Eurail sells rail passes that let travelers hop between European countries on many national and private train services without buying separate point-to-point tickets. The site focuses on multi-country and single-country passes, including the Eurail Global Pass that covers up to 33 European countries, plus regional and specialty options (youth, senior and first/second class). Passes can be purchased as mobile e‑passes through the Eurail website and app, or as physical documents where available, and the platform includes route planning tools and information on seat reservations and supplements.

Eurail is built around flexibility: passes are valid for a set number of travel days within a chosen validity window, which suits itineraries that change on the fly. That flexibility comes with trade-offs — some high-speed and night trains require mandatory seat reservations and reservation fees, and certain private operators or regional services may not be fully covered. Eurail distinguishes itself from Interrail (the similar product for European residents): Eurail is intended primarily for non-European residents planning cross-border rail travel, and the website highlights both trip-planning resources and add-ons like rail passes for families, youth discounts, and multi-class seating options.
