@ad951bfd the DB oracle spits out high demand expected (you most likely know that already), but recently this has been wrong quite often. Also the IC to Düsseldorf 16:50 only has high demand until Osnabrück/Münster so at least there might be a seat available for the last two hours. 
🤞 Hope it turns out well. 

 @8d0e3c19 i have another satapoint to confirm this actually! I made the 2nd train and there are *plenty* of spare seats...
