The Korean State Railway is the operating arm of the Ministry of Railways of the Democratic People's Republic of Korea and has its headquarters at P'yŏngyang. The current Minister of Railways is Chon Kil-su, who has held the position since 2009.[2][3]

History

The railway lines of North Korea were originally built during the Japanese occupation of Korea by the Chosen Government Railway (Sentetsu), the South Manchuria Railway (Mantetsu) and various privately owned railway companies such as the Chosen Railway (Chōtetsu). The Pacific War had left Korea's railways massively damaged. However, reconstruction work began immediately after the partition of Korea, and by 1948, when the People's Democratic Republic of Korea - and the Korean State Railway - was established, 3,767 km (2,341 mi) of railway was in functional condition,[4] including the restoration of the electrification on the Yangdŏk-Ch'ŏnsŏng section of the P'yŏngra Line, and the new electrification of the Kaegu-Koin section of the Manp'o Line.[5]

Other new construction took place prior to 1950, but the Korean War undid these gains, leaving North Korea's railway network devastated. Through the Korean War, much of the infrastructure and most locomotives were destroyed. With the aid of the Chinese People's Volunteer Corps, by the time of the ceasefire in July 1953 1,382 km (859 mi) of railway lines had been restored. Within three months after the armistice, 308 bridges with a total length of 15,000 m (49,000 ft) were either repaired or newly built by railway corps volunteers, 37 stations were rebuilt as the railway network was restored to its pre-war status. With extensive Soviet and Chinese assistance, the railways were rebuilt and further expanded.[4]

Large-scale electrification after the destruction of the Korean War began in 1958, and by 1973 over 1,300 km of lines had been electrified, realising the goal of electrifying all major trunk lines. By the end of the 1970s, the goal of eliminating steam power from the primary trunk lines had been achieved.[4]

In addition to the construction of new lines and electrification, the Railway Ministry also established various other railway-related undertakings, such as the Kim Chong-t'ae Electric Locomotive Works, the P'yŏngyang Railway University, and rolling stock factories in Chongjin and Wonsan, etc.[4]

Since 1994, the economic difficulties have led to the deterioration of rolling stock and infrastructure, significantly reducing operational capacity and efficiency.[4]

In July 2000, talks began between the two Koreas to discuss the reopening of the former Kyŏngŭi Line that once ran between Seoul and Sinŭiju via P'yŏngyang;[10] this line is now split between the P'yŏngŭi Line in the north running from Sinŭiju to P'yŏngyang and the P'yŏngbu Line from P'yŏngyang via Kaesŏng to the Korean Demilitarized Zone, and Korail's Gyeongui Line, which runs from the DMZ via Dorasan to Seoul. Groundbreaking ceremonies took place in September 2002 for the reconstruction of this line and the reconnection of the former Tonghae Pukpu Line on the east coast,[10] which is presently split between the North's Kŭmgangsan Ch'ŏngnyŏn Line from Anbyŏn on the Kangwŏn Line via Kŭmgangsan to the DMZ, and the southern section of the former Tonghae Pupkpu line from the DMZ to Jejin.[10]

2004 saw the worst known railway disaster in North Korea when an explosion at the station in Ryongch'ŏn destroyed buildings in a large swathe around the city's station, killing 54 and injuring 1,245 people in the blast itself and the subsequent fires, according to official casualty reports.[11] A wide area was reported to have been affected, with some airborne debris reportedly falling across the border in China; the Red Cross reported that 1,850 houses and buildings had been destroyed and another 6,350 had been damaged.[12]

The inter-Korean rail lines were finally reopened on 17 May 2007, nearly seven years after negotiations on the subject began between North and South.[10] An agreement on cross-border operations had been made between the Korean State Railway and Korail already in April 2004, but three subsequent attempts to run trains failed, until finally the military authorities on both sides adopted a security agreement on 11 May 2007, allowing the reopening of the lines on 17 May. The reopening consisted of two ceremonial trains, one over the western line from Munsan to Kaesŏng (27 km (17 mi)), and another over the eastern line from Kŭmgangsan to Jejin. The western train was operated from south to north by a Korail locomotive and five coaches, while the eastern train was pulled by a Korean State Railway locomotive and five coaches; each train carried 150 invited guests from the South and the North.[10]

