Transport No. 31 departed at 7:25 pm from Aspangbahnhof in Vienna (Wien) on July 14, 1942 and arrived in Theresienstadt on July 15. The transport consisted of 1,001 mostly elderly Jews. 953 deportees were older than 61, the average age of the deportees was 72 years.
Six armed guards from the Security Police (Schutzpolizei) under the command of Lieutenant Johann Pflamitzer watched over the expelled Jews throughout the journey. The train's route took it through Vienna’s Nordbahnhof, Floridsdorf, Jedlersdorf, Stockerau, Absdorf-Hippersdorf, Gmuend, Tabor, Prague (Praha) and Bohusovice. At the rail station in Bohusovice, the Jews were taken off the train and forced to make their way to Theresienstadt on foot, a distance of about 3 km. The transport was given the reference IV/4 in the Theresienstadt ghetto listings; in this regard the Roman numeral IV refers to Vienna.
Many of the elderly Jews aboard these transports succumbed in Theresienstadt to starvation and disease during the summer months. Others were deported in October 1942 from Theresienstadt to Treblinka, where they were murdered.
