The Suin Line (Suwon-Incheon; Korean: 수인선) was a metro line of the Seoul Metropolitan Subway serving the Seoul Capital Area.

The original route, abandoned in 1995, was one of the few 762 mm (2 ft 6 in) narrow-gauge railways in South Korea. Opened by the privately owned Chosen Gyeongdong Railway in 1937, it connected Suwon to Namincheon via Ansan and Siheung; in 1942, it was taken over by another private railway, the Chosen Railway (the largest of colonial Korea's privately owned railway companies). The Chosen Railway owned the line until all railways in Korea were nationalized after 1945. However, since December 28, 2004, the Suin Line is being reconstructed with standard gauge and double tracking as an integral part of the Seoul Metropolitan Subway network and is opening in three phases.^[2]

All northbound trains terminated at Incheon, all southbound services terminated at Oido. Express train service served only Oido, Soraepogu, Incheon Nonhyeon, Woninjae, Yeonsu, Inha University, and Incheon.^[3]

Trains along the line were 6 cars long. Platforms at stations are built for 8 cars in preparation for the merging of the Bundang Line with the Suin Line, and are prepared for 10 cars when the extension occurs.

Trains run at an interval of 15 minutes throughout the day.
