>That said the only other remarkable thing was how shaky the video was at 500km/h if the train was really moving around that much it wouldn't be too sustainable. I wondered the same, but have a feeling some of the shakiness was due to having zoomed in quite a bit on a camera without any kind of image stabilisation. In the video, the image of the speed indicator is very shaky but then you realise it is zoomed in on the screen at the other end of the train car. So maybe it's not quite -that- shaky as it may seem.
