Core Viewpoint - The Chengyu Central Line high-speed railway has made significant progress with the successful completion of key construction works, paving the way for future developments and testing of the CR450 trainsets, which are expected to achieve operational speeds of up to 400 km/h [2][3]. Group 1: Project Progress - The Chengyu Central Line high-speed railway's construction, including the introduction of the line to Chengdu Station, has reached a critical milestone with the completion of signal replacement and line adjustment works on January 16, 2026 [2]. - The Chengyu Central Line is designed for a maximum speed of 350 km/h, with provisions for future upgrades to 400 km/h [2]. - The project has involved over 1,000 workers and more than 100 pieces of machinery, completing 643 meters of line adjustments and the activation of 3.2 kilometers of new track [9]. Group 2: CR450 Trainset Development - The CR450 trainsets, which include the CR450AF and CR450BF models, are being developed by CRRC Changchun Railway Vehicles and CRRC Qingdao Sifang, with testing expected to demonstrate world-leading performance by 2025 [3]. - The CR450 trainsets have already achieved a single train speed of 453 km/h during tests, with expectations for further speed records during upcoming trials [6][8]. - The CR450 trainsets incorporate advanced technologies aimed at reducing drag, noise, and weight, as well as enhancing power and communication systems [7]. Group 3: Future Testing and Expectations - The CR450 trainsets are set to undergo comprehensive testing on the Chengyu Central Line in 2026, which will be closer to operational conditions [6]. - Current expectations suggest that the CR450 trainsets could potentially reach test speeds of 450-460 km/h, positioning them as contenders for the fastest operational high-speed trains globally [8]. - The highest operational speed for existing Chinese high-speed trains is currently 350 km/h, with the CR400AF and CR400BF models achieving test speeds of up to 420 km/h [8].
