Learn how to travel from A to B

On some Interrail routes you need a seat reservation. The same applies to night trains. There is often an option to avoid trains that require reservations. It may look tiring at first, but once you’ve read through the following examples, the fog will lift.

Here’s how I recommend you check a route:

  1. Search for a train connection in a timetable tool.
    You can do this in the Interrail app, for example. It will show you whether there is a train that requires a reservation on your desired connection.
    The Deutsche Bahn timetable information in combination with the information on train types on is also good. However, a little experience is useful here.
  2. If you see trains that require reservations, you can use the Deutsche Bahn tool to try to create a different route. Search for stages – not the entire route. By deselecting train types and adding detours.
  3. Buy seat reservations: many reservations can be bought directly in the Interrail app. Or follow the instructions on, as the railway companies often sell reservations directly.

Important: don’t despair. There are always options you might not see at first glance, but that’s what I’m here for. Let’s now go through a few examples.

What is the Interrail Ticket ?

Interrail is a rail pass that allows you to travel in 33 European countries. One ticket for all countries. Simple and flexible.

Interrail is available in different versions: for a short trip through the capitals of Europe. Or for a month-long trip from north to south and east to west. You can find all ticket variants on this overview page.

Please note:

  • Some trains require an extra seat reservation. These are usually high-speed trains. However, this can often be avoided. Fred will explain how this works.
  • On a night train, you have to reserve your sleeping place or seat, but in return you save the night in a hostel or hotel.
  • Interrail is not valid in your country of residence. However, you have one free exit (outbound) and one free entry (inbound). For transit, you can use the savings fares of the railway companies, for example.
