Everytime I try planning something interrail based, I get infuriated by the poor design choices made by every rail journey planner out there. As well as the inherent flaw in every journey planner: it assumes I know where I want to go. Sometimes I just want to say "I'll be arriving in $station at $time. Where can I go by train in the next 2 hours?" Or "where can I get to from this station?" The aimless rambling is hard. It's something I miss about paper time tables.
