The Pukbunaeryuk Line, also called the Hyesan–Manp'o Ch'ŏngnyŏn Line after the only completed stage of three planned stages, is an electrified standard-gauge secondary trunk line of the Korean State Railway in Chagang and Ryanggang Provinces, North Korea, connecting the Manp'o Line at Manp'o to the Paektusan Ch'ŏngnyŏn Line at Hyesan.^[1] It also connects to the China Railway Meiji Railway via the Ji'an Yalu River Border Railway Bridge between Manp'o and Meihekou, China.

The Pukbunaeryuk Line was to have been a northern east–west trunk line of 450 km (280 mi)^[2] on the Manp'o–Hyesan–Musan–Hoeryŏng route,^[3] but this plan has not been realised.

There are 42 stations on the line, of which Chasŏng, Hwap'yŏng, P'op'yŏng Ch'ŏngnyŏn, and Mint'ang are dedicated freight consolidation points; the stations of Chŏnp'yŏng, Tuji, Sinp'a Ch'ŏngnyŏn, Ryanggang Sinsang, and Insan are served only by passenger trains.^[3] The line has 76 tunnels totalling over 26 km (16 mi) in length, and 116 bridges with a total length of over 6.3 km (3.9 mi) -^[4] bridges make up 3.3% of the total length of the line, whilst tunnels account for 12.8% of the total route length.^[3]

There are locomotive facilities at Manp'o and Hyesan, and formerly at P'op'yŏng; Hyesan also has shops for maintenance of passenger and freight cars.^[3]
