The Sin Ansan 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.Since this line is still in the planning stages, there are many possible routes on which this line could be laid, with the only definite section between Sinpung and Gwangmyeong Station.
