Unlike the Airslide, which forced pressurized air up through a fabric liner to help fluidize the cargo, the PS series of hoppers applied both a positive pressure of about 15 lbs. psi above the outlets as well as a vacuum at the outlet to help draw the cargo from the car. This design was well suited to products with very small particle size, such as talc, clay, plaster, and cement which would readily foul the fabric liner in an Airslide design. In addition, since the upper hatches did not need to be opened during unloading, the PD hopper was also ideal for transporting goods where contamination by outside air, dirt, or moisture could affect the load.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp align=\"justify\"\u003e\u003cspan style=\"font-family: arial, helvetica, sans-serif; font-size: 10pt;\"\u003eThe Atlas 5-bay PD5000 hopper is based on the original North American Car Company (NACC) design for a 5150 cu ft PD covered hopper, which was later manufactured as a 5125 cu ft model by Trinity Industries. These cars were mostly provided as lease cars, and as such, carried many colorful schemes and product logos during their lifetimes, however several major railroads such as Norfolk Southern purchased fleets as well.\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"story\"\u003e\n\u003cstrong\u003e\u003cspan style=\"font-family: arial, helvetica, sans-serif; font-size: 10pt;\"\u003eModel Features:\u003c\/span\u003e\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan style=\"font-family: arial, helvetica, sans-serif; font-size: 10pt;\"\u003eAll-new end cage tooling\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-family: arial, helvetica, sans-serif; font-size: 10pt;\"\u003eEtched metal roofwalk\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-family: arial, helvetica, sans-serif; font-size: 10pt;\"\u003eDistinctive flat side\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-family: arial, helvetica, sans-serif; font-size: 10pt;\"\u003eFree-rolling trucks\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv align=\"justify\"\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cspan style=\"font-size: 14pt;\"\u003e\u003cem\u003e\u003cspan style=\"color: #ff0000; font-family: arial, helvetica, sans-serif;\"\u003e\u003cstrong\u003eLombard Hobbies = Big Inventory ∙ Value Pricing ∙ Fast Shipping ∙ Great Service\u003c\/strong\u003e\u003c\/span\u003e\u003c\/em\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Atlas N","offers":[{"title":"Default Title","offer_id":48320515276953,"sku":"ATL50005666","price":27.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0685\/8847\/0425\/files\/n50005665__65009.1756494463.1280.1280__83488.1756495513.1280.1280.jpg?v=1784162202","url":"https:\/\/lombardhobby.com\/products\/atlas-master-n-50005666-trinity-pd5000-covered-hopper-adm-admx-51178","provider":"Lombard Hobbies","version":"1.0","type":"link"}
