The Namhà Âng Line is an electrified standard-gauge secondary line of the Korean State Railway in South P'yà Ângan Province, North Korea, running from Maengjungri on the P'yà Ângà Âi Line to Namhà Âng.
A maintenance facility for the diesel shunting locomotives that move freight cars between Namhà Âng Station and the chemical complex was opened just east of the station in 2009-2010.
The line was opened by the Korean State Railway in 1976 to serve the Namhà Âng Youth Chemical Complex. The line was electrified sometime between 2006 and 2010.
Though the bulk of the freight traffic on this line is to and from the chemical complex, it also serves the Anju No. 121 Paper Factory located just west of the chemical complex.
Within the Namhà Âng Youth Chemical Complex itself, the sodium bicarbonate plant, the urea fertiliser plant, the polyethylene sheeting plant, a tank farm for storage of liquid chemicals, and the polyester spinning factory are all served by rail. The anthracite gasification plant which was opened in 2013 is also rail-served, receiving anthracite coal for processing via a dedicated railyard.
