Stalinist pressure for rapid industrialization and appreciation for economies of scale brought about the construction in the late 1920s and early 1930s of massive factories manufacturing highly standard vehicle and slowly changing product lines. Construction of the Moscow (ZIL), Gor‘kiy, and Yaroslavl' plants, partly or totally built by Western firms, increased production from a few thousand vehicles in 1928 to 200,000 vehicles in 1937, nearly all of them trucks.
