Gyeongui Line (1904–1945)
Following Japan's defeat in the Pacific War and the subsequent partition of Korea, the Gyeongui Line was divided at the 38th parallel between North and South Korea. On 25 August 1945, the Soviet Army began operating trains on the line north of Sariwon, whilst trains in the south terminated at Gaeseong. In 1946, the railways in both North and South were nationalised, creating the Korean National Railroad in the South and the Korean State Railway in the North. After the Korean War, the Gyeongui Line was split into three sections. In the South, the Seoul–Jangdan section became the KNR's Gyeongui Line, retaining the same name; in the North, the Bongdong–Pyeongyang section became the P'yŏngbu Line, whilst the Pyeongyang–Sinuiju section became the P'yŏngŭi Line.
Foreign relations of North Korea
In August 1971, both North and South Korea agreed to hold talks through their respective Red Cross societies with the aim of reuniting the many Korean families separated following the division of Korea after the Korean War. After a series of secret meetings, both sides announced on 4 July 1972, an agreement to work toward peaceful reunification and an end to the hostile atmosphere prevailing on the peninsula. Dialogue was renewed on several fronts in September 1984, when South Korea accepted the North's offer to provide relief goods to victims of severe flooding in South Korea.
