“…Quite a number of scientific researches are devoted to the choice and application of the optimal method in terms of the peculiarities of a specific technological or transport process [1][2][3]. However, in relation to rolling stock energy efficiency control, despite the multitude of implemented organisational and technical solutions, there are no definite scientific approaches.…”

The paper describes the main methods of ensuring the energy efficiency of rolling stock, and justifies the main generalised functional quality indicators of control systems. There is a description of possible approaches to a comparative assessment of the feasibility of choosing a control method. A proposal to use a generalized target functional for minimizing the cost components of the control processes has been made. The results of the research make it possible to state that economic feasibility and minimisation of labour and material costs for control are the mandatory requirement when choosing methods of controlling the energy efficiency of rolling stock. It is shown that the control of parameters necessary for accounting and planning can be ineffective because of the high cost of acquisition and maintenance of control tools. Expressions for determining the components of the total cost of control are presented. In general terms they consist of the cost of control, the cost of measurement errors and the cost of machine downtime during control. A control system based on an algorithm for measuring fuel consumption by measuring the electrical power of a diesel generator has been developed. The replacement of average normative values of fuel consumption by actual values of total and specific fuel consumption makes it possible to increase the objectivity of rolling stock energy efficiency control.

“…Ballast compaction quality after tamping process and its influence on the following ballast resilience during operation was studied in papers by Sysyn M. et al and Ilinykh A. et al [26,27]. A method for prediction of track quality deterioration is proposed, which takes into account maintenance works, subgrade stiffness superstructure, and operational properties.…”

Ballast layer is the most weak element of railway track that causes track geometry deterioration. At the same time, it is subjected to intensive particle breakage during the corrective tamping. This causes high maintenance costs of ballasted track. The present paper is devoted to the study of tamping methods. The present machine tamping methods are considered and compared. The possible influence of the tamping technology on the ballast-related maintenance costs is analyzed. The side tamping technology is studied in detail with theoretical and experimental methods. The process of material transport during the side tamping is studied using a scale model of ballast layer and photogrammetric measurements. A theoretical finite element model (FEM) is validated to the experimental results. The study shows that the side tamping is a promising method for the development of a universal, superstructure independent tamping technology.

This paper dwells upon securing solid cargo on a railcar. Transverse cargo shift and forces of elastic securing devices. The authors sought to calculate the shearing force acting on the elastic securing elements and retention bars; the retentive forces that prevent cargo from shifting across the car (the transverse shift); the transverse cargo shift; the force of elastic securing elements as exposed to transverse forces. This study relies on the second law as applicable to relative motion for a frictional constraint, as known in theoretical mechanics. The paper presents the calculated shearing and retentive forces. The authors calculated the equivalent stiffness of elastic securing elements. They thus computed the transverse shift (displacement) of cargo and the elongation of each elastic element that secures the cargo. They also found the forces of elastic securing elements as exposed to transverse forces. It was thus discovered that the forces of the second securing pair were more than double the acceptable limit, which would cause that pair to break during transport. To make the second elastic pair stronger, one might double the number of retention-bar fasteners so that the forces of the second fastening pair wouldn’t exceed the limits. An example of calculation is useful in developing a new methodology for calculating the elements of cargo securing on a car. The calculation results proved that to ensure guaranteed safety and reliability of the transportation process, it is necessary to either increase the number of securing elements of the retention bar, or increase the number of elastic securing elements with subsequent recalculation of forces in all elastic securing elements.
