Park also stated her hope that the remaining 2.4 km (1.5 mi) section across the DMZ would be rebuilt soon, which would re-establish the old Kyŏngwŏn Line connecting Seoul to Wŏnsan.

[9] Electrification of the Pokkye−Kosan section of the Kyŏngwŏn line began in December 1940; it was completed and commissioned on 27 March 1944,[10] and commercial electric operations commenced on 1 April 1944.

[2] The Kangwŏn Line serves the ports at Wŏnsan and Munch'ŏn, and a number of industries including the smelter at Munch'ŏn and the May 18th Works; the primary goods received on the line are anthracite, zinc concentrates, coke, solvents etc., while the most important outbound goods include seafood and machinery.

There is also a significant amount of through traffic on the line destined for points in North and South Hwanghae on the Ch'ŏngnyŏn Ich'ŏn line and beyond, such as coking coal imported from China for the Hwanghae Iron & Steel Complex, wood imported from Russia and chemical fertilisers produced in the Hamhŭng area.

[2] At Kalma is located the 4 June Rolling Stock Works, the DPRK's largest manufacturer of railway freight and passenger cars.
