Seoul Station is the country's transport hub where KTX, regular trains, Subway Lines 1 and 4, and the Airport Railroad meet in central Seoul. The old station building, constructed in 1925, now operates as Culture Station Seoul 284, a space for exhibitions and performances. Lotte Mart, a food court, and cafes are connected to the station, and you can wait on the upper floors. On weekends, lines form at the restaurants.
