Abstract
An overview of modern research on the design of the longitudinal profile of marshalling yards is given. The analysis of the current regulatory requirements for the design of the longitudinal profile of the sorting tracks and methods for regulating the speed of rolling off cuts when detaching from the gravity humps is carried out. A description of a simulation model of filling the tracks of train accumulation during detaching is presented, which is used to study the configuration of the longitudinal profile of the main part of the tracks of marshal ling yards. Criteria have been established for assessing the configuration of the longitudinal profile of the main part of the marshalling yard tracks, based on the calculation of probabilities characterizing the indicators of the process of filling the tracks of train accumulation during disbandment. A methodology for assessing the design parameters and configuration of the longitudinal profile of the main part of marshalling tracks has been developed based on simu lation modeling of the process of filling the tracks for accumulation of trains using the interval targeted speed control mode for rolling off cuts. A study of various configuration options for the longitudinal profile of the main part of the tracks of the marshalling yard for existing and new values of the main specific resistance to movement of cars when rolling down a hump has been carried out.
