Can you buy the Eurail pass in Europe?
Yes, it is possible to order the Eurail pass after you have arrived in Europe. Please note that this is often more expensive than ordering online in advance. It is also an option to have the passes delivered to your (first) hotel in Europe.
Please note that seat reservations are required for most trains in Europe. The costs for these reservations are not included with the train pass.
You can book all reservations in advance via HappyRail (on condition that you buy your Eurail pass via HappyRail).
