In early 1945, Kasztner traveled to Germany with Becher, who had received the money and valuables paid to save the Jewish lives on the train. Himmler had ordered Becher to attempt to stop further exterminations at the concentration camps as the Allies gained further ground in the closing days of World War II. Even though Kasztner was a Hungarian Jew and Becher was head of the Economic Department of the SS, Kasztner and Becher worked well together. This 1945 action is credited by some for saving tens of thousands of Jewish lives Anna Porter, "Kastner Train". Others consider Kasztner to have been a collaborator.
