🚄 How to Use KTX Trains in Korea (Complete First-Timer Guide)

Korea’s KTX (Korea Train Express) is the country’s high-speed rail network. It connects major cities like Seoul–Busan, Seoul–Gwangju/Mokpo, Seoul–Daegu, and Seoul–Gangneung quickly and comfortably. If you want to save time versus buses and avoid airport-style hassle, KTX is often the best choice.

🗺️ 1) What KTX Lines Cover

• Gyeongbu KTX: Seoul ↔ Busan (via Daejeon, Daegu, etc.)
• Honam KTX: Seoul/Yongsan ↔ GwangjuSongjeong/Mokpo (normally Yongsan)
• Jeolla KTX: Yongsan ↔ Yeosu-Expo (via Iksan)
• Gangneung KTX: Seoul/Cheongnyangni ↔ Gangneung (East coast)
• Gyeongjeon KTX: Seoul ↔ Jinju/Masan (via Miryang/Jinyeong)

Typical end-to-end travel times: Seoul–Busan ~2h 15m (fastest services) and around ~60–90m for Seoul–Gangneung, depending on the train and stops.

⚡ 2) How Fast Is KTX?

KTX operates at up to ~300–305 km/h on high-speed sections. In practice, journey times depend on routing and intermediate stops.

🏷️ 3) Ticket Types & How to Buy

• Classes: First Class (wider 2+1 seating, quieter) and Standard Class (2+2 seating).
• Seat types: Reserved (assigned seat), sometimes Standing (peak periods). Family/compartment seats exist on select services.
• Where to buy:
  • Official Korail website (Let’s Korail) for foreigners
  • Korail app (mobile e-ticket with QR)
  • Station ticket counters & kiosks (English available)
• Booking window: Typically up to 1 month in advance for most services.

🎫 4) KORAIL PASS (Korea Rail Pass)

If you’ll take multiple intercity trips in a few days, consider the KORAIL PASS (for short-term visitors). It allows unlimited rides on designated days (Flexible or Consecutive options). Great value for itineraries like Seoul → Busan → Gyeongju → Seoul within a week.

• Buy online before traveling or after arrival (passport required).
• Choose Flexible (e.g., any 2 or 3 days within a set period) or Consecutive (e.g., 3/5 days in a row).
• Seat reservations are still required for each train you plan to ride.

🧭 5) Major Stations & Where to Depart in Seoul

• Seoul Station: Main hub for Gyeongbu KTX (Busan/Daegu/Daejeon).
• Yongsan Station: Honam/Jeolla KTX (Gwangju/Mokpo/Yeosu).
• Cheongnyangni Station: Gangneung KTX (East coast).

Tip: Check your departure station printed on the ticket; not all KTX lines depart from Seoul Station.

🧳 6) Luggage & Onboard Experience

• Luggage: Overhead racks for carry-ons; larger bags can be placed behind the last row or at car ends (keep aisles clear).
• Facilities: Restrooms in multiple cars; power outlets are common on newer rolling stock and First Class.
• Food & drink: No dining car; bring snacks/drinks (trash bins at car ends).

🔁 7) KTX vs SRT — What’s the Difference?

SRT (Super Rapid Train) is a separate high-speed service operated by SR Corporation, departing from Suseo Station (southeast Seoul) to Busan and Mokpo via the same HSR corridors. SRT can be a few minutes faster on some routes if Suseo is closer to you. Tickets are sold on the SR (SRT) system separately from Korail.

📱 8) Step-by-Step: Buying a Ticket Online

1. Go to the Korail official site (global English) or open the Korail app.
2. Select route (e.g., Seoul → Busan), date, and time.
3. Choose class (First/Standard) and seat preference.
4. Pay with an international card; receive your QR e-ticket.
5. At the station, go straight to the platform and scan the QR at the gate (or show to staff).

⏱️ 9) Typical Travel Times (Examples)

• Seoul ↔ Busan: ~2h 15m (fastest) to ~2h 40m depending on stops.
• Seoul/Yongsan ↔ GwangjuSongjeong: ~1h 30m–2h.
• Seoul/Cheongnyangni ↔ Gangneung: ~1h 50m (varies by service).

Times vary with train patterns (express vs all-stop). Always check your specific train’s schedule.

🧾 10) Changes, Refunds & Missed Trains

• Change/Refund rules exist with cut-off times and small fees depending on when you modify.
• If you miss your reserved train, ticket rules apply; visit the ticket desk promptly for options.

🛑 11) Common Mistakes to Avoid

• Going to the wrong station (e.g., Yongsan vs Seoul Station).
• Assuming all trains have the same stops — check intermediate stations before booking.
• Forgetting to reserve seats when using a Korail Pass (reservation still required).
• Bringing oversized luggage that blocks aisles — store at car ends instead.

🌟 12) Pro Tips (Travel Like a Local)

• Pick your station based on where you stay (e.g., Yongsan for Honam/Jeolla, Suseo for SRT).
• Off-peak trains (mid-day or late evening) are usually cheaper/easier to book.
• For cherry blossoms or holidays, book as soon as the 1-month window opens.
• Combine KTX with local passes (e.g., city transit cards) to simplify transfers at arrival stations.

✅ In Summary

• KTX is fast (≈300 km/h), frequent, and connects most major cities.
• Buy via the Korail official site/app or at station kiosks.
• Korail Pass can save money if you’re riding multiple intercity trips.
• Double-check your departure station, seat class, and stops before you go.
