Abstract
A method for loading a moving railroad car from front to back with a target weight of particulate material from a loading unit having a silo and first and second weigh bin, which bin means have a combined material weight capacity of less than the target weight, the method comprising the steps of: PA1 (a) making a first charge of material into the first bin; PA1 (b) discharging a first quantity of material from the first bin into a forward portion of the car; PA1 (c) making a second charge of material into the first bin; PA1 (d) discharging a second quantity of material from the first bin into a rearward portion of the car, wherein the weights of the first and second quantities are determined and, as a combined weight, is less than the target weight; PA1 (e) making a charge of material into the second bin; PA1 (f) discharging from the second bin into the car a topping quantity of material equal in weight, to within about 0.5%, to the target weight less the combined weight, to thereby attain, within very close limits, the target weight of material in the car; and PA1 (g) wherein either or both of the charging step of (e) and the discharging step of (f) may be initiated at any conveni…
