The Pun'gang Line, also called the Nyŏngbyŏn Line, is a non-electrified railway line of the Korean State Railway in Nyŏngbyŏn County, North P'yŏngan Province, North Korea, running from P'arwŏn on the Ch'ŏngnyŏn P'arwŏn Line to Pun'gang.

[1] This line serves the Nyŏngbyŏn Nuclear Scientific Research Centre, located just south of Pun'gang Station.

The line was opened sometime between 1965, when a Soviet-supplied research reactor was put into service on the research centre site,[2] and 1980, when construction of an experimental reactor was begun.
