The CR450 series lead the field with superior performance metrics, including operational speed, energy efficiency, in-cabin noise level, and braking distance. Highlights include:
- Increased Speed : With testing speed up to 450 km/h (280 mph) and operational speed of 400 km/h, the CR450 aims to significantly reduce travel time, offering a faster and more efficient travel experience.
- Advanced Safety : The trains feature shorter braking distance and enhanced stability, maintaining safety even at increased speeds.
- Energy Efficiency : The design reduces overall train resistance by 22% and weight by 10%, contributing to a greener footprint.
- Enhanced Comfort : Improvements in the comfort index, a 2-decibel reduction in cabin noise, and a 4% increase in service space ensure a more enjoyable and relaxing journey for passengers.
- Intelligent Technology : Comprehensive technological upgrades in areas such as train control and driving, intelligent driver interaction, safety monitoring, and passenger services ensure a smarter, more efficient, and safer travel experience for passengers and operators alike.
The CR450 EMU prototype incorporates breakthrough technologies in safe high-speed operation, reduced drag and consumption, vibration and noise control, comprehensive lightweight construction, and integrated intelligent design. The suite of innovations not only constructs a robust technological framework for 400 km/h electrical multiple units (EMUs) but also fosters comprehensive advancements in theory, technology, equipment, standards, and management practices, propelling forward the global high-speed rail technology landscape.
