Ilsan Line is asubway line operated byKorail, in Seoul, South Korea. Trains from this line continue to and fromSeoul Metro'sLine 3.^[2]

The line started construction on March 15, 1991 as an extension of Seoul Metro Line 3 with the line opening in 1996. After the completion of the Ilsan Line, the Korean National Railroad suddenly announced that it would transfer ownership of the line toSeoul Metropolitan Government. According to theKorea National Railway, the Seoul Metropolitan Government asked theSeoul Metropolitan Subway to take over the operation of the Ilsan Line, which is connected to the Seoul Subway Line 3, noting that redundant management facilities and workforce would be needed if Korean National Railroad operates the Ilsan Line. The Seoul Metropolitan Government dismissed the request because the Ilsan Line was located inGyeonggi Province, and was concerned the increased expenditure shouldSeoul Metropolitan Subway operate the line.^[3] Ultimately, the Ilsan Line remained under the jurisdiction of the Korean National Railroad which became what is todayKorail. On December 27, 2014Wonheung station started operation.^[4]

For the opening of the Ilsan Line, Korea National Railway procured a fleet of 18 first-generationKorail 3000 series trainsets fromHyundai Precision & Industries, delivered from 1995–1997. A fleet of eight second-generation Korail 3000 series trainsets are currently being manufactured byHyundai Rotem, and another eight third-generation Korail 3000 series trainsets will be manufactured byWoojin Industrial Systems, both to eventually replace the first-generation trains. All Ilsan Line trains operated by Korail are stored and maintained at Jichuk Depot located near Jichuk Station.
