What should I know before I ride?
Route and booking details checked October 26, 2026
The KTX between Seoul and Busan runs on the Gyeongbu Line, a 447.1 km route, and is the fastest rail link between Korea's two largest cities. According to the VisitKorea train page, KTX reaches up to 330 km/h and departs from Seoul, Yongsan and Cheongnyangni stations. Korail's own passenger transport page says KTX service began on April 1, 2004, and that the second phase of the Gyeongbu high-speed line opened on November 1, 2010.
- Worth knowing: VisitKorea lists restrooms, nursing rooms and vending machines on board, plus free Wi-Fi that may be unstable. Do not plan to rely on it for video calls.
- A common mistake: Booking a train without checking the departure station. Seoul Station, Yongsan and the separate SRT terminal at Suseo are different places, so match your ticket to your hotel location.
- Local tip: Reserve early. The Korea Times reports that Korail has sold tickets up to two months ahead since October 1, 2026, and the step-by-step process is in our KTX booking guide.
Which stations should I use in Seoul and Busan?
Most visitors will leave from Seoul Station and arrive at Busan Station, which are the main KTX hubs at each end. A Seoul to Busan travel guide describes Seoul Station as connected to Metro Lines 1 and 4 and the AREX airport rail link, with Yongsan Station two stops south on Line 1 and serving some KTX trains.
- Seoul Station: The usual starting point. From Incheon Airport, the guide says to take AREX to Seoul Station and change there; see the Incheon Airport to Seoul guide.
- Yongsan and Cheongnyangni: VisitKorea names both as KTX departure stations. Use them only if your chosen train starts there.
- Busan Station: The main KTX terminus in Dong-gu, connected to Busan Metro Line 1, according to the same guide.
- SRT is separate: The same guide says SRT trains use Suseo Station in Gangnam and are a different service from KTX. VisitKorea notes that the Korail Pass excludes SRT.
How long does the KTX take, and which train should I pick?
The quickest KTX trains take about 2 hours 15 minutes, while trains that stop at more stations take up to around 3 hours. Travel guides give slightly different figures, with the travel guide above citing about 2 hours 17 minutes for the fastest nonstop trains and 2 hours 40 minutes to 3 hours 25 minutes for trains with intermediate stops. Compare the arrival times on the booking screen, because the journey length depends on the train.
- Fewer stops, faster trip: Choose a train with few or no intermediate stops if time matters more than departure hour.
- KTX-Cheongryong: Stars and Stripes reported in May 2024 that this newer train runs Seoul to Busan in about 2 hours 10 minutes and stops only at a few stations, including Daejeon. It was then running six trips a week, so check whether it appears for your date. The article is from 2024 and the schedule may have changed.
- Frequency: A booking listing cited by a travel guide mentions more than 100 daily departures, but I could not verify that on an official page. Open the Korail timetable for your date.
- Customer line: VisitKorea lists an English-only Korail customer center at +82-1599-7777, daily 08:00 to 20:00.
How much does the ticket cost?
A one-way standard seat from Seoul to Busan costs roughly 55,000 to 60,000 won, and first class costs more. I could not confirm the current fare table on an official page this run, so treat the numbers below as approximate and check the price on the Korail booking screen before you pay.
| Item | Approximate figure | Source and note |
|---|---|---|
| Standard class, one way | About 59,800 won | Travel guide; prices vary by day and train |
| First class, one way | About 83,700 won on some services | Same guide; confirm at booking |
| Fastest journey | About 2 h 15 min to 2 h 17 min | Travel guides |
| Slowest KTX journey | Up to about 3 h 25 min | Trains with more stops |
| Korail Pass | 2-, 3-, 4- or 5-day passes within ten days | VisitKorea; first class costs 50% of the fare |
Practical example: a visitor planning Seoul to Busan and back should price two single tickets first, then compare that total with a pass using our Korail Pass guide. The pass lets holders reserve up to two seats a day, per VisitKorea.
How much luggage can I bring?
Korail's published rule, as quoted by a travel guide, is that you must be able to carry your own belongings, with no more than two pieces, and bags must not block seats or aisles. The KTX luggage and seat guide found no suitcase size or weight limit on the Korail page it cites and advises against applying airline measurements. Storage space varies by train and carriage, so check Korail before travelling with several large bags.
- Travel light: The KoreaToDo guide suggests dropping heavy bags at your Seoul accommodation first if you only visit Busan for a short time.
- Lost something: The luggage guide says to tell the train attendant if you notice on the train, or the station office right after you get off, and to have your train, carriage and seat number ready.
- Unverified on an official page: The two-piece rule comes from a secondary source, so confirm it with Korail on +82-1599-7777.
What should I do when I arrive in Busan?
Walk to the Busan Metro Line 1 platforms at Busan Station, or use a taxi, and check your destination area first. Busan Station sits on Line 1, which a travel guide links to downtown. The Line 1 stops near Nampo and Jagalchi are covered in our Busan metro guide.
- Pick your base: Compare Haeundae, Seomyeon and Nampo in our first time in Busan guide before you book a hotel.
- Plan the days: Our Busan 3-day itinerary lists routes, and the 5 days in Korea guide shows how to fit the KTX day into a Seoul and Busan trip.
- Return trip: Book your train back in the same session, because popular evening trains can sell out.
