===Seoul Metropolitan Subway===
{{main|Gyeongui–Jungang Line}}
The Gyeongui Line opened as a part [[Seoul Metropolitan Subway]] on July 1, 2009 from [[Seoul Station|Seoul]] to [[Munsan station|Munsan]]. The line connects [[Seoul]], [[Digital Media City]], [[Ilsan]], [[Paju]], and [[Munsan]], and offers transfers to [[Seoul Subway Line 3|Line 3]], [[Seoul Subway Line 6|Line 6]], and [[AREX]].

The main line terminated at [[Digital Media City Station]] when first opened, while a separate branch continued to Seoul Station. On December 15, 2012, the main line was extended to [[Gongdeok Station]], providing transfers to [[Seoul Subway Line 6|Line 2]] and [[Seoul Subway Line 5|Line 5]]. On December 27, 2014, the main line service was further extended to [[Yongsan Station]] from Gongdeok Station, and the service was renamed to the '''Gyeongui–Jungang Line''' following the merging of the line with the [[Jungang Line]].

The term "subway" in reference to this line is somewhat of a misnomer, as the line runs underground for less than three percent of its length. The upgraded line simply follows alignment of the old line built 100 years ago. The outer portion of the line runs largely through countryside rice paddies, forests, and vegetable fields, and outside of Seoul rarely enters urbanized areas. It is mostly at-grade, and includes several at-grade crossings with local roads, where Korail employees stand by on duty to stop traffic.

===Regular rail service===
Before the integration with the subway system, the most common service on the line was a [[Tonggeun]] train service between Seoul and Imjingang, with one [[Saemaeul-ho]] train. Since the line was integrated with the Seoul Subway system, Tonggeun service had been restricted to a few stations in the north, from Munsan to Imjingang, with a few continuing on to Dorasan, near the North Korean border.

===KTX===
There is a depot for [[Korea Train Express]] (KTX) trains along the Gyeongui Line at [[Haengsin station]].<ref name="LaunchHSR2007">{{cite journal |last=Lee |first=Kyung Chul |url=http://www.jrtr.net/jrtr48/pdf/f30_Lee.pdf |title=Launch of Korean High-Speed Railway and Efforts to Innovate Future Korean Railway |journal=Japan Railway & Transport Review |issue=48 |pages=30–35 |date=August 2007 |access-date=2010-10-23 |archive-url=https://web.archive.org/web/20110613154854/http://www.jrtr.net/jrtr48/pdf/f30_Lee.pdf |archive-date=2011-06-13 |url-status=dead }}</ref> Some KTX services thus continue beyond Seoul respective Yongsan Station and terminate at [[Haengsin station]].<ref name="booking">{{cite web |url=http://www.korail.com/en/rv/pr21100/w_pr21110.jsp |title=Booking |publisher=[[Korail]] |access-date=2010-10-18 |url-status=dead |archive-url=https://web.archive.org/web/20110713164814/http://www.korail.com/en/rv/pr21100/w_pr21110.jsp |archive-date=2011-07-13 }}</ref>

The line may see more KTX service after the upgrade for 230&nbsp;km/h considered in the government's strategic plan for 2020.<ref name="plans2020"/>
