Are you planning train travel in Europe and are wondering exactly how Interrail works?
This is where I can help. I’m a massive fan of rail travel and have Interrailed as a backpacker in my 20s and as a mature solo traveller in my 50s, using both the old-fashioned paper train pass and the shiny digital pass.
Whether you are travelling for one week or two months, this guide will tell you everything that you need to know about these Europe rail passes and help you decide if Interrail is worth it for you.

What is an Interrail Pass?
There is no such thing as one definitive Interrail pass. Interrail offers a range of passes giving European residents unlimited travel on scheduled train services of participating train operators across Europe.
If you are a non-European citizen, you can use a Eurail pass instead. This offers identical benefits to Interrail.
Interrail passes are available for children, youths, adults & seniors. They offer first or second-class train travel in all participating countries or country-specific passes.
As well as free unlimited train travel, Interrail passes come with a host of other benefits. These include free or discounted rides on many ferries, including those serving the Greek islands and Ireland.
Types of Interrail Pass
There are two types of Interrail passes: the Global Pass and the One Country Pass.
Interrail Global Pass
Interrail’s flagship product, the Interrail Global Pass, gives you the joy of train travel in 33 European countries as well as on some ferries. This product includes unlimited travel on local trains, high-speed trains and night trains over a specified period of time, forgoing the need to buy point-to-point tickets.
The Interrail Global Pass is a great option for stress-free and flexible country-hopping in Europe. It comes in ten different variations:
Flexible
- 4 days within one month
- 5 days within one month
- 7 days within one month
- 10 days within two months
- 15 days within two months
Continuous
- 15 days continuous
- 22 days continuous
- 1 month continuous
- 2 months continuous
- 3 months continuous
As the name suggests, you use a continuous pass on consecutive days. For example, if you buy a one-month continuous pass, it remains valid for one month after the date it is first used, allowing you unlimited travel within that period.
With a flexible pass, you can travel a set number of days within a specified period. For example, if you buy a 5-day in one-month flexible pass, you’ll be able to travel on five days of your choice within one month.
The Interrail Global Pass gives you the freedom to explore the following countries: Austria, Belgium, Bosnia-Herzegovina, Bulgaria, Croatia, Czech Republic, Denmark, Finland, France, Germany, Great Britain, Greece, Hungary, Ireland, Italy, Kosovo, Lithuania, Luxembourg, Macedonia, Montenegro, Netherlands, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland and Turkey.
Interrail One Country Pass
But what if you are planning an in-depth visit to just one country? Visiting the vineyards of France, perhaps? Or exploring Switzerland’s Alpine valleys? In most cases, an Interrail One Country Pass is your best bet.
30 European countries have their own Interrail pass valid for unlimited travel within that country’s borders. These countries are as follows: Austria, Bulgaria, Croatia, Czech Republic, Denmark, Estonia, Finland, France, Germany, Great Britain, Greece, Hungary, Ireland, Italy, Latvia, Lithuania, North Macedonia, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland and Turkey.
In addition, you can also purchase a regional pass for the Benelux countries (Netherlands, Belgium and Luxembourg).
New for 2026! Interrail Plus Pass
Currently testing in a Beta Version, the Interrail Plus Pass includes seat reservation costs for high-speed and popular routes. This is something I welcome, as it’s easy to underestimate these additional costs if you are travelling in countries where these are required, such as France, Italy, Spain and Germany.
As of December 2025, these are available for Global Passes (5 or 7 days within 1 month ), Italy (4 days within 1 month) and Germany (4 days within 1 month). They need to be activated within three months of purchase.
As ever, the devil will be in the detail, but the cost of the plus version of the popular seven-day Global Pass is only marginally more than the regular pass.
How Much Does an Interrail Pass Cost?
The price of an Interrail pass depends on the following:
– Country or countries of travel
– Class of travel (1st or 2nd Class)
– Duration of travel
As a benchmark, the adult Interrail Global Pass starts at £252 for four days of 2nd-class travel within a month (December 2025 price). Prices of country-specific Interrail rail passes depend on the country of travel.
Discounts are available for children and those under the age of 27, and for seniors (60+ years) in both first and second class.
I’ve saved money on passes in the past with flash sales.
How to Buy an Interrail Pass
You can buy an Interrail pass up to 11 months before your first intended travel date here. When you place your order, choose to receive a classic printed ticket or a mobile pass, which sits in an app on your phone.
Paper passes are typically delivered in 10 days using tracked delivery (this cost is included in the total purchase price).
With the Interrail mobile pass, it’s free instant delivery (a good option if you’ve left it until the last minute to buy your Europe rail pass). You add the pass to the Rail Planner app and activate it when you are ready to travel.
This mobile option is not available for some One Country passes.
I’ve used both paper and mobile Interrail passes and prefer the latter, but here are a few things to consider:
| Advantages of a paper pass | Advantages of a mobile pass |
|---|---|
| A paper rail pass does not rely on mobile phone battery power | Instant delivery |
| A paper rail pass does not rely on a broken mobile phone | No delivery cost |
| Your paper Interrail pass is a great travel record to treasure | As the pass is on your phone, you will always have it with you, and it’s one less thing to carry around (and lose) |
| If your paper Interrail pass is lost or stolen, it can’t be replaced If you lose the device on which your mobile Europe train pass is loaded, your pass can be loaded on a new device free of charge. | |
| If your paper Interrail pass is lost or stolen, it can’t be replaced. If you lose the device on which your mobile Europe train pass is loaded, your pass can be loaded on a new device free of charge. |
Using your Interrail pass
An Interrail pass gives you free travel on all the train services run by the national train operator in each of the countries it covers. Trains run by private operators are not covered by these European rail passes.
