• That’s the case in any country with high speed rail: tracks are the devils of the details.

    I mean in the end, especially with a country as small as France, there’s not a whole lot of difference between 320 and 350km/h. (I mean going one end of China to the other and that difference adds up, but not one end of France to the other.)

    But … what’s stopping them from making the track changes needed?
