@HaTetsu TGVs aren't priced per kilometre. Fairer to say that they're priced per leg based on demand and how much the SNCF thinks they can get away with restricting supply e.g. today Paris - Le Mans: €70, 1h, 200km Paris - Nice: €80, 6h, 900km so if you divide by km on one of the longest journeys in the country they look very cheap
