UM MT 609 Soviet OB-3 Railroad Armored Car with T-26-1 (1937-39) Turret

OB-3 is a Soviet armored draisine from the interwar period and World War II. Serial production started in the second half of the 1930s. The armament consisted of one or two 45mm guns mounted in rotating turrets and 5-6 DT 7.62mm machine guns. The crew consisted of 10 to 12 people. The OB-3 draisine was constructed on the basis of a two-axle goods wagon with a load capacity. Armor plates with a thickness of 30 to 40 mm and - depending on the version - one or two towers for the main armament of the draisine were added to the wagon. It is worth adding that it was placed in the same turrets that were mounted on the T-26 mod. 1933. OB-3 draisines took an intensive part in the beginning of the German-Soviet war of 1941-1945, and their production at that time took place, among others, in Leningrad and Moscow.
