Freight Car Prototypes
Postwar 40' AAR Box Car

Starting towards the end of World War II, the Modified 1937 AAR Box Car continued to be constructed, but with the replacement of the 'standard' Dreadnaught ends with the new 'Improved' Dreadnaught ends, which had four 'rolling pin' corrugations in each of the two end sections. This new variant has been dubbed the Postwar AAR Box Car.
