Overview
- State broadcaster CCTV reported the trial peak on the Shanghai–Chongqing–Chengdu route, with Science and Technology Daily describing the train as the world’s fastest EMU.
- Developers plan near‑commercial trials on the Chengdu–Chongqing central line next year, and entry to service could follow in 2026 if testing and regulatory steps are completed.
- Despite the higher test speed, the train is engineered for a maximum commercial operating speed of 400 km/h.
- Design changes include a 15‑meter nose, a roofline lowered by 20 centimeters, enclosed bogies, and roughly 50 tons of weight reduction, contributing to about a 22% cut in aerodynamic resistance.
- Permanent‑magnet synchronous motors raise efficiency by just over 3%, helping the CR450 accelerate from 0 to 350 km/h in about 4 minutes 40 seconds with lower interior noise reported at cruise.
