I see now that both websites, DB and OBB offers the same price between München and Innsbruck, and Innsbruck and Venezia. Does it make any difference from where I buy the tickets? Would the train have German and Austrian cars or all are the same? If yes, is one better than the other? I also noticed that the price between Innsbruck and Vnezia is only EUR10 more for 1st class. Considering the 4:45 hrs train ride, is it worth the difference? Thanks for taking the time to replay!
