Railway worker armbands
These armbands were worn by Jewish railway workers who unloaded the trains that arrived at Auschwitz and Raisko Concentration Camps. New Jewish prisoners were more likely to remain calm if they were directed by other Jews. Jewish railway police needed to show the Nazis that they would carry out their orders or they themselves would be replaced.
One armband is from Raisko, a labor sub-camp of Auschwitz. Bahnpolizei means railway police.
