# Suin–Bundang Line

The Suin–Bundang Line (Suwon–Incheon–Bundang Line) is a commuter rail service of the Seoul Metropolitan Subway system, operating on trackage from the Suin Line (opened on June 30, 2012) and the Bundang Line (opened on September 1, 1994). Operation began on September 12, 2020.
Frequent service is provided between Wangsimni and Incheon by 6-car trains, with 9 trains on weekdays and 5 on weekends running one station north of Wangsimni to Cheongnyangni. However, many trains terminate at various locations on the line such as Jukjeon, Gosaek, and Oido.
Trains travel along the Suin (Incheon-Suwon), Bundang (Suwon-Wangsimni), and Gyeongwon (Wangsimni-Cheongnyangni) lines. It shares trackage with the Ansan Line of Seoul Subway Line 4 between Hanyang University at Ansan and Oido.
Like all other Korail-run Seoul Metropolitan Subway lines, trains on the line run on the left-hand side of the track.
