> Look for using Bus like Flixbus as an alternative if possible. They are not perfect but more reliable than the DB train for sure.

I wouldn't recommend that, at least not for longer rides. Apart from the fact that I don't trust their overworked drivers (there was a big accident this year that may have been caused by a conflict between the drivers, according to some witness reports), its cheapness also tends to attract rather unsavoury individuals. I have all sorts of horror stories, from the guy (probably on some drugs) who started shouting multiple times in the middle of the night, to some dude who fell asleep with his orange juice bottle still open, which then spilled all over me, to the guy who thought it was a good idea to take drugs across the Swiss border (which caused a massive delay as, of course, his baggage was then extensively searched), etc. I've met weird people on trains too, but Flixbus is a whole other level.
