KTX vs ITX: Which One to Choose?
In this guide, we’ll break down KTX vs ITX in terms of speed, cost, routes, amenities, booking, and overall experience, helping you decide which train service is right for your journey.
South Korea’s Rail Network
South Korea boasts one of the most advanced rail systems in Asia, connecting major cities like Seoul, Busan, Daejeon, and Gwangju. Operated primarily by Korail, the network includes the KTX Korea Train Express, known for its high speed trains that can reach speeds of up to 330 km/h, as well as the ITX trains (such as the popular ITX-Saemaeul) that provide a slightly slower but still efficient option. For long distance travel, KTX trains running on the Gyeongbu Line and Honam Line offer the fastest way to move between Seoul and other destinations, including Busan and Mokpo, in just a few hours.
KTX: High-Speed Champion
The Korea Train Express (KTX) is the country’s flagship bullet train, capable of reaching speeds up to 330 km/h (205 mph). It’s the fastest and most convenient choice for long-distance journeys, especially between Seoul and Busan, which takes just over 2.5 hours compared to more than 5 hours by car.
KTX operates across four main lines, all radiating from Seoul:
Honam Line: Seoul – Mokpo, covering western destinations.
Gyeongjeon Line: Seoul – Changwon and Jinju.
Jeolla Line: Seoul – Suncheon, with stops like Jeonju.
Gyeongbu Line: Seoul – Busan via Suwon, Daejeon, Daegu, and Ulsan.
