I want to take the EN40459 from Zurich to Prague. However, the entire route only has sleeper cabins or seats, and I would like to sleep in a couchette car due to budget reason.
I have noticed that the train is actually coupled together with NJ409 and EC459 from Zurich (19:59) until Leipzig Hbf (04:49), and NJ409 offers couchettes. (After Leipzig Hbf, NJ409 continues to Berlin while EC459 goes to Prague)
Is it allowed to reserve a couchette in NJ409 to Leipzig Hbf, then get off the train and go to another carriage of what is technically the same train in the EC459 portion, without activating another travel day?
Alternatively, could I reserve a seat on the EC459 from Zurich (19:59) to Prague (09:15), which technically begun on an activated travel day, but not get on the train until Leipzig Hbf (04:49), which is on the next day, without activating that day? Could I do the same without reserving a seat?
