DIGITALIZATION SUBSTANTIATION OF TRANSPORT TECHNOLOGICAL PROCESSES IN INDUSTRIAL HUBS AS KEY OBJECTS OF THE CARGO FLOWS ORIGIN
Abstract
The article considers the need for digital transformation of industrial transport hubs as key objects of the origin of mass cargo flows. In conditions of uncertainty, it is possible to parallelly digitize transport technological processes in interacting subsystems (rail and road transport, industrial transport), and a step-by-step sequential integration of these processes on a single digital platform next.

METHOD FOR AUTOMATICALLY CONTROLLING THE SPEED OF A TRAIN USING AN ARTIFICIAL NEURAL NETWORK
Abstract
With the growth of the social economy, the need for transport increases, and the high-speed railway becomes a key element of the transport system. This is not only necessary for the development of the national economy, but also supports the implementation of the national strategy. Therefore, the safety and reliability of a high-speed train directly affect the life and health of passengers, as well as the safety of property. To ensure this, strict control over the automatic operation of a high-speed train during movement is necessary. Currently, research on the automatic control of high-speed trains is at an initial stage. The paper develops an algorithm for automatic control of the movement of a high-speed train using a self-correction strategy based on an artificial neural network for precise speed control.

RESEARCH ON THE RAILWAY BALLAST GRANITE CRUSHED STONE PROPERTIES DEPENDENCE ON THE GRANITE STRUCTURE
Abstract
Based on the research, a structural diagram of granite was compiled and a possible mechanism for the formation of the granite structure, as a structure based on the type of inclusion compounds, was proposed. Direct and inverse relationships have been established between the dependence of the properties of granite crushed stone on the structure of granite, such as strength, abrasion, dissipation, and the influence of the granulometric composition of crushed stone on its strength. The results obtained have practical significance - they should be taken into account when choosing granite crushed stone for the ballast layer of a railway track.

THE EFFECT OF SHAFT ALIGNMENT ON THE ROTARY TURBOMACHINES AND ELECTRIC UNITS ENERGY CHARACTERISTICS
Abstract
Shaft misalignment of electrical units and turbomachinery blades is the cause of premature wear of turbomachinery equipment. In the article the influence of misalignment and misalignment of the turbine unit shaft on the energy characteristics of the rotor machine is investigated. Estimation of the value of misalignment of elastic couplings on operating turbomachines and electric units of traction rolling stock, stationary equipment of power engineering, metallurgy, mine drainage and water supply is carried out. The dependence of additional power losses on the magnitude of the misalignment and misalignment of the shaft axes, as well as changes in force factors caused by elastic deformations of the elements of the coupling couplings of machines, is obtained.

ANALYSIS OF METHODS FOR MONITORING THE TECHNICAL CONDITION OF DIESEL LOCOMOTIVE COOLING SYSTEMS DURING THEIR OPERATION
Abstract
The article provides an overview and analysis of known methods for determining the quantitative component of reducing the efficiency of the cooling device, their advantages and disadvantages are indicated. It is concluded that the condition of most of the operated cooling devices is significantly higher than acceptable values or the complexity of diagnostic measures is unreasonably high. At the moment, there are no reliable monitoring tools for heat dissipation capacity of the locomotive's cooling device diagnostics. The article considers the possibility of creating a comprehensive method for determining the residual reserve of heat dissipation capacity. The sequence of calculation of the methodology is given, in which the coefficient of the ratio of actual and specific heat efficiency is selected as an indicator for assessing the heat dissipation capacity, and the equation of the thermal balance of the coolant is compiled.
