The 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.
