When I tried to buy a train ticket, it says "seat reservation: only, no ticket or pass included - BUT REQUIRED". What is that suppose to mean? Do i have to buy a pass in order to travel using train although im planning to buy one way ticket?anyone can explain to me what Eurail o Interail pass means?

Thank You

Hi.
Which train connection, time and date ?
As Raildude is specialized on Rail Pass travellers, we sometimes can not over "normal reservations". Often a reservations is already included in a point to point ticket.

Interrail is for persons with country of residence in Europe: http://www.raildude.com/en/interrail-first-time

Eurail for non-Europeans: http://www.raildude.com/en/eurail-first-time

Both are rail passes, worth if you travel several routes within Europe, especially worth for long-distance connections.
