Oido station is a subway station on Seoul Subway Line 4 and the Suin–Bundang Line in Siheung, South Korea. It is the current southwestern terminus of Seoul Subway Line 4 located almost 30 kilometers southwest of Seoul, connecting Oido to other parts of Korea. A commuter rail trip between this station and Seoul Station takes over an hour, and a train servicing depot is located nearby. The name of the station was decided by the surrounding area Oido island. This station, along with Jeongwang station to the southeast, serves the Sihwa Industrial District of southwestern Siheung. Beginning in June 2012, this station also became the southeastern terminus of the Suin Line, linking the city of Siheung to southern Incheon. The Suin Line was later connected to the Bundang Line, allowing for service directly into Seoul, combining the two lines as the Suin–Bundang Line. Trains on Seoul Subway line 4 and the Suin–Bundang Line share tracks and platforms through this station as well as along a significant portion of the Ansan Line; trains on Line 4 end service here. Of the 4000 trains of the Seoul Metro that run between Danggogae and Oido, 450 and 471 & 481 and 485 trains and the 341000 trains of the Korea Railroad Corporation will end at the station.

Suin Line and future plans

The narrow-gauge Suin Line, which served as a means of transporting freight between Suwon and Incheon, was abandoned in 1995. Oido Station is the northwestern terminus of the section of the Suin Line that is still in use today; the southeastern terminus is Hanyang University at Ansan Station. However, with the recent population boom in southern Gyeonggi province, the line was relaid as a standard gauge railroad for commuter rail. The commuter rail was opened over the course of a few stages. The first stage incorporates an extension of the Suin Line into southern Incheon, and will transfer with the Incheon Subway Line 1 at Woninjae Station.
