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. A conveying gas supply line connected to the material conveying line upstream of the horizontal leg of the outtake feeds a main flow stream of a conveying gas into the material conveying line for flow across the downstream end of the horizontal leg of the outtake, whereby granular material moving from the outtake into the material conveying line can become entrained in and conveyed by the main flow stream through the conveying line to the material discharge port. The system also comprises a feeder gas supply line connected to the horizontal leg of the outtake upstream of the vertical leg for feeding a stream of feeder gas into the horizontal leg for moving material from the vertical leg into the material conveying line. The system also includes a blaster arrangement and a unique infeed distributor.
