Can I avoid trains with reservations?

You may want to keep the costs of your trip down by avoiding trains that need to be reserved. Or you might find that the train you want to reserve has no seats left for pass holders, which means you’ll need to find an alternative train or route to make your journey.

You can use the Interrail timetable to look up alternative ways to make your journey. Do keep in mind that there aren’t always alternative options available, but it’s worth checking.
