Editing Gyeongui Line (section)

After the [[division of Korea]] in 1945, trains stopped operating between the north and south halves of the country, meaning that southern trains probably terminated at [[Kaesong|Kaesŏng]], which is now in North Korea but was at the time part of the [[United States of America|US]]-administered southern zone. Northern trains would have terminated north of Kaesŏng.

After the end of the [[Korean War]] in 1953, southern trains were cut back to around [[Munsan]] (north of Seoul), with northern trains terminating at Kaesŏng. Around the same time, North Korea renamed the P'yŏngyang-Kaesŏng section of the line as the [[Pyongbu Line|P'yŏngbu]] (''P'yŏng''yang + ''Bu''san) Line and the P'yŏngyang-Sinŭiju section as the [[Pyongui Line|P'yŏngŭi]] (''P'yŏng''yang + Sin''ŭi''ju) Line. The DPRK sector is now 100% electrified, although the double track section spans only from [[Pyongyang]] to [[Pyongyang Sunan International Airport|Sunan Airport]].

Since the summit between the two Koreas in 2000, an effort has slowly been underway to reconnect the Gyeongui Line.<ref name="TransKorea">{{cite journal |url=http://www.irail.net/webzine/krt/20071008/15356_cf_171_KRT_9.pdf |title=Trans-Korean Railway |journal=Korean Rail Technology (English) |volume=9 |pages=09–11 |date=September 2007 |access-date=2010-11-04 |archive-date=2018-07-14 |archive-url=https://web.archive.org/web/20180714221847/http://www.irail.net/webzine/krt/20071008/15356_cf_171_KRT_9.pdf |url-status=usurped }}</ref> Southern passenger service has been extended to [[Dorasan]] on the edge of the [[Korean Demilitarized Zone|Demilitarized Zone]] (DMZ) and tracks have been built across the DMZ itself.
