Soho Line


The Sŏho Line is an electrified narrow gauge railway line of the Korean State Railway in Hamhŭng-si, North Korea, running from Hamhŭng to Hŭngnam and Sŏho.

History

During the Japanese colonial era, the privately owned Sinhŭng Railway built a network of narrow-gauge railways around Hamhŭng. These were the Hamnam Line, the Jangjin Line, and the Songheung Line opened between 1923 and 1933, and the Namhŭng Line, which was opened in three sections between 1934 and 1936.

The Sinhŭng Railway was bought by the Chosen Railway on 22 April 1938.
After the defeat of Japan in the Pacific War and the subsequent partition of Korea, the entirety of the line, being north of the 38th parallel, was located in the Soviet zone of occupation; on 10 August 1946, the Provisional People's Committee for North Korea nationalised all railways within its jurisdiction, including the Namhŭng Line, and it has since been operated by the Korean State Railway.
Originally built entirely as a narrow gauge line, frequent accidents on the line led the Korean State Railway to convert the Hamhŭng—Sinhŭng section of the Sinhŭng Line to standard gauge for greater safety and increased transportation capacity; after the regauging of this section was completed, West Hamhŭng station was disconnected from the Sinhŭng line. When Naeho Station was closed, the line between Hadŏk and Sŏho was realigned to the current, shorter alignment.
