Abstract
A method and apparatus for determining the weight of each axle of a plurality of rail cars of a railroad train passing over a selected section of a railroad track. The apparatus embodies a measuring device that, when mounted to the selected section of the railroad track, measures strain induced in a portion of the track as the rail car passes over that portion of the track to produce an electrical output which is precisely proportional to the load imposed on the portion of the track as each axle of the rail car passes over the portion of the track. The measuring device of the interfaces with a remotely located data processing subassembly that receives the output from the strain gauges and precisely determines the axle weight therefrom.
