Old picture from August 1944 by Józef Jerzy Karpiński. Below the flight photo taken 1944.
The picture below is taken at the border of the Cargo area and the Deportation area pointing West. Jews of the ghetto had to march to the Umschlagplatz. The gate to the deportation area was close to the old shelter building seen on the left. In may cases peoples went directly to the trains. If the trains were not there or fully packed, the Jews had to sit and wait on the ground in the Umschlagplatz's courtyard or on the floor inside an empty school building on the site, where they waited, sometimes over night, for the new, empty train to pull in.
Empty trains from Treblinka arrived back to Umschlagplatz. Here, they were diverted along three (four) special rail spurs.
As the action on August 5, 1942 was rather well planned, I think that Orphanage children from the Little Ghetto went directly to the waiting cattle wagons to the right on the marked on the photo nr. 2 and 3. On right side of the top photograph one can see the end of the cattle wagon of type 1C with break cabin used by armed SS-soldiers.
58 normal cattle wagons (58 G ) and 2 cattle wagons with break cabins (1 C) of this type shown above were going on daily basis between Warszawa Ghetto and Treblinka (In German reports: Wagenzug bestehende aus 1C 58G 1C).
