Editing Gyeongui Line (section)

===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.
