Gyeongwon Line
After the partition of Korea following the end of the Pacific War in 1945, the Gyeongwon Line was split along the 38th parallel between the stations of Hantangang and Choseongni. The railways in both South and North were nationalised, and the newly-established Korean National Railroad took over operation of the truncated Gyeongwon Line, from Seoul to Choseongni; in the North, the Korean State Railway merged its section of the Gyeongwon Line, Choseong-ri−Wonsan, with the Wonsan−Gowon section of the former Hamgyeong Line to create the Gangwon Line.
