In this article it is given proof of the method of the principal components to the analysis of calculation of the stress-deformed condition of the wheel pair of the freight car. The statistical result estimation method allows to get mathematical models for researching parameters of the reliability of the wheel pair at changing of loading parameters. %U http://transportproblems.polsl.pl/pl/Archiwum/2009/zeszyt4/2009t4z4_02.pdf
