Proposals for improving the efficiency of railway track overhaul due to innovative equipment

The article presents a brief overview of the railway track technologies development for the railway track overhaul from 1930 to 2021. The analysis of the number of railway track repairs carried out in the “window” mode and "closed stage mode" is given. The comparison of the volumes of track overhaul repairs, as well as the technologies used in 1968 and 2021, in terms of the productivity of the full range of works, is made. The data obtained during the overhaul of the railway track in 2021 on the West Siberian Railway in terms of the actual production of railway construction machines are presented. The weaknesses of the existing technology in terms of the development of leading machines and uneven loading of personnel on working days are determined. To optimize the time of work and eliminate the uneven needs of the personnel involved in the overhaul of the railway track, it is necessary to revise the technology of work production and create innovative railway construction machines that will increase the productivity of the full range of work on the repair sites. The article presents the results of the proposal development for the modernization of existing equipment, in order to increase the productivity of the full range of work and uniform loading of personnel. Due to the use of innovative equipment during the overhaul of the railway track, both the time of work and the volume of manual labor is reduced.

The article also provides recommendations on the organization of major repairs of the railway track with maximum output at the repair sites in the closed stage mode, taking into account the analysis of the actual operation of each track machine. Increasing productivity during the work on laying the railway track, cutting out contaminated ballast and replacing inventory rails with long-length rail lashes will increase the productivity of the full range of works up to 3000 meters of track per day.
