Book KTX tickets through the official KORAIL website or KORAIL+ app, then check the exact departure station before paying. Seoul Station, Yongsan, Cheongnyangni and Suseo are different places, even when trains head toward the same city. Choose your train and seat, complete payment, and save the actual ticket—not just a search result or card-charge alert. Check the station and departure time again before leaving your accommodation.
There is also an important 2026 update: KTX and the former SRT network entered integrated operation on September 1, 2026. Old videos that tell you to search two completely separate systems can now be misleading. This article reflects the new system and shows the practical choices that still matter.

1. The Quick Answer
| Your situation | Best action |
|---|---|
| First-time visitor booking from abroad | Use the official multilingual KORAIL website |
| You want every high-speed option from Seoul and Suseo | Use the updated KORAIL+ app or KORAIL website |
| Your trip is during a weekend, festival or holiday | Book as soon as sales open |
| Your foreign card fails online | Try another supported card or buy at a staffed station counter |
| You will take many long-distance trains | Compare individual fares with a KORAIL Pass before paying |
| You have a T-money or EZL card | Keep it for local transit; it does not replace a reserved KTX ticket |
The official booking address is KORAIL’s multilingual website. Bookmark it instead of trusting the first sponsored result. Third-party platforms can be legitimate, but the official site gives you the clearest path to schedules, seat selection and ticket management without an unnecessary reseller layer.
2. What Changed on September 1, 2026
For years, travelers learned one rule: KTX usually meant Seoul Station and KORAIL, while SRT meant Suseo Station and a separate app. That division changed in September 2026.
- KORAIL launched the integrated KORAIL+ app in August 2026.
- From September 1, KTX and the former SRT system began integrated operation.
- High-speed trains departing from Seoul and Suseo can be searched and booked through KORAIL+ and the KORAIL website.
- The former SRT trains are being operated under the KTX system, with SRT renamed KTX-Sancheon in KORAIL’s official announcement.
- KORAIL announced an average 10% reduction in KTX fares. Its example fare for Seoul–Busan changed from ₩59,800 to ₩54,400.
Read KORAIL’s official high-speed rail integration notice for the transition details. The practical benefit for a visitor is simple: search Seoul, Yongsan and Suseo options in the same official system before deciding which station is best for your hotel.
Some older apps may remain available temporarily during the transition. Use the new KORAIL+ app or the official website as your default, and check the train date rather than relying on an old tutorial.
3. What to Prepare Before Booking
- Passport name: enter the passenger information consistently and carry the passport used for the booking.
- Exact stations: know whether you need Seoul, Yongsan, Cheongnyangni or Suseo—not just “Seoul.”
- Travel date and time window: search a range when possible instead of one perfect departure.
- Payment card: keep a second international card available in case the first issuer blocks the transaction.
- Email and screenshot storage: save the booking confirmation and ticket where you can open them without relying on station Wi-Fi.
You do not need a Korean transit card to buy a KTX ticket. T-money and EZL are useful for subways and buses before and after the train, but the intercity seat is a separate reservation. Our transportation card comparison explains where each card fits.
4. How to Book KTX Tickets in Korea Step by Step
Step 1: Open the official system
Use KORAIL’s multilingual website or the official KORAIL+ app. On the website, select your language before starting. Avoid entering passport or payment information on a look-alike page.
Step 2: Enter the exact stations
Choose the departure station, arrival station, date and number of passengers. For Busan, the destination is Busan Station. For central Gyeongju, the high-speed stop is Gyeongju Station (경주역, formerly Singyeongju), followed by a local bus or taxi. City names and station names are not always identical.
Step 3: Compare trains, not only departure times
Check the departure station, arrival time, travel duration and whether the trip is direct. A slightly later direct train can be easier than an earlier itinerary with a transfer, especially with luggage.
Step 4: Select a seat
The online system can offer a seat map. Choose standard or first class, then check the car and seat number before payment. If motion direction matters to you, look for forward-facing orientation where the interface provides it; some Korean trains have seats facing both directions.
Step 5: Pay and save the ticket
Complete payment, then save the mobile ticket and confirmation number. Take a screenshot as a backup, but keep the live ticket or original confirmation available because staff may need the full booking details. Do not assume that a card authorization message alone means the reservation succeeded.
5. Choose the Correct Seoul Departure Station
| Station | Usually useful for | Traveler warning |
|---|---|---|
| Seoul Station | Busan, Daejeon, Daegu, Gyeongju and many major routes | Large and busy; allow time to find the KTX concourse |
| Yongsan Station | Honam and Jeolla routes, including Gwangju and Mokpo | Do not automatically go to Seoul Station |
| Cheongnyangni Station | Gangwon, Andong and some eastern routes | It is east of central Seoul and may be far from your hotel |
| Suseo Station | High-speed routes convenient for Gangnam and southeast Seoul | Suseo is not Seoul Station; check your navigation time |
The cheapest-looking ticket can become the most stressful if the station is an hour from your accommodation. Check the complete door-to-platform route in Naver Map or KakaoMap before paying. See our essential Korea travel apps guide for navigation setup.
6. Seats, Direction and Luggage
Standard class is comfortable for most travelers and includes an assigned seat. First class offers more space, but it is not necessary for a two- or three-hour journey unless you value the quieter cabin and extra room.
