The Osich'à Ân Line was a non-electrified railway line of the Korean State Railway in Unhà Âng County, Ryanggang Province, North Korea, running from Taeoch'à Ân on the Paektusan Ch'à Ângnyà Ân Line to Osich'à Ân.
The branch line to Kim Jong-un's private railway station, called "Hyesan No. 1 Station", diverges from the main line of the Paektusan Ch'à Ângnyà Ân Line at almost the same point as the Osich'à Ân Line.
This Osich'à Ân Line was opened by the Chosen Government Railway on 1 November 1937, at the same time as the PongduriâÂÂHyesanjin section of the Kilhye Line.
A yellow background in the "Distance" box indicates that section of the line is not electrified.
