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.

And they thunder around at 300-360km/h all day every day.

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