The Unsan Line is a former non-electrified narrow gauge line of the Korean State Railway in North P'yŏngan Province, North Korea, running from Puksinhyŏl-li, Hyangsan County on the Manp'o Line to Samsal-ri, Unsan County.

History

The Unsan Line was originally opened by the Korean State Railway in the 1970s; it was closed some time in the 1990s.

Trains on the line were pulled by Czechoslovak-built 400 series 0-6-0T steam tank locomotives.

By December 2003, there was little that remained of the line, with only the bridge abutments leaving Puksinhyon station being visible and no buildings or locomotives seen.
