The 30-second answer
| Question | Answer |
|---|---|
| How long? | About 2 h 18 min on the fastest KTX, up to about 2 h 56 min on trains with more stops |
| How much? | ₩59,800 one way, standard class, adult. The same price on fast and slow trains |
| From where? | Seoul Station (KTX) to Busan Station. SRT trains leave from Suseo in south-east Seoul |
| Korail Pass? | Not for a simple return: Seoul–Busan–Seoul costs less than the 2-day pass |
1. Pick the fastest train: it costs the same
Korail charges ₩59,800 for Seoul–Busan whatever the number of stops, so a train that takes 2 h 56 min costs the same as one that takes 2 h 18 min. When you book, compare the journey times on the list and pick the shortest one that suits you.
2. KTX or SRT?
- KTX (Korail) leaves from Seoul Station. The airport railroad (AREX) from Incheon Airport also ends at Seoul Station, so it is the easy choice if you are coming straight from your flight or staying north of the river.
- SRT is a separate operator leaving from Suseo (Gangnam side). Handy if you stay in south-east Seoul. SRT is usually a little cheaper, but the Korail Pass is not valid on SRT.
Both arrive at Busan Station.
3. How to book as a visitor
- Korail's official English site (letskorail.com) or the Korail Talk app. Have your passport name ready.
- A booking site that sells KTX tickets and the Korail Pass in English, if you prefer to pay in your own currency.
- Book a few days ahead for Friday evenings, Sunday afternoons and holidays. Seollal (Lunar New Year) and Chuseok are the busiest travel periods of the year.
4. Is the Korail Pass worth it?
The Korail Pass is for foreign visitors only: unlimited KTX and other Korail trains on the days you choose, with up to two seat reservations per day. The 2-day select pass is ₩131,000 for an adult.
| Your plan | Single tickets | Pass? |
|---|---|---|
| Seoul → Busan → Seoul | ₩119,600 | No: tickets are cheaper |
| Several long rides squeezed into two days (for example Seoul → Busan, then on to another city the next day and back to Seoul) | can pass ₩131,000 | Maybe: add up your exact fares first |
For a simple Seoul + Busan trip, single tickets win. The pass doesn't cover SRT or the city metro.
5. When you arrive at Busan Station
- Metro Line 1 runs from Busan Station to Nampo and Jagalchi in a few stops, and to Seomyeon the other way.
- For Haeundae, change at Seomyeon to Line 2. Allow about an hour with bags.
- Arriving before check-in? Leave your suitcase near the station and start sightseeing.
