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.
