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.
Tanks of South Korea
Despite the initial plan of a unified Korea in the 1943 Cairo Declaration, escalating Cold War antagonism between the Soviet Union and the United States eventually led to the establishment of separate governments, each with its own ideology, leading to Korea's division into two political entities in 1948: North Korea and South Korea. In the North, a former anti-Japanese guerrilla and communist activist, Kim Il-sung gained power through Soviet support. In the South, elections supervised by the United Nations were held, a Republic of Korea was declared, and Syngman Rhee inaugurated as its first president. In December, the UN General Assembly declared this "a lawful government" and "the only such government in Korea."
