Reservations are compulsory on some international services. If so, the reservation will already be included free of charge in the ticket price. Reservations are required in the following trains:

• France: high-speed trains (ICE and TGV) to Paris and Marseille (including all stopovers)
• Italy: Trains to Milan via Basel Bad Bf
• Poland: All long distance trains to Poland

Please note that you cannot travel on trains requiring reservations without a reservation, even if you have already purchased a flexible fare ticket including a reservation for another train.
