China has demonstrated a next-generation maglev (magnetic levitation) train system capable of reaching around 400 miles per hour (≈650 km/h) in just seven seconds during controlled testing. Unlike conventional rail, maglev trains float above the track using magnetic forces, eliminating wheel-rail friction entirely. The record focuses on acceleration, not sustained cruising speed. Such rapid acceleration is possible because maglev systems distribute force evenly along the train, reducing mechanic
