Abstract:

A method for loading particles, such as coal, into a plurality of railroad cars wherein a control weight of a railroad car loaded with particles is established. Each of the railroad cars is weighed prior to loading particles into the railroad car from a weigh bin to determine an unfilled weight of each railroad car and the unfilled weight of each railroad car is compared with the control weight to determine an unfilled differential weight for each railroad car. The particles are loaded into the weigh bin from a surge bin and the surge bin is weighed as the particles are being loaded into the weigh bin from the surge bin so the loading of particles into the weigh bin can be terminated when a weight of particles has been loaded into the weigh bin about equal to and less than the unfilled differential weight associated with the railroad car to be loaded with the unfilled differential weight of particles.
