China's self-developed high-speed rail tech is racing into the future 🚄✨. From icy tracks in the northeast to record-breaking speeds, Chinese mainland engineers are pushing boundaries this year.
Recently, the Shenyang-Baihe high-speed railway in northeastern Chinese mainland took off with Fuxing CR400BF-GS EMUs built for extreme cold 🥶, ensuring reliable service in frosty conditions.
Construction also leveled up with smart manufacturing: 'base-like' track slabs measuring 5.6 m by 2.5 m are now produced in just 10 minutes each, and height variations are kept within the thickness of a human hair, says Yang Zhenhua of China Railway No. 9 Group Co., Ltd. ⚙️
Further upping the ante, the world's fastest bullet train—the CR450—has begun pre-service trials on a high-speed line in Chinese mainland, hitting 453 km/h and a record relative passing speed of 896 km/h 🚀🔥.
To conquer the aerodynamic challenge, designers stretched the nose, lowered the roofline by 20 cm, and cut 50 tonnes of weight, slashing air drag by 22% and setting the stage for even faster runs.
Beyond steel and speed, China’s high-speed rail boasts an 'intelligent brain': the CTCS-3 ATP and ATO system, developed by CRSC Research & Design Institute Group Co., Ltd., supports autonomous inter-station operation, overspeed protection, and precise stopping—even in foggy or low-visibility weather—notes Jiang Ming.
For lines in western Chinese mainland, a new-generation train control system taps into the BeiDou Navigation Satellite System, blending satellite data, electronic maps, and onboard sensors to boost positioning precision and reliability.
Looking ahead, China’s high-speed network is on track to surpass 50,000 km by end of 2025, evolving into an extensive, intelligent, and resilient web that’s ready for tomorrow’s journeys 🌐🚅.
