I am planning to finish a trip and go back to Switzerland using the Nightjet train from Germany.
If I use an Interrail Global pass, I am confused by two overlapping rules that apply:
When taking a night train, only the departure day (day 1) must be marked as a travel day; it is not required to "consume" the next day (day 2) if there is no change of trains after midnight
The pass allows one outbound day and one inbound day to travel out and back into the country of residence (Switzerland). Those days must be marked on the pass.
The border crossing is in the morning of day 2 at Basel, and I plan to remain on board until it reaches Zurich.
In this situation, which day has to be counted as the inbound travel day? Day 1 or day 2?
