Sparschiene tickets can be booked online with no restrictions in either direction for all night trains (NJ/EN) and for day trains to Germany, Switzerland and the Netherlands.
Sparschiene tickets to Italy, Poland, Slovenia, the Czech Republic, Slovakia, Croatia and Hungary can be booked online for the most important cities along direct connections and collected from ticket machines. However, for technical reasons, return tickets from these countries can only be booked together with the outward journey. Online tickets to Hungary and the Czech Republic must be validated by the train attendant with a ticket punch. Passengers must request this from the Austrian train attendant on the outward journey. The ticket inspection receipt must be kept until the end of the return journey and presented if requested.
