Prototypes of the CR450 bullet train, with a test speed of up to 450 kilometers per hour and an operational speed of 400 kilometers per hour, highlights China's cutting-edge advancements in rail technology and contributions to the global rail industry.

The CR450 is significantly faster than the CR400 Fuxing high-speed trains currently in service, which operate at speeds of 350 kilometers per hour.

The China State Railway Group Co., Ltd. (China Railway) currently is arranging line tests for the prototypes and optimize technical indicators to ensure the CR450 enters commercial service as soon as possible.
