Two prototypes of the CR450 high-speed train, unveiled on Dec 29 in Beijing, are capable of reaching a test speed of 450 kilometers per hour and an operational speed of 400 km/h, which will make it the fastest train in the world once it enters commercial service.

The CR450, manufactured by CRRC Qingdao Sifang Co Ltd, outshines the CR400, which operates at 350 km/h.

An operating speed of 400 kilometers per hour is globally considered a milestone for high-speed rail. The release of this prototype train signifies a significant breakthrough for China, greatly enhancing the country's level of railway technology and technological self-reliance. It will further consolidate and expand China's leading position in high-speed rail technology worldwide.

According to Tao Guidong, deputy chief engineer of CRRC Sifang Co, the design inspiration for the CR450AF's train head comes from a flying arrow, with sharp-edged lines resembling ancient Chinese arrowheads.

Building upon the foundation of the CR400 Fuxing high-speed electrical multiple unit, the CR450 high-speed train set has undergone comprehensive upgrades in technology. It has achieved breakthroughs in three major technological systems: drag reduction/energy conservation, vibration reduction/noise control, and comprehensive lightweight system integration. Key technologies include high-power permanent magnet traction, time-sensitive train network communication, multi-level control braking systems, and high-speed safety bogies.
