In the updates for Rick Steves' guidebooks, it says:
Connections
A Prague–Vienna sleeper car (not a couchette), not mentioned in the book (or on Deutsche Bahn online schedules), leaves the Hl.N. station at 23:10 and arrives at Vienna Westbahnhof the next morning at 6:30. Coming from Vienna, that train leaves the Westbahnhof each night at 22:08 and arrives in Prague at about 6:15
However, when I checked this out on the bahn.de website, it looks like the 22:08 train from the Westbahnhof gets in at 3:22 am, not 6:15 am. There is another 22:08 train that leaves from Südbahnhof Ostbahn, but it changes in Bratislava.
Does anyone know anything about the train described in the update?
