Core Viewpoint - The CR450 high-speed train, known as the "world's fastest high-speed train," has achieved significant speed records and is undergoing extensive testing to meet operational requirements before passenger service can begin [1][5]. Group 1: Speed Records and Testing - The CR450 has set a new record with a single train speed of 453 km/h and a relative meeting speed of 896 km/h during testing [1]. - The train is currently undergoing operational assessment on the Shanghai-Chongqing-Chengdu high-speed railway, which involves extensive mileage testing [1][5]. - To qualify for passenger service, the CR450 must complete 600,000 kilometers of testing while meeting all technical specifications [1]. Group 2: Design Improvements - The CR450 features a longer and more aerodynamic train head, extending from 12.5 meters to 15 meters, which reduces air resistance [7]. - The train's undercarriage has been designed with a fully enclosed bogie and a lower skirt, minimizing the visible wheel area and enhancing speed [9]. - The overall height of the CR450 has been reduced by 20 centimeters, and its weight has been decreased by 50 tons, resulting in a 22% reduction in drag over five years of development [11]. Group 3: Acceleration Performance - The CR450 can accelerate from a standstill to 350 km/h in just 4 minutes and 40 seconds, significantly faster than the previous model, which took 6 minutes and 20 seconds [13]. - This improvement in acceleration time represents a reduction of 100 seconds compared to the existing CR350 model [13]. Group 4: Future Testing Plans - Comprehensive testing of the CR450 will take place on the Chengdu-Chongqing line next year, simulating conditions closer to actual operations [14].
