Making seat reservations for German trains
It's possible to make reservations for German high-speed and night trains on the Deutsche Bahn website and then print them out. You can make reservations up to 3 months in advance.
You'll need a reservation for sleeping accommodation on most night trains. Reservations are optional for ICE trains, but during peak season (May - September) and public holidays, we recommend making a reservation in order to guarantee yourself a seat.
Please keep in mind that it's not possible to make online reservations for international day trains to and from Germany. For those reservations we advise you to contact the Deutsche Bahn call center (+49 180 699 6633) or go to an international ticket office at larger German train stations.