- Match the car number and seat number on your ticket before boarding.
- Large luggage areas are limited and vary by train type. Board calmly but do not arrive at the final minute if you carry a large suitcase.
- Smaller bags can use overhead racks when their size and weight are safe.
- Keep passports, wallets, medicine and electronics with you rather than inside a suitcase left near the door.
- Do not block aisles, vestibules or emergency equipment with luggage.
Korea Tourism Organization notes that high-speed trains include restrooms and other onboard facilities, and most trains provide Wi-Fi, although the connection can be unstable. Download maps and hotel information before departure instead of making the trip depend on onboard internet.
7. When Tickets Open—and When They Sell Out
The official visitor guidance says tickets usually go on sale at 07:00 one month before departure. Website sales generally continue until 20 minutes before departure, while app sales can remain available closer to departure. Treat those times as a last-resort limit, not a travel strategy.
- Book early: Friday evenings, Sunday afternoons, festival weekends and popular coastal routes.
- Book very early: Korean national holidays such as Seollal and Chuseok, when separate reservation windows and rules may apply.
- Search flexible times: early morning or later evening trains may remain when midday trains are full.
- Check nearby stations: Seoul versus Suseo can create additional options after the 2026 integration.
If a train is sold out, refresh occasionally because canceled seats can return. Never buy a screenshot or ticket from an unknown individual. A ticket tied to someone else’s details can create a much larger problem than waiting for another departure.
8. Changes, Cancellations and Missed Trains
Do not simply abandon a ticket when your plan changes. Open the same official channel used for purchase and review the return or change option before departure. Fees depend on timing, travel date and ticket conditions.
KORAIL’s September 2026 integration notice says high-speed tickets can be changed without a fee within the permitted change window—up to seven days before or after the travel date and no later than 30 minutes before departure—under the new integrated service. It also extends a limited fee-free refund benefit for tickets refunded within ten minutes of payment, provided the train is still at least 30 minutes away and the daily limit is not exceeded. Always read the rule displayed for your specific ticket before confirming.
Once the departure time has passed, online options and refund amounts can change. If you miss the train, go directly to a staffed ticket counter instead of boarding another train with the old ticket. English help is available through the KORAIL Customer Center at +82-1599-7777 from 08:00 to 20:00, according to the current visitor guide.
9. Is a KORAIL Pass Worth It?
A KORAIL Pass is designed for international travelers taking multiple train journeys. It can work well when several expensive intercity trips are packed into a short period, but it is not automatically cheaper for a simple Seoul–Busan return trip.
- List every planned train journey and its point-to-point fare.
- Compare that total with the pass price for your travel days.
- Check whether your exact train and route are covered under the current rules.
- Remember that a pass still requires seat reservations when you want an assigned seat.
- Carry the passport connected to the pass.
Because the high-speed network changed in September 2026, verify coverage on the official KORAIL Pass page before purchase. Do not rely on an older article that describes SRT and KTX as permanently separate products.
10. What to Do on Travel Day
- Confirm the station name, departure time, train number, car and seat.
- Navigate to the intercity rail station—not a subway station with a similar name.
- Arrive about 20–30 minutes early on a normal day; allow more time with luggage or during holidays.
- Check the electronic departure board for the platform.
- Stand near the floor marker for your car number when possible.
- Board the correct train, store luggage safely and sit in the assigned seat.
- Keep your ticket available even if there is no gate scan at the entrance.
Korean intercity trains often use onboard inspection rather than an airport-style boarding gate. That does not mean the ride is unreserved. The conductor’s system shows which seats should be occupied.
11. Easy KTX Routes for Your Korea Trip
- Seoul to Busan: start with our Busan local food itinerary for markets, pork soup and coastal nights.
- Seoul to Gyeongju Station: continue with the Gyeongju travel guide for Silla history, night views and local food.
- Seoul to Dongdaegu: use the Daegu travel guide for Seomun Market, alley walks and Apsan after dark.
- Cheongnyangni to Andong: read the Andong guide for Hahoe Village, jjimdak and Woryeonggyo.
- Seoul to Busan, then onward: connect by bus for our Geoje and Tongyeong itinerary.
For the local subway or bus at either end, read our South Korea public transportation guide. Long-distance rail and local transit are separate systems, but together they make a regional trip much easier than renting a car for a first visit.
12. Common Mistakes and Final Checklist
- Wrong station: Seoul, Yongsan, Cheongnyangni and Suseo are different places.
- Wrong date: check whether a late-night departure crosses midnight.
- Old app advice: use KORAIL+ or the official website for the post–September 2026 system.
- Card charged, no ticket: confirm that an actual ticket appears before leaving the page.
- T-money confusion: a local transit card does not reserve a KTX seat.
- No offline copy: save the ticket before entering a station with weak reception.
- Too much luggage: pack so you can move and store your own bags safely.
- Unofficial resale: never buy a personal screenshot or secondhand ticket.
Before leaving for the station, open the saved ticket and read the departure station, date, time and train number together. If you compared different stations or services during booking, check which one you actually paid for. Then allow time to find the platform with your luggage.
Last reviewed: September 2, 2026. Train names, schedules, fares, sales windows and refund rules can change. Confirm the final details shown by KORAIL for your exact departure.
