Abstract: A railroad wheel defect-detecting device is described. An accelerometer senses the vibrations induced in a test rail by a railroad wheel traveling thereon. The test rail is vibrationally isolated from adjacent train tracks and ground vibrations to permit sensing of train wheel defects such as flat spots on wheels, loose couplings, dragging equipment and the like. Defects are recognized when the sensed vibrations exceed preselected maximum tolerable levels, said levels being fixed or automatically regulated to compensate for varying train conditions. Identification of each wheel having a defect is provided as well as optional car identification.
