Abstract
The paper presents a method for assessing risks associated with fractures and defects of side frames of freight car bogies. The construction of a risk matrix as per manufacturers of side frames, including the assessment of the impact and the frequency of events related to the fractures and detected defects of side frames, is considered. The proposed method is aimed at providing support for making management decisions as to further operation of freight cars on the basis of risk management.
