The [[Grossaktion Warsaw (1942)|mass deportation]] of Jews from the Warsaw Ghetto began on 22 July 1942 with the first transportation of 6,000 people. The gas chambers began to be operated the following morning.{{sfn|Kopówka|Rytel-Andrianik|2011|p=94}} For the next two months, deportations from Warsaw continued daily, via two shuttle trains (the second one, from 6 August 1942),{{sfn|Kopówka|Rytel-Andrianik|2011|p=92}} each carrying about 4,000 to 7,000 people crying for water. No other trains were allowed to stop at the Treblinka station.{{sfn|Kopówka|Rytel-Andrianik|2011|p=98}} The first daily trains came in the early morning, often after an overnight wait, and the second, in mid-afternoon.{{sfn|Kopówka|Rytel-Andrianik|2011|p=94}} All new arrivals were sent immediately to the undressing area by the ''Bahnhofskommando'' squad that managed the arrival platform, and from there to the gas chambers. According to German records, including the [[Stroop Report|official report]] by SS-''[[Brigadeführer]]'' [[Jürgen Stroop]], 265,000 Jews were transported in [[freight train]]s from the Warsaw Ghetto to Treblinka during the period from 22 July to 12 September 1942.<ref name="ushmm-uprising">{{cite web |url=http://www.ushmm.org/wlc/en/article.php?ModuleId=10005188 |title=Warsaw Ghetto Uprising |publisher=US Holocaust Memorial Museum |date=10 June 2013 |access-date=25 August 2013 |author=Holocaust Encyclopedia |archive-url=https://web.archive.org/web/20120502213631/http://www.ushmm.org/wlc/en/article.php?ModuleId=10005188 |archive-date=2 May 2012}}</ref>{{sfn|Court of Assizes|1965|loc=excerpts}}

The Polish railway was very heavily used. An average of 420 German military trains were passing through every 24 hours on top of internal traffic already in 1941.<ref name="Bochen">{{cite web |url=http://www.kolejnictwo-polskie.pl/historia-kolei-w-polsce/ii-wojna-%C5%9Bwiatowa/okupacja-1939-1945/ |title=Okupacja 1939–1945 |publisher=Urząd Transportu Kolejowego |work=Kolejnictwo polskie: II wojna swiatowa |year=2015 |access-date=2 November 2015 |author=Antoni Bochen |archive-date=6 January 2015 |archive-url=https://web.archive.org/web/20150106221659/http://www.kolejnictwo-polskie.pl/historia-kolei-w-polsce/ii-wojna-%C5%9Bwiatowa/okupacja-1939-1945 |url-status=live }}</ref> The [[Holocaust trains]]' passage to their destination was routinely delayed; some transports took many days to arrive.{{sfn|Kopówka|Rytel-Andrianik|2011|p=95|ps=: Samuel Rajzman testimony.}} Hundreds of prisoners were murdered by exhaustion, suffocation and thirst while in transit to the camp in the overcrowded wagons.{{sfn|Friedländer|2009|p=432}} In extreme cases, such as the [[Biała Podlaska]] transport of 6,000 Jews travelling only a {{cvt|125|km|adj=on}} distance, up to 90 percent of people were already dead when the sealed doors were opened.{{sfn|Kopówka|Rytel-Andrianik|2011|p=95|ps=: Samuel Rajzman testimony.}} From September 1942 on, both Polish and foreign Jews were greeted with a brief verbal announcement. An earlier signboard with directions was removed because it was clearly insufficient.<ref name="USHMM" /> The deportees were told that they had arrived at a transit point on the way to Ukraine and needed to shower and have their clothes disinfected before receiving work uniforms and new orders.{{sfn|Klee|1988|p=246}}
