The KTX (Korea Train Express) is South Korea’s pride when it comes to fast, modern rail travel. This high-speed train is the go-to option for travelers looking to cut down on travel time while maximizing their itinerary.

Speeds regularly hit over 300 km/h, making it possible to go from Seoul to Busan in under 2.5 hours. KTX covers major intercity routes, including Seoul to Busan, Seoul to Mokpo, Seoul to Gwangju, and Seoul to Daejeon, with frequent departures throughout the day. Most trains leave from Seoul Station, which is easily accessible via subway or taxi. Onboard, the KTX feels like a modern airplane — only with more legroom.

There are reserved seats in Standard and First Class, power outlets in most cars, fold-down tray tables, clean restrooms, luggage storage areas, and occasional snack trolleys. First Class passengers enjoy wider seats and complimentary bottled water and snacks.The train is smooth, quiet, and punctual — ideal for business travelers, families, or anyone wanting to get the most out of their Korean adventure. Booking tickets is simple online, and seats can fill up fast on weekends, so plan ahead.

The SRT (Super Rapid Train) is a newer addition to Korea’s high-speed rail options and runs on many of the same tracks as the KTX. However, it departs from Suseo Station in southern Seoul, making it incredibly convenient for travelers staying in the Gangnam or Jamsil areas.

SRT connects Seoul to cities like Busan, Daegu, and Gwangju, offering similar travel times and competitive prices. While it’s just as fast as the KTX, the SRT is known for being quieter and slightly more spacious.

The interiors are minimalist and modern, with clean lighting, comfortable seating with charging ports, luggage racks, and dedicated quiet zones.

If you’re looking for high-speed efficiency with a slightly different departure point or a more relaxed ride, the SRT is a fantastic option. It's also known for its punctuality and smooth booking experience.

ITX (Intercity Train Express) trains are a solid choice for travelers who want comfort, decent speed, and a chance to enjoy the view. They’re a step down from the bullet trains in terms of speed, but they often take more scenic routes, making them perfect for day trips or regional travel.

One of the most popular versions, the ITX-Cheongchun, runs between Yongsan Station in Seoul and Chuncheon, a route beloved by travelers heading to Nami Island, Petite France, or the Gapyeong area. These trains are often double-decker, which means more seating and great views from the upper deck.
Inside, the trains offer spacious reserved seating, large windows, luggage areas, clean toilets, and sometimes even vending machines. ITX is more relaxed than the KTX or SRT, which makes it a great choice for couples, small groups, and independent travelers looking to take things slow.

Nuriro trains are one of Korea’s newest additions to its passenger rail services. Launched with sustainability and comfort in mind, Nuriro trains operate on mid-distance regional routes and offer an updated onboard experience compared to older trains like Mugunghwa.
Routes include popular commuter-friendly lines such as Seoul to Iksan and Seoul to Sinchang, with stops in growing urban and suburban areas. While they’re not high-speed trains, they’re reliable, clean, and perfect for regional day trips or traveling between mid-size cities.

The interiors are modern, with quiet, air-conditioned cabins, USB and power outlets, and comfortable reserved seating. They’re a great option for travelers looking for something newer than Mugunghwa but without the speed (or cost) of KTX.

Nuriro’s focus on comfort, affordability, and energy efficiency makes it a smart and sustainable choice for curious explorers and eco-minded travelers.

Named after South Korea’s national flower, the Mugunghwa-ho is the country’s oldest and most widely used passenger train service. Although it’s slower than the other options listed here, it serves an important role: reaching smaller towns and rural areas that high-speed lines bypass.

Mugunghwa trains cover a wide range of routes, including Seoul to Gangneung, Seoul to Yeosu, and Seoul to Pohang, and they often make more frequent stops than express trains. This makes them especially useful for travelers seeking off-the-beaten-path destinations, scenic countryside rides, or budget-friendly travel.

Inside, Mugunghwa trains are basic but comfortable. Seating can be reserved or unreserved, depending on the time and train. While amenities are limited compared to newer services, you’ll still find restrooms, snack carts, and decent legroom. For budget-conscious travelers or those who appreciate a slower pace, Mugunghwa trains offer a reliable and relaxed way to explore Korea.