Commercial freight operations were finally restarted on 11 December 2007, with the first train carrying construction materials from Munsan in the South to the Kaesŏng Industrial Region, and footwear and clothing on the return trip to the South. This service, operated by Korail, has been interrupted several times as a result of political events between North and South that have caused the closure of the industrial district. The industrial district was most recently reopened on 16 September 2013 after a five-month shutdown.[13] At the same time, passenger services were reopened on the eastern line to carry passengers to the Mount Kŭmgang Tourist Region, although that service was discontinued in July 2008 after the shooting of a South Korean tourist.[14]

In 2008, work began on the reconstruction of the line between Tumangang Station on the DPRK-Russian border and the port of Rajin, where construction of a new container terminal to handle freight traffic from Asia Pacific countries to Europe.[15] This, which would cut down considerably on transit time when compared to shipping by sea. This project fits within the framework of a cooperation agreement made between Russia and North Korea in 2000, and is viewed as the first step in the reconstruction of a Trans-Korean mainline, which would allow the shipment of goods by rail all the way from South Korea to Europe.[16] The project included restoring 18 bridges, 12 culverts and three tunnels with a combined length of more than 4.5 km,[17] as well as laying 54 km of four-rail dual gauge (1,435 mm and 1,520 mm) track.[16] A transfer terminal at the port is nearing completion, along with dredging and construction of a quay, storage areas, industrial and office buildings. A single control centre will manage future operations on the line, which will be capable of handling up to 4 million tonnes of cargo per year from the port.[17] Operation and management of the upgraded line, which cost over 5.5 billion rubles (excluding the cost of the port upgrades), will be handled by a joint venture of the Russian Railways and the Port of Rason, which has formally leased the line for 49 years. The upgrade work was officially completed on 22 September 2013.[17]

Pak Yong-sok was the Railways Minister until his replacement by Kim Yong-sam in September, 1998. In 2008, an inspection of the railways was carried out by the National Defence Commission, revealing massive corruption, as a result of which Kim Yong-sam was removed from the position and handed over to the State Security Department.[18] He was then replaced by the current Railways Minister, Chon Kil-su, in October 2008.[19] The investigation revealed that railway workers had stripped nearly 100 locomotives held in strategic reserve for wartime use, selling the parts as scrap metal; as the minister responsible, Kim was held accountable and was removed from his post,[18] and was reportedly executed in March 2009.[19]

On 8 December 2013, an agreement was reached between North Korea and a consortium of Chinese companies to construct a high-speed railrway connecting Kaesŏng, P'yŏngyang, and Sinŭiju. The project is to be a build-operate-transfer arrangement, in which the construction, scheduled to take five years, will be funded by the consortium, which will then operate the line for 30 years, after which the Railway Ministry will take over operations and complete ownership of the line. The rail line is to be a double-track line of about 400 km (250 mi) with an operating speed of over 200 km/h (120 mph).[20]

On 21 October 2014 a groundbreaking ceremony for the Sŭngri ("Victory") project to modernise the P'yŏngnam Line from Namp'o to P'yŏngyang and the P'yŏngdŏk Line from P'yŏngyang to Chedong was held. The project, supported by Russia, is intended to form the first stage of a larger-scale cooperation with the Russian Railways as part of a 20-year development project that would modernise around 3,500 km of the North Korean rail network, and would include the construction of a north–south freight bypass around P'yŏngyang. The overall project cost is estimated to be around US $25 billion, and it is expected that exports of coal, rare earth and non-ferrous metals from the DPRK to Russia will provide the funding for the project.[21]

Organisation

The Korean State Railway is the operating arm of the North Korean Ministry of Railways. It is divided into five Regional Bureaus: P'yŏngyang, Kaech'ŏn, Hamhŭng, Ch'ŏngjin, and Sariwŏn.[22]

Also subordinate to the Railway Ministry are five major industrial concerns: the Kim Chong-t'ae Electric Locomotive Works in P'yŏngyang, the 4 June Rolling Stock Works in Wŏnsan, the Ch'ŏngjin Railway Factory, the 7.6 Vehicle Parts Factory and the Pyongyang Rolling Stock Repair Works. Of these, the Kim Chong-t'ae Works and the 4 June Works are by far the most important.[4]

There are four research institutes subordinate to the Railway Ministry for scientific research, design review, and the exploration of new technologies for the design and production of rolling stock (the P'yŏngyang Railway University, also subordinate to the Ministry, also takes part in design work and design review), and product inspection; inspection of the products of the factories is also undertaken by the national quality inspection board.[4]

