Core Points - The CR450 technology innovation project, part of the "14th Five-Year Plan," was launched in 2021, with the prototype unveiled at the end of last year, achieving a record speed of 453 km/h for a single train and 896 km/h for relative crossing speed [1] - The CR450 train is currently undergoing operational assessment, which involves extensive mileage testing, with a requirement to complete 600,000 kilometers before it can carry passengers [3][5] - The CR450 features significant design improvements, including a longer and more aerodynamic train head, a fully covered bogie, a lower car body height, and a weight reduction of 50 tons, resulting in a 22% decrease in aerodynamic drag [9] Technical Performance - The CR450 can accelerate from a standstill to 350 km/h in just 4 minutes and 40 seconds, compared to 6 minutes and 20 seconds for the existing 350 km/h Fuxing train, indicating a 100-second improvement in acceleration time [9] - The train's design enhancements, such as a 15-meter long head and a lower skirt, contribute to reduced air resistance and improved performance [9]
