Question

how does a ticket work?

Hi, I understand that the pass is the ticket but I do not understand how the pass knows if there is still space on the train. For example, I want to travel from Annecy to Munich. I will have to stop off in Annemasse, Geneva and Zurich. Some of these journeys say "booking recommended". So the booking is not obligatory. But what if I confirm the entire trip, get to Zurich and want to create the ticket for the Zurich - Munich stretch and the app tells me " sorry there is no more space on this train" ? Even on trains that do not require any booking. I guess that if the train is full, the ticket machine or person does not sell you a ticket...? So is that not the same for interrail? Or does the app kind of create a seat for me when I confirm the trip? Even if I have not paid for a seat? I have not taken many trains before 😅

It rarely happens that a train is so full, that they won’t let you board and it’s even less likely, they won’t sell you a ticket.
It could happen that you have to move around, because seats are taken, but not always between the same stations or you even have to sit on the floor. But I wouldn’t worry too much beforehand.

When reservations are optional, a train cannot sell out. Tickets are always available.

In addition, the pass does not know anything about seat availability. You can add any train to the pass and generate a ticket for it. It cannot and does not "create a seat”.

As noted above, the app will not give that information if reservations aren’t required, so if you are concerned about not finding a seat on the Zurich-Munich journey you can check the DB or SBB apps to see their forecast on expected demand for your class.
