Seoul Subway Line 1
Line 1 of the Seoul Metropolitan Subway is a commuter rail service which links central Seoul, South Korea to Soyosan Station in the northeast, Incheon in the southwest, and Sinchang via Suwon and Cheonan in the south. The central underground portion of this rail line is the oldest subway section in the Seoul Metropolitan Subway system; the entire rail line covers a large part of the Seoul Capital Area. 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. 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. 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. Commuter railway service was extended to Sinchang in December 2008.

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.
In June 2006, Jinwi and Jije Stations opened on the Gyeongbu Line. In January 2010 Dangjeong Station opened, between Gunpo and Uiwang Stations. Part of the Gyeongwon Line from Dongducheon (formerly Dongan) to Uijeongbu was merged into Line 1 in December 2006.
The line runs on the left-hand side of the track, as opposed to the right-hand side of the track like all of the other Seoul Metropolitan Subway lines do. (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)
As written on the table to your left, it is 200.6 km including all branches, which will mean that the line is the longest subway line in the world (verification needed)
Rapid (Express) trainsEdit
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:
