South Korea’s high-speed rail system is one of the most advanced in the world, operating under the Korea Train Express (KTX) brand. Since its launch in 2004, the country has developed several types of high-speed trains. The original KTX-I was based on French TGV technology and marked the beginning of high-speed travel between major cities like Seoul and Busan. In 2010, the KTX-Sancheon, also known as KTX-II, became the first high-speed train fully developed in Korea by Hyundai Rotem. It introduced improved safety, design, and comfort features tailored to Korean needs. More recently, the KTX-Eum, launched in 2021, was introduced as a next-generation electric multiple unit (EMU) designed for semi-high-speed lines such as the Jungang Line. It operates at slightly lower speeds but offers greater efficiency and accessibility on less crowded routes. In 2024, Korea unveiled the KTX-Cheongryong, or “Blue Dragon,” an advanced EMU-type high-speed train capable of reaching 320 km/h, equipped with cutting-edge technology and a futuristic design. Alongside these, the SRT (Super Rapid Train), operated by SR Corporation since 2016, provides similar service using KTX-Sancheon-type rolling stock but departs from Suseo Station in Seoul, offering a private alternative to Korail-operated KTX.
The KTX-Sancheon (산천), meaning “mountain and stream,” symbolizes a Korean identity rooted in natural beauty. Built by Hyundai Rotem and introduced in 2010, this train runs at speeds up to 305 km/h and connects major routes such as the Gyeongbu and Honam lines. It is known for its aerodynamic design, enhanced safety systems, and passenger-friendly interiors. The Sancheon represents a major milestone in Korean rail technology, marking the country’s move from foreign dependence to domestic innovation in high-speed rail transport. Today, it remains one of the most commonly seen KTX trains on the network, reflecting both reliability and national engineering pride.
