The article attempts to investigate the historical circumstances of the development and serial construction of narrow-gauge electric locomotives at the Dnepropetrovsk Electric Locomotive Plant based on a comprehensive analysis of sources and scientific literature. It is determined that during the 1960s and 1990s the staff of the Special Design and Technology Bureau of the Dnipropetrovsk Plant, having a strong research and production potential, developed and created projects of unique narrow-gauge electric locomotives of PEU 1 series (IELNG1 – industrial narrow-gauge electric locomotive type 1) and PEU 2 (IELNG2 – industrial narrow-gauge electric locomotive type 2) to meet the needs of the Soviet mining industry in the complex mining and geological conditions of Central Asia with modern high-tech electric vehicles. The development of the research and production base of the machine-building enterprise is traced, the production nomenclature of which, originally represented exclusively by electric locomotives and traction units for industrial purposes, was expanded to the production of main traction rolling stock and special repair equipment. It was found that due to the economic crisis of the CIS countries in the first half of the 1990s, the rupture of economic ties of the former Soviet republics and the lack of need for such equipment on electrified access roads of narrow-gauge Ukrainian mining enterprises all work on designing promising projects and serial production of narrow-gauge electric locomotives at the Dnipropetrovsk Electric Locomotive Plant were stopped, and the Special Design and Technology Bureau of the enterprise, having received a state order, was reorganized into the Ukrainian Research Design Institute of Electric Locomotive Construction and focused on the development of main wide-gauge locomotive fleet of the railway network of Ukraine. Despite the fact that the Ukrainian Research Design Institute of Electric Locomotive has been liquidated and the Dnipropetrovsk plant is in decline, taking into account the historical experience of electric locomotive building in Ukraine is of fundamental importance in the general perspective of Ukrainian transport engineering and the domestic railway industry in particular. Further study of the history of Dnipropetrovsk Electric Locomotive Plant requires analysis of the historical circumstances of the institutionalization of the Special Design and Technology Bureau of the enterprise from the creation of shunting electric locomotives and traction units for industrial purposes to the development and re-equipment of main traction rolling stock and specialized repair equipment within the state enterprise «Ukrainian Research Design Institute of Electric Locomotive Engineering» under the leadership of Academician Victor Bratash.

In the article on the basis of the complex analysis of sources and scientific literature the attempt to investigate historical circumstances of development and construction of shunting electric locomotives at the Dnipropetrovsk electric locomotive plant has been made. It was found that during the 1960s and 1970s, the team of designers of the Dnipropetrovsk plant, having strong research and production potential, at the request of the Ministry of Railways of the USSR developed and built unique samples of shunting electric locomotives of the VL41 and VL26 series to meet the needs of Soviet main-line railways with modern high-tech electric vehicles. It is proved that in the absence of thorough experience and, accordingly, the possibility of a rapid technological breakthrough in the development of main-line locomotives, during the experimental operation of shunting electric locomotives VL41 and VL26, several design shortcomings were identified, which led to their further use exclusively on the house tracks of enterprises, and designers of Dnipropetrovsk plant later focused on the development and construction of traction units for industrial application commissioned by the Ministry of Ferrous Metallurgy of the USSR. At the same time, the construction of the main-line railway equipment to the order of the Ministry of Railways allowed the staff of the enterprise to gain valuable experience, which was later used in the implementation of the renewal program of rolling stock of Ukrzaliznytsia. Although today the Dnipropetrovsk plant is in decline, the analysis of historical circumstances of formation and design and technological heritage of electric locomotive construction in Ukraine is of fundamental importance both in the general perspective of the development of domestic transport engineering, and the railway industry in particular. Further study of the history of Dnipropetrovsk electric locomotive plant requires clarification of the historical circumstances of institutionalization of the Special Design and Technology Bureau of the enterprise from the creation of industrial electric locomotives and traction units to the development and re-equipment of main traction rolling stock and specialized repair equipment within the state enterprise “Ukrainian Research Design Institute of Electric Locomotive Engineering”.

Train Speed

ter reaching the maximum voltage at the 4th control zone of the rectifier-inverter converter of an AC electric locomotive, a further increase in speed is achieved by connecting the field attenuation system (FA) of traction electric motors (TEM). All domestic electric locomotives use the FA TEM system of the inductively active type with step switching. However, it has drawbacks, one of them is that step switching causes speed losses and slows down the acceleration of electric rolling stock (ERS). By 2025, the goal is to increase the speed of freight trains, which will increase freight turnover on the railway network [1]. One solution is to improve the ERS. In this regard, it is proposed to improve the standard FA TEM system of an electric locomotive by using IGBT transistors, which allow smooth regulation of the excitation current. In the article, using the graphical method of the RM, a curve of the train speed is constructed, which proves that the smooth control of the electric locomotive FA TEM allows you to quickly reach the maximum permissible speed of the electric locomotive on the section and to move at a higher speed in the ascent than with step-by-step regulation. The simulation of the 3ES5K series electric locomotive in the «Cortes» software complex on the Winter - Irkutsk-Sortirovochny section was also carried out, which proved that with the smooth regulation of the FA TEM, the technical speed of the ERS increases by at least 2,5 km/h.

Specificity of operating conditions of the rolling stock defines a number of requirements for lubricants intended for the wheel-rail tribosystem. Lubricants are used for “wheel — rail” contact, the aggregate state of which varies from liquid to solid. When evaluating the lubrication properties of these materials, a significant number of factors must be taken into account, in particular, influence of the environment, method of application, condition of the rail surface. The paper discusses the main operational requirements for lubricants operating in a wheel-rail tribosystem. Temperature ranges of the lubricants used for the “wheel — rail” contact on the railway network of the Russian Federation are given. As a result of the research, it was determined that none of the materials used for lubrication of the wheel-rail system satisfies the operating temperature conditions of the traction rolling stock.  To solve this problem a lubricant was developed and tested in an industrial environment at the Rostov State University of Railway Transport. Its lubricant composition allows to significantly expand the temperature range of the lubricant. Complex of experimental studies and method of orthogonal central composite plan of the 2nd order established the optimum values of the thickness of the working shell of the 0.846 mm lubricating rod and the 50.411 % percentage of plastic lubricant, allowing to extend the temperature range of lubricant rods and, in particular, completely eliminate the lubricant flow to achieve a temperature of 126.034 °C. Proposed composition of the lubricant was tested on a freight electric locomotive of the VL80T series, equipped with non-power lubricators, under the conditions of the Bataysk — Likhaya section of the North Caucasus Railway. Intensity of wear of the wheel flanges of the traction rolling stock lubricated by the proposed material, compared with the intensity of wear of the wheel flanges without the use of lubrication systems is reduced by 2 times.
