The ticket machine is programmed to show the timetable times as per the scheduled timetable. This is intentional so that passengers can find their way around and easily orientate themselves.
Any delays are therefore not displayed on the ticket machine itself. These can be viewed at any time on the display boards in the bus stop area or at the ÖBB ticket desk. The relevant ÖBB staff will also be happy to provide information.
For your information: The connections and times displayed on the ticket machine are purely information about the next scheduled connections. ÖBB standard tickets are valid on all ÖBB trains (except night trains) for the selected route for 2 days from the point at which they become valid. This means that any other connection that runs on this route can also be used within these two days.
