Korea develops tech for world’s 2nd-fastest train capable of 229 mph

South Korea has completed the development of core technologies for a next-generation high-speed train, the EMU-370, which is designed to operate at speeds up to 229 mph (370 kph) with a maximum technical speed of 253 mph (407 kph). This would make it the world’s second-fastest high-speed train after China’s CR450, which is expected to enter commercial service in 2027 at 249 mph (400 kph). The project, led by the Korea Railroad Research Institute and involving seven public and private organizations, ran from April 2022 to December 2025 with a total investment of about $15.23 million. Manufacturing of the first trains is planned to start next year, with test operations in 2030 and commercialization after 2031. The development delivered six core technologies, including a high-speed traction motor with 560 kW output—a 47.4% increase over the existing KTX-Cheongryong motor—and measures to
