A bulk material carrier in a bulk material transport system includes a high strength high density polyethylene (HDPE) flexible sheet material attached by clamps at two opposite edges to box beam supports forming a bulk material carrying sling, e.g., for carrying bales of municipal waste. The supports extend beyond the sheet material forming extensions. Rail gondola cars and truck trailers are fitted with frames which releasably secure the support extensions. Pocket members secured to the frames releasably secure the extensions and supported carrier during transport of the rail car or truck to preclude displacement of the supports and carrier horizontally. The rail car frames form four carrier receiving compartments and a truck trailer frame is arranged to carry a single carrier. The supports have fork lift truck pockets to permit the loaded or empty carriers to be transferred between rail cars and truck trailers.
