Also, on the French trains the connection platform numbers are only announced in French, so good luck if you're not a native speaker. Italian and German trains announce connections in English and also have LCD monitors on the bulkheads. All in all, I found the French train system the worst in Europe.
(Also, the new French booking app and website is train-wreck level of broken awfulness. And forget trying to book a train ticket across a national border, or several!)
