2.78%) ruling grades. Much of the terrain was unmapped when construction took place, and its geology unknown. Several stretches of line, including tunnels, were built through unsuitable geology, and had to be replaced before the line opened. For example
* one tunnel went through a salt dome so that ground water was bound to dissolve the foundations; this tunnel and its approaches had to be completely replaced.

The railways have undergone extensions including the 1977 linking to the western railway system at the Turkish border, the 1993 opening of the Bandar Abbas line providing better access to the sea, and the 1996 opening of the Mashad–Sarakhs extension as part of the ''Silk Road railway'' to link to the landlocked Central Asian Countries.

Railway construction

In December 2014, a rail line from Iran opened to Turkmenistan and Kazakhstan. The opening of the line marks the first direct rail link between Iran, Kazakhstan and China, and upon completion of the Marmaray rail project direct rail transport between China and Europe (while avoiding Russia) will be possible.

Rolling stock

Iran Railways uses a variety of rolling stock for their services. Trains are operated with diesel and electric locomotives. Steam locomotives have been phased out. Diesel is a strategic industry, and by using this heavy oil as a fuel instead of gas for locomotives, the Islamic Republic of Iran has joined the 12 world countries which manufacture this type of engine.

Operations

The Islamic Republic of Iran Railways is the national state-owned railway system of Iran. The Raja Passenger Train Company is an associate of the IR, and manages its passenger trains. The Railway Transportation Company is an associate of the IR, which manages its freight transport. The Ministry of Roads & Urban Development is the state agency that oversees the IRIR. Some 33 million tonnes of goods and 29 million passengers are transported annually by the rail transportation network, accounting for 9 percent and 11 percent of all transportation in Iran, respectively (2011).
In 2008, the IR operated 11,106 km of rail with a further 18,900 km in various stages of development. Almost all of this is standard gauge of , but 94 km are Russian gauge of to link up to ex-Soviet Union border states. There is also the no-longer-isolated Indian gauge section of from Zahedan to the Pakistan border that continues to Quetta and the Indian sub-continent. The extent of double-track lines is 1,082 km. The Jolfa–Tabriz line is electrified (148 km). In 2006, IR reported that it possessed 565 engines, 1,192 passenger coaches, and 16,330 wagons. The vast majority of the engines are diesel-powered.

Expansion

The majority of transportation in Iran is road-based. The government plans to transport 3.5% of the passenger volume and 8.5% of the freight volume by rail. Extensive electrification is planned. The railway network expands by about 500 km per year according to the Ministry of R&T. According to plan, Iran's railway lines are to reach 15,000 kilometers by 2015 and 25,000 kilometers by the year 2025. The State Railways Company has 300 locomotives with an average lifespan of 40 years. The Islamic Republic of Iran Railways, the Iran Power Plant Projects Management (Mapna) and Germany's Siemens have signed a contract for 150 IranRunner locomotives for passenger trains. Siemens is committed to exporting to Iran some 30 locomotives in the first phase, and to manufacturing another 120 using domestic capacities and expertise over the next 6 years (2007). MLC (Mapna Locomotive Engineering and Manufacturing Company) is the manufacturing company responsible for this production. Another locomotive manufacturer in Iran is Wagon Pars which builds AD43C locomotives in partnership with Iranian power plant maker DESA diesel. In 2009, €17 billion in foreign investment in the rail industry has been secured, according to the Ministry of Road and Transportation of Iran.

Network and corridors

The railway network converges on Tehran. The Iranian cities of Isfahan and Shiraz were linked to Tehran in 2009. Further extension of this line to Bushehr and Bandar Abbas is planned. Furthermore, the construction of Chabahar-Zahedan-Mashhad railway, extending from southeast to northeast of the country to the length of 1,350 kilometers, started in 2010 with 3 billion euro credit. The western railway extension links to Turkey at the Rāzī– Kapıköy border. There is a northern connection to Azerbaijan, the Caucasus, and Russia has a bogie-changing station at the border at Jolfa. The southern routes connect Tehran to the Persian Gulf ports of Bandar Imam and Bandar Abbas. A line to the Caspian Sea ends at the terminal of Amir Abad and at Bandar Torkaman, and is part of a north–south corridor to Russia and Scandinavia. The north-east corridor connects Mashhad and continues further to the bogie-changing station at Sarakhs. For the landlocked countries of Turkmenistan, Uzbekistan, Tajikistan, Kyrgyzstan, and Kazakhstan this line provides access to the sea. A recent connection from Mashhad to Bafq has significantly shortened access to the port city of Bandar Abbas. Tehran-Mashhad with a length of 900 kilometers, Tehran-Qom-Esfahan with a length of 410 kilometers (under construction), Qazvin-Rasht-Anzali-Astara with a length of 370 kilometers; will all be built with help from China at a cost of $12 billion. In total, Iran has signed a number of contracts with China for the development of 5,000 kilometres of railway lines.

