South Korea Trains: Fast Tracks and Slow Journeys

South Korea’s train network is known as one of the most efficient in the world. Clean, punctual, and well-connected, it offers several types of trains designed to suit different travel needs, from high-speed journeys between major cities to slower, budget-friendly routes through the countryside. Understanding the differences between these trains can help travelers choose the option that best matches their priorities.
Broadly speaking, Korea’s trains can be divided into three main categories: high-speed trains, intercity trains, and regional trains. Each type serves a different purpose within the network, varying in speed, price, comfort, and coverage. High-speed trains connect major cities in the shortest time possible, intercity trains offer a balance between cost and convenience, while regional trains focus on accessibility, reaching smaller towns and less-traveled areas.
High-speed trains: KTX and SRT
At the top of Korea’s rail system are the high-speed trains: KTX (Korea Train Express) and SRT (Super Rapid Train). These trains are designed for fast, long-distance travel, connecting key cities such as Seoul, Busan, and Gangneung.
Reaching speeds of up to 300 km/h, KTX can take passengers from Seoul to Busan in about 2h50, half the time of slower trains. SRT offers similar speeds and onboard comfort but departs from a different station and can be slightly cheaper.
In terms of comfort, both services provide spacious seating, quiet cabins, and amenities such as power outlets and luggage storage space, being the most convenient option for long-distance travel.
In terms of pricing, a one-way ticket from Seoul to Busan usually costs between 50,000 and 60,000 KRW (around €35-45), depending on the class and time of booking. First-class tickets are more expensive, but offer extra space and a quieter environment.
Tickets can be purchased through the official platforms such as KORAIL, via the KORAILTalk app, or the SR Corporation website and app. They are also available at ticket counters and vending machines in stations, all of which offer English-language options.
For tourists, the KORAIL Pass can be a convenient option, allowing unlimited travel on KTX and other trains for a fixed number of days. Discounts are sometimes available for groups, children, and early bookings.
Recommended for: travelers who prioritize speed, efficiency, and convenience.
Intercity trains: ITX
The ITX (Intercity Train Express) category offers a middle ground between high-speed and regional trains. With speeds of around 150-180 km/h, ITX trains are slower than KTX but still efficient for medium-distance travel.
There are several types, including ITX-Saemaeul, ITX-Cheongchun, and the newer ITX-Maum. These trains typically connect cities and suburban areas, making them popular for both commuters and travelers exploring destinations closer to Seoul.
Comfort levels remain high, with wide seats and large windows that make the journey more scenic and relaxed. Travel times are longer compared to high-speed trains - for example, a Seoul–Busan trip can take around 4 hours.
In terms of pricing, ITX trains are noticeably more affordable. A short route such as Seoul to Chuncheon typically costs between 7,000 and 10,000 KRW (€4-6), while longer journeys can cost between 20,000 and 40,000 KRW (€12-23), still significantly cheaper than KTX.
Tickets can be booked through the same channels, including the KORAIL website and app, or directly at train stations. Seat reservations are generally included in the ticket price, making the process straightforward. Although the KORAIL Pass also covers ITX trains, it is usually more beneficial for long-distance travel, as ITX tickets are already relatively inexpensive.
Recommended for: travelers seeking a balance between affordability and comfort.
Regional trains: Mugunghwa
At the most affordable end are the Mugunghwa trains, which serve local routes and stop frequently along the way. They connect smaller towns and rural areas that are not covered by high-speed services, making them essential for domestic travel beyond major cities.
In terms of pricing, they are the cheapest option available. A long-distance trip such as Seoul to Busan can cost around 25,000-30,000 KRW (€18-22), making them a budget-friendly alternative for travelers who are not in a hurry.
Tickets can be purchased through KORAIL platforms, via its website and mobile app, or directly at train stations. Seat reservations are optional on some routes, and unreserved seating is sometimes available, offering more flexibility but potentially leading to crowded conditions during peak hours.
Although the trains are more basic and slower, they offer a different kind of experience: a quieter, more local perspective of Korea, passing through smaller stations and scenic landscapes.
Recommended for: budget-conscious travelers, those interested in exploring more than major cities.
Other rail services
Beyond the main train categories, Korea also offers several specialized rail services designed for specific travel needs.
One of the most commonly used is the AREX (Airport Railroad Express), which connects Incheon International Airport to Seoul. It operates in two versions: an Express Train, which runs non-stop in around 40-45 minutes, and an All-stop Train, which is cheaper but makes multiple stops along the way. Ticket prices typically range from 4,000 to 9,500 KRW (€2-6), depending on the service.
In addition to functional transport, Korea also features a number of tourist scenic trains, designed to highlight the country’s natural landscapes rather than speed. Services such as the V-Train (Valley Train) and O-Train (Circular Train) travel through rural regions, offering panoramic views and a slower, more immersive experience.
While these trains are not intended for everyday commuting, they provide a unique way to explore a different side of Korea, combining travel with sightseeing.
Practical tips for traveling by train in Korea
For first-time visitors, Korea’s railway system is easy to navigate, but a few practical tips can make the experience even smoother:
Tickets for high-speed trains often sell out quickly, especially on weekends and holidays, so booking in advance is recommended. Platforms such as KORAILTalk or the KORAIL website allow users to check schedules and reserve seats easily.
Food and drinks are allowed on trains, and many travelers bring snacks or buy them from convenience stores located inside stations.
