Example Input: Question: How much distance was between Kyongwon Line and Ch'osongri? Passage:After the partition of Korea following the end of the Pacific War, the Kyongwon Line was split along the 38th parallel between the stations of Hantangang and Ch'osongri, and the Korean State Railway, established following the nationalisation of all railways in North Korea in 1946, merged the truncated WonsanCh'osongri section of the Kyongwon Line with the WonsanKowon section of the former Hamgyong Line to create the Kangwon Line. Following the end of the Korean War and the establishment of the Military Demarcation Line, the section south of Woljongri ended up in South Korea, where the Korean National Railroad reabsorbed it into the Kyongwon Line. The section from P'yonggang to Kagok has been closed since the end of the war, and since then the line has its current name, from the two termini: P'yonggang and Wonsan. The line was severely damaged during the Korean War, but was quickly repaired after the war. The KowonSep'o Ch'ongnyon section of the line was electrified in September 1980, and the electrification of the Sep'o Ch'ongnyonP'yonggang section was completed in early 1986.
