The Gyeongin and Gyeongbu Lines separate at this station, with the former going west and the latter south. In addition, the Line 1 train service depot is located south of the station between Guro and Gasan Digital Complex Stations; several tracks diverge and lead to the depot.
All non-metro trains such as KTX, ITX-Saemaeul, Saemaeul-ho, Mugunghwa-ho, and Nuriro pass without stopping at Gyeongbu Line B (Seoul Station to Cheonan Express). Trains from Incheon Station and Shinchang Station and trains bound for Incheon and Shinchang are joined and diverted, with all trains on Line 1 in the Seoul metropolitan area except Gyeongbu Line B stopping, and some trains use the station as a city and destination.
