A protype high-speed train in China that reaches a test speed of 279mph will be the “fastest” in the world. The new CR450, which is currently undergoing tests on Beijing railway lines, was first revealed in prototype in December 2024. 

The train is expected to normally run at 248mph. Operating on a magnet traction system, the trains are significantly faster than the CR400 Fuxing, also high-speed and currently in service, which operates at 217mph. So, what are these trains like?
