Exactly 70 years after Nazi German troops packed them into train cars, a handful of Auschwitz survivors gathered Monday to commemorate the first ever rail convoy to the notorious camp.A special memorial train is due to set off Monday morning from the southern Polish town of Tarnow, retracing the original 140-kilometre (87-mile) route to Oswiecim, site of the Auschwitz-Birkenau death camp.A trio of aging survivors are scheduled to travel on the memorial trip organized by the Association of Auschwitz Families, while a further six are expected at a ceremony at the camp itself. A total of 1.1 million people perished at Auschwitz-Birkenau during World War II, according to figures from the camp’s memorial museum. A million were Jews from Poland and across Nazi-occupied Europe. The camp is an enduring symbol of the Holocaust. The other victims included some 75,000 non-Jewish Poles, 21,000 Roma, 15,000 Soviet prisoners of war and up to 15,000 others including resistance members from other occupied nations. The Nazis set up Auschwitz in a former Polish army barracks in 1940, almost a year after sparking World War II by invading Poland.
