The Gyeongbu Line is the major route out of Seoul Station, and in addition to regular departures for Busan, trains travel along the Gyeongbu Line en route to Janghang, Gwangju, Mokpo, Suncheon, Yeosu, Pohang, Ulsan, Haeundae, Masan, and Jinju. Trains for Jecheon, Andong, and Yeongju also operate along sections of the Gyeongbu Line.
The most frequent passenger service on the line is provided by Seoul Subway Line 1 on the section between Seoul Station, Guro (where roughly half the subway trains leave the Gyeongbu Line to head out to Incheon via the Gyeongin Line), and Suweon.
The Gyeongbu Line is currently 6-tracked from Seoul to Guro, 4-tracked from Guro to Suweon, and double-tracked from Suweon all the way to Busan. The section from Suweon to Daejeon was being doubled to 4 tracks in the early 2000s.
