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, were debuted in Beijing recently, highlighting 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 a series of line tests for the prototypes and optimize technical indicators to ensure the CR450 enters commercial service as soon as possible. (Xinhua/Xing Guangli)
