Do I need a Eurail or an Interrail Pass?
A Eurail Pass can only be used by non-European citizens or non-European residents. European citizens can use an Interrail Pass instead, available from Interrail.eu. If you are not a European citizen, but you are a permanent resident of Europe, you can also choose to use an Interrail Pass.
In some cases, you can be eligible to use either Eurail or Interrail. Please make sure you always choose the option that matches the travel document you will take on your trip. For example, Australian citizen who are permanent residents of Spain can travel with a Eurail Pass. However, they should then make sure to fill in their Australian passport number when purchasing a Eurail Pass.
