Juche-class EMU

The Juche-class (Korean: 주체) is a 4-part electric multiple unit built by the Kim Chong-t'ae Electric Locomotive Works in 1976, intended for high speed train service for the Korean State Railway.[1]

Description

Electric railcars had been used in Korea before the war by the Kŭmgangsan Electric Railway,[2] and these were used by Korean State Railway until the line was destroyed during the Korean War,[3] and no further electric railcars were used after that for many years. However, the opening of the P'yŏngyang Metro in 1973, along with worldwide attention on high-speed electric trainsets such as the Japanese Shinkansen put into service in 1964[4] and the ER200 class introduced by the Soviet Railways in 1974,[5] led the Railway Ministry to direct efforts towards the development of a high-speed train for North Korea, resulting the unveiling of North Korea's first electric trainset, the Juche-class EMU, in 1976.[1] Externally, the four-car set was similar in appearance to the 181 series trainsets used by the Japanese National Railways on the Kodama limited express of the day; internally, despite all of North Korea's electrification being 3000 V DC, the Juche-class EMU was built for two-system operation - possibly with a view to future operation in South Korea, where AC electrification was used.[6]

Operation

Trials were carried out around P'yŏngyang, but no further sets were built,[6] suggesting that the experiment was deemed a failure. The set remained in storage until 1998, when it was refurbished, repainted, and put into use on a daily commuter service for scientists between P'yŏngyang and Paesanjŏm, taking one hour to cover the 38 km (24 mi) distance each way.[1]

gollark: Probably other bad things, but I've mostly been looking at it from a potatOS viewpoint.

gollark: Succeeded in what?
gollark: No, the fact that it's a mostly uncontrolled and highly intelligent AI.
