I know exactly which train I want and the time it is leaving (EC75 Franz Schubert, 8.39 on 6 July), but when I use eShop on cd.cz it says:
Note: For the train connection you have selected, it is possible to purchase a ticket starting on 7.7.2013 and then it directs me to trains later that day.
Does this mean that there are no tickets available for 6 July?
Can anyone shed any light on this?
Also, I'm exploring the option of using Westbus instead. Does anyone recommend a particular bus service other than them for a Prague to Vienna direct? Their fare works out to be a little more than the train.
