The station is served by the Korail Intercity Lines and the commuter trains of the Seoul Metropolitan Subway.

Seoul Station is the terminus of most KTX trains including: Some KTX services operating along sections of the conventional Honam Line bound for GwangjuSongjeong, Mokpo and Yeosu Expo arrive and depart Yongsan Station.

[1] Seoul Station is the terminus of all ITX-Saemaeul trains along the Gyeongbu and Gyeongjeon Lines to Busan, Daejeon, Daegu, Pohang, Masan and Jinju.

[8] AREX Express passengers have exclusive access to Seoul Station's City Air Terminal which allows passengers travelling on most Korean airlines from Incheon Airport to check bags and receive boarding passes before boarding the train.

Yet having a rather complicated structure with many bus platforms, the transfer center is built in a simple manner as it is not a separate terminal building.

In 2004, a new terminal adjacent to the existing one was completed to coincide with the introduction of KTX high-speed rail service.

The official name, which combines the station's historic, spatial, and urban symbolisms, was selected through a national open call.

By combining the notion of a cultural space with the old Seoul Station's historic site number 284, the name aims to embody the concepts of preserving its appearance and value as a historic site while simultaneously cultivating the meaning of the station as a place of various cultural intersections.
