The Tŏkhyŏn Line was opened by the Korean State Railway in April 1971.
The primary function of the Tŏkhyŏn Line is to deliver iron ore from the mines around Tŏkhyŏn to the September Iron & Steel Complex (9월제철종합기업소) in Sinŭiju and the Hwanghae Iron & Steel Complex on the Songrim Line, thus the bulk of southbound freight is ore from the mines.
A yellow background in the "Distance" box indicates that section of the line is not electrified.
