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.
周日，两辆CR450高铁样车在北京发布，测试速度可达450公里/小时，运行速度可达400公里/小时，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。
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.
据领导CR450列车研发的中国国家铁路集团称，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。
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.
尽管CR450的速度更高，但它的制动效率与时速350公里的列车相似——这是重大工程进步的结果，确保了列车在更高速度下的稳定性、性能和安全性。
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.
CR450的一个突出特点是其卓越的能源效率。列车的运行阻力降低了22%，重量减轻了10%，从而提高了燃油效率。尽管速度有所提高，但这些优化有助于最大限度地减少能耗。
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.
CR450还优先考虑乘客的舒适性，旨在提供平稳安静的乘坐，即使在400公里/小时的速度下。先进的降噪技术确保车内噪音水平与时速350公里的列车相当，提供宁静的旅行体验。
The train's interior has been redesigned for added comfort and convenience, increasing cabin space by 4 percent.
为了增加舒适性和便利性，列车内部进行了重新设计，车厢空间增加了4%
Adjustable luggage racks and a versatile storage area cater to passenger needs, including accommodating bicycles, wheelchairs and other items. These innovations were made in anticipation of potential regulatory changes in passenger transportation.
可调节的行李架和多功能存储区满足乘客的需求，包括容纳自行车，轮椅和其他物品。这些创新是在预期客运管理可能发生变化的情况下进行的。
