On December 29, 2024, two samples (样车) of the CR450 high-speed train were shown in Beijing. This wonderful train can reach a test speed of 450 km/h and an operating (运行) speed of 400 km/h. When it starts to be used for business, it will be the quickest high-speed train in the world, much faster than the CR400 that runs at 350 km/h.
The China State Railway Group, which made this train, said that the CR450 has set new world standards (标准) in many important parts like speed, using less energy, making less noise, and having better braking (刹车) performance. Even though it goes at a higher speed, its braking is as good as the 350 km/h trains. This is because of the great engineering work that keeps the train steady (平稳的) and safe even when it's fast.
The CR450 also cares a lot about making passengers (乘客) feel comfortable. By using good noise-cutting technology, the inside of the train is as quiet as the 350 km/h trains. What's more, its running resistance (阻力) has been reduced by 22 per cent and its weight has been cut down by 10 per cent, which helps to save energy. The inside has been made again, with 4 per cent more room, and there are better places to put luggage (行李).
Two samples were shown on that day. They were made by different companies, but both want to give passengers a nice trip. The China State Railway Group will do more tests to make sure the train is okay for business use.
Since 2012, China's railway has made many new things, like the Fuxing high-speed train, and has built a whole high-speed rail technology system. The CR450 shows China's ability to make new helps the railway grow.
In the past 15 years, China has built a very big railway network, including the world's largest and best high-speed rail network, which is very long. The CR450 is an important step in China's railway growth.
