The Atlas HO Master 50' Plug Door Box Car Burlington RBBX 79521 models the 50' Plug Door Box Car which was introduced in the early 1950s. The initial success in the late 1940s of the 40' refrigerator car prompted the slightly larger 50' model in the early 1950s. The AAR (Association of American Railroads) designation would mean this car was adopted as a standardized design. The plug door is designed to provide its own seal by taking advantage of the pressure difference on its two sides. Releasing the pressure will cause the door to open. The plug door enabled a much tighter seal, which was a great improvement in the design of reefer cars.

Note: While a reefer car is technically a box car with refrigeration, we would have called this product a "Reefer". However, in order to enable you to find the product, we accept Atlas Model's nomenclature.
Burlington Refrigerator Express: In 1923 Great Northern Railway teamed with Fruit Growers Express to form Western Fruit Express to offer competition to the very successful Pacific Fruit Express(itself a partnership between Southern Pacific and Union Pacific), a provider of refrigerated cars along with complementary car service and icing facilities. After the success of Western Fruit Express, Great Northern subsidiary Chicago, Burlington & Quincy Railroad also teamed up (in 1925) with Fruit Growers Express to form Burlington Refrigerator Express. The new venture offered an ever expanding fleet of reefer cars for the burgeoning shipment of fruits and vegetables from rapidly growing farms all over the US West Coast to Midwest and Northeast population centers.
