China has run at 360kmh before, but last I checked they mostly run slower.
Air resistance is a killer as you go faster. So for trains 300 is usually about the best compromise between energy use and speed. If you want to go faster a jet at altitude is going to be much faster at a better fuel efficiency. High speeds make sense for long distances.
