What is the Busan to Seoul Train Service?
The Busan to Seoul train service primarily operates through Korea’s high-speed rail system called KTX (Korea Train Express), which is managed by Korail, the national railway operator. KTX trains travel at speeds up to 300 km/h on dedicated high-speed tracks, connecting Busan Station in the south to Seoul Station in the capital region.

Therefore, most travelers choose KTX for business or time-sensitive trips, while budget-conscious passengers opt for ITX-Saemaeul.
