The scale of the Final Solution would not have been possible without the Reichsbahn.
The extermination of Polish and foreign Jews depended on the railways as much as on the secluded killing centres.
The Holocaust trains sped up the scale and duration over which the extermination took place; and, the enclosed nature of freight cars also reduced the number of troops required to guard them.
Rail shipments allowed the Nazi Germans to build and operate bigger and more efficient death camps and, at the same time, openly lie to the world – and to their victims – about a "resettlement" program.
In one telephone conversation Heinrich Himmler informed Martin Bormann about the Jews already exterminated in Poland, to which Bormann screamed in response: "They were not exterminated, only evacuated, evacuated, evacuated!"

Unspecified number of deportees died in transit during Operation Reinhard from suffocation and thirst.
No food or water was supplied.
The Güterwagen boxcars were only fitted with a bucket latrine.
A small barred window provided little ventilation, which oftentimes resulted in multiple deaths.
A survivor of the Treblinka uprising testified about one such train, from Biała Podlaska.
When the sealed doors flew open, 90 percent of about 6,000 Jewish prisoners were found to have suffocated to death.
Their bodies were thrown into smouldering mass grave at the "Lazaret".
Millions of people were transported in similar trainsets to the extermination camps under the direction of the German Ministry of Transport, and tracked by an IBM subsidiary, until the official date of closing of the Auschwitz-Birkenau complex in December 1944.

Death factories were just one of a number of ways of mass extermination.
There were secluded killing sites set up further east.
At Bronna Góra (the Bronna Mount, now Belarus) 50,000 Jews died in execution pits; delivered by the Holocaust trains from the ghettos in Brześć, Bereza, Janów Poleski, Kobryń, Horodec (pl), Antopol and other locations along the western border of Reichskommissariat Ostland.
Explosives were used to speed up the digging process.
At the Sosenki Forest on the outskirts of Równe in prewar Wołyń Voivodeship, over 23,000 Jews were shot, men, women, and children.
At the Górka Połonka forest (see map) 25,000 Jews forced to disrobe and lay over the bodies of others were shot in waves; most of them were deported there via the Łuck Ghetto.
The execution site for the Lwów Ghetto inmates was arranged near Janowska, with 35,000–40,000 Jewish victims killed and buried at the Piaski ravine.

While the Order Police performed liquidations of the Jewish ghettos in occupied Poland, loading prisoners into railcars and shooting those unable to move or attempting to flee, the collaborationist auxiliary police were used as a means of inflicting terror upon the Jewish people by conducting large-scale massacres in the same locations.
They were deployed in all major killing sites of Operation Reinhard (terror was a primary aim of their SS training).
The Ukrainian Trawniki men formed into units took an active role in the extermination of Jews at Belzec, Sobibór, Treblinka II; during the Warsaw Ghetto Uprising (on three occasions, see Stroop Report), Częstochowa, Lublin, Lwów, Radom, Kraków, Białystok (twice), Majdanek, Auschwitz, the Trawniki concentration camp itself, and the remaining subcamps of KL Lublin/Majdanek camp complex including Poniatowa, Budzyń, Kraśnik, Puławy, Lipowa, and also during massacres in Łomazy, Międzyrzec, Łuków, Radzyń, Parczew, Końskowola, Komarówka and all other locations, augmented by members of the SS, SD, Kripo, as well as the reserve police battalions from Orpo (each, responsible for annihilation of thousands of Jews).
Mass executions of Jews (as in Szebnie) was part of regular training of the Ukrainian Waffen-SS Division soldiers from the SS-Heidelager troop-training base in Pustków in south-eastern Poland.
In the north-east, the "Poachers' Brigade" of Oskar Dirlewanger trained Belarusian Home Guard in murder expeditions with the help of Belarusian Auxiliary Police.
