Superelevation of outer rail on a curved track is determined today by taking into account the limiting unbalanced accelerations and train speeds calculated either on the basis of traction calculations or by means of statistical analysis. Maximum allowable unbalanced accelerations in this case will be accelerations equal to 0.7 m/s2 for passenger trains and ±0.3 m/s2 for freight trains. The fact that the accelerations reaches limit values indicates that the superelevation of the outer rail will be not optimal but only the maximum allowable. In order to determine the optimal values of superelevation, it is necessary to find such optimal unbalanced accelerations that will not contradict the limiting values and will give the least amount of defects in the elements of the track superstructure. In other words, it is necessary to determine the acceleration, which would allow operating a curved track effectively in terms of train safety and in terms of saving money during the inter-repair cycle. The article considers the issues of determining the optimal unbalanced acceleration on curved tracks with a more detailed consideration of the work associated with the replacement of rails because of side wear. The concept of inter-repair cycle and life cycle, probability theory and data approximation are used in the calculations.
