Amazing stuff!
"Researchers ... have accelerated a one-ton vehicle from a dead stop to 435 mph (700 km/h) in under two seconds – then back to zero mph on about a 1/4 mile (1,312 ft / 400 meter) magnetic levitation test track. ... That makes it the quickest superconducting maglev acceleration ever demonstrated. ...
But NUDT isn't stopping there. The eventual goal is to hit the 621 mph (1,000 km/h) mark, surpassing the typical 550-580 mph (885-933 km/h) that passenger planes generally cruise at. ...
Though called "high-temperature superconductors (HTS)," it actually operates using liquid nitrogen, closer to -321 °F (–196 °C) ..."
China’s record-smashing maglev achieves 0-700km/h acceleration in less than 2 seconds "Feat seen to catapult China into global top tier of ultra-high-speed maglev technology and unlock new possibilities for hyperloop transport"
