Bag and ID Lost Valencia, Valencia, Spain

I have lost a black backpack of Dakine in station of Rzepin end of May 24. It is Dakine Heli Pro version. Inside were passport, many memory sticks and documents and other things.

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.

A brown bag with a wallet and Keys inside my id card is in the wallet with my full name on it. My first and last name are destiny Strijdhaftig.
