“…In this context, the European Union would be interested in the experience of the Russian Federation, which has long been one of the leaders in the development of rail transport. The concept of reducing shunting time has been implemented in our country since the 2000s and a large number of articles have been devoted to it [12][13][14][15][16][17][18][19][20][21][22].…”

Developing rail transport is one of the world's greatest challenges. Rail transport reduces emissions and is the most energy efficient means of transport. An important element of the railways is a hump yard, where rolling stock is formed. The purpose of this article is to describe the mathematical apparatus for calculating the speed of a multiple unit train at a marshalling yard. As a calculation method, the articulated-axis model is used. In this model, the trailer is not seen as a material point, but as several physical bodies. Due to this model, it is possible to simulate multi-carriages moving along heterogeneous profile. It was found that for multi-car trailers the spread of the main co-protection will be lower than for single-car trailers. In addition, as a result of accounting for multi-car trains, the profile requirements are reduced when calculating marshalling yards. The results obtained can be used to design hump yards and automate existing hump yards.

“…In order to transport cargo safely and uninterruptedly using railway, all elements of railway infrastructure must function without failures. According to researches [1][2][3][4][5][6] main safety focus is on railway automatics and signalling, shunting movement, level crossings and turnouts or points. All of these elements are not heavily dependent on weather conditions except points.…”

The article discusses the possibility of applying the results of regression analysis [1], fuzzy logic modelling and adaptive systems as such for use in heating control circuits of railway turnouts in order to reduce energy consumption, reduce current surges during on/off switching, and extend the life of heating elements. Based on various researches [2-4] some new solutions are proposed to fulfil shortages of current solutions. As a proposed solution to the described problem, an experimental point electric heating adaptive control system is proposed and described. Experiment of controlling point electric heating system using pulse-width modulation driven by values of regression analysis and fuzzy logic elements. Adaptive methods allowed to dismiss contact temperature sensors, which is associated with a decrease in the reliability of the system, but this fact is prevented by the use of such control methods that can indirectly determine the required rail heating temperature. Conclusions show that the approach of introducing adaptive methods like pulse-width modulation allows to control point electric heating in more efficient way – using program code, control system will adjust heating by adjusting time intervals when the heating is turned on and off.

“…Intelligent models are also a fairly promising variety of models, but there are a number of disadvantages associated with the difficulty of reproducing nonlinear effects and sensitivity to the quality of training data. This problem is very complicated for several railway systems [6][7][8] and very complicated for marshaling yard with very difficult control and management system in real time [9].…”

The authors of the study work out to determinate of the mathematical model of supercapacitors as an object of an electric traction system capable of providing non-encumbering of obtaining research results and correct reproduction of energy exchange processes in conditions of repeated-short-term modes of traction load operation. In paper, authors make a comparative assessment of six models for the possibility of their integration into the model of electric traction systems with on-board placement of the energy storage.
