When buying an Interrail pass in Norway I have to bring my passport (or know my passport number). My problem is that I ordered a new passport very recently and will most likely receive it the day I leave or the day after. I will travel by plane to Prague and start taking trains from there. This means I won't have time to buy the Interrail pass in Norway.
Is it possible for me to buy the Interrail pass on the train station in Prague without my passport? All the countries I will visit are inside the Schengen Area and I can therefore travel around without bringing my passport. If my passport arrives the day after departure I can have someone pick it up and text me the passport number (and perhaps scan the passport and send me a picture that I can print and show on the train). Is it possible for me to travel around with only a regular ID card like my driver's license?
I could have gotten an emergency passport, but I hoped this should work out.
