On December 29, the prototype of the CR450 Electric Multiple Unit (EMU) was unveiled in Beijing, marking a major step forward in the "CR450 Scientific and Technological Innovation Project". Once in service, the CR450 EMU will be the world's fastest high-speed train with an operating speed of 400 kilometers per hour.
The CR450 EMU prototype features several key improvements:
Higher Speed: It can reach a test speed of 450 km/h, with an operating speed of 400 km/h.
Improved safety: The braking distance is shorter and the operating stability is better. Despite the higher speed, the braking distance is similar to that of a 350 km/h EMU.
Increased energy efficiency: Rolling resistance is reduced by 22% and weight is reduced by 10%.
Improved comfort: Interior noise is reduced by 2 decibels and passenger space is increased by 4%.
Advanced Intelligence: Improvements include better train control, rider safety monitoring and passenger services.
The CR450 prototype has lost approximately 40 tons and reduced energy consumption by 20%. Test data shows its body is 12% lighter than the existing CR400 Fuxing Hao train. Running resistance and energy consumption have been reduced by 20%, while braking and traction efficiency have increased by 20% and 3%, respectively. As a result, the train can reach 400 km/h with the same braking distance, noise level and energy consumption.
The CR450 uses advanced materials such as permanent magnets, magnesium alloys and carbon fiber. The train now weighs more than 460 tons and has a tractive power of up to 11,000 kilowatts. Improved brakes ensure safe stops even at 400 km/h. Acceleration and deceleration times have been reduced by about 12 percent and energy consumption by 20 percent.
