The underground section between Seoul Station and Cheongnyangni Station, which is referred to as Seoul Metro Line 1 (7.8 kilometers [4.8 mi]), is currently operated by Seoul Metro.[1] The line first opened in 1974 as the '''Korean National Railroad of Seoul''' with through services to national mainline railways from Seongbuk Station (now: Kwangwoon University Station) to Incheon and Suwon Stations.[2] At the time, the 7.8 km underground portion was run by Seoul Metro was called Line 1 and labeled red on maps. On the other hand, the remaining sections of the rail line run by Korail were labeled either blue or gray on maps, and the express lines were red. In 2000, the adjacent through-running Korail services from the Gyeongbu, Gyeongin and Gyeongwon Lines were officially bundled together as part of a greater Line 1, and the labeling on maps was changed to the current dark blue color.

Frequent service is provided between Soyosan, Dongducheon, Uijeongbu, Cheongnyangni, Seoul, Yongsan, and Guro, where trains split between Incheon in the west and Byeongjeom and Cheonan in the south. Express trains operate from Yongsan and Seoul Stations to Dongincheon and Sinchang stations. Trains run every 3-6 min in the central route between Seoul Station and Cheongnyangni, every 6-9 min between Seoul and Guro, every 8-10 min between Guro and Incheon and between Guro and Byeongjeom, every 10-15 min from Byeongjeom to Cheonan, and every 35 min between Cheonan and Sinchang and service up to the Dongducheon area and Soyosan station

Trains travel along Gyeongbu (Seoul-Cheonan), Gyeongin (Guro-Incheon), Janghang (Cheonan-Sinchang), and Gyeongwon (Hoegi-Soyosan) railway lines. The line runs on the left-hand side of the track, as opposed to the right-hand side of the track like all other Seoul Metropolitan Subway lines (another exception to this is Seoul Subway Line 4 although it runs on the right-hand side until Namtaeryeong station, and operates on the left-hand side for the parts afterwards)[3] since railways in Korea generally run on the left side.

Rapid (Express) trains

Korail operates a variety of express "rapid" (급행, 急行) trains for long distance commuter services on Line 1. These services include:

  • Gyeongin line express services from Yongsan to Dongincheon, operating express between Guro and Dongincheon, including:
    • Regular express services, introduced on January 29, 1999, following quadruple-tracking of the Gyeongin Line.
    • Faster limited express (특급) trains, introduced on July 7, 2017.
  • Red Gyeongbu line express services from Cheongnyangni to Cheonan or Sinchang, operating express between Gasan Digital Complex and Cheonan and running local elsewhere.
  • Green Gyeongbu line express service from Seoul Station to Cheonan or Sinchang, originating at a platform adjacent to Seoul Station, skipping all stations between Seoul Station and Geumcheon-gu Office Station, making intermediate stops at Anyang, Gunpo, Uiwang, and Sungkyunkwan University, and then following the red Gyeongbu line express service pattern south of Suwon. Northbound services (departing from Cheonan/Sinchang and terminating at Seoul Station) stop at Yeongdeungpo Station, but southbound services are unable to due to the lack of a raised platform. This service was introduced on September 25, 1982.[4]
  • Gyeongwon line express services from Dongducheon (although several trains originate from Soyosan) to Incheon, operating express between Dongducheon and Kwangwoon University and running local between Incheon and Kwangwoon University.

Former express services include:

  • One late night Gyeongin line express service that originated at Soyosan, made all stops to Guro, then made express stops until Incheon.
  • Yeongdeungpo-Byeongjeom Gyeongbu line express service, skipping all stations between Yeongdeungpo and Anyang and then following the Yeongsan-Cheonan/Sinchang express service pattern south of Anyang until Byeongjeom. This service was introduced on August 25, 2014 and was discontinued on December 9, 2016.
  • Two faster Yongsan-Sinchang limited express trains (one in each direction), introduced in 2013. This train only operated on weekends and holidays. It was discontinued on July 1, 2018.

Electric current

Seoul Subway Line 1 is powered by 1500 V direct current between Cheongnyangni station and Seoul station, and by 25000 V alternating current elsewhere. Because of this different manner of offering electric current, there are neutral sections between Cheongnyangni station and Hoegi station, as well as between Seoul Station and Namyeong station.
