The Kim Chong-t'ae Electric Locomotive Works (Korean: 김종태전기기관차연합기업소) in P'yŏngyang is North Korea's largest manufacturer of railway equipment.^[1] Established in November 1945 in Sŏsŏng-guyŏk,^[2] P'yŏngyang near the P'yŏngyang Railway University and the Korean State Railway's West P'yŏngyang Station, the factory manufactures and overhauls electric and diesel locomotives, passenger cars, streetcars and subway trainsets.^[3] It is subordinate to the North Korean Ministry of Railways.^[4]

History

Initially established as a repair facility for rolling stock during the Japanese occupation of Korea,^[4] becoming the state-owned West P'yŏngyang Railway Factory on 10 November 1945. In 1960, the facility repaired 210 steam locomotives, 1,800 freight cars and 120 passenger cars.^[5] It was expanded with Polish assistance in the late 1950s to manufacture electric locomotives as well, with work on the manufacturing facility completed on 29 August 1959.^[1] In 1961 it was renamed P'yŏngyang Electric Locomotive Works, and the first electric locomotive manufactured in North Korea was built at this factory in 1961, and the plant was awarded a medal following a visit by Kim Il Sung.^[3] Kim Il Sung paid another visit to the factory on 27 September 1987, to inspect the first completed production unit of the Red Flag 6-class articulated 8-axle electric locomotive.^[1]

Following the execution of South Korean revolutionary activist Kim Chong-t'ae, a member of the Revolutionary Party for Reunification, the factory was renamed in his honour in 1969.^[3]

In May 2023 it was announced that the Kim Jong-thae Electric Locomotive Complex is planned to move from its current location at Sosong District to a new complex to be located in an empty field in Sunan District at the northern part of the city, geo-located at (39°03′38″N 125°41′53″E / 39.060606°N 125.698131°E / 39.060606; 125.698131).^[6]

Manufacturing activities

As the only plant in North Korea capable of manufacturing electric and diesel locomotives. the history of the Kim Chong-t'ae Electric Locomotive Works is intricately tied into the history of diesel and electric motive power in North Korea.^[4]

From 1961 the plant had the capacity to build 30 new electric locomotives per year in addition to the repair and construction of passenger cars.^[5] At present, the facility covers 400,000 m² (4,300,000 sq ft), of which construction facilities cover 130,000 m² (1,400,000 sq ft) divided into 15 workshops. The company employs 5000 people. It is capable of handling 100-110 electric locomotives per year, of which 30-50 can be of new construction; the biggest single-year output was 60 new units.^[4]

North Korea produced its first electric locomotives in 1961, the Red Flag 1. Since then, the Kim Chong-t'ae Works has manufactured a number of other types, such as the Red Flag 6-class electric articulated locomotive and several other electric types, the Kŭmsong and Saebyŏl-class diesel locomotives along with other diesel shunters, the Juche-class 4-section electric multiple-unit train and various diesel and electric locomotives for narrow gauge lines. In recent years, the factory has also manufactured streetcars to a Czech ČKD Tatra design.

Since the 1990s, an important undertaking has been the conversion of diesel locomotives to electric operation. The biggest such project thus far has been the conversion of the Soviet-made M62-type diesel locomotives to electric operation, resulting in the Kanghaenggun-class locomotives.^[1]

Following a visit of North Korean leader Kim Jong Il on 5 January 2002, the plant began work on a new range of electric locomotives,^[7] which ultimately led to their latest product, the 2,700 kW (3,600 hp) Sŏngun Red Flag-class electric freight locomotive with asynchronous motors with a maximum speed of 120 kilometres per hour (75 mph).^[8] The first prototype was unveiled on 5 January 2011, and production versions have since begun entering service.^[9]

The plant has also produced a trainset for the P'yŏngyang Metro, unveiled at a ceremony at the plant on 23 October 2015, with Kim Jong Un in attendance.^[10] The trainset was delivered in late 2015 and went into service in January 2016.^[11]

Current production consists of the Sŏngun Red Flag 4-axle locomotives, the 3,160 kW (4,240 hp) Red Flag 5400-class Bo-Bo-Bo electric locomotive, the 4,200 kW (5,600 hp) Red Flag 7-class electric articulated locomotive, along with a small number of 249 kW (334 hp) diesel-hydraulic and 176 kW (236 hp) kW diesel-mechanical locomotives, narrow-gauge electric and 551 kW (739 hp) narrow-gauge diesel locomotives.
