The world’s fastest train, CR450, developed by China, is undergoing type testing on Beijing Ring Railway. The train has a test speed of 450 kilometres per hour and a commercial operating speed of 400 kilometres per hour—100 kilometres per hour faster than the earlier CR400 Fuxing. According to Wang Feng, Vice President of CRRC Corporation, the CR450 high-speed train represents a new benchmark in technology, safety and operational systems. To achieve higher speeds, the train’s traction capacity, dynamic performance and pantograph system have been upgraded. It features a water-cooled permanent magnet traction system, a new generation of high-stability bogies, and AI-enabled multi-system technologies. The train is equipped with more than 4,000 sensors that monitor movement, car body condition, traction, braking and fire detection systems in real time. Thanks to the use of lightweight materials, the train’s overall weight has been reduced by 10 per cent, while air resistance during operation has been cut by 22 per cent. Special materials and aerodynamic design have also been used to reduce noise, lowering cabin noise levels by 2 decibels.
