The article examines the impact of various types of rolling stock, both retrospective, current, and prospective, on infrastructure objects of railway transport, the study of influencing factors will allow to estimate the scope of work on the restoration of such objects, and this will be the basis for the formation of economic indicators of the production program of transport enterprises construction In this way, it will be possible to influence the economic efficiency of the activities of such enterprises, rationally using their production capacities, taking into account the specifics of the performance of individual works at infrastructure facilities. The purpose of the article is to study the potential for increasing the economic efficiency of transport construction enterprises due to the streamlining and rational long-term planning of the production program of their activities, the main elements of which are the elimination of the accumulated wear and tear of infrastructure objects due to the negative impact of rolling stock of various types during operation. Research methodology involves the use of methods: general scientific methods (abstraction and concretization, induction and deduction, analogy), theoretical research (descent from abstract to concrete), empirical research (comparison, observation), synthesis, analysis, etc. The relevance of solving the scientific problem defined in the article is that JSC "Ukrzaliznytsia" strives to improve the operational indicators of its activity due to the development of the rolling stock fleet and its operational indicators, and the restraining factor is the infrastructure facilities, which according to their technical condition, primarily due to wear and tear, do not allow to use the operational potential to the full extent. It is at this stage that JSC "Ukrzaliznytsia" should pay attention to the efficiency of transport construction enterprises, the purpose of which is to bring the condition of infrastructure facilities to the required operational level. This will allow to optimize the maintenance costs of such facilities and increase the economic efficiency of transport construction enterprises. The results of the study are as follows: the results of the study on determining the main factors affecting the volume and structure of works of transport construction enterprises are presented. The originality and practical value of the research lies in the fact that the article systematizes existing areas of negative impact of rolling stock on infrastructure objects, which directly affects the volume and structure of works of transport construction enterprises, which allows rational management of the economic efficiency of their activities. The conclusions of the study are as follows: the results of the study on the analysis of the impact of rolling stock on infrastructure objects proposed in the work will allow to improve, in the end, the management of the economic efficiency of the activities of transport construction enterprises. The results of the conducted research can be useful for the enterprises of JSC "Ukrzaliznytsia", which, due to their functional purpose, have to perform works on the elimination of wear and tear of infrastructure facilities in order to improve the operational activities of railway transport.Item Definition of Principles of Tourist Traffic Organization on Narrow-Gauge Railways(НВП ПП «Технологічний Центр», Харків, 2017) Bobyl, Volodymyr V.; Martseniuk, Larysa V.; Hnennyi, Oleh M.; Bozhok, Nataliia O.ENG: The article aims are: to design an optimal the classification of narrow-gauge transfers and tourist travels depending on the travel purpose, type of rolling stock, travel term, and the service areas; to determine factors that play main role for the development of tourist traffic on the narrow gauges; to develop a methodological approach that is based on the principle of determining the actual number of passengers and revenues from tourist transportations on the certain routes. The methodical approach to determining the cost of tourist traffic by railway and road transport was further developed. This approach is based on the principle of determining the actual number of passengers and revenues from tourist transportations on the certain routes. It was taken into account the attractiveness of the route, price for tourist vouchers or travel tickets, minimization of the rolling stock number and the cost of construction and income of the company. Moreover, the authors set a goal to develop a methodical approach to determine the costs of the company that will organize transportations on the specific tourist route.Item Determination of Factors Influencing the Development of Tourist Transport(Федеральный центр науки и образования Эвенсис, Нижний Новгород, 2019) Bobyl, Volodymyr V.; Martseniuk, Larysa V.ENG: The article examines the problems of development of tourist transport in modern conditions, discusses ways to solve them.Item Development of P2P Lending in Term of Crisis(Dnipropetrovsk State University of Internal Affairs, Dnipro, Ukraine, 2021) Batmanghlich, Cameron A.; Bobyl, Volodymyr V.; Martseniuk, Larysa V.ENG: The article is devoted to definition content, disadvantages, advantages and features of P2P (person to person) lending under ordinary circumstances and in times of crisis.

The authors used a complex of mathematical models meant for the optimal investment of the processes of creation and use of the railway transport infrastructure. The specific features of these models are as follows: long-term period of realization of the infrastructure projects, many participants with special interests, which do not always coincide, a lot of factors of uncertainty connected with the choice of quantities of the calculation parameters, etc. The authors created economic-mathematical models of the discrete optimal planning of the railway tourism operations. This takes into account conditions of risks and cooperation, and allows to determine sets of effective routes which are most profitable ones, provided they meet the established demands. The latter includes routes which meet maximum criteria of the net costs under the conditions of the established system of demands for the activity of the tourism operators.Item New Paradigm of Railway Passenger(Федеральный центр науки и образования Эвенсис, г.

Тhe authors of the article have set the purpose to determine what the rail hubs are needed for, what conditions are necessary for their construction, what functions the HUBs will perform and what theoretical structure they have. For the first time in Ukraine, we formulated the complex task concerning the organization of railway passenger transfer centres, formulated the refined terminological definition of the rail HUB, with the simultaneous operation of transfers, which will significantly reduce the travel time and improve the comfort. Тo solve this issue, we used a systematic approach allowing to determine the refined terminological definition - the railway HUB, the purpose they are built for, the places of their construction, the main functions and the volume of services rendered. Тhe necessary conditions for the construction of rail HUBs have been determined. Тhe refined terminological definition of the rail HUB and the sphere of rail HUB as a combination of socio-economic relations have been proposed. Тhe transfer variants have been considered. Implementation of the new functions of transport transfer centres (hubs) will allow the management of JSC "Ukrainian Railways" to create additional amenities for passengers and improve the quality of their services by optimizing train schedules, reducing travel time, providing additional transfers for passengers and luggage, as well as shopping and entertainment services.
