A new technologies for production of railway wheels and axles (shot peening, roller burnishing, protective coating) were described. The aim of the technologies was to increase the fatigue strength of railway wheel sets and increase their reliability in railway service. Together with putting the methods into practice, the development of new methods for the quality evaluation of the final products was necessary. The required non-destructive testing method for determination of higher fatigue strength values under real loading in service should be elaborated to be applied on all products with sufficient measurement accuracy. The new methods for the evaluation and certification of product quality during serial manufacture (Almen test, resonance test, reflection method, strain gauge method, Wirotest device, adhesion measurements), including a description of verification tests and their reliability, were described.
