Do I need a reservation or a surcharge when travelling with my Eurail Pass?
You need a reservation for many European high-speed trains and for all night trains. This means that you cannot travel by train without a reservation.
Please also note that a reservation including surcharge is required for high-speed trains between Germany and France and for Eurocity trains between Munich and destinations in Italy.
You can make your reservation for almost all European trains up to 6 months before departure online here, at DB points of sale and at www.eurail.com, for some trains up to 3 months before departure.
Reservation costs are not included in the Interrail Pass.
