The comparative analysis is based on the results of the static strength analysis of an Y25Ls-K bogie frame and the tests that have been carried out. Strength calculations have been made using the Finite Elements Method at the Department of Railway Engineering at the Technical University – Sofia and the tests of the bogie frame have been conducted in VUZ Testing laboratory in the Czech Republic. It was found out that the stress results are very similar, especially in the areas with maximal values. This proves that a suitable calculation model with a relatively small number of finite elements can be developed. This allows us to solve a wide range of problems concerning the improvement of the bogie frame with similar construction.
