The figures above cover only standard-seat KTX tickets for this station pair. Train-specific availability, first-class upgrades, other train types and local transfers are separate. Confirm the timetable and final ticket price with the operator before purchase.
What matters on this route
Seoul Station and Busan Station are the station pair priced here. Both connect to local metro networks, but the local ride to your accommodation is not part of the intercity ticket. If you are staying in southern Seoul, SRT from Suseo may be geographically convenient, but it is a different operator choice and is not covered by a KORAIL Pass.
This page deliberately avoids a fixed journey-time promise because stopping patterns and timetables vary. Use the official booking timetable for the exact departure you plan to take.
Tickets or a KORAIL Pass?
Seoul–Busan has a relatively high individual-ticket total, so it deserves to be entered first in a pass comparison. The decisive question is what else you will ride: a second long-distance day can change the result, while an uncovered SRT or local-transit leg cannot be counted as pass value.

Method: exhaustive deterministic candidate comparison with one pass at most per traveler/group. All displayed scenarios have high or medium data confidence. Unused journeys are never added as savings.
A route page cannot decide a pass from one leg alone. The calculator prices every journey, every eligible product and every legal Select-pass date combination, then includes uncovered tickets exactly once.
Before you book
- Enter both directions separately if you are returning to Seoul.
- Add Gyeongju, Daegu or other confirmed rail legs before comparing passes.
- Keep SRT and city transit outside KORAIL Pass coverage.
- Reserve the actual train after checking seat availability on your intended date.
