China moves forward on next-generation high-speed rail

China has moved to the testing stage for its next-generation high-speed train, the CR450.

Engineers launched a test model from Yichang North Station along the Shanghai-Chongqing-Chengdu high-speed railway, with the train heading toward Wuhan.

Newsweek reached out to China’s Ministry of Transport via email for comment.
Why It Matters

China operates the world’s most extensive high-speed rail network, with more than 24,855 miles of operational lines, according to a 2023 report from the International Union of Railways. The arrival of the CR450 could further enhance the country’s reputation as the world leader in high-speed rail technology, promising faster, safer, and more energy-efficient transportation options. China alone accounts for nearly double the combined length of the rest of the world’s high-speed rail systems.

What To Know

Tests on the CR450 model will continue for around two weeks to validate performance and collect data for system optimization.

The CR450 prototype is designed to reach test speeds of up to 450 kilometers per hour (279.6 mph), with an intended operational speed of 400 km/h.

Once launched commercially, it will become the world’s fastest high-speed train, surpassing China’s current CR400 model, which operates at 350 km/h.

According to the China State Railway Group, the CR450 will feature a 22 percent reduction in overall operational resistance and a 10 percent decrease in weight compared to its predecessors.

The prototypes, which were first unveiled last year, are designed with an eight-car formation comprising four powered and four non-powered carriages, according to train manufacturer CRRC.

China’s high-speed rail network exceeded 46,000 kilometers by the end of last year. The country added over 3,100 kilometers of new railway in 2024 alone, including 2,457 kilometers of high-speed track, and its overall network now reaches more than 160,000 kilometers.

Although it reached test speeds of 450 km/h, authorities stated that the train’s operating speed was 400 km/h.

According to China Daily, the CR450 has a braking response time of about 1.7 seconds.
What People Are Saying

Lin Jian, a spokesperson for the Chinese Foreign Ministry, on X, formerly Twitter, in December: “With a test speed of 450 km/h and an operational speed of 400 km/h, it’s set to be the fastest high-speed train in the world! Faster, safer, more energy-efficient, more comfortable, and smarter!”
What Happens Next

The CR450 test phase is expected to last approximately two weeks, with commercial operations of the upgraded rail section scheduled to commence in the second half of 2025.
