Suseo Station

Suseo Station (Korean: 수서역; Hanja: 水西驛; RR: Suseo-yeok) is a railroad station on the Suin–Bundang Line and Line 3 of the Seoul Metropolitan Subway. The station is in the Suseo neighborhood of the Gangnam District in Seoul, South Korea. Prior to the Line 3 extension to Ogeum station in 2010, Suseo Station was the southeastern terminus of Line 3. Along with Yangjae station, Suseo Station serves as an important transfer point between Line 3 and buses from/to southern cities such as Seongnam, Yongin, and Suwon. In December 2016, it became the northern connection point to the Suseo–Pyeongtaek high-speed railway running SRT. On 30 March 2024, Suseo Station became the northern terminus of the first phase of Line A of the GTX. From this station, the GTX travels south and shares tracks with the SRT on the right-of-way inside the Yulhyeon tunnel and Suseo–Pyeongtaek high-speed railway. The platforms of the GTX are separate from those of the SRT. In the future, Bundang Line station plans to install evacuation lines on the platform as part of the express train operation. The Suseo Pyeongtaek Express Line is an underground section from this station to Dongtan station.
