Husan_Line
The Husan Line is a non-electrified standard-gauge freight-only secondary line of the Korean State Railway located entirely within Namp'o Special City, South P'yŏngan Province, North Korea, running from Husan on the Ryonggang Line to Yangmak.[1]
The Husan Line runs 3.7 km (2.3 mi) along the west side of the Ryongho Reservoir to serve a number of industries around Yangmak. The industrial trackage continues for a ways beyond Yangmak to the Yangmak granite quarry.
