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'olgwang, runs on the entirety of this line between Sillyŏngri and Ch'ŏlgwang.[1]


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