Transport No. 46m left Vienna’s Nordbahnhof (Northern Railway Station) on November 30, 1943, and arrived in Theresienstadt on December 1. It consisted of 43 Jews. The average age of the deportees was 47. Four of them were over 61.
Due to the small number of deportees, the security police (Sipo) in Vienna ordered train cars, which were attached to passenger train No. 723 that left daily at 6 PM from Nordbahnhof and travelled via Breclav (Lundenburg) to Brno (Brünn). In Brno, the cars were disengaged and reattached to a train of the "Protektoratsbahnen" (the company that operated trains in the so called "Protektorat") destined for Prague (Praha). From there, the journey continued to Theresienstadt.
Upon arrival, the transport was listed in the ghetto records as IV/14o. The Roman numeral IV represented Vienna as city of origin.
