cze	Anlýza provozního opotřebení jízdní plochy železničního kola	Description of structural changes in railway wheels during operational period. The nature of structure was investigated using light microscopy and microhardness. Our study characterized two basic mechanisms of cracking formation - thermal initialization and contact-fatigue damage. These two mechanisms can generate different structures, but both contribute to irreversible degradation on the surface of railways wheels.	wheel treads, structure analysis
