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.
K-pop
After the Korean Peninsula was partitioned into North and South following its liberation in 1945 from Japanese occupation, Western culture was introduced into South Korea on a small scale, with a few Western-styled bars and clubs playing Western music. After the Korean War (1950–53) U.S. troops remained in South Korea. With the continued presence of the U.S. military during this time, American and world culture spread in South Korea and Western music gradually became more accepted.
