The CR450 high-speed train with a speed of 400 kilometers per hour has been released for operation i

The test speed is 450 kilometers per hour, and the operating speed is 400 kilometers per hour. Today, the CR450 high-speed train prototype, a new member of China's high-speed rail, was released in Beijing, further consolidating and expanding China's leading advantage in high-speed rail technology.

If the CR450 high-speed train can be put into use on the Beijing Shanghai and Beijing Guangzhou high-speed railways, the travel time between Beijing and Shanghai and between Beijing and Guangzhou is expected to be shortened to 3 and a half hours and 6 hours respectively.

It is understood that the CR450 high-speed train prototype has internationally leading indicators such as operating speed, energy consumption, interior noise, and braking distance. One is higher speed. The experimental speed is 450 kilometers per hour, and the operating speed is 400 kilometers per hour. After commercial operation in the future, it can further compress the distance between time and space, making passenger travel more convenient and efficient. Secondly, it is safer. The braking distance is shorter and the running stability is better. With the increase of operating speed, the braking distance is basically the same. Thirdly, it is more energy-efficient. The running resistance of the high-speed train is reduced by 22% and the weight is reduced by 10%. Fourthly, it is more comfortable. The comfort index is better, the interior noise is reduced by two decibels, and the passenger compartment service space is increased by 4%, providing passengers with diversified, convenient, and personalized services and a better riding experience.

Next, China Railway Group will arrange a series of line tests and assessments for CR450 high-speed trains, further testing their performance, continuously optimizing technical indicators, and striving to put them into commercial operation as soon as possible to serve the people's beautiful travel life.
