Check the departures board at the train station to see on which track your train will be arriving.
Record each date of travel in ink on the back of your pass in the travel calendar. before you board the train for that date of travel. This step is only required if you purchased a Flexi Pass.
Board the train. If you purchased a reservation, you will have been given a seat number. If you have any trouble finding your seat, see a conductor. If you did not purchase a reservation, sit in any seat that is free and does not have a slip of paper next to the seat number listing a destination. If there is a slip of paper, that seat has been reserved.
Keep your ticket and identification ready. When the conductor arrives, hand over both for inspection.
Listen carefully to the upcoming stops and exit the train at your destination.
