(Radio Iowa) – A museum exhibit featuring a replica of a rail car used to transport Jews to concentration camps during the Holocaust of World War Two opened in Sioux City. George Linblade designed the exhibit and said the cars actually used in Auschwitz are all the property of the Polish government and they will not let him out of the country. Linblade says every state in the union got a real railroad car courtesy of Poland after the war, but no one knows what happened to the one in Iowa. The rail car was moved to the Sioux City Museum two years ago and the work began on it.
