The CR450 high-speed train will be the fastest train in the world when it enters commercial service. Its two prototypes unveiled in Beijing on Sunday had a test speed of 450 kilometers per hour and an operational speed of 400 km/h.

The CR400, which is in service since 2017, has an operational speed of 350 km/h. The CR450's speed advantage comes with a number of other improved features, such as a braking system with a shorter response time, crucial for the safety of high-speed trains. After a series of trials and calculations, engineers have improved the CR450's braking response time from an initial 2.3 seconds to about 1.7 seconds.

The CR450 has carbon fiber composite materials, reducing its overall weight, which not only helps in enhancing speed but also significantly aids in energy consumption reduction. Thus, the CR450 balances technological empowerment for increased efficiency with a reduction in energy consumption.

On the foundation of raised speed, guaranteed safety and effective energy conservation, the CR450 also focuses on enhancing the passenger experience. It features built-in four-person compartments and business seats that can rotate and adjust up to 300 degrees, creating a clean and simple environment with a high level of comfort.

The research and manufacture of the CR450 will also drive the coordinated development of multiple industry chains related to the railway industry, further improving the overall quality of the high-speed rail industry chain and laying a more solid foundation for technological innovation in China's railways. By far, China already has the largest operating high-speed rail network in the world, which plays an important role in promoting regional integrated development in the vast country.

Domestic high-speed trains have a name, "Fuxing", which means rejuvenation. The trains have lived up to that name — realizing the grand dream of rejuvenation for the 1.4 billion Chinese people as they speed into the future.
