Planning an interrail trip and was just wondering whether you literally can just hop on and off trains as easily as it sounds. As in, you get on a train and (excluding supplements, reservations etc) your pass is the equivalent of a regular ticket.
Or do you still require a ticket or similar to be got at the station and the only difference is that you're not paying?
Did some travelling by rail in the US and there I had my entire journey validated at the first station for the rest of the month i spent there. Of course that was different as was a very fixed schedule and knew exactly what train at what time and what day I was getting etc.
So just wondered if it was similar in this case, hope that all makes sense!
