We are travelling from London to Leipzig in a couple of months and have reserved seats on Eurostar and the night train from Brussels to Berlin.
In Leipzig we will be having some day trips, eg Eisenach, on local trains where reservations are not necessary or sometimes even possible. And we will want the flexibility in our return time.
I am not clear how we will use our passes. Do we just hop on a train and show our pass? Or do we need to activate the jourey once we are actually on the train?
