The Great Train eXpress (GTX) is a new concept of high-speed train service in the Seoul Capital Area, designed to improve transport welfare of metropolitan residents and alleviate chronic congestion by connecting key areas in the outskirts of the capital with the city center in 20 minutes. The existing
subway lines operate at the speed of 30~40km/h, around 20m underground, but the GTX operates deeper underground of around 40~50m, at the maximum speed of 180km/h in straight routes.