Operations and Infrastructure

The Korean State Railway operates over 5,248 km of railway, of which 4,725 km (2,936 mi) is 1,435 mm (4 ft 8 1⁄2 in) standard gauge, 523 km (325 mi) of 1,524 mm (5 ft) broad gauge, and 523 km (325 mi) is 762 mm (2 ft 6 in) narrow gauge Of the total, about 80% is in regular use.[23] 3,893.5 km (2,419.3 mi) of the standard gauge lines are electrified at 3 kV DC and 295.5 km (183.6 mi) of the narrow gauge at 1.5 kV DC. Manual and semi-automatic substations are used, located 15, 30 or 60 km apart (50–60 km apart on the Kangwŏn Line).[23]

North Korea's national transportation policy focusses on the railway as the primary means of transport for both passengers and freight. Passenger services include both long-distance trains, as well as commuter services for students and workers; freight transport focusses on industrial raw materials and military traffic, as well as import-export traffic. Traffic control is by track warrant.[23]

In recent years, emphasis has been placed on moving away from railway to road transport for movements of 150–200 km or less, due to the greater cost effectiveness of road transport over short distances.[23]

Railways carry a very large portion of traffic in North Korea:[25]

Due to the ageing infrastructure, normal operation is made difficult by chronic power shortages and poor state of infrastructure maintenance.[23] Sleepers, tunnels and bridges are in a critically poor state of repair.[25] Tracks are laid on either wooden or concrete sleepers, using rails of 37, 40, 50, 60 kg/m (75, 81, 101, 121 lb/yd) of domestic, Chinese and Russian manufacture. Riverine gravel and crushed stone ballast is used. Tunnels are of concrete construction; many are in poor condition, having been built during the colonial era.[23] Communications equipment and the semi-automatic signalisation infrastructure dates to the 1970s, and was imported from China and the Soviet Union.[25] The poor state of the infrastructure severely restricts operational speeds - average train speeds are as low as 20–60 km/h (in South Korea 60–100 km/h): only on the P'yŏngbu Line are speeds of 100 km/h possible.[25]

Passenger Service

The railway provides the primary form of long-distance transport in North Korea.[23]

The most important international service is the P'yŏngyang - Sinŭiju - Beijing train which operates four times weekly (Monday, Wednesday, Thursday and Saturday). Customs and immigration checks take place at Sinŭiju. The trip takes 22 hours 51 minutes from P'yŏngyang to Beijing, and 23 hours 18 minutes from Beijing to P'yŏngyang. Stops made in the DPRK are at P'yŏngyang, Ch'ŏngju Ch'ŏngnyŏn, Ch'ŏnggang and Sinŭiju Ch'ŏngnyŏn stations.[27]

The train is generally composed of eight coaches and one dining car operating between P'yŏngyang and Sinŭiju, two North Korean sleeping cars between P'yŏngyang and Beijing, and three China Railways coaches and one Korean State Railway sleeping car between P'yŏngyang and Dandong, China.

The only other international service is a sleeping car that operates fortnightly between P'yŏngyang and Moscow.

Other important long-distances trains include amongst others P'yŏngyang - Kilju - Hyesan (721 km (448 mi), P'yŏngyang - Ch'ŏngjin - Tumangang (1,011 km (628 mi)), P'yŏngyang - Ch'ŏngjin - Musan (813 km (505 mi)), P'yŏngyang - Kŭmgol (570 km (350 mi)), P'yŏngyang - Kowŏn - P'yŏnggang (370 km (230 mi)), Haeju - Manp'o (492 km (306 mi)), Haeju - Sariwŏn - P'yŏngyang - Kilju - Hyesan (855 km (531 mi)), Sinch'ŏn - Sariwŏn - P'yŏngyang - Ch'ŏngjin (858 km (533 mi)) and Sinŭiju - Kaesŏng (413 km (257 mi)).[28]

Routes

North Korea has an extensive network of standard and narrow gauge rail lines,[28] roughly forming an H-shape, with an east–west mainline connecting the two north–south mainlines on the eastern and western coasts.[23]

This list shows only the main trunk lines; branchlines are described on each line's page. For secondary standard-gauge lines and narrow-gauge lines, see the main article.

