Many trains offer you a choice of seat types. For day trains, your choice of seating depends on the extra facilities and amount of legroom. For night trains, your choice ranges from a reclining airline-type seat to a private cabin with a comfy bed.

Yes, you can sleep on Eurail by booking a journey on a Night Train (such as ÖBB Nightjet or EuroNight). When using a Eurail Pass, you have several sleeping options: Seats (the cheapest but least comfortable), Couchettes (shared compartments with 4–6 padded bunks and basic bedding), and Sleeper Cabins (the most private option with 1–3 proper beds, often including a sink or even a private shower). It is important to note that a Eurail Pass covers the basic "transport" cost, but you must pay a separate reservation fee for a couchette or sleeper bed. In 2026, night trains are undergoing a massive revival in Europe as a sustainable alternative to flying, allowing you to go to bed in a city like Vienna and wake up in Paris, saving you the cost of a hotel night while maximizing your travel time.
