What distance can a TGV cover?

Question

distance it can cover per journey to any where

Answer 1

I think that what you are trying to ask is what is the range of a TGV. If that is the question, the answer is that they are electrically powered and therefore there is no question of mpg or fuel capacity. They will, however, have a programmed maintenance programme, but what that is will have to await an answer from a SNCF expert.

Answer 2

As far as the tracks are laid.  ;-)

Answer 3

It can go all the way to the station where its route ends.
