320km/h
every performances have costs 
the japanese bullet is less compatible, runs shorter distances and cost more than $40 Million ...

I guess 320km/h is what it does in normal, everyday operations, with passengers.
It would be pretty lousy otherwise as even older Shinkansen or ICE can go 330+ (usually ~300 in normal operations).
As I understand it, the €30mil were spent additionally to the cost of the train, to make modifications to the wheels, engine and the track itself.
My question of how fast it could go without these was because for normal passengers, it would be much more interesting to see what they could get out of it without having their head spin (One TV report said that many of those onboard the record train felt dizzy after getting off).
Maybe I'm wrong but it feels like you think I wanted to insult the record or make it look less impressive - I was, however, just doubting it's usefulness a bit.
Potential buyers will know that the train can't do that with passengers and that a lot of parts would need to be replaced after every run. Plus, it would most likely be extremly noisy.
If you compare the geography of France/Europe to Japan you can easily see why (Shinkansen) trains that run even faster than the current models don't make much sense. It's difficult for them to build long, straight tracks so it makes much more sense for them to improve speed on curvy tracks.
