The Gyeongin Line was the first railway line built on the [[Korean peninsula]]. It was opened by the [[Gyeongin Railway|Keijin Railway Company]] between [[Noryangjin station|Noryangjin]], on the shore of the [[Han River (Korea)|Han River]] across from Seoul, [[Geumchon station|Geumchon]], in [[Incheon]], on September 18, 1899.<ref name="lineop">{{cite web |url=http://info.korail.com/2007/kra/ope/ope08000/w_ope08606.jsp |title=경영원칙 > 경영공시 > 영업현황 > 영업거리현황 |publisher=[[Korail]] |access-date=2010-11-27 |url-status=dead |archive-url=https://web.archive.org/web/20110722192217/http://info.korail.com/2007/kra/ope/ope08000/w_ope08606.jsp |archive-date=2011-07-22 }}</ref> Soon after, the line was extended across the Han River into [[Seoul Station]], and beyond Geumchon to the port of Incheon. When the construction of the [[Gyeongbu Line]] was completed from [[Busan station|Busan]] to Guro on January 1, 1905, the Seoul-Guro section of the Gyeongin Line became part of the Gyeongbu Line.<ref name="lineop"/> The remaining Gyeongin Line from Guro to Incheon is {{convert|27.0|km|mi|1|abbr=on}} long.<ref name="lineop"/>

Following the 1961 coup, the [[Supreme Council for National Reconstruction]] started South Korea's [[Five-year plans of South Korea#1962–1966|first five-year plan]], which included a construction program to complete the railway network, to foster economic growth.<ref name="5yr-plan">{{cite web |url=http://www.silvernetnews.com/?inc=newsview&no=8229&s=20&ss=0&sss=0 |title=<nowiki>철마 110년, 영고의 자취 [12] 경제개발과 철도</nowiki> |language=ko |date=2010-03-20 |publisher=Silvernet News |access-date=2010-11-30}}</ref> As part of the program, from November 1963, two additional tracks were laid to the north of the existing tracks from [[Yeongdeungpo station]] on the Gyeongbu Line to [[Dongincheon station]].<ref name="5yr-plan"/> The {{convert|27.8|km|mi|abbr=on}} of new tracks, also called Gyeonginbuk Line, entered service on September 18, 1965.<ref name="5yr-plan"/>
