The Chamjilli Line is a non-electrified freight-only railway line of the Korean State Railway in South P'yà Ângan Province, North Korea from Kangsà Ân on the P'yà Ângnam Line to Chamjilli.
The line serves several above-ground factories and the Namp'o Kangsà  Missile Factory, which is an underground facility with a rail spur entering the underground complex. In the past there was also a section leading to another (now closed) factory, and to the Kangsà  Colliery.
A yellow background in the "Distance" box indicates that section of the line is not electrified.
