Kim Jong Thae DK4

In the 1990s, Kim Jong Thae started producing reverse engineered DK4 carriages, both with a driver's cabin and without. The first such set was rolled out as the Yonggwang-ho; later, non-driving motor cars were also produced and inserted into existing original Changchun DK4 consists. Unlike Changchun built carriages, these had longitudinal (side) seating and were of noticeably poorer quality.

90年代初，金钟泰电力机车厂开始仿制长春DK4列车。1992年，“荣光”号列车出厂，编组为Mc-M-M-Mc。后期生产车辆为M车，用于对长春DK4的扩编。
