Abstract
A system for detecting a thin wheel flange and condition and a loose wheel condition of railroad wheels includes relatively movable contacts actuated by the passing wheels and triggering switches when the contacts move together into a spacing less than a predetermined flange thickness. Opposing contact arms bearing against back faces of the rims of the opposing wheels are interconnected for detecting a loose wheel condition upon the closing of an electrical circuit including microswitches and electrical contacts which close when the opposing wheels are spaced less than a predetermined distance apart.
