The Tŭkchang Line is an electrified railway line of the Korean State Railway in South P'yŏngan Province, North Korea, running from Pukch'ang on the P'yŏngdŏk Line to Sŏksan.

[1] The line was opened in 1961 to assist with the construction of the Pukch'ang Thermal Power Complex which began in that year.

[2] The important Pukch'ang Thermal Power Complex - the largest coal-fired power plant in the DPRK[3] - is located on this line at Yangch'on, receiving a great deal of coal from the mines in the area.
