Daegok station () is a station on Seoul Subway Line 3, Seoul Subway GTX-A Line, the GyeonguiâÂÂJungang Line and the Seohae Line. It is located in Goyang, Gyeonggi Province, South Korea. It is mainly used as a transfer station between the four lines rather than as an actual enter-and-exit stop, as the station is located in the midst of farmland with very little local resident demand.
It hosted a third line for transfer, as the Seohae Line was built and brought northward on July 1, 2023. This now allows for much faster, direct subway travel between Ilsan, Gimpo Airport, Bucheon, Siheung, and Ansan.
Effective December 28, 2024, the platforms for the GTX-A higher speed commuter rail line began operation.
