Suseo Station is a large railway station in the Gangnam area of Seoul where riders transfer between the SRT, Line 3, and the Suin-Bundang Line. The SRT and subway platforms connect directly underground, linking to high-speed rail toward Busan and to buses. Because it is a starting and ending station, passengers who arrive early can board a waiting train in advance, and a Climate Card charging station sits near the Line 3 ticket gates. Seating in the waiting area is limited.
