what is it?
The DK4 are a class of electrical multiple units built by Changchun Railway Vehicles, operated on the Pyongyang Metro, and later the Korean State Railway. The sets developed in parallel with the DK3, and these sets were delivered new to the Pyongyang Metro when it opened in September 1973, although they have since almost entirely disappeared from the metro network, with many sets being converted to be used under overhead catenary as electric multiple units, or as a locomotive.
