Abstract
A railroad wheel impact load detection test panel includes a secondary instrumentation rail proximate a field side of a primary or running rail of a section of railroad track, and elevated a prescribed distance so that the wheels of a rail car traverse the instrumentation rail within the test panel. The instrumentation rail includes an optical strain gauge to sense the wheel impact load. The sensed impact data is correlated with wheel damage signatures to identify wheels to be restored or replaced before failure occurs.
