KTX guide
KTX Luggage Rules
Unlike airlines, KTX does not usually enforce strict baggage weighing at boarding. However, space onboard is limited. This page explains what you can realistically bring, where to store it, and how to avoid problems during busy travel periods.

Basic rule (what’s actually allowed)
KTX does not operate like an airline. There is no typical check-in counter weighing your bag. You are generally allowed to bring luggage that you can reasonably carry and store safely.
If you can carry it yourself and it fits in overhead racks or end-of-car storage, it is usually acceptable.
Where to store luggage on KTX
- Overhead racks: Suitable for backpacks and medium-sized suitcases.
- Behind last row seats: Some cars have limited extra space.
- End-of-car storage: Best place for large suitcases.
If you’re unsure about seat layout, see: /ktx/seat-classes.
Large / oversized suitcases
Very large suitcases (for example, large checked airline bags) can fit in end-of-car storage, but space is limited.
During weekends, holidays, and peak travel times (e.g., Seoul ↔ Busan), luggage areas can fill up quickly.
Example high-demand route: Seoul → Busan.
What happens when trains are busy?
If storage space fills up, passengers may need to keep smaller bags near their seats. Extremely large items may cause inconvenience to others.
Arrive early, board promptly, and secure end-of-car storage if you have a large suitcase.
Practical tips for travelers
- Choose aisle seats if you need easier access to luggage.
- Keep valuables in a small personal bag near you.
