The Kangwŏn Line is a 145.8 km (90.6 mi) electrified standard-gauge trunk line of the Korean State Railway of North Korea, connecting Kowŏn on the P'yŏngra Line to P'yŏnggang, providing an east–west connection between the P'yŏngra and Ch'ŏngnyŏn Ich'ŏn lines.^[1]

Although the line continues south across the Korean Demilitarized Zone, it is non-operational south of P'yŏnggang.

The ruling gradient is 25‰, the minimum curve radius is 300 m (980 ft); there are 94 bridges with a total length of 3,493 m (11,460 ft), and 18 tunnels with a total length of 6,243 m (20,482 ft). There are 23 stations on the line, with an average distance between stations of 6.5 km (4.0 mi). Wŏnsan Station is the most important station on the line; in addition to its passenger infrastructure, locomotive and freight car maintenance facilities are located there.^[2]

On 5 August 2015, South Korean President Park Geun-hye attended a ceremony launching work on the reconstruction of the 9.3 km (5.8 mi) Baengmagoji–Woljeong-ri section of Korail's Gyeongwon Line, which has been closed since the Korean War, as part of events marking the 70th anniversary of the partition of Korea. The works are to begin in October and are expected to be finished by 2017; the US $129 million project is being funded by the Unification Ministry. Park also stated her hope that the remaining 2.4 km (1.5 mi) section across the DMZ would be rebuilt soon, which would re-establish the old Kyŏngwŏn Line connecting Seoul to Wŏnsan.^[3]
