A system and method for handling and transporting moist bulk grain by-products include a rail car having an aluminum car body carried by a plurality of trucks for engaging rails. A flexible top cover, supported by a plurality of breakaway curved ribs, is positioned over an open top of the rail car to protect the moist bulk grain by-products carried therein. The car body has a front end and a rear end each having a wind screen for spoiling or deflecting the flow of air over the car as it moves to prevent the flexible top cover from being lost or damaged. The car may be emptied by a car inverter over a conveyor, such as a reciprocating floor which carries the moist grain by-products to a mixer, or transportation vehicles for distribution to customers or users of the grain by-products.

What is claimed is: 1. A method of supplying a bulk quantity of moist grain by-product using rail transport, the method comprising: loading a bulk quantity of moist grain by-product into an invertible railroad container to provide a railroad container which contains moist grain by-product; transporting the railroad container containing moist grain by-product; and inverting the railroad container with the grain by-product thereby removing the moist grain by-product from the inverted railroad container, wherein the moist grain by-product has a moisture content of about 30% to about 70% by weight. 2. The method of claim 1, further comprising: covering the moist grain by product in the railroad container; and uncovering the moist grain by-product in the railroad container prior to inverting the railroad container to remove the moist grain by-product. 3. The method of claim 2, further comprising covering the moist grain by-product with a tarp. 4. The method of claim 2, further comprising removing the moist grain by-product from the inverted railroad container to at least one grain moving device which is below a grade of the inverted railroad container. 5. The method of claim 4, further comprising transferring the moist grain by-product from the grain moving device to a transportation vehicle for distribution to users of the moist grain by-product. 6. The method of claim 1, wherein inverting comprises rotating the railroad container at least about 120 to about 180 degrees. 7. The method of claim 1, wherein the moist grain by-product is selected from the group consisting of corn gluten feed, corn gluten meal, corn grits, and wheat bran. 8. The method of claim 1, wherein the moist grain by-product is selected from the group consisting of corn gluten feed, corn distillers grains, distillers grains with solubles, and corn bran. 9. The method of claim 1, wherein the moist grain by-product comprises corn gluten feed. 10. The method of claim 1, further comprising: loading a bulk quantity of moist grain by-product into about 50 or more invertible railroad containers; arranging the railroad containers in a train of railroad containers; transporting the train of railroad containers containing moist grain by-product; and inverting the railroad containers with the grain by-product thereby removing the moist grain by-product from the inverted railroad containers, wherein the moist grain by-product has a moisture content of about 30% to about 70% by weight. 11. The method of claim 10, wherein loading a bulk quantity of moist grain by-product into about 50 or more invertible railroad containers comprises filling each of the 50 or more invertible railroad containers with moist grain by-product. 12. A method of supplying a bulk quantity of moist cereal grain by-product using rail transport, the method comprising: loading a bulk quantity of moist cereal grain by-product into an invertible railroad container to provide a railroad container containing cereal grain by-product; covering the moist cereal grain by-product in the railroad container; transporting the railroad container containing moist cereal grain by-product; uncovering the moist cereal grain by-product in the railroad container in which the by-product was covered; inverting the railroad container with the moist cereal grain by-product, thereby removing the moist cereal grain by-product from the railroad container; and removing the moist cereal grain by-product from the inverted railroad container onto a grain by-product moving device which is below a grade of the inverted railroad container, wherein the moist grain by-product has a moisture content of about 30% to about 70% by weight. 13. The method as recited in claim 12, further comprising transferring the moist cereal grain by-product from the grain moving device to a transportation vehicle for distribution to users of the moist cereal grain by-product. 14. The method as recited in claim 12, wherein the railroad container is aluminum and the covering of the moist cereal grain by-product is a flexible tarp. 15. The method of claim 12, wherein the moist cereal grain by-product is selected from the group consisting of corn gluten feed, corn gluten meal, corn grits, and wheat bran. 16. The method of claim 12, wherein the moist cereal grain by-product is selected from the group consisting of corn gluten feed, corn distillers grains, distillers grains with solubles, and corn bran. 17. The method of claim 12, wherein the moist cereal grain by-product comprises corn gluten feed. 18. The method of claim 12, further comprising: loading a bulk quantity of moist cereal grain by-product into about 50 or more invertible railroad containers; arranging the railroad containers in a train of railroad containers; covering the moist cereal grain by-product in the railroad containers; transporting the train of railroad containers containing moist cereal grain by-product; uncovering the moist cereal grain by-product in the railroad containers in which the by-product was covered; inverting the railroad containers with the moist cereal grain by-product, thereby removing the moist cereal grain by-product from the railroad containers; and removing the moist cereal grain by-product from the inverted railroad containers onto a grain by-product moving device which is below a grade of the inverted railroad containers, wherein the moist cereal grain by-product has a moisture content of about 30% to about 70% by weight. 19. The method of claim 18, wherein loading a bulk quantity of moist cereal grain by-product into about 50 or more invertible railroad containers comprises filling each of the 50 or more invertible railroad containers with moist cereal grain by-product.
