The Map'yà Âng Line is a non-electrified railway line of the Korean State Railway in T'aech'à Ân County, North P'yà Ângan Province, North Korea, running from P'arwà Ân on the Ch'à Ângnyà Ân P'arwà Ân Line to Hwà Ânhwa.
The line formerly continued from Hwà Ânhwa to past the site of the T'aech'à Ân nuclear reactor, but that section was abandoned after construction of the reactor was halted in 1994; the line had also continued further on to Map'yà Âng to assist with the construction of the large Taech'à Ân No. 2 Hydroelectric Power Station further up the Taeryà Âng River.
A yellow background in the "Distance" box indicates that section of the line is not electrified.
