The world’s second-fastest high-speed prepare is scheduled for commercialization in Korea after 2031. That is anticipated to considerably scale back journey time between main cities nationwide to inside one hour.
The Ministry of Land, Infrastructure, and Transport introduced on Dec. 22 that it has accomplished the event of core know-how for the next-generation high-speed prepare (EMU-370), which has a industrial working pace of 370 km/h (design most pace of 407 km/h), via a nationwide analysis and improvement (R&D) mission. Accordingly, automobile manufacturing will start subsequent 12 months, with take a look at runs deliberate for round 2030 and commercialization scheduled for after 2031. A industrial working pace of 370 km/h is the second-fastest on this planet, following China’s CR450 (400 km/h), which is at present present process take a look at runs. The industrial working pace of high-speed railways in main nations equivalent to France, Germany, and Japan is at present round 320 km/h. To develop this high-speed railway, the federal government designated the Korea Railroad Analysis Institute because the lead group and has invested a complete of twenty-two.5 billion gained over 4 years since 2022.
The six core applied sciences developed embody a high-speed motor and discount of operating resistance. The high-speed motor was developed as a 560 kW high-efficiency product via optimum design, together with miniaturization and high-density integration of main elements, improved cooling efficiency, and enhanced insulation efficiency. This represents a 47.4% improve in output in comparison with the present KTX-Cheongryong (380 kW). Moreover, operating resistance was decreased by greater than 10% in comparison with the KTX-Cheongryong by designing a smoother entrance finish and minimizing the protrusion of the rooftop air conditioner. Operating stability and inside noise discount have been additionally improved. By the optimum design of the suspension system, together with air springs and dampers on the powered bogie, lateral vibration acceleration was decreased by greater than 30%. The construction of the automotive physique’s extruded supplies for the ground and facet partitions was optimized, lowering inside noise by 2 dB in comparison with earlier fashions. Moreover, hermetic and sound-insulating applied sciences have been secured to localize the manufacturing of hermetic gangways, and efficiency analysis and security verification requirements have been established for the automotive physique gear, operating, braking, and propulsion programs, and signaling gear.
The federal government plans to put an order for the newly developed high-speed prepare within the first half of subsequent 12 months and deploy it on some sections ranging from early 2030. That is anticipated to considerably scale back journey instances between main cities nationwide to inside one hour. As well as, it’s assessed that this can create a chance to preemptively safe a place within the export marketplace for high-speed railways of 350 km/h class or larger. It’s identified that nations like Vietnam and Poland are at present making ready to construct 350 km/h class high-speed railway networks. An official from the Ministry of Land, Infrastructure, and Transport defined, “We plan to conduct take a look at runs of the primary one or two EMU-370 trainsets on sections such because the Pyeongtaek-Osong line from early 2030,” and added, “If the EMU-370 establishes itself as the primary high-speed prepare in Korea, your entire nation will successfully be related as a single dwelling sphere, and it’ll additionally lay the groundwork for abroad exports.”
