According to the latest data from China Railway Group Corporation, as of the end of 2024, the operating mileage of high-speed railways in China has reached 48000 kilometers, accounting for over 70% of the total global high-speed railway mileage. The high-speed train has transported a total of 22.9 billion passengers, making it the world's largest and technologically advanced high-speed railway network.

At the 12th World High Speed Railway Conference, China showcased its latest research and development achievements. The CR450BF high-speed train developed by CRRC Changchun Railway Vehicles Co., Ltd. is undergoing type testing. The designed speed of this model is 450 kilometers per hour, with a maximum operating speed of 400 kilometers per hour, achieving significant breakthroughs in drag reduction, energy consumption reduction, and noise reduction. Experts from China Academy of Railway Sciences Group Co., Ltd. stated that the vehicle model is expected to be put into commercial operation soon.

China's high-speed rail construction technology also maintains a leading position. The HSP advanced geological prediction system developed by China Railway Academy has been applied to more than 350 tunnel boring machines, with a prediction accuracy rate of 90%. The train control system developed by China Railway Signal&Communication Research and Design Institute Group has achieved 100% autonomy and has been successfully applied to international projects such as the Hungary Serbia railway and the Jakarta Bandung high-speed railway in Indonesia.

At present, 81.5% of the construction of the main channels of China's eight vertical and eight horizontal high-speed railways has been completed, and major channels such as Beijing Shanghai, Beijing Harbin, and Shanghai Kunming have been connected. China Railway Group Corporation Limited stated that it will continue to promote the CR450 technology innovation project, consolidate China's leading advantage in high-speed rail technology, and provide Chinese solutions for the development of global rail transit.
