Tourist Guide to Using KTX Trains

Buying a KTX ticket is simple, with multiple options for both locals and foreigners. You can purchase tickets at any major train station in Korea, where English-friendly kiosks and ticket counters are available. Alternatively, online booking is fast and convenient via the official Korail website or mobile app. You can also book through third-party sites like Klook, which sometimes offer discounts for tourists.
Tickets can be reserved weeks in advance, and seat selections are usually available at no extra charge. First Class and Economy options are offered, with different price points and amenities. Payment can be made using Korean credit cards or international cards depending on the platform.

During holidays or weekends, trains fill up quickly, so it's best to book early. While booking, you may notice another high-speed train option: the SRT (Super Rapid Train). Operated by a different company, SRT tickets must be bought separately and usually depart from Suseo Station in Seoul, not Seoul Station. If you're comparing KTX vs SRT, both are similar in speed and comfort, but the departure and arrival stations may affect your choice. For a full Korea train comparison, consider travel time, convenience, and connectivity to your destination. If you’re wondering how to use KTX trains, it’s important to understand ticketing, check-in procedures, and departure points for both the KTX and SRT to make an informed decision.

Once onboard, you'll notice the clean and modern interior of the KTX. Seats in Economy Class are comfortable and include tray tables, charging ports, and Wi-Fi in many cases. First Class offers larger seats, more legroom, and complimentary snacks or beverages. Bathrooms are clean and available in multiple cars, and some trains also include vending machines or water dispensers.
The ride is smooth and often very quiet. Most passengers use the time to nap, read, or work, so noise should be kept to a minimum. If you're traveling with children, try to keep them entertained quietly. If you're wondering how to use KTX trains, it's important to note that once aboard, the experience is designed for comfort and tranquility.

Food isn’t served unless you're in First Class, but you're welcome to bring your own snacks or drinks. Keep your area tidy, and dispose of trash in the bins located at the end of each car. For large luggage, use the storage areas rather than blocking aisles or seats. This is particularly important during busy travel times.
KTX offers a fast and scenic ride across the country. If you're conducting a Korea train comparison, the KTX is slightly more expensive than the SRT, but it's also better connected to downtown Seoul and other major stations. Depending on your priorities—price, location, or timing—both are solid choices.

When your train approaches your stop, announcements will be made in Korean and English. Make sure to gather your belongings a few minutes before arrival. Doors open for only a short time, so move quickly but safely to exit. Some stations are large and may require walking or navigating stairs and escalators, especially if you're transferring.
Follow the signs for "Exit" or "Transfer", depending on your next destination. If you're continuing your journey by subway, most KTX stations are connected to local metro systems. For example, Busan Station links directly to Busan Metro Line 1, while Seoul Station connects to Line 1 and Line 4. Taxis, buses, and rental car services are also readily available outside most stations.

Luggage trolleys can be found near platforms, and staff are usually around to assist if needed. If you've traveled a long distance, take a moment to regroup at the station’s rest areas or cafés before continuing. Many KTX stations are also shopping and dining hubs, so you might want to explore a bit.
If you're planning on catching another train, make sure to check your connection details in advance. Transfers between KTX and SRT aren't always seamless since they use different operators and stations. Keep this in mind if you’re doing a Korea train comparison that involves multiple legs of travel.

To ensure a pleasant experience for yourself and others, it’s good to understand Korean train etiquette. As mentioned earlier, quiet is expected on board—use headphones and avoid loud conversations. Eating is allowed, but avoid strong-smelling foods like kimchi or instant noodles.
Keep the aisles clear of bags and personal items. If traveling with children or groups, be mindful of noise and movement within the train. Clean up your area before leaving the train, and don’t leave behind trash or personal belongings. If you’re unsure where to sit, just ask a conductor or check the digital displays above each seat.

You’re not allowed to switch cars during the ride unless you're visiting the bathroom or going to the vending machine area. Taking photos is fine, but avoid blocking walkways or disturbing other passengers. Smoking is strictly prohibited anywhere on the train or platform.
If you're comparing KTX vs SRT, keep in mind that both follow similar etiquette and policies, but departure stations and amenities may vary slightly. KTX tends to be more central for tourists, while SRT may be more convenient for travelers based in southern Seoul.
