The SS used a variety of ruses to move thousands of new arrivals travelling in Holocaust trains to the disguised killing sites without panic. Mass deportations were called "resettlement actions"; they were organised by special Commissioners and conducted by uniformed police battalions from Orpo and Schupo in an atmosphere of terror. Usually, the deception was absolute; in August 1942, people of the Warsaw Ghetto lined up for several days to be "deported" to obtain bread allocated for travel. Jews unable to move or attempting to flee were shot on the spot. Even though death in the cattle cars from suffocation and thirst was rampant, affecting up to 20 percent of trainloads, most victims were willing to believe that the German intentions were different. Once alighted, the prisoners were ordered to leave their luggage behind and march directly to the "cleaning area" where they were asked to hand over their valuables for "safekeeping". Common tricks included the presence of a railway station with awaiting "medical personnel" and signs directing people to disinfection facilities. Treblinka also had a booking office with boards naming the connections for other camps further east.
