China’s CR450 Bullet Train Breaks Speed Records

December 31, 2024

China has recently revealed its CR450 bullet train, achieved a remarkable speed of 450 km/h (approximately 280 mph) during testing. This development marks advancement from the previous CR400 Fuxing trains, which maxed out at 350 km/h. The CR450 combines speed with enhanced efficiency, promising to transform rail travel.

Key Features of the CR450

The CR450 is designed to be 12% lighter than its predecessor, consumes 20% less energy, and boasts a 20% improvement in braking performance. Passengers can expect a quieter and more spacious interior, thanks to advanced noise-reduction technologies.

Operational Speed and Safety Measures

Once in regular service, the CR450 is expected to operate at a top speed of 400 km/h (approximately 249 mph). The train is equipped with over 4,000 sensors to monitor critical systems, ensuring passenger safety, which also includes a multi-level emergency braking system for added security.

Aerodynamic Design and Energy Efficiency

The aerodynamic shape of the CR450, combined with lighter materials, reduces air resistance . This design enhancement leads to a 22% decrease in energy consumption, making the train more environmentally friendly.

China’s extensive high-speed rail network, which exceeds 46,000 kilometres, will greatly benefit from the CR450. The train is expected to shorten travel times on key routes, such as Beijing to Shanghai. Testing has been successfully conducted on various lines, including Zhengzhou-Wanzhou and Jinan-Zhengzhou.

Prototypes and Future Developments

The CR450 series includes two prototypes, the CR450AF and CR450BF. These models feature eight-car configurations and advanced water-cooled traction systems. They are designed for smooth high-speed operation, further reducing noise and weight.

The CR450 sets a new global standard for train speed and efficiency. It represents milestone for China’s transportation system and is poised to revolutionise rail travel, making it faster, safer, and more energy-efficient.
