Lost bag Lost Aachen, North Rhine-Westphalia, Germany

Property description

On sunday 16.03.2025 I was traveling from aachen to aachen west via RB 33 (10320) at 10.37 am. As I was travelling to belgium i did carry my passport as well. On the way I forgot to take my bag [bagpack] and lost it in the RB . Bag is blue color ,inside i have my laptop , my purse which have my all id cards [ rp card, insurance card ,bank card], my passport ,and few other things. I tried to catch the train at duisburg as it was showing as duisburg as last stop , but in midway at krefeld the train got stopped and when i reached their there is no train and I missed it. I raised a complain in db lost and found as well. I have checked with both aachen as well duisburg info and there seems no details on the item. As it does contain my passport it will be so helpfull if you can really provide a detail on what i should do further and when and where i really can expect it.
