With a test speed of up to 450 km/h, the CR450 can reach 400 km/h in actual operation, making it the fastest passenger train in the world. Leaked images also show the CR450 train with 8 cars, with a multi-angled arrow design.

According to official data, the CR450 hull weighs around 10 tonnes, 12% lighter than the current CR400 model. Energy consumption has been reduced by 20%, while braking performance has been similarly improved. These improvements increase commercial operating speeds by 50 km/h, without affecting the braking distance, noise level or energy efficiency of the train. The CR450 achieved a record speed of 453 km/h during a performance test conducted in June last year.

The CR450 project is part of China's 14th five-year plan, an initiative that also includes upgrading high-speed rail infrastructure such as tracks, bridges and tunnels. The Chengdu-Chongqing line, which is built to a higher standard, is considered a priority line for the CR450 to operate at its maximum designed speed. Meanwhile, the Beijing-Shanghai line is considered in need of upgrading to ensure the CR450 can safely operate at its highest speed.

Today, China's high-speed rail system is the world's largest network in operation, covering more than 45,000 km.
