It would take a 500 km/h train to cover 170 km in 20 minutes. I think only maglevs [1] approach that speed.

- divbzero 4y agoI suppose so? The Shanghai maglev train [2] might be the only high-speed maglev in operation [3]. The train has a cruising speed of 431 km/h, but averages 250 km/h in actual operation — covering 30 km in 8 minutes with no stops in the middle.
