Korea's high-speed trains make day-trips and multi-city itineraries easy — Seoul to Busan is roughly 2.5 hours. Two operators run the lines; here's how to pick, book, and board.

KTX (Korail) departs central Seoul Station; SRT departs from Suseo in the southeast of Seoul. Both are high-speed and similar in price and time — pick by which departure station is closer to you.

Book in the app or online
Use Korail's 'Korail Talk' app or site for KTX, and the SRT app/site for SRT. Both have English booking and e-tickets. Reserve ahead for weekends and holidays.
