🚄 Seoul ↔ Busan: KTX vs SRT — Which Should You Choose?

Traveling between Seoul and Busan by high-speed rail is fast, comfortable, and hassle-free. Korea has two services on this corridor: KTX (by Korail) and SRT (by SR Corporation). Both are excellent — the better choice simply depends on where you depart from, your schedule, and seat availability.

🧭 Quick Overview

• KTX: Departs mainly from Seoul Station (city center). Also serves Yongsan for some lines.
• SRT: Departs from Suseo Station (southeast Seoul, Gangnam area).
• Travel time: Broadly similar; fastest runs are about ~2h 15m (nonstop/limited-stop patterns).
• Frequency: KTX tends to have more departures overall; SRT is frequent during peak times.
• Comfort: Both offer First (2+1) and Standard (2+2) classes; clean, air-conditioned, reserved seating.

🚉 Departure Stations & Access

• KTX → Seoul Station: Best if you stay near Myeongdong/City Hall/Hongdae.
  • Subway hub (Lines 1 & 4 + Airport Railroad at nearby Seoul Station/AREX).
  • Plenty of food courts, convenience stores, lockers.
• SRT → Suseo Station: Best if you’re based in Gangnam/Jamsil/Songpa.
  • Subway Lines 3, Suseo-Pangyo (Shinbundang), and Bundang Line connections.
  • Usually less crowded in concourses; quick access from south-east Seoul.

⏱️ Travel Time & Frequency

• Fastest timings: Roughly ~2h 15m on both KTX and SRT limited-stop services.
• Typical range: About 2h 20m–2h 40m, depending on the number of stops and timetable.
• Frequency: KTX generally offers more trains per day; SRT runs are dense at peak hours.

💺 Seats, Onboard & Luggage

• Classes: First (2+1, wider seats, quieter) / Standard (2+2, great value).
• Facilities: Clean restrooms, overhead racks, car-end luggage spaces; outlets more common in First/newer trains.
• Food: No dining car — bring snacks/drinks; trash bins at car ends.

🏷️ Fares & Tickets

• Price: Generally comparable between KTX and SRT; occasional promos may make one cheaper on specific dates.
• Booking:
  • KTX: Let’s Korail website/app, station counters & kiosks.
  • SRT: SR/SRT website/app, station counters & kiosks (Suseo, etc.).
• Reservations: Open roughly ~1 month in advance; holiday seasons sell out quickly.

🔁 Exchanges, Refunds & Peak Seasons

• Changes/Refunds: Allowed with conditions/fees that vary by timing — check rules during purchase.
• Peak periods: Cherry blossom, summer weekends, Chuseok/Seollal → reserve ASAP when sales open.
