A rail pass is a travel document that entitles you to travel on European trains in a specific geographic area (country/countries) for a specific number of days.

The number of days during which you can take the train with your rail pass are typically referred to as Travel Days, while the period within which you can use your travel days is referred to as the rail pass validity period. A travel day lasts from midnight to midnight. During this period, you can take as many train trips as you want within your rail pass area of coverage.

What about overnight trains? To be fair, even if your train departs in the evening one day and arrives at its destination the next, in most cases it will count as one rail day and not two. The rule is that you must board a train that departs after 7:00pm and arrive at your destination after 4:00am without changing trains. On the other hand, if your train departs before 7:00pm, or involves a connection, you will need to use two days of your rail pass. This policy is sometimes referred to as 'the 7:00pm rule'.

Last but not least, it's very important to understand reservations when traveling with a rail pass. We have a whole section devoted to reservations, but in short, be aware that having a rail pass doesn't necessarily mean that you can hop on any train at will, within the geographical area covered by your rail pass. Depending on the country, the type of train and the route, you may need to purchase seat reservations at an additional cost. It does take away a bit of the flexibility offered by rail passes, but this is the policy that certain rail carriers have put in place, especially for high speed trains and night trains. Make sure to read our section on Seat Reservations for complete information.

This is a requirement that's defined by each individual European railroad, and which varies from one train to another. However, there are essentially three types of trains in Europe: trains that are 'reservation required', trains that are 'reservation recommended' (but optional), and trains that are 'non-reservable'.

So while rail passes offer rail travel by country all over Europe, they can't account for the mix of reservation requirements on your specific trip. As a result, you'll still need to buy a reservation for 'reservation required' trains. Requirements vary, so we encourage you to read our detailed article on Seat Reservations to understand when you may need to purchase one.

A rail pass and a train ticket are two completely different types of travel documents.

A train ticket is valid for a single journey between two cities. Many tickets also include a reservation, which mean that they are valid only for a specific train, on a specific date and at a given time. To learn more about tickets, read the section Train Tickets Explained.

A rail pass, on the other hand, is good for travel in an entire geographical area (1 country, 2 countries or more). With it you can take as many train trips as you want within that geographical area, for as many travel days as you bought, within a set period of time (the pass validity period).

For any given itinerary in Europe, you can generally choose between both: train tickets or a rail pass, and individual reservations as needed. In general, traveling with a rail pass is more cost-effective when taking three trips or more, but it really depends. Make sure to do your research in advance to determine whether a pass is most cost-effective for your itinerary.

A flexi pass is valid for a specific number of travel days to be used within the overall validity period of that rail pass. For example, 15 days of unlimited train travel to be used within a 2-month period. With this kind of rail pass, you can pick and choose any days (they don't have to be consecutive) to travel within the rail pass' validity period.

Consecutive rail passes such as the Eurail Global Pass, are valid for unlimited train travel during the whole duration of the pass' validity period. In other words, with a 15-day Eurail Global Pass, you can travel for 15 consecutive days by train. Even if you don't take the train each and every day, those days will count as used.

A rail pass travel day is a 24 hour period, from midnight to midnight, during which you can take as many train trips as you want. Since rail passes use calendar days, trips within 24 hours of each other but on different days will count as two travel days.

The only exception to this rule concerns overnight train trips. Overnight train trips departing after 7:00pm and arriving after 4:00am without any change of train will count as one travel day, and the arrival date should be recorded on your rail pass. But overnight train trips departing after 7:00pm that arrive or involve a connection between midnight to 4:00am count as two travel days.

The validity period of a rail pass is the time period within which you must complete your travel with your rail pass. This period is calculated from the date stamped on the rail pass by the rail official.

With a flexi pass this period is defined as a certain number of calendar months - usually two. For instance, if you are traveling with a 5 day Eurail Italy Pass and your rail pass is first stamped on July 1, you must use your 5th travel day no later than midnight of August 31.

With a continuous day pass the validity period equals the number of travel days. For example, if you're traveling with a 1 month Eurail Global Pass first stamped July 1, you can't use it to travel past midnight on July 31.

In general, yes, but there are some exceptions and a few rules to keep in mind.

First, be mindful that some trains (such as many high-speed and night trains) require travelers with a rail pass to purchase reservations at an additional cost. Make sure to read our detailed article on Seat Reservations.

If you take an international train, make sure that your rail pass covers not only the country of origin and country of destination, but the countries through which your train will travel. For instance, if you're taking a train from Munich to Venice, it's obvious your rail pass needs to cover Germany and Italy. But trains connecting these two cities also travel through Austria, so your rail pass will also need to cover Austria as well.

Lastly, some private rail lines in certain countries don't offer reservations for rail pass holders and don't accept rail passes, requiring you to locally purchase a stand-alone regular ticket. When you book your rail pass, you will receive a map and travelers guide that shows its full coverage. This is especially relevant for travelers with a Swiss Pass or Eurail Pass that includes Switzerland, since Switzerland has many of those private rail lines. Germany, France, and the UK also have a few private rail lines not included with our rail passes.

No. You can take as many train trips as you want within one day and only use one day, as long as your last train ride ends before 11:59pm.

The travel bonuses that come with your pass must be redeemed locally.

There are two types of bonuses. 'Free' bonuses (such as a free airport transfer) require the use of a travel day on your pass. If you've already used up all your travel days, you can't take advantage of the 'free' bonuses anymore. 'Discount' bonuses do not require you to use a travel day, but do require that your pass still be within its validity period. In other words, even if you've used up all your days on a pass, you can still claim 'discounted' bonuses as long as the pass' validity period has not lapsed.

The exception to this rule is the Swiss Passes. Although a 'discounted' bonus doesn't require you to use a travel day on your Swiss Pass, the pass must still be valid and you must not have used up all your travel days to redeem such 'discounted' bonuses.
