Приведен ретроспективный анализ норм выбора наибольшей разности уклонов смежных элементов профиля и наименьшей длины разделительных площадок и элементов переходной крутизны. Подчеркнута актуальность оценки влияния различных сочетаний плана и профиля железнодорожного пути на показатели взаимодействия пути и подвижного состава, особенно в современных условиях развития систем автоматизированного проектирования железных дорог. Представлены результаты моделирования движения грузовых вагонов на участках с различным сочетанием плана и профиля железнодорожного пути в программном комплексе «Универсальный механизм».</p></abstract><trans-abstract xml:lang="en"><p>Modern level of development of automated systems opens up great opportunities for designers, making it possible to find optimal solutions for the construction of the railway track using digital modeling methods and automated programs. Moreover, the expansion of technical capabilities should be based on a responsible approach to choosing configuration of the railway track, its parameters in plan and profile. The article is devoted to the study of the influence of the parameters of the railway track in plan and profile on the interaction indicators of the track and rolling stock. Author presented a retrospective analysis of the norms for choosing the largest difference in the slopes of adjacent profile elements and the smallest length of separating pads and transition steepness elements. Also shown is the dependence of the length of separating pads and elements of transition steepness and the dependence of the algebraic difference of the slopes of adjacent elements of the profile of railway lines on the weight of the train with different linear loads. The results of modeling the freight cars running in sections with different combination of the plan and profile of the railway track in the software package “Universal Mechanism” are presented. During the modeling, the dependence of the frame forces on the algebraic difference of the matching slopes was obtained, and a comparative analysis of other indicators of the interaction of the track and rolling stock (lateral forces, vertical forces, longitudinal forces, stability margin) was carried out. The article conclusions summarize the results of the calculations and give recommendations for calculations and modeling the effect of a combination of vertical curves and curves in plan on the indicators of the dynamic interaction of the track and rolling stock.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>железнодорожный путь</kwd><kwd>длина приемоотправочных путей</kwd><kwd>уклон</kwd><kwd>вес поезда</kwd><kwd>взаимодействие пути и подвижного состава</kwd></kwd-group><kwd-group xml:lang="en"><kwd>railway track</kwd><kwd>length of reception and departure tracks</kwd><kwd>slope</kwd><kwd>train weight</kwd><kwd>interaction of track and rolling stock</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">СНиП II­Д.1 – 62.
