Suseo Station is an SRT high-speed rail hub connecting Gangnam and Songpa in Seoul and Seongnam in Gyeonggi to other regions. Trains run to Busan and Gwangju, with the first high-speed train to Busan departing at 5:30 a.m. The station has convenience stores and shops selling gimbap and sandwiches, and it connects to Subway Line 3 and the Suin-Bundang Line. Tickets are hard to get on weekends and during popular hours, so they must be booked in advance.
