OPTIMIZATION IN RAILWAY TRACK DESIGNS IN ORDER TO FACILITATE

Abstract

The article proposes a method for justifying the choice of a lightweight structure for the upper structure of a railway track. As a result, there is no single structural and technical solution for the construction of the track, since the list of possible solutions is diverse. Based on the methodology for assessing economic efficiency, a method was developed for determining the coefficient of change in the cost of maintaining the upper structure of the track, taking into account changes in stresses in its elements, depending on the design decisions made. Based on the proposed methodology, technical solutions for laying a lightweight track structure were substantiated, and various options were proposed. For the proposed options, the coefficients of disruption of changes in the intensity of the condition of the railway track and the coefficients of changes in the cost of its ongoing maintenance in the average operating conditions of the network were determined.
