5. Hitler's Holocaust Railways Finale

Chris Tarrant explores the darkest chapter in the history of the railways, their role in the Nazi Holocaust of WWII. Traveling through three countries, he takes a railway journey that will chronicle how the Holocaust evolved during a 10 year period from 1935 to 1945, starting in Nuremberg and ending at the death camps of Auschwitz. The programme explores the history step-by-step, starting with the implementation of the first anti-Jewish laws and the Nazi’s simultaneous quest to build the world’s most powerful railway. Chris investigates how thousands of trains involved in the war were also used to deport millions to ghettos and death camps. He meets holocaust survivors who suffered for days on board cattle trucks and hears their tales of horror, death and heroic acts of bravery. He meets people who worked on the railways and historians who will argue that the Holocaust was neither planned nor inevitable and that it wouldn’t have been possible on such a scale without Hitler’s railways.
