The Ch'à Ângnyà Ân P'arwà Ân Line is a non-electrified standard-gauge secondary railway line of the Korean State Railway in North P'yà Ângan Province, North Korea, running from Kujang on the Manp'o and P'yà Ângdà Âk Lines to Kusà Âng on the P'yà Ângbuk Line.
This line serves the Nyà Ângbyà Ân Nuclear Scientific Research Centre via the Pun'gang Line, which joins the mainline at P'arwà Ân.
A line from Tà Âkch'à Ân to P'arwà Ân had been planned already in the 1940s by the West Chosen Central Railway, after receiving permission from the Railway Bureau of the Government-General of Korea in 1940 to extend its line beyond Tà Âkch'à Ân. However, by the end of the war, construction had been completed only as far as Changsangri (today on the Changsang Line), although work had begun on the line towards Kujang; it was only in 1953 after the end of the Korean War that the Tà Âkp'al Line to P'arwà Ân (the line's name came from the two termini, Tà Âkch'à Ân and P'alwà Ân) via Kujang was finally completed. The line was then extended further, reaching Kusà Âng in 1976. Although by then the line ran KujangâÂÂKusà Âng and the Tà Âkch'à ÂnâÂÂKujang section had been made part of the P'yà Ângdà Âk Line, it retained the "Tà Âkp'al Line" name until then.
Local passenger trains 795/796 operate on this line between Kujang Ch'à Ângnyà Ân and Kusà Âng.
A yellow background in the "Distance" box indicates that section of the line is not electrified.
