The P'yà Ângbuk Line is an electrified standard-gauge secondary trunk line of the Korean State Railway in North Pyà Ângan Province, North Korea, running from Chà Ângju on the P'yà Ângà Âi Line to Ch'à Ângsu; it meets the Ch'à Ângnyà Ân P'arwà Ân Line at Kusà Âng, and at Ch'à Ângsu, via a bridge across the Yalu River, it goes to Shanghekou, China, where it connects to China Railway's Fengshang Railway to Fenghuangcheng.
The line was opened by the privately owned P'yà Ângbuk Railway on 27 September 1939 as an industrial railway to serve the Sup'ung Hydroelectric Power Plant on the Yalu River. The Emperor of Manchukuo, Puyi, travelled along this line when he visited the Sup'ung Dam.
Following the partition of Korea the line was located within the Soviet zone of occupation, and was nationalised along with all the other railways in the zone by the Provisional PeopleâÂÂs Committee for North Korea on 10 August 1946, becoming part of the Korean State Railway. Electrification of the entire line was completed in 1980, and at the same time, semi-automatic train control was installed on the section between Chà Ângju and Kusà Âng.
The line serves a variety of industries, including a textile factory in Kusà Âng, a chemical factory in Ch'à Ângsu, and North Korea's largest lignite mine near P'ungnyà Ân, as well as shipping large amounts of wood south from Amrokkang Station on the Yalu River. Other important commodities shipped on the line are limestone and anthracite.
There are two long-distance passenger trains that operate on the line - semi-express trains 115/116 between P'yà Ângyang and Ch'à Ângsu, and local trains 200/201 between West P'yà Ângyang and Ch'à Ângsu. There are also commuter trains along the Ch'ongsuâÂÂSup'ungâÂÂP'ungnyà Ân (6 pairs), Kusà ÂngâÂÂPaegun (5 pairs) and Chà ÂngjuâÂÂKusà Âng (2 pairs) sections of the line.
