Next generation

On Dec 29, China unveiled two CR450 high-speed train prototypes, which are capable of reaching a test speed of 450 km/h and an operational speed of 400 km/h. They will be the fastest high-speed trains in the world once they enter commercial service, surpassing China's current CR400, which operates at 350 km/h.

It was one of the most exciting developments in the railway sector in 2024. This leap in speed and comfort reflects China's ongoing leadership in high-speed rail technology.

The two prototypes, with their futuristic design, have reduced weight by 10 percent to improve fuel efficiency. To decrease rolling resistance, the development team wrapped the trains' running gear — such as the wheels, axles and suspension system — partly, marking a breakthrough in railway engineering.

The interiors of the prototypes are also cutting-edge. In business class, the seats can be adjusted to a meeting mode, allowing them to be arranged face-to-face, transforming the compartment into a conference room at any time.

In economy class, the seats are ergonomically designed for greater comfort, with curves that better suit the body. In response to passenger smartphone use, small tables in economy class now feature a rack that enables passengers to prop up their phones to watch videos.
