The Suin Line (Suwon-Incheon; {{Korean|hangul=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 {{Track gauge|762mm|lk=on}} 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.{{Cite web|url=https://terms.naver.com/entry.nhn?docId=559077&cid=46632&categoryId=46632|title=Suin Line|last=|first=|date=|website=EncyKorea|archive-url=|archive-date=|access-date=}}

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.{{Cite news|url=http://news.joins.com/article/8640684|title=전철로 22분 … 이웃동네 된 송도~오이도|date=2012-07-03|work=JoongAng Ilbo|access-date=2018-04-12|language=ko-KR}}

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.

Rolling stock

The Suin Line used 18 Korail Class 351000 trains. They were the same as the third generation Class 351000 trains from the Bundang Line, except that they were painted red like the Gyeongui-Jungang Line and Line 1 trains. These trains have since been repainted yellow to match the color of Bundang Line trains; this was done in anticipation of the merging of the Bundang and Suin Lines into the Suin–Bundang Line.

For the former Suin Line, the Korean National Railroad built a narrow gauge steam locomotive, the KNR160 diesel car (also known as the Niigata/Kawasaki Diesel Car), and the KNR18000 passenger car. One KNR160 car (later renumbered KNR9160) and two KNR18000 car are preserved at the railroad museum in nearby Uiwang.
