Therefore, to proceed with a study using the method of mathematical modeling of linear and nonlinear oscillations of subway cars for solving a system of differential equations, it is necessary to have a «generated» random disturbance process. The objective of the authors was to present methodology and results of simulation of equivalent geometrical irregularities of subway track tunnel to solve the problem of research of random fluctuations of passenger cars. The authors used simulation method, mathematical calculations and analysis. Perturbation process, generated for these purposes, is provided by the approximate method of moving summation. Two possible approaches are shown, each of which includes a range of research and computation. Irregularities obtained by those methods can be used to study oscillations of dynamic models of subway cars with a similar load from a wheel set on a rail.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>метрополитен</kwd><kwd>рельсовый путь</kwd><kwd>подвижной состав</kwd><kwd>тоннель</kwd><kwd>геометрическая неровность</kwd><kwd>математическая модель</kwd><kwd>спектральная плотность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>subway</kwd><kwd>track</kwd><kwd>rolling stock</kwd><kwd>tunnel</kwd><kwd>geometrical irregularity</kwd><kwd>mathematical model</kwd><kwd>spectral density</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Поляков А.
