We'll be traveling via train from Lake Bled to Vienna on the train after our Rick Steves tour ends. How does luggage work on the train? I can't seem to find an answer on the ÖBB website.
You put your bags on a shelf or on the floor.
You handle your own luggage on trains. Often there is space at the end of cars for luggage, and a smallish overhead shelf above your seats.
Good information, and photos, are at this great source for all things train:
