I am planning a train trip from Lyon (France) to Dresden (Germany). I am looking for information on whether the following trains are likely to be more crowded on a weekend or a weekday. I strongly prefer to avoid crowds on this trip due to having to move with heavy and fragile luggage, as well as animals. Tentative travel dates are Feb 11 Sun or Feb 12 Mon.
I would also appreciate tips on where I could look up this information myself. Do the train companies make statistics public?
Update: I just found out that Feb 12 is Fasching in Germany. Is this likely to cause increased traffic on that day?
