History Of Rail Transport In Iran
In the second half of the 19th century, during the time of Nasser-al-Din Shah, a short horse-driven suburban railway was established south of Tehran that was later converted to steam. This line was closed in 1952. The Tabriz– Jolfa– Julfa (Russia) line (146 km) was opened in 1915 (in 1916 official opening), the Sufian–Sharafkhaneh (53 km) in 1916, and the Mirjaveh–Zahedan (93 km) in 1920. In 1915–1918, the Russians built and operated a military narrow-gauge railway Shakhtakhty (Russia) - Maku (Persia)- Bayazed (Turkey). World War II 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 1939. The railroad was built with rail weighing 67 pounds per yard (33 kg/m) and required more than 3000 bridges. There were 126 tunnels in the Zagros mountains. The longest was 1.5 miles. Grades averaged 1.5 percent south of Tehran, but then increased to 2 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nasser-al-Din Shah
Naser al-Din Shah Qajar ( fa, ناصرالدینشاه قاجار; 16 July 1831 – 1 May 1896) was the fourth Shah of Qajar Iran from 5 September 1848 to 1 May 1896 when he was assassinated. He was the son of Mohammad Shah Qajar and Malek Jahan Khanom and the third longest reigning monarch in Iranian history after Shapur II of the Sassanid dynasty and Tahmasp I of the Safavid dynasty. Nasser al-Din Shah had sovereign power for close to 51 years. He was the first modern Persian monarch who formally visited Europe and wrote of his travels in his memoirs. A modernist, he allowed the establishment of newspapers in the country and made use of modern forms of technology such as telegraphs, photography and also planned concessions for railways and irrigation works. Despite his modernizing reforms on education, his tax reforms were abused by people in power, and the government was viewed as corrupt and unable to protect commoners from abuse by the upper class which led to increasi ...

Silk Road
The Silk Road () was a network of Eurasian trade routes active from the second century BCE until the mid-15th century. Spanning over 6,400 kilometers (4,000 miles), it played a central role in facilitating economic, cultural, political, and religious interactions between the Eastern world, East and Western world, West. The name "Silk Road", first coined in the late 19th century, has fallen into disuse among some modern historians in favor of Silk Routes, on the grounds that it more accurately describes the intricate web of land and sea routes connecting East Asia, East and Southeast Asia, the South Asia, Indian subcontinent, Central Asia, the Middle East, East Africa and Southern Europe, Europe. The Silk Road derives its name from the highly lucrative trade of silk, silk textiles that were Silk industry in China, produced almost exclusively in China. The network began with the Han dynasty, Han dynasty's expansion into Central Asia around 114 BCE, Protectorate of the Western Regio ...

Sarakhs
Sarakhs ( fa, سرخس, Saraxs, also Romanized as Serakhs) is a city in Sarakhs County, Razavi Khorasan Province, Iran. Sarakhs was once a stopping point along the Silk Road, and in its 11th century heyday had many libraries. Much of the original city site is now just across the border at Serakhs in Turkmenistan. According to the most recent national census, in 2006, the city's population was 33,571 in 8,066 families. History Several Battle of Sarakhs (other), battles were fought in this area. According to Ferdowsi's Shahnameh the town has existed since the Afrasiab period and was named for its builder, Sarakhs, son of Godarz, by Keykavus. The surrounding oasis has been inhabited since 2nd millennium BCE and Turkmen historians consider the city to have been founded in 507 BCE. Although this is considered to be a somewhat arbitrary choice of date, the section of the city called Sarahs that's now on the Turkmenistan side of the border, duly celebrated its 2500th annive ...

