How did you buy your tickets? I can't seem to find this train.Edited: 3:21 am, March 21, 2018
tickets for this train service is purchasable only in ticket counters.
Tickets will probably be available online later this year!
online purchase is not possible yet but Austrian railways promiced to implement it soon.
Good news - OeBB implemented purchase on website (but exchange to paper ticket in OeBb ticket machine is mandatory)
Yeah I saw this reported on seat61.com twitter. Good news!
62.1 EUR for bed in 3-bed compartment. You can buy it at Austrian Railways website, oebb.at
