Following the unveiling of the world’s fastest high-speed train in China, CRRC has provided further details on the CR450 model.
On 29 December 2024, the CR450 electric multiple units (EMU) was officially presented in Beijing. Developed as part of the CR450 Science and Technology Innovation Project, the prototype comprises two models: the CR450AF and CR450BF. These models have been designed and manufactured by subsidiaries of CRRC Corporation Limited—Qingdao CRRC Sifang Rolling Stock Co., Ltd. and CRRC Changchun Railway Vehicles Co., Ltd., respectively.

The trains are engineered for speeds of up to 400 km/h (249 mph) with a testing speed reaching 450 km/h (280 mph), advancing high-speed rail capabilities.
The CR450 series introduces various enhancements in speed, safety, efficiency, and passenger experience. Notable developments include:
- Increased Speed: The trains are designed to operate at 400 km/h, with a maximum tested speed of 450 km/h, aiming to reduce travel time between major destinations.
- Safety Enhancements: Improvements include a shorter braking distance and increased stability, ensuring safety at higher speeds.
- Energy Efficiency: Aerodynamic refinements have reduced overall train resistance by 22%, while a 10% reduction in weight contributes to lower energy consumption.
- Passenger Comfort: Modifications such as a 2-decibel reduction in cabin noise and a 4% increase in available service space are intended to enhance the passenger experience.
The incorporation of advanced train control systems, intelligent driver interaction, safety monitoring, and enhanced passenger services aims to improve operational efficiency.

The CR450 EMU integrates developments in several key areas, including high-speed operational safety, aerodynamics, noise and vibration control, lightweight construction, and smart system integration for monitoring and automation.
These advancements contribute to the framework for future high-speed EMUs, supporting broader progress in rail technology, equipment development, operational standards, and management practices.
