Currently, the high-speed KTX and Super Rapid Train services that operate between the two cities take between two hours and 15 minutes and nearly three hours. The new non-stop service will reduce travel time to just under two hours. This could mean that door-to-door journeys by rail will be faster than flying, if airport transfers and security time are taken into account.
Prices for the new non-stop trains will start at ₩52,600 (£35). A sample one-way airfare, by comparison, would cost ₩135,530 (£92). If the services are successful, South Korea’s Ministry of Land, Infrastructure and Transport has said it may roll out non-stop services from Seoul to Gwangju and Mokpo in the southwest part of the country.
