Due to the reliability standard set during the design and even when it reaches orexceeds the standard service life of more than 90 % of locomotives, railway transport continues toperform its functions. Many years of experience in the operation of locomotives confirm thecorrectness of the norms laid down in the standards for their design to the design loads andindicators of dynamics and strength of load-bearing structures: the standard stock ratio (2) ensurestheir operation during the service life.(25 ... 30 years) In many countries, as part of the extension of the service life of TRS at onetime had to solve complex scientific and applied problems. For example, most recently in Europeancountries, rolling stock depreciation was up to 65% of service life. In the interaction of TRSproducers and users, the concept of repair and modernization of TRS at the facilities ofmanufacturers was adopted, and the amount of modernization depended on customer requirements.After the modernization of the extension of the service life of TRS, it could be used on certainsections of the railway or in other types of work: economic, export, shunting. In our country, thelong-term operation of the TRS of a small number of series led to the fact that the rolling stock wasalmost not renewed and the problem of extending the service life was not solved. Now difficultpolitical and environmental factors have led to the fact that after some time it will be dangerous touse rail transport. As the world and domestic experience of TRS operation shows, urgent changes inall links of the industry and operation are necessary. The resource of TRS put in production allowsto keep and maneuver in a choice of strategy of management of the maintenance of TRS. Inconnection with the aging of rolling stock and the development of the assigned service life arerelevant to the study of the original and residual resources of the structure. To do this, thestandards must be clarified and supplemented on the basis of accumulated operating experienceand taking into account modern knowledge to assess and ensure the necessary durability and safetyof operation of vehicles. Based on this, the topic of changing the system of extending the service lifeis relevant. The article considers the concept of general approaches to extending the service life oflocomotives.

Currently much attention is paid to the development of the Arctic zone of the Russian Federation. First of all, we are talking about the development of mineral deposits. The peculiarity of these territories is a very low population density, less than 1 person per square kilometer. The living conditions for people there are really not the best. At the same time, without proper transport support for these territories, the development of deposits is impossible. In this regard, the possibility of using "deserted" technologies in all spheres of human life comes to the fore. Today the world is actively developing Big Data technologies that allow you to process large amounts of data. And this means that people can rest and entrust routine operations to a computer. Rail transport looks most advantageous as a transport support for the Arctic zone. The main railway transport systems are railway tracks and rolling stock with integrated systems that ensure the safety of the transport process. The functioning of these systems should be co

The paper based on the analysis of the working conditions of railway transport shows that, ceteris paribus, an increase in actual durability and mean time before failure of rolling stock units is obtained through maintenance of wheelsets, especially during logistic processes on nonmechanized humps. One of the main causes for the service life decrease of wheelsets is brake damage. To eliminate such brake damage on highways, on-board braking dis-tance regulators mounted on the locomotive are used. In the hump yards, using such systems is not possible, since under marshalling, cars are detached from the locomotive. In this regard, an industrial challenge turns up to design a similar in purpose braking distance regulator for humps through skidding. To solve this problem, we developed a method of controlling the speed of cars to be sorted, which complements the widely used technology of the shoe braking and avoids the formation of one-way sliders. The paper presents a skid adjuster, which excludes brake damage to the rolling stock wheels by the slides on the humps using the shoe braking techniques. The motion equation of the rolling stock equipped with a skid adjuster on the hump tracks is developed. In the result of this study, an equation of car motion in the system of “rolling stock Hughes regulator way” allowing to enter the working elements of Hughes controller to an existing and debugged algorithm of any slides with minimal change it.

The article proposes the approach for determining the measure to increase the efficiency of railway transport of the metallurgical plant. The analysis of scientific and normative works on the efficiency of railway transport at industrial enterprises showed that this issue is not fully covered and requires more detailed study. The work of the railway shop of the metallurgical enterprise is considered, namely, the turnover off right cars of different owners and the time of their stay on the factory tracks are determined. An analysis of statistical data was made, which showed that the time difference between the standard set at the enterprise and the actual time of stay of the freight car at the planthas a large discrepancy. This requires spending additional funds for the use of cars of different owners. For this purpose, a model for determining measures to minimize costs at the metallurgical enterprise was developed. The algorithm for its solution involves five stages of calculations. It is based on the model of managements science, which is presented as the approach of linear programming to determine the optimal means of allocating scarce resources in the presence of competing needs. Calculations were made, thanks to which the first stage of development of the model for determining the measure to improve the performance of railway transport was performed and the indicators that characterize it were determined. The total time of rolling stock at the enterprise is determined. Based on this, it is established that it is necessary to separate from the total time the time spent at each station according to the operations performed with the cars. Costs are determined operationally due to the received analysis of the stay and turnover of the freight car at the metallurgical enterprise. Installed stations, which are the most time-consuming freight cars, is there is an excess of payment for the down time of cars at these stations. Based on this, it was decided that it is necessary to study in more detail the operations performed with cars at theses stations and to identify "weaknesses" in the turnover of the freight car at the metallurgical enterprise.

The World

The automotive industry makes a significant contribution to the global economic production. Its annual turnover is comparable to the sixth largest economy in the world. The automotive industry accounts for about 5% of the world Gross Domestic Product (GDP). The automotive industry has a powerful multiplier effect and stimulates the development of a number of other industries. Automotive products account for about half of the world's oil consumption, half of the rubber produced, 25% of glass and about 15% of steel. Note that the size and structure of the automotive market often act as indicators of the level of economic development, and its state quickly and accurately reflects the changes taking place in the world economy.0 The average service life of a car is up to 15-20 years, depending on many factors. The service life is significantly reduced when the car is exposed to aggressive operating conditions. Most often, the car fails due to corrosion damage (corrosion) of its parts: the body, pipelines, elements of brake systems, frames and other important components. The damage caused to humanity by corrosion is enormous. According to various sources, corrosion "eats" from 10 to 25% of the world's iron production. As a result of corrosion of the load-bearing and critical elements of the rolling stock of road transport, reliability and performance, passive safety and road safety are sharply reduced, which requires the use of new effective means and methods to increase the corrosion resistance of critical parts and components of the car. One of the effective solutions to improve the anti - corrosion properties is the application of an insulating coating on the surface of the metal, which can significantly reduce the rate of its corrosion. However, it is necessary to take into account the economic component and the complexity of the technological process. For minibuses of the “GAZEL” family operated in Yerevan, it is of particular importance to increase the corrosion resistance of parts and load-bearing elements of the body.
