Abstract: A system and method for transporting and handling in bulk by rail granular material and, in particular, phosphorous pentasulfide granules, is characterized by a hopper for containing the granular material in one or more hopper sections, and an outtake for each hopper section having a vertical leg connected to an outlet opening at the bottom of the hopper section and a horizontal leg into which material drops from the hopper through the bottom outlet opening and the vertical leg. A material conveying line connects the downstream end of the horizontal leg of the outtake or outtakes to a material discharge port through which the material is unloaded from the hopper.
