      Yes,

      If it has an operating speed of 450km/h this would be impressive.

      But just reaching this speed is far from a world record, the French TGV record from 1990 is 513km/h, it reached 574.8km/h in 2007 which is the current world record.

          Wind resistance is a problem at speed which is why production trains rarely go faster. Airplanes at altitude see much less win resistance. (hyperloop would also be good but will never be reasonable to build even if the engineering challenges are overcome)

            Japanese bullet trains had to get a redesign due to something akin to sonic booms when leaving tunnels that annoyed the hell out of residents several times an hour.

              Noise is another issue of course but energy is what will kill faster trains for forever

      603 for maglevs, 574.8 for steel rail, set in France in 2007 by a hotted up, modified TGV.

      China holds the record for a stock train at 487, set in 2010.
