In 2010, a special exhibition of the Documentation Center Nazi Party Rally Grounds in Nuremberg extended for the first time through all available special exhibition spaces on the ground floor. The sheer size of the exhibition alone already suggested the scope of the Holocaust and the responsibility of what was then the Reichsbahn railway for deporting people. The exhibition named "The Track. The Logistics of Racial Mania" was a joint German and Polish project, with live connections that brought the sites of extermination in Poland back to the place that was inseparably tied to Nazi crimes by the promulgation of the "Nuremberg Laws" of 1935 – the Nazi Party Rally Grounds in Nuremberg.
