ÖBB trains: Sparschiene fares, and the Vienna 72-hour pass

The Austrian railway's "Sparschiene" fares are discounted tickets for a specific train, released months ahead and cheapest early; Vienna–Salzburg can cost a fraction of the standard fare. In Vienna, the transport network is one of Europe's best and a 24/48/72-hour pass covers metro, trams, and buses; the city's own pass is cheaper than the tourist card unless you'll use the card's museum discounts. Validate the pass once in the blue machine.
