跑出新速度！全球最快动车组CR450正在开展运用考核

Core Viewpoint - The development goal of China's transportation industry is to achieve seamless travel for people and goods, with significant advancements made during the "14th Five-Year Plan" period, including the establishment of the world's largest high-speed rail network, expressway network, and postal express network, totaling over 6 million kilometers in comprehensive transportation infrastructure [1]. Group 1: Transportation Network Development - The main framework of China's national comprehensive transportation network has been largely completed, consisting of 6 main axes, 7 corridors, and 8 channels, connecting over 80% of county-level administrative regions and serving approximately 90% of the country's economic and population total [2]. - The increasingly sophisticated transportation network supports high-quality economic development and enhances travel convenience, with over 2.4 billion people traveling across regions during the recent holiday period, averaging over 300 million daily trips [2]. Group 2: High-Speed Rail Innovations - China's high-speed rail has set a benchmark with a commercial operating speed of 350 km/h by the end of the "13th Five-Year Plan," and continues to innovate beyond this standard [3]. - The CR450 technology innovation project, one of the major projects in the "14th Five-Year Plan," was launched in 2021, with the prototype released at the end of last year, achieving a record speed of 453 km/h for a single train and 896 km/h for relative meeting speed during various tests [5]. Group 3: CR450 Train Performance - The CR450, known as the "world's fastest high-speed train," is currently undergoing operational assessments on the Shanghai-Chongqing-Chengdu high-speed rail, with ongoing tests to meet the required operational standards [6][7]. - The CR450's design improvements include a longer and more aerodynamic train head, reduced weight by 50 tons, and a 22% decrease in drag, allowing it to accelerate from 0 to 350 km/h in just 4 minutes and 40 seconds, significantly faster than the previous model [11][13].
