The Ch'ŏngnyŏn Ich'ŏn Line is an electrified standard-gauge secondary mainline of the Korean State Railway running from P'yŏngsan on the P'yŏngbu Line to Sep'o on the Kangwŏn Line.^[1] The 141.3 km (87.8 mi) line is the southernmost of the three east-west transversal mainlines in North Korea.^[2]

The Ch'ŏngnyŏn Ich'ŏn line plays an important role in the movement of freight between the east and west coasts of the DPRK, relieving the burden on the P'yŏngra Line. As of 1985, the Sep'o Ch'ŏngnyŏn−Chihari section is under the jurisdiction of the Hamhŭng Railway Bureau, whilst the Chŏngbong−P'yŏngsan section is administered by the Sariwŏn Railway Bureau.^[2]

There are 18 stations, of which 3 are halts. Ich'ŏn Ch'ŏngnyŏn and Chŏngbong stations are designated freight concentration points, where goods to and from counties in the area without rail service are transferred between road and rail. Ich'ŏn Ch'ŏngnyŏn Station handles passenger and freight for Ich'ŏn, Ch'ŏrwŏn, P'an'gyo, and Pŏptong counties, while Chŏngbong Station handles them for Kosan, Sinp'yŏng, Singye and Suan counties.^[2]
