The ACF 5701 grain hopper is similar to its 5701 plastics relative except it is equipped with continuous loading hatches and gravity outlets. The larger size was needed to transport lower density grain-related and similar agricultural products (e.g. feed, sunflower seeds etc) more efficiently than the then standard 4650, 4740, and 4750 cubic foot capacity grain hoppers. These were originally built as 263,000 GRL (Gross Rail Loading) cars but many have recently been rebuilt into the higher 286,000 GRL.

Eight full-width panel body with nine weld seams
