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.
