| These 50 
                airslide hoppers are tan with black lettering and run on 100-ton 
                Barber Roller Bearing trucks. Built by the General American Transportation 
                Co (GATC) for several of CSXs constituent roads  Seaboard 
                System, Chessie, and C&O, they were renumbered as the series 
                203402-203448. These cars were specifically designed for use with 
                fine-grained commodities, like powdered sugar, that could settle 
                en-route making unloading difficult. |
