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.
North Korea
In 2018, a détente developed. On 27 April, a 2018 inter-Korean summit took place between President Moon Jae-in of South Korea and Kim on the South Korean side of the Joint Security Area. It was the first time since the Korean War that a North Korean leader had entered South Korean territory. On 12 June 2018, the first meeting between North Korea's leader, Kim Jong-Un, and US President, Donald Trump, occurred in Singapore. In September, at a summit with Moon in Pyongyang, Kim agreed to dismantle North Korea's nuclear weapons facilities if the United States took reciprocal action.
