ABSTRACT:
A direct measuring loaded gage axle assembly that measures track strength by directly measuring constant load on split axles as vertical loads are imposed by a hydraulic ram, and horizontal loads being supplied by horizontal rams through split axles and steel wheels to the railroad tracks enabling improved calibration to measure changes in track gauge indicating track strength condition and further including electronic data recording and comparison.
