The murder of millions of Jews in the extermination camps in Poland required the use of mass transportation by railroad. The Nazis organized thousands of transports from all over Europe, involving many tens of thousands of railroad employees, engineers and guards.

Jews were herded onto freight or cattle cars and deported to the extermination centers by the thousands.  he train cars had no seats, no toilets, no food or water, no amenities of any sort. Transports often took many days, sometimes in extreme heat or cold weather.  A great many people died during the transports. Those who made it to the final destination were murdered upon arrival in gas vans or gas chambers or, if healthy enough, chosen for forced labor.