Mashad
Mashhad ( fa, مشهد, Mašhad ), also spelled Mashad, is the second-most-populous city in Iran, located in the relatively remote north-east of the country about from Tehran. It serves as the capital of Razavi Khorasan Province and has a population of 3,001,184 (2016 census), which includes the areas of Mashhad Taman and Torqabeh. The city has been governed by different ethnic groups over the course of its history. Mashhad was once a major oasis along the ancient Silk Road connecting with Merv to the east. It enjoyed relative prosperity in the Mongol period. The city is named after the shrine of Imam Reza, the eighth Shia Imam, who was buried in a village in Khorasan which afterward gained the name, meaning the "place of martyrdom". Every year, millions of pilgrims visit the Imam Reza shrine. The Abbasid caliph Harun al-Rashid is also buried within the same shrine. Mashhad is also known colloquially as the city of Ferdowsi, after the Iranian poet who composed the ''Shahna ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bandar Abbas
Bandar Abbas or Bandar-e ‘Abbās ( fa, , , ), is a port city and capital of Hormozgān Province on the southern coast of Iran, on the Persian Gulf. The city occupies a strategic position on the narrow Strait of Hormuz (just across from Musandam Governorate, Oman), and it is the location of the main base of the Iranian Navy. Bandar Abbas is also the capital and largest city of Bandar Abbas County. At the 2016 census, its population was 526,648. Etymology Bandar Abbas has always been a port, and as such its various names have all reflected this function. The most common name over time, Gameroon, traditionally derived from Turkish ''gümrük'', "customhouse" (from Late Greek ''kommerkion'', from Latin ''commercium'', "commerce"), but is now speculated to come from Persian ''kamrūn'', "shrimp" (in Portuguese: ''camarão'', similar to the former Portuguese name). Its current name derives from that of Abbas the Great () paired with ''bandar'' - "port", meaning "Port of Abbas" ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ruling Grade
The term ruling grade is usually used as a synonym for "steepest climb" between two points on a railroad. More simply, the steepest grade to be climbed dictates how powerful the motive power (or how light the train) must be in order for the run to be made without assistance. Even if 99% of the line could be run with a low-powered (and inexpensive) locomotive, if at some point on the line there is a steeper gradient than such train would be able to climb, this gradient "rules" that a more powerful locomotive must be used, in spite of it being far too powerful for the rest of the line. This is why special "helper engines" (also dubbed "Bankers") are often stationed near steep grades on otherwise mild tracks. It is cheaper than running a too-powerful locomotive over the entire track mileage just in order to make the grade, especially when multiple trains run over the line each day (to help justify the fixed daily cost of the helper operation). In the 1953 edition of ''Railway Engineer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spiral (railway)
A spiral (sometimes called a spiral loop or just loop) is a technique employed by railways to ascend steep hills. A railway spiral rises on a steady curve until it has completed a loop, passing over itself as it gains height, allowing the railway to gain vertical elevation in a relatively short horizontal distance. It is an alternative to a zig-zag, and avoids the need for the trains to stop and reverse direction while ascending. If the train is longer than the length of each loop it may be possible to view it looping above itself. The term "loop" is also often used for a railway that curves sharply and goes back on itself: if the railway crosses itself, then it forms a spiral or helix; otherwise, it forms the much more common horseshoe curve or bend.

ALCO RS-1
The ALCO RS-1 was a 4-axle diesel-electric locomotive built by Alco-GE between 1941 and 1953 and the American Locomotive Company from 1953 to 1960. ALCO subsidiary Montreal Locomotive Works built an additional three RS-1s in 1954. This model has the distinction of having the longest production run of any diesel locomotive for the North American market. The RS-1 was in production for 19 years from the first unit Rock Island #748 in March 1941 to the last unit National of Mexico #5663 in March 1960. Design In 1940, the Rock Island Railroad approached ALCO about building a locomotive for both road and switching service. To meet the Rock Island's request, ALCO created the RS-1. Their new design was a hood unit, in contrast to most existing locomotive designs at the time which were predominantly carbody units. The hood unit design allowed for improved visibility, especially to the rear. Rear visibility is very important for switching, which often involves reverse movements. Unlike ...

Shatt Al-Arab
The Shatt al-Arab ( ar, شط العرب, lit=River of the Arabs; fa, اروندرود, Arvand Rud, lit=Swift River) is a river of some in length that is formed at the confluence of the Euphrates and Tigris rivers in the town of al-Qurnah in the Basra Governorate of southern Iraq. The southern end of the river constitutes the Iran–Iraq border down to its mouth, where it discharges into the Persian Gulf. The Shatt al-Arab varies in width from about at Basra to at its mouth. It is thought that the waterway formed relatively recently in geological time, with the Tigris and Euphrates originally emptying into the Persian Gulf via a channel further to the west. Kuwait's Bubiyan Island is part of the Shatt al-Arab delta. The Karun, a tributary which joins the waterway from the Iranian side, deposits large amounts of silt into the river; this necessitates continuous dredging to keep it navigable. The area used to hold the largest date palm forest in the world. In the mid-1970s, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Railway Trend In Iran
Rail transport (also known as train transport) is a means of transport that transfers passengers and goods on wheeled vehicles running on rails, which are incorporated in Track (rail transport), tracks. In contrast to road transport, where the vehicles run on a prepared flat surface, rail vehicles (rolling stock) are directionally guided by the tracks on which they run. Tracks usually consist of steel rails, installed on Railroad tie, sleepers (ties) set in track ballast, ballast, on which the rolling stock, usually fitted with metal wheels, moves. Other variations are also possible, such as "slab track", in which the rails are fastened to a concrete foundation resting on a prepared subsurface. Rolling stock in a rail transport system generally encounters lower friction, frictional resistance than rubber-tyred road vehicles, so passenger and freight cars (carriages and wagons) can be coupled into longer trains. The rail transport operations, operation is carried out by a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