Most of the time, you will not need to buy a ticket ahead of time; you can simply board the train, pass in hand. However, you will need to make a reservation and/or pay a supplement on some trains.
More about that later.
How you use your Interrail pass will depend on whether you have opted for a paper ticket or a mobile pass. Each of these types of rail passes becomes valid the first time you use it.
Using the Interrail paper ticket
The classic Interrail pass comprises a cover printed with a blank travel diary (or ‘My Trip’), to which your train pass is attached.
Each time you take a train, you need to:
- Record the date and journey in the travel diary. If you wish, you can choose to record your journeys in the Rail Planner app
- If you have a flexible Interrail pass, enter the travel date into the travel calendar on the pass itself.
If you are using your Interrail pass in your country of residence, you will also need to record the inbound/outbound date in the travel diary and on your ticket, if you are holding a Flexi pass.
Make sure that you record these data before boarding your next train. If you don’t and are unlucky to get a jobsworth conductor, you risk a fine and being forced to pay for a full-fare ticket.
Using the Interrail mobile pass
There is a comprehensive guide to using the mobile Interrail pass, but here’s a short version.
Step 1: Download the Rail Planner app to your phone
Step 2: Add your mobile Euro rail pass to the app
Step 3: Connect a trip to your Interrail pass and give it a name (for example, ‘My Switzerland Trip’). This is how you keep track of the journeys you take.
Step 4: Activate your Pass
Before you start your trip, you need to activate your Pass. You do this by:
- Entering your passport or ID number. This should match the document that you’re travelling with, as you may have to show it to ticket inspectors.
- Choosing the first day you’ll use your Pass to travel
Step 5: Save your journey to My Trip
Step 6: Add your journey to your Pass
When you are ready to travel, go to your trip and tap to add your journey to your Interrail pass.
Step 7: Show your ticket to the conductor
Although this may seem complicated at first, it is not.
Interrail Seat Reservations
Most of the time, you can hop on trains spontaneously, sit where you like and just show your pass to the conductor when he or she comes around. However, some railway companies have a compulsory seat reservation, subject to a fee.
This reservation fee is not included in your Interrail pass. The cost depends on the type of train, the type of seat and the railway company.
Train services that require a reservation include:
- High-speed trains in Western Europe
- Night trains (the Caledonian Sleeper, for example)
- Scenic trains (the Glacier Express, for example)
- Eurostar trains
To avoid reservation fees, you can choose to travel on regional services. Although these train services don’t require seat reservations, they are slower. On the plus side, slower travel allows you to discover places you may never have found when travelling on a high-speed service.
Using the Rail Planner app, you can select the ‘no reservation needed’ filter to exclude services with compulsory reservations. Selecting the ‘no seat reservations required’ filter in the Interrail trip planning engine will do the same job.
Even when it is optional, it can be a smart move to make a seat reservation, especially for popular services, long journeys and busy times.
Making Interrail reservations at a railway station
Interrail reservations can be made at most station ticket offices. As train reservation systems are linked across most of Western Europe, you can make reservations for trains departing from a station other than the one you are at.
A booking fee may be charged when making a reservation in some countries.
Making Interrail reservations online
This is where it gets slightly complicated. There is no magic bullet here; i.e. no single website that will make all of your Interrail reservations at no additional cost.
Only a handful of national train operators will make reservations for Interrail pass holders. Alternatively, you can make a reservation via Interrail, but this is the most expensive way of doing it.
Making a reservation through Interrail
Interrail claims it can handle seat reservations for 95% of all European trains. These are made by logging into your Interrail account and going to ‘My Trips and Travellers’ on the top menu bar (under ‘Hi *yourname*’).
Seat reservations are sent as e-tickets or old-fashioned paper tickets.
You can also make reservations via the Rail Planner App.
Making a reservation through the rail operator
Alternatively, you can make reservations online with the national train operators, including Austrian railways and DB (Germany).
Making Interrail reservations over the phone
As a last resort, you can make European train travel reservations over the phone. This is complicated and can attract additional fees.
Other Useful Information
Can you use an Interrail Pass on city transport?
You can rarely use an Interrail pass on urban transport systems.
Most public transport (metro systems, buses, trams and the like) is operated by urban transit authorities, not train companies. However, a handful of cities let you use your Interrail pass on their public transport; check the additional benefits for your country of interest.
For example, you can use your Interrail pass on the S-Bahn (suburban metro railways) networks that DB operate in major German cities.
In a country as expensive as Switzerland, being able to use your European rail pass to get free or discounted travel on boat trips and private railways can save you a ton of money. For example, I have bagged an Interrail discount on the cable car journey between Grindelwald and First.
Bear in mind that if you are using a flexible Interrail pass, this may not be a cost-effective way of using up one of your days. Of course, this is not an issue with continuous passes.
Using an Interrail Pass in your own country
Interrail passes do not cover unlimited train travel in your country of residence. However, you can use a Global Interrail Pass for two domestic journeys: one at the beginning of your trip from your home station to a border, airport or ferry port and a second journey at the end of your trip.
Although this domestic journey must be a continuous single journey between a point of origin (for example, your home station) and a border, airport or ferry port, it can involve more than one train.
Note that this will use up a travel day on your pass. But as one travel day lasts from midnight to midnight, you can use as many trains as you like within that time period.
You can make this work for you.
On different Interrail trips, I have used this allowance to cover the train journey from my home station to Central London, a Eurostar pass journey to Paris, and onward trains to Bern, Switzerland and Cologne, Germany and the champagne houses of Reims in France
Is a 1st-class Interrail Pass worth it?
There are several reasons why you should consider a 1st-class Interrail pass (I’m a big fan).
All that said, second-class seating is perfectly adequate on European trains, and not all countries have first-class carriages on their train services.
