GTX-A Commuter Line: Revolutionizing Seoul’s Transportation Network

In a significant leap forward for Seoul’s transportation infrastructure, the Great Train Express (GTX) commuter rail line is set to inaugurate its first leg, GTX-A, marking a milestone in intercity connectivity. This new commuter line aims to seamlessly link Seoul with its neighboring cities in Gyeonggi and Gangwon Province, heralding a new era of convenience for commuters and travelers alike.

The Inaugural Journey

The inaugural leg of the GTX-A will commence operations on Saturday, promising efficient connectivity between Seoul’s Suseo Station and Dongtan Station in Hwaseong, Gyeonggi Province, spanning a distance of 34.9 kilometers. Departing from Suseo Station at 5:30 a.m., the GTX-A’s maiden voyage will embark on a journey towards enhancing regional accessibility and commuting options.

Enhanced Connectivity

With trains operating at 20-minute intervals, commuters can enjoy frequent and reliable services throughout the day. During peak hours, the intervals are further reduced to 17 minutes, catering to the bustling demands of daily commuters. While currently stopping only at Seongnam Station along the route, future expansions are planned, including the integration of Guseong Station into the GTX-A network by June.

Streamlined Commutes

Commuting between Suseo and Dongtan will be transformed from a time-consuming endeavor to a swift, stress-free experience. With an estimated travel time of just 20 minutes, the GTX-A offers a compelling alternative to congested roadways and lengthy bus journeys. This remarkable reduction in travel time not only enhances efficiency but also contributes to a more sustainable mode of transportation.

Fare Structure

While the GTX-A presents an unparalleled solution for urban mobility, it comes with a fare structure that reflects its premium services. With a basic fare of 3,200 won ($2.40) for the first 10 kilometers, passengers will incur additional fees of 250 won per five kilometers beyond this initial distance. Despite being the priciest urban rail transit system in South Korea, the GTX-A’s superior convenience and time-saving benefits make it a worthwhile investment for commuters.

Discounted Options

Recognizing the importance of affordability, transportation authorities have devised discount schemes to incentivize frequent usage of the GTX-A. The introduction of the K-Pass discount service, slated for launch on May 1, promises significant fare reductions, potentially lowering costs for the Suseo-Dongtan section to between 2,000 and 3,000 won. These initiatives aim to make the GTX-A accessible to a wider demographic while ensuring that cost remains a minimal barrier to its utilization.

Future Prospects

As the inaugural route of the GTX network, the GTX-A sets the stage for future expansions and developments. Transit authorities envision a comprehensive network comprising lines B to F, seamlessly connecting Seoul with key cities in Gyeonggi and Gangwon Province. Upon completion, the GTX network will revolutionize regional connectivity, facilitating efficient travel between urban centers and suburban locales.


The launch of the GTX-A commuter line represents a significant leap forward in Seoul’s transportation landscape, promising enhanced connectivity, streamlined commutes, and unparalleled convenience for residents and visitors alike. As the first step towards a comprehensive network of intercity commuter lines, the GTX-A embodies the vision of a modern, integrated transportation system, setting new standards for urban mobility in South Korea.
