时速400公里！全球最快高铁列车来了

12月29日，CR450动车组样车在北京发布，这标志着“CR450科技创新工程”取 得重大突破。

未来，CR450动车组投入商业运营后，运营时速将达到400公里，成为全球跑最快的高铁列车。

Two prototypes of the CR450 high-speed train, unveiled on Sunday in Beijing, are capable of reaching a test speed of 450 kilometers per hour and an operational speed of 400 km/h, which will make the CR450 the fastest high-speed train in the world once it enters commercial service.

自2018年开始，在中国国家铁路集团有限公司组织下，国内科研院所、高校、企业等科研力量组成联合创新团队，在时速400公里商业运营技术“无人区”进行探索。

经过7年艰苦攻关，CR450动车组“成绩满满”，样车运营速度、运行能耗、车内噪声、制动距离等主要指标国际领先。

According to China State Railway Group, which led the development of the train, the CR450 has set new global benchmarks by excelling in key areas such as operational speed, energy efficiency, noise reduction and braking performance.

二是更安全。制动距离更短、运行稳定性更优，在运营速度提升的情况下，制动距离基本相当。

Despite its higher speed, the CR450 has braking efficiency similar to those of trains running at 350 km/h — a result of significant engineering advancements that ensure the train's stability, performance and safety at higher speeds.

三是更节能。动车组整车运行阻力降低22%，减重10%。

A standout feature of the CR450 is its exceptional energy efficiency. The train's running resistance has been reduced by 22 percent and its weight cut by 10 percent, leading to improved fuel efficiency. These optimizations help minimize energy consumption despite the increased speed.

四是更舒适。舒适度指标更优，车内噪声降低2分贝，客室服务空间增加4%，可为旅客提供多样化、便利化、个性化服务，乘坐体验更好。

The CR450 also prioritizes passenger comfort, aiming to offer a smooth and quiet ride, even at 400 km/h. Advanced noise-reduction technologies ensure that the interior noise levels are comparable to those of the 350 km/h trains, providing a peaceful travel experience. The train's interior has been redesigned for added comfort and convenience, increasing cabin space by 4 percent.
