This 50’ airslide hopper is tan with black lettering and run on 100-ton Barber Roller Bearing trucks. Built by the General American Transportation Co (GATC) for several of CSX’s 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.
