The PS-2CD 4785 Covered Hopper was a missing variation in the Pullman-Standard Covered Hopper family until now. The 4785s low side sill visually differentiates the carbody from its high sill siblings (4727, 4740, and 4750). Since the 1960s, these cars have crisscrossed North America in singles and groups of hoppers.

To maintain a value price point, the Operator series model features a common body with continuous ribbed trough hatch, tall vertical end supports, and short outlet gates.