Trunk Lines


Narrow-gauge Lines
Narrow-gauge lines in North Korea are built to 762 mm gauge. Some are electrified at 1500 V DC. While there are such lines all over the country, the most important ones are in the northern part of the country. The longest of the narrow-gauge lines in North Korea is the Paengmu Line, which runs 191.7 km from Paegam to Musan, connecting the standard-gauge Paektusan Ch'ŏngnyŏn Line with the standard-gauge Musan Line.

Rolling Stock

The Korean State Railway operates a wide variety of electric, diesel and steam locomotives, along with a variety of electric multiple unit passenger trains. The KSR's motive power has been obtained from various sources. Much, mostly steam and Japanese-made electric locomotives, was left over after the end of the colonial era, and this motive power moved the majority of trains between the time of the partition of Korea and the beginning of the Korean War.[28]

The Korean War destroyed much of the North's railway infrastructure, but with extensive Soviet and Chinese aid, along with aid from the rest of the Eastern Bloc - mostly in the form of steam locomotives from Hungary, Czechoslovakia, Poland and Romania, North Korea's railways were rapidly rebuilt. During the Ch'ŏllima Movement, North Korea's equivalent to China's Great Leap Forward,[29] Kim Il-sung placed a special emphasis on the electrification of the railways. As a result of this emphasis, many hundreds of kilometres of railway were electrified by the end of the 1950s.[30]

Another important aspect of the Ch'ŏllima Movement was the further industrialisation of North Korea. In terms of industry, the Japanese legacy was a fairly extensive network of railways connecting steel mills, chemical plants and other heavy industries with the many mines of the north - coal, iron, and many other metal and non-metal resources; all of these were further expanded during the 1950s. In 1945, a rolling stock repair facility in P'yŏngyang,[31] eventually becoming today's Kim Chong-t'ae Electric Locomotive Works, which has manufactured almost all of North Korea's electric locomotives since the first Red Flag 1-class locomotive, North Korea's first domestically produced electric locomotive, was rolled out in 1961.[4]

With ample coal supplies to fire steam locomotives, and electrification of the rail network being expanded rapidly after the Korean War, dieselisation was not the priority for the Korean State Railway that it was for many other railways, not starting in earnest until the second half of the 1960s with the arrival of the first diesel locomotives from Hungary and the Soviet Union. Once there, though, they have consistently shared the burden with electric and steam locomotives, taking over the latter's share of work on non-electrified lines gradually.[28] Though still in sporadic use, steam had mostly left the North Korean mainlines by the end of the 1970s,[4] and elsewhere by the end of the 1990s.

Severe floods in the 1990s had taken their toll on North Korea's hydroelectric generation system, and even some mines had flooded - and due to electricity shortages caused by the silting of the dams, there was often little electricity available to run pumps needed to clear the water out of the mines. By the turn of the millennium, the Korean State Railway was having difficulties keeping electric trains running, and the fleet of K62s was insufficient to meet the transportation needs, even though they'd dropped significantly due to ongoing economic difficulties. To alleviate this problem, more M62s from several European countries, along with a sizeable number of second-hand locomotives from China, were imported.[28] At the same time, however, the economic crisis also made it difficult to obtain diesel fuel, and by the late 1990s rail traffic was barely plodding along.

In recent years, extensive work has begun on refurbishing the rail network and power generation capabilities in the country, but diesels continue to play their significant role in hauling passenger and freight trains on the various mainlines, and Kim Jong-un has been placing special emphasis on the refurbishment and modernisation of the railways.[32] Due to ongoing economic difficulties in North Korea, maintenance levels are poor; locomotive serviceability is estimated at 50%.[25] However, recent imports of diesel locomotives from China and construction of newer electric locomotive types are helping to ameliorate the situation.[4]


At the present time the Korean State Railway operates primarily using electric and diesel power, with a wide array of locomotive types. Most numerous and important are the Red Flag 1-class electrics, the Red Flag 6-class articulated electrics for heavy freight trains, and the Kanghaenggun-class electrics, which were converted from diesels; also important are the K62-class diesels, and the various types imported recently from China. Efforts to modernise the motive power stock are also underway, with the continuing construction of Red Flag 5400-class heavy electrics and the latest addition, the Sŏngun Red Flag-class electrics designed to provide greater performance with lower power consumption,[33] along with a program to modernise the K62 diesels with new engines and other upgrades.[34]
