Why can I not find the Paris (Austerlitz) to Nice night train to make reservations? It’s not available through the Rail Planner app, it’s not available in the Eurail reservation system and it doesn’t even come up when I try through the French SNCF website. Yet SNCF has a whole page devoted to the Paris to Nice night train, with train times and train numbers. This would appear to be a valid route -- why can I not find it and book it?
(My plan is to travel only using night trains and this is supposed to be the very first leg of my journey. Frankly, this is not a great start if I can’t even book the first day of my trip.) Thank you.
