Sinansan Line

The Sinansan Line (Hangul: 신안산선, Hanja: 新安山線, meaning "New Ansan Line") is the tentative name of a commuter rail line that will eventually link Cheongnyangni station with western Gyeonggi province, passing through key areas of the Seoul metropolitan area, including Yeouido, Yeongdeungpo and Gwangmyeong station.

In particular, the section south of Gwangmyeong station has led to heated disputes between the cities of Ansan and Siheung.

Ansan has requested for the line to be built almost perfectly south from Gwangmyeong station so it terminates at Hanyang Univ.

Construction was planned to begin in 2015 with the first section of this line (Gwangmyeong station - Yeouido) is set to be opened in 2023.
