“…By solving the differential equation for the speed under the specified initial conditions (selected ratios k a = t a /T and k t = t t /T, characteristic for this type of drive), the maximum possible speed v and acceleration ω of actuation of the degree of freedom are estimated. The solution to the equation will be expression (1), which establishes a mathematical relationship between the speed v and the course of the degree of mobility S: S=0.5ꞏvt а + vꞏt y + 0.5ꞏvꞏt b (1) Given the ratios:…”

“…Undoubtedly, to some extent, in order to focus attention on resolving issues in the field of coordinating the trouble-free running of trains and reducing the adverse impact of the "human factor" on the established process, a subsequent modernization of the mechanism for the maintenance and repair of cars is required, focused on improving the quality of maintenance service. For this reason, the importance of using diagnostic equipment and nondestructive testing methods in the maintenance of rolling stock is progressing [1].…”

The article discusses the need to improve the efficiency of freight cars operation by introducing modern technologies in the maintenance process. To improve the quality of technical inspection of rolling stock at the maintenance point, it is offered to introduce a robotic complex capable of autonomously conducting technical inspection and diagnostics of rolling stock. Structurally, the robotic complex includes: chassis; manipulator; automation, control and data transmission system; diagnostic equipment; power unit. The possibility of using various diagnostic tools, vision systems, non-contact scanning sensors is considered. The functions of the complex are to pass through the inspection positions, identify malfunctions, accumulate information about the technical condition of the car with the transfer of information to the fleet operator or maintenance point.

“…Moreover, delays in locomotives maintenance will also cause trains demurrage on the main infrastructure; the tariffs for its use is also absent. In this regard, at the stage of transport market formation, the scheme will be effective, if locomotive service centers are located at points, where loading or unloading of train blocks are concentrated [12].…”

Ukraine has undertaken the implementation of European Union Directives, which provide non-discriminatory admission to the railway infrastructure of independent carriers. A significant number of factors considerably affect working conditions of the carriers which are independent of Ukrzaliznytsia. One of the goals while performing transportation by independent carriers is the organization of private locomotives operation and their service by engine crews. The purpose of the article is to assess technical and economic indices of private locomotives use for goods transportation. The schemes of infrastructure objects arrangement for locomotives operation and engine crews work are presented. Performed calculations show the potential possibility of independent railway carriers to fulfil transportation to seaports with the use of its private locomotive infrastructure exclusively. The estimation of economically expedient volumes of cargo transportation by private locomotives in comparison with existing pricing of Ukrzaliznytsia is carried out. The nonlinear dependence of transportation volume depending on the distance is determined, at which the total cost of cargo transportation by Ukrzaliznytsia locomotives is equal to the cost of cargo transportation by private locomotives. The results of the study allow concerned companies to evaluate the investment efficiency into the development of locomotive fleet for rail transportation.

“…This is not always fair. For example, in the paper by Kozachenko, et al [22] the problem of routing empty carriage flows directly from the private sidings of the seaport is solved. At the same time, in this case, despite the significant overall economic effect, the port itself bears additional costs.…”

Purpose. Improving the efficiency of interaction between enterprises that operate public and private railway infrastructure when performing cargo transportation and cargo operations. Methodology. The studies were carried out using the methods of the theory of railway operation and economic and mathematical modeling. Findings. The study found that the transition from a planned economy to a market economy along with increasing customer requirements for the composition and quality of transport services is an objective reason for an increase in carriage downtime at private sidings and junction stations, a shortage of track capacity and shunting locomotives. It is shown that the existing approaches to assessing the effectiveness of the interaction between train tracks of enterprises and mainline railways are aimed at improving the performance of the rolling stock and do not create incentives to solve the problem of the shortage of transfer and processing capacity of the railway infrastructure. Originality. The paper proposes an improved method for assessing the effectiveness of the interaction of participants in the transportation process when performing transportation and cargo operations on the private sidings of industrial enterprises, based on the time the infrastructure is occupied. This approach, unlike the existing one, encourages railways and industrial enterprises to jointly search for the best technological solutions for the use of public and private railway infrastructure. Practical value. The method proposed in the paper for assessing the interaction of participants in the transportation process makes it possible to separate station services in the tariff for the use of the railway infrastructure into separate services of service facilities and track access to them. This will create a competitive environment and encourage participants in the transportation process to use the existing railway infrastructure and develop a new one to obtain a synergistic effect more efficiently.
