The Sŏhae Kammun Line, or West Sea Barrage Line is a non-electrified standard-gauge secondary line of the Korean State Railway located entirely within Namp'o Special City, North Korea, and running from Ch'ŏlgwang on the Ŭnnyul Line to Sillyŏngri on the P'yŏngnam Line.^[1]

The Sŏhae Kammun Line runs over the West Sea Barrage; of the 26.7 km (16.6 mi) total length of the line, over 6 km (3.7 mi) runs over the dam itself. There is a swing bridge of approximately 100 m (328 ft 1 in), built by the Namp'o Shipyard, over the locks.

The line was opened on 24 June 1986, after the completion of the West Sea Barrage.^[1][2]

A local passenger train, 361/362, operating between Namp'o and Ch'ŏlgwang, runs on the entirety of this line between Sillyŏngri and Ch'ŏlgwang, stopping only at Namp'o, Sŏhae Kammun, and Ch'ŏlgwang; scheduled travel time in the 2002 timetable was 2 hours 20 minutes each way.^[3]

A yellow background in the "Distance" box indicates that section of the line is not electrified.
