Missing the point

Yes taxation rates matter. But France-Spain and France-Belgium trains are expensive to take *because the capacity is too low*

If you reduce ticket prices on those routes you WON’T TRANSPORT MORE PEOPLE. Just different people. As the trains are full anyway

So, Clement Beaune, how are you going to get more TGVs to Barcelona?

Why are flights cheaper than trains in Europe?

Train travel is often more expensive than flying. Could taxing aviation to invest in the rail industry help change that?

And if your response is “ah but rail firms will add more capacity”, I’d point you to Thalys that hasn’t upped capacity in 2 decades despite rising demand and sky high prices. And SNCF that runs just 2 TGVs to Barcelona a day. Both easy to solve, both not done.
@jon How does Renfe's new BCN-Lyon service factor into all of this? Obviously not much right now (are they still only at 1 train per day?), but Renfe, despite their bad record on the subject MAD-BCN, is expressing interest in adding frequencies BCN-Lyon, and eventually extending their trains Part Dieu-GdL. Which is significantly more interest than SNCF has offered lately.

@SicTransitPHL at the moment Renfe + SNCF are *separately* running the same number of trains FR-ES they used to when collaborating. So so far 🤷‍♂️

Medium term Renfe does See opportunities in France though - and its Series 106 AVE ought to be approved for France. So medium term there’s a little hope.

@jon @SicTransitPHL Also nice that Marseille-Madrid is back, even if 1 train per day is way too little. And I've never seen such a bad ticket purchasing website as Renfe's, I had to book through Trainline.
@DiegoBeghin @SicTransitPHL Spain is pretty much the only country I can solidly recommend using Trainline 🙂
