History On 8 July 1938, the Chōsen Pyeongan Railway opened the Oncheon Line from Jinnampo, terminus of the Chosen Government Railway's Pyeongnam Line, to Yonggang Oncheon, running passenger trains to serve the hot springs there.朝鮮總督府官報 (The Gazette of the Governor-General of Korea), Showa No. 3447, 14 July 1938
After the partition of Korea the line was within the territory of the DPRK, and was nationalised by the Provisional People’s Committee for North Korea along with all other railways in the Soviet zone of occupation on 10 August 1946,Kokubu, Hayato, 将軍様の鉄道 (Shōgun-sama no Tetsudō), p. xiv, to be operated by the Korean State Railway, which merged the Oncheon Line into the Pyeongnam Line.
Services Two trains stopping at every station were listed in the 1945 timetable, one from Botonggang Station in suburban Pyongyang, and the other from Deokcheon on the West Chosen Central Railway's Seoseon Line. The reason for needing a train connecting these two cities is unclear. However, the train left Deokcheon at 3:12 PM, arriving at Oncheon at 2:45 AM the next morning; then, it departed Oncheon at 4:05 AM, arriving at Botonggang at 8:55 AM before returning to Oncheon and thence to Deokcheon.
