Abstract: A method of distributing railroad ties or other materials in variable quantities at randomly spaced intervals. GPS coordinates are recorded for individual use locations where ties or materials are required. From the coordinates of these use locations, drop locations are selected at which materials can be conveniently dropped for subsequent use or installation. Capture of the use location coordinates is done by separate equipment from the distribution equipment, so that the data capture and distribution crews can work at their own efficiencies. The apparatus can be built into new railroad equipment or the like, or can also be manufactured in such a fashion as it can be retrofit. Computer software for the optimization and location of the drop locations is also disclosed.
