For compacting the ballast layer in the tie cribwork there was designed a rotary device. In order to select rational parameters of the device, there was carried out a kinematic analysis of sleepers` burnishing. The parameters influencing the effectiveness of the ballast layer compaction were determined. To calculate the technology parameters and operation mode of rotary device performance for compaction of the ballast layer in the tie cribwork, there has been developed a mathematical model and a software program for the calculation automation. Using the developed program there was performed an analysis of the operation mode of the device. The analysis results allow determining rational parameters of the rotary device operation mode. Recommendations for technology of using the device are presented.
