Seoul and Busan are by far the two largest cities in Korea so it’s no surprise they have the fastest train in the country, the KTX, connecting them.
The KTX train is one of the quickest ways to travel between Seoul, Busan and over 12 other cities in Korea. Spread across 4 different train lines, the KTX connects the largest metropolitan areas with ease using these world-famous bullet trains.
Although this is not the only way to travel between these two major cities, it is one of the most popular. It’s preferred over flying as you don’t need as much time before boarding the train as you would need to spend at the airport.
Not to mention it’s significantly quicker to take a KTX train than taking the bus, regular commuter trains or driving between Busan and Seoul.

Seoul to Busan on KTX: Tickets
The KTX trains that travel from Seoul and Busan are the fastest in the country and can reach 330kph maximum speed.
Ticket Cost:
The fare for each journey varies depending on the time of day and the class you choose. For example, a first-class ticket will be significantly more expensive than a standard ticket since it’s the comfort you are paying for.
Sometimes the time of day can affect the KTX train ticket cost. Other times the price is affected by how far in advance or last minute you purchase. And just because you saw a price for one day, does not mean that price will still be there next time you return to the site. The prices fluctuate – much like airline tickets.
It is usually advisable to try and book your tickets as far in advance as you can to avoid disappointment.
Prices typically start at 85,000 KRW (£50) and go up to 110,000 KRW for last-minute tickets (£66)
How to purchase tickets:
There are a number of ways to buy tickets for your KTX train journey from Busan to Seoul or vice versa. You can buy online or in person and often even have the option to buy a reusable pass for multiple trips.

If you buy your tickets online it’s worth printing out your ticket and taking it with you as a paper copy. Although not always enforced, it’s safer to have a paper ticket rather than just relying on electronic ones. Though this completely depends on the staff at the station on the day.

KTX Train from Seoul to Busan: Ticket Classes
When travelling between Seoul and Busan, there are two types of classes available to sit in when taking the KTX train. First-class & Standard class.
In First-Class you’ll find the trains have 3 seats in each row. This creates a total of 127 seats in this class. They are relatively spacious compared to the other classes and you’ll have much more space overall.
Standard Class is a little less spacious with regard to seating. They have 4 seats in each row comprising 808 seats instead.
Luckily the journey on the KTX train does not take very long between Busan and Seoul, so even the standard class is deemed more comfortable than taking an economy flight. You certainly have a lot more personal space involved.

What to expect on the KTX train from Seoul to Busan
The KTX trains between Busan and Seoul travel at an average speed of 190 mph (305 kph).
At the KTX station, you simply get your tickets (either online in advance or at the station booth) and then head over to the appropriate platform to catch your train. You do not need to be there much ahead of time. Just make sure to be there before the train departs.
Unlike airports, you don’t need to be at the KTX train station far in advance so you have a much shorter time in the train station. This is one of the main reasons why so many people prefer taking the train over the faster method – flying. Taking a flight is only 55 minutes but when you factor in the security and check-in lines it can take a significantly longer amount of time.
Once you find the correct train carriage that corresponds with your ticket you can board the train and find your seat.
Each seat comes with a tray table and an outlet so you can charge your devices if necessary. You’ll find bathrooms throughout the train as well as vending machines to purchase some snacks – it is best to have cash as many of these machines do not accept cards.
You’ll find some nice views along the journey, however, the trains travel at such a fast speed it could be tricky to get good photographs of the scenery. If you are aiming to get photos specifically then it may be worthwhile taking one of the slower trains instead of the KTX between Busan and Seoul.
