If you have been researching European rail passes, you have almost certainly encountered both "Interrail" and "Eurail" and wondered why they seem identical. The answer is simple: they are the same product, sold under different names depending on where you live. Which one you buy comes down to your passport and country of residence — not a difference in what you get.
The one rule that separates them
Interrail is for residents of Europe (and a handful of neighbouring countries such as Turkey and Morocco). Eurail is for everyone else — travellers from the US, Canada, Australia, the UK, Japan and most of the rest of the world. The trains you can board, the passes available and the prices are essentially the same. You simply cannot buy the "wrong" one: the booking systems check your nationality at checkout.
British travellers are a common point of confusion. Since the UK left the EU, some assume they now need Eurail. In fact, residency — not EU membership — determines eligibility, so UK residents still qualify for Interrail.
How the pass actually works
A rail pass gives you a set number of "travel days" to use within a validity window. On each travel day, you can board as many included trains as you like. The main variables to choose between are:
- Global pass vs One Country pass. The Global pass covers 33 countries and is what most people picture when they think of an Interrail trip. One Country passes cover a single nation and are worth considering if you are focusing on, say, France or Germany alone — though for France in particular, the point-to-point maths often favours buying individual tickets instead.
- Continuous vs Flexi. A continuous pass lets you travel every day within the window (7, 15, 22 days or a full month). A flexi pass gives you a fixed number of travel days — typically 4, 5, 7 or 15 — to use within a longer window of one or three months. Most multi-country trips suit a flexi pass unless you are genuinely on the move every single day.
- Age tiers. Both Interrail and Eurail offer Youth prices (under 28), Adult prices and Senior prices (60+), with significant discounts at either end.
What the pass covers — and what it doesn't
The pass gives you access to the rail networks of the participating countries, but it does not automatically get you a seat on every train. On many regional and intercity services — particularly in Germany, Austria, the Netherlands and Scandinavia — you simply board with your pass and that is that. No extra fee, no reservation needed.
However, on high-speed and overnight trains, you typically need to add a seat reservation. These come at an extra cost and are paid on top of the pass:
- French TGV services charge a reservation fee, and availability on the cheapest quota is limited.
- The Eurostar between London and Brussels or Paris requires a full Eurostar pass reservation, which carries a substantial supplement.
- Spanish AVE high-speed trains require reservations, and the supplements are not cheap.
- Italian Frecciarossa and Frecciargento trains require reservations.
- ÖBB Nightjet sleepers require a reservation for your chosen accommodation type.
On some routes, especially where pass holder quotas are small, reservations can sell out weeks ahead. This is the most important thing to understand before banking on a pass for a particular journey.
When a pass is worth the money
A pass pays off when you are making several long-distance journeys in a short time — particularly in countries where advance fares are hard to get (because you are booking late or the trains are heavily used). Germany and Austria are where passes tend to perform best: many trains need no reservation, and flexible intercity fares are expensive. A five-day flexi Global pass used for, say, a Munich–Vienna–Salzburg–Prague loop can easily beat the cost of individual tickets.
A pass tends to perform less well if most of your journey is in France, Spain or Italy, where reservation fees add up and cheap advance fares are readily available if you book a few weeks out. See the dedicated guide on when a pass beats point-to-point tickets for a full breakdown.
How to buy and how to use it
Both passes are now digital by default, stored in the Interrail or Eurail app on your phone. You activate a travel day in the app before your first departure of that day, and you can add reservations through the app or separately through national rail sites. Some travellers keep a screenshot of their pass in their camera roll as a backup — a sensible precaution.
Paper passes still exist but are increasingly rare. If you lose your digital pass, the apps have a recovery process, though it requires contacting support and takes time — so protect your login details.
Passes for under-28s
The Youth discount is substantial — often around 35% less than the adult price — making passes considerably more attractive if you are travelling before your 28th birthday. The age is checked at purchase; your pass remains valid for the duration of the booking even if you turn 28 during your trip.
Frequently asked questions
Can UK residents buy an Interrail pass after Brexit?
Yes. Eligibility is based on European residency, not EU membership. UK residents still qualify for Interrail and cannot buy a Eurail pass.
Is the Eurail pass accepted on Eurostar?
Yes, but a Eurostar-specific reservation must be added on top, and it carries a significant supplement. Availability for pass holders is limited, so book early if Eurostar is part of your plan.
Do I need to validate my pass before boarding?
With the digital pass, you must activate a travel day in the app before you travel. Some countries require you to show a ticket inspector your activated pass; the app generates a pass "view" designed for this. Always activate before you board, not after.
What countries are included in the Global pass?
33 countries participate, including all major Western European rail networks. The exact list is on the Interrail and Eurail websites; confirm before you buy if a specific country is central to your trip, as the list does occasionally change.
