Abstract
An important direction of development of digital technologies for track repairs is to control the parameters of the operation of track machines when performing track repairs. At the moment, all types of technological machines are actively implementing various monitoring systems that transmit data about the operation of machines in real time. In world practice, various sensors are widely used to automate control functions, but their use requires criteria for evaluating the transmitted data. In accordance with the requirements of JSC “Russian Railways”, when carrying out track repairs at railway infrastructure facilities, it is necessary to perform operational quality control of technological operations, during reconstruction and repairs of the railway track to ensure that there are no hidden defects that affect the long-term stable condition of the track. The approach proposed in the paper to assess the quality of ballast compaction makes it possible to control the parameters of working equipment functioning that affect the quality of work, and thus will reduce the number of unscheduled track repairs carried out due to improper operation of equipment.KeywordsRailway trackCrushed stone ballastSleeper paddingTrack machines
