The DK4 (abbreviation for Diandong Keche 4 ; "Electric multiple unit 4 ") is a multiple unit series that was mostly used on the Pyongyang metro and later on the Beijing metro . This series is a variant of the DK2 series, which was in use on the Beijing subway from 1969. Between 1972 and 1978 a total of 345 double units were produced and delivered. In the meantime almost all vehicles have been taken out of service, only a four-car set has been preserved for rush hour traffic; this is now used as a museum train occasionally on national holidays.
Whereabouts
The cars were used in Pyongyang for a period of more than 25 years before they were replaced by the Berlin transport company from 1997 onwards by used D ("Dora") and GI ("Gisela") vehicles .
After a large proportion of the vehicles were sold to the Beijing subway in 1998 , they were in use on Line 13 until 2002. The remaining in North Korea railcars were largely for operation on railway lines of the Korean National Railway converted. A four-car train remained in the metro's inventory as a reserve for times of rush hour traffic .
Remarks
Although North Korea claims that the vehicles were produced by the Kim Chŏng-tae electric locomotive works , they are from the Chinese company Changchun Railway Vehicles . The internal name is DKJI (JI = Kim Jong-il ).
