The Plug-Door Boxcar was designed to provide a better seal and a more insulated interior for materials being transported by rail. Featuring a specialized door system that closed inward, sealing flush against the bodyside, the design allowed railroads to provide better temperature control for transporting non-refrigerated produce, while also maximizing the space available for loading goods inside the car. 50' Plug-Door Boxcars such as the car our model portrays first arrived on railroads in the 1950s and lasted in mainline service into the 1980s. Today, the plug-door design continues to be a popular choice for hauling bulk goods and materials that require environmental control. Bachmann’s Plug-Door Boxcar comes in a variety of authentic paint schemes, representing prototypical railroads from both the past and present. Each car arrives fully assembled and features a highly detailed painted body with precision graphics, blackened metal wheels, magnetically operated E-Z Mate® couplers, and added weight for optimum tracking performance
