The train staff of the delayed train or the Station staff should fix such problems as it´s a fault by them This is EU Law Which Trains (Trainnumber? Travelroute? which day? ) were delayed? To claim a case on the national passenger right office :)

Well, the problem is that there were different train companies in different countries . The train that caused the most delay was a Danish train, but we still managed to get Malmö, but there it appeared that all the trains to Stockholm were full until late afternoon (so, we're going to miss our connection there). But the Swedish staff said they couldn't do anything about Danish trains and they could only book us new seats for a later train to Stockholm (but we had to figure out the train for tomorrow to Härnösand ourselves, as that was a different company again). I got the feeling they especially didn't know what to do because we had Interrail tickets and booked most seats with the rail planner app. I heard someone tell people who had the same problem but had booked through DB that they had to contact them indeed, and that they could arrange accommodation, but we couldn't do that because we booked through Interrail, or something like that:').
