Hello fellow travelers,
For train from Vienna to Budapest, I found that there are RailJet, EC and D. I found information on the former 2 types of train, but not the D train. We are planning to travel this journey during a weekday morning around 11:00.
(1) Is it correct that there is no seat reservation available on the D train?
(2) How does the D train compare to RailJet or EC train?
(3) In general, is it necessary to make seat reservation, regardless the type of train, in this journey?
(4) Is it the earlier I can buy the tickets, the better the price?
(5) Does the train in this journey ever get full?
Best regards,
FJ
