Changes

If you travel far you probably want to take TGV but in many stations they check the tickets for TGV on the entry to the platform which makes it kind of impossible to get in and you need to take TER. TER are not bad but it's probably still better to know where can you enter the fast trains. We tried once to ask the controlers on the gates if they could write us fine directly and let us in but they said that we can't get in without paying.

Stations were they don`t check tickets before going to TGV:
