The Kim Chong-t'ae Electric Locomotive Works (Korean: 김종태전기기관차연합기업소) in P'yŏngyang is North Korea's largest manufacturer of railway equipment.

[4] 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.

[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.

[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.

[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).
