Why do I have to pay for seat reservations when I already have a Eurail Pass?
Your Eurail Pass gives you access to trains run by the participating railway companies. For most high-speed and all night trains, the railway companies charge optional or compulsory reservation fees. This guarantees you a seat on popular or faster routes, which may become crowded during busy periods.
As a pass holder you only need to pay the reservation fee, not the full fare ticket. Please note that the reservation fees can differ depending on the country and type of train. We have an overview of the reservation fees.
