Walthers Mainline 50' 2-bay Airslide® covered hopper, ready to run. Santa Fe #310546 (gray, black, billboard lettering). Prototypes in service 1960s to modern era. Conceived in the early 1950s, the Airslide covered hopper design was developed for dry bulk ladings such as flour, starch, sugar and plastics. Prior to the late 1940s, such ladings would have been packaged and shipped in boxcars, even for car load shipments. This added extra labor and time to package, load the containers in the boxcar, unload, and remove the lading from the shipment containers. Beginning in the late 1940s, covered hoppers greatly simplified the process by allowing the bulk material to be loaded in through roof hatches, and dumped out of the hopper bays.\u003cbr\u003e\u003cbr\u003eHowever, dry, powdery commodities such as flour, starch, sugar and plastic granules do not always flow easily from a standard hopper bay; they have a tendency to compact and cake up in the bay, impeding the unloading process. To solve this problem, the Fuller Company of Catasauqua, PA patented the Airslide concept. In an Airslide covered hopper, the bays are formed into two narrow, steep-sided troughs with a layer of an air-permeable fabric material at the bottom. Air is pumped through the material, causing the lading to fluidize and flow easily through the hopper outlets, the air allowing the lading to more easily slide out of the car.\u003cbr\u003e\u003cbr\u003eIts key features are:\u003cbr\u003eLimited edition - One time run of these road numbers!\u003cbr\u003eCorrect 33 turned-metal wheel\u003cbr\u003eProto MAX™ metal knuckle couplers\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eCondition:\u003c\/strong\u003e Factory New (\u003ca href=\"#\" title=\"C-9: All original; unused; factory rubs and evidence of handling, shipping and factory test run.
