Abstract
Ensuring the stability of the track geometry is an integral part of the current track maintenance. Track straightening accounts for a third of all labour costs at the track distance, the state of the track geometry affects the safety level of driving and determines the efficiency assessment of the structural subdivision. Track straightening by level, plan and profile is carried out both manually by a team of track installers, and due to the operation of the machine complex as part of the planned preventive track straightening. In the context of the workers shortage, a natural question arises about reducing labour costs due to the mechanization of the main technological processes to maintain the track.
This paper presents the results of a study on the analysis of the dependence between periodicity of preventive maintenance and the state of track geometry, including taking into account the required labour costs for manual track straightening. Sections of the Central Siberian passage with the value of the passed tonnage from 300 to 1200 million tons with different frequency of machine straightening were selected for the analysis. To process the initial data for the analysis, the Python programming language was used, which made it possible to automate the process of calculating the required labour costs for manual straightening of the path. The article shows the dependence of labour costs for track maintenance depending on the amount of missed tonnage, taking into account the periodicity of planned preventive straightening. Degree of track straightening efficiency is determined by machine complex depending on value of passed tonnage and number of straightening. It was noted that in the conditions of a shortage of working personnel for the purpose of planned and preventive straightening, it is rational to use an additional criterion – the amount of labour costs for straightening the track, since this parameter directly reflects the labour intensity of maintaining the rail track on the linear section.
