What if I cross a country that isn't included in my pass?

If you cross a country that isn't included in your pass, you will have to pay an additional fee for that part of the route.

For instance, you can have a Eurail Select Pass valid in Italy and Spain, but not in France. In order to travel from Italy to Spain by train, you will have to go through France. In that case, you pay an additional fee from the Italian border to the Spanish border.
