Hello Flyertalk train mavens,

I'm trying to book a first class ticket from Prague to Berlin on Dec 26, and am flexible on time.

The system errors with:

Connection not found.
Possible reasons:
the connections does not run in the particular time period,
no direct connection or connection with 1 change is available between starting and destination object,
the connection by allowed means of transport is not available,
possible operational restrictions on the route of connection without ensuring alternative transport - more information about operational restrictions.

Does this mean they are simply out of first class on all trains, or is there a trick I'm missing?
