Steel boxcars became a common site in the post-WWII period (also known as the transition era). Steel construction resulted in a lighter, lower-maintenance car that was less expensive to acquire and operate. The economies of scale that happened during the war along with a cessation of orders from the military resulted in a plentiful, inexpensive source of metal and aluminum for the railcar manufacturers which in turn led a complete replacement of the aging wood-sheathed fleets with new steel cars.
