ABSTRACT:
An electronic coupled-in-motion railroad track scale is disclosed and comprises four track logic switches for detecting forward or backward train axle movement, a programmable digital voltmeter connected to load cells for effecting the weighing of the train cars, and a computer (CPU) for controlling the voltmeter as well as the track logic switches, and for correlating the axle numbers to the weight determined for each particular car. The four track switches are situated such that two switches are located in close proximity on either end of the weighbridge and the train track interface. Together with the logic circuits, the switches indicate when an axle comes on or goes off the weighbridge, and in which direction the axle is moving. In this manner, if reweighing is desired, the train may be backed up or forwarded to the particular car in question without reweighing the entire train.
