The logistics of the Reichsbahn were also an important factor during the Holocaust. Jews were transported like cattle to the concentration and extermination camps by the Deutsche Reichsbahn in trains of covered goods wagons, now known as Holocaust trains. These movements using cattle wagons from the goods station of the great Frankfurt Market Hall, for example, thus played a significant role in the genocide within the extermination machinery of the Holocaust. In 1997, the market erected a memorial plaque in recognition of this dark period of history.
