In China, a train was accelerated to a record speed of 623 km/h with the prospect of acceleration to 2,000 km/h (video)
In China, the Hyperloop train has accelerated to 623 km/h. Ultimately, manufacturers want to build vehicles that can carry passengers at 2,000 km/h. Hyperloop trains operate by pushing magnetically levitating capsules through tunnels with very little air resistance. To test the train, engineers built a road about two kilometers long in a low-pressure vacuum tube. […]
