Abstract
The work reviews the problems that arise when the wheel with flat contacts the rail, the detection and diagnostic methods of the latter. Since all wheel with flat detection methods are very complex and lack precision it was intended to create a simplified mathematical model of changes in sound power level caused by the perpendicular forces that arise when the rail contacts the wheel with flat, theoretic calculations were performed. It was determined that in theory sound power level changes can be utilized to detect and determine such defects. Preliminary values of the diagnostic parameters were calculated, their definition model was presented.
