Hi, has anyone had experience booking this journey? I have been trying to get reservations only as I have an interrail ticket but interrail were unable to book. I had a look at going direct with Obb however they did not allocate reservations for Prague to Linz, but they did for Linz to Salzburg (the last part of the journey). Just hoping someone else had been in this route and has experience. Ps. Travelling with kids hence wanting set reservations.
