If the weather cooperates we are planning on doing a day trip to Hallstatt from Salzburg in September. I have decided to try to take the 7:12am train to Obertraun and then probably the 6:32pm train from Hallstatt to Salzburg. Can I buy both tickets at the train station in Salzburg so I don't need to worry about getting a ticket in Hallstatt? When I look at prices online it says that the standard ticket is not restricted to a specific train so I was thinking if we decided to leave on an earlier train it wouldn't be a problem. Is that correct? Would I be able to type in a different departure station on the ticket machines to buy the second ticket?