North-South Railway

The north–south railway is complete between Bandar-e Anzali and Bandar Abbas; the line was initially expected to be completed as far as Azerbaijan by the end of 2016. Qazvin to Astara was the missing link in the North-South Transportation Corridor, which links India, Iran, Azerbaijan, Russia and Finland. Qazvin-Rasht railway was completed in 2018 and Rasht-Anzali in 2023 whilst Anzali-Astara railway needs another four years to be completed.

Links to

Azerbaijan and Armenia

Iran's first rail link to the outside world appeared simultaneously with the beginning of the country's railway system, as Iran's first major railway (1916) connected Tabriz with Jolfa on the border with the Russian Empire. The link continued its importance throughout the USSR era; Iran and the USSR signed an agreement on cross-border rail transport in 1940, and amended it in 1958. It is reported that during the late-Soviet era, some 350 railcars crossed the border at Jolfa daily, with the annual amount of cross-border freight reaching 3.5 million tons. However, after the breakup of the USSR and the closing of the border between Armenia and Azerbaijan the Jolfa connection became a dead end, as it only links Iran with the isolated Nakhichevan exclave of the Republic of Azerbaijan. In 2007, Iranian Railways, Azerbaijan State Railway and Russian Railways agreed on implementing the project to build a new line between Qazvin, Resht, Astara, Iran and Astara, Azerbaijan. In April 2017, Russia and India celebrated 70 years of diplomatic relations and vowed to complete the North-South Transportation Corridor (NSTC) with the help of Iran. The NSTC reduces time and cost of travel by 30-40%.There is presently no direct railway connection between Iran and Armenia, even though the two countries share a border. In 2009, Iran and Armenia agreed to build a railway linking Armenia with Iran's Persian Gulf ports.

Links to

Central Asia

In 1996, Mashhad–Sarakhs extension connected Iran to Turkmenistan, as part of the ''Silk Road railway'' to link to the landlocked Central Asian Countries. Former states of the Soviet Union have railways using a Russian gauge, thus the Iranian Railways maintain break-of-gauge services at borders to Azerbaijan and Turkmenistan, and beyond brief wide-track rail segments to the border crossing. The Kazakhstan-Turkmenistan-Iran railway link is a part of the North-South Transport Corridor and is a long railway line connecting the Central Asian countries of Kazakhstan and Turkmenistan with Iran and the Persian Gulf. It will link Uzen in Kazakhstan with Bereket - Etrek in Turkmenistan and end at Gorgan in Iran's Golestan province. In Iran, the railway will be linked to national network making its way to the ports of the Persian Gulf. The project is estimated to cost $620m which is being jointly funded by the governments of Kazakhstan, Turkmenistan and Iran.

Links to

Iraq, Syria and Afghanistan

Feasibility studies were started on Khorramshahr-Basra and Kermanshah-Baghdad links with Iraq. , the Iranian line to Khorramshahr was finished, but construction had not started on the track from the Iraqi border to Basra. In 2017, the West Corridor known locally as Rahahane Gharb was expanded from Arak to Malayer and Kermanshah. The Iranian government plans on expanding the network further to Khosravi (Iran-Iraq) border. China Civil Engineering Construction Corp is building the Malayer-Khosravi corridor, which will eventually run to the border with Iraq. On 27 December 2021, Iran and Iraq agreed to build a railway connecting both countries.The project would connect Basra in southern Iraq to Shalamcheh in western Iran. There are only around 30 kilometers (18 miles) between the two areas. The railway would be strategically important for Iran, linking the country to the Mediterranean Sea via Iraq and Syria's railways.

Mashhad- Khvaf-Afghanistan's Border-Islam Qala railway is being constructed by an Iranian firm, with funding from the Afghan government, but the section in Afghanistan remains incomplete. On 10 December 2020, the first rail link between Iran and Afghanistan on Khaf - Herat route between Khaf and Rahzanak in Afghanistan for a distance of was formally inaugurated although traffic had started on 12 December 2002 with a 500 tonnes test train cement delivery from Iran. The works on remaining section of the project between Rahzanak and Herat is in progress. The works on both sides are done as development assistance to Afghanistan by Iran. The new Khaf - Rahzanak rail line continues from Khaf to Torbat-e Heydarieh where it links with Mashhad - Bafq railway line a crucial rail link opened in 2009 which connects port city, Bandar Abbas in Persian Gulf with north eastern city of Mashhad and from there with Turkmenistan through Sarakhs.

Link to Turkey, and International Standard Gauge route to Europe

In 1977, the Iranian railways linked to the western railway system at the Turkish border. The route to the west into Turkey terminates at Van with a train ferry for both freight wagons and international passenger traffic (baggage car only) across Lake Van, which is at an altitude of , to Tatvan
