A method and apparatus are provided for loading railroad cars coupled in motion. Prior to loading, an "empty" composite weight is obtained of the front and rear trucks of an empty selected railroad car, the rear truck of the adjacent forward railroad car with load and the front truck of the adjacent rearward railroad car. This "empty" composite weight is stored in a memory. The dynamic composite weight during loading is sensed. A desired net weight of the load (to be loaded into the selected railroad car) is selected. A total composite weight that is equal to the "empty" composite weight plus the desired net weight of the load is stored in a memory. The selected railroad car is loaded until the dynamic composite weight appears equal to the total composite weight. The actual net weight of the load is then determined by substracting the empty composite weight from the actual total composite weight. By loading the selected railroad car in this manner, the net weight calculation will not be subject to error caused by weight transfer through couplers. |
