• Modern, clean, and efficient: think of it as Korea’s answer to Japan’s Shinkansen or France’s TGV.

  • No airport security hassle.
  • Direct city-center to city-center (Seoul Station ↔ Busan Station).
  • Stable Wi-Fi, phone charging, restrooms, and snack carts.

Honest Caveats & What to Watch Out For

• Peak periods: Major Korean holidays (Chuseok, Lunar New Year) = sold-out trains. Book at least 2 weeks ahead.
• Last-minute tickets: Same-day seats are possible but not guaranteed. ClassKim can check real-time and suggest alternatives if needed.
• Luggage: No checked baggage—carry everything yourself. Station lockers are first-come, first-served.
• Snack cart: Sometimes limited selection; bring your own food if you have dietary restrictions.
• Refunds: Outright cancellations may incur a small fee. ClassKim can clarify refund policy at booking.
• Language: Most staff understand basic English, but detailed help (missed train, seat change) is smoother with a ClassKim interpreter.

Realistic Expectations: What’s It Really Like?

• Comfort: Seats are wider than economy class on planes; plenty of legroom.
• Punctuality: Trains leave on time—don’t be late!
• Crowds: Mornings and late afternoons are busiest. Midday = quieter.
• Solo & group friendly: Easy for solo travelers and families (group seats available).
