40' Postwar Box Car

Prototype Information

The 40′ postwar boxcar emerged after World War II as railroads replaced aging wood-sided equipment with modern all-steel cars. These boxcars typically featured welded steel construction, Youngstown or Superior sliding doors, and either riveted or welded ends and roofs. They conformed to Association of American Railroads (AAR) standards developed during the war, including improved underframes and standardized appliances. Used for general freight, they dominated American railroads through the 1950s and into the 1960s, before being supplanted by longer 50′ cars better suited to new palletized shipping methods.
