I’m searching for information on an unscheduled US Army controlled prisoner train that ran through Wurzburg and Nuremburg. Destination was Warsaw. It ran sometime in November 1947 – January 1948, carrying extradited Polish prisoners and convicted Nuremberg Trial prisoners. The coal burning locamotive pulled cattle cars, which had adjustable air vents toward the top and were modified to contain prisoners. I would appreciate any available information such as confirmed dates, origin, manifest of prisoners, photos (preferably high resolution digitals) of the cattle cars and locomotives typically used or any other information.
