Purpose. In modern conditions, the problem of increasing the efficiency of the railway transport of industrial enterprises is very urgent, and, first of all, this applies to enterprises of the metallurgical and mining industry, which are the largest recipients and consignors of goods by the railways of Ukraine. In this regard, the purpose of the study is to develop measures to increase the throughput and carrying capacity of the railway infrastructure of a mining enterprise in the context of an increase in the transportation of raw materials. Methods. The analysis of the technical equipment and technology of the railway transport of a large mining and processing plant in Ukraine was carried out using the methods of graphical analytical modeling. Results. The track development of the mining and processing plant ensures the delivery of iron ore from the quarry to the crushing and processing plant. The plant is presented as a system for transporting raw materials from loading points to unloading points, in which the process of its consumption is uniform (unloading ore on the tracks of a crushing plant), and the process of its replenishment is uneven (loading ore at loading points). Smoothing the uneven supply of raw materials between the points of loading and unloading provides the track capacity of the station adjacent to the crushing plant. The carrying capacity of the existing railway infrastructure of the plant does not ensure the mastery of the estimated volumes of transportation of raw materials. Analysis of the results of graphical modeling of the mining and processing plant showed that the limiting elements are the processing capacity of the crushing plant and long distances between the loading points and the abutment station. Organizational and technical solutions are proposed to increase the throughput of the railway infrastructure of the mining and processing plant. Practical significance. The results obtained can be used in the implementation of recommendations aimed at increasing the efficiency of the functioning of the railway transport of the mining and processing plant in conditions of an increase in the volume of transportation of raw materials.

Purpose. The purpose of this article is to study the generally accepted system of transport service, improve the technology of transportation planning and optimize the process of delivery of groupage cargo from the places of their consolidation to end users (enterprises, warehouses, outlets, post offices etc.). Method. When formulating the research task, it is important to take into account the maximum number of the most important factors: the size of the transported consignments; geographical of points of goods storage and loading, as well as end users’ location; type and load capacity of rolling stock; terms of delivery; special conditions for carrying out loading and unloading operations, etc. The problem of determining the optimal route was solved as a travelling salesman's problem using the methods of combinatorial optimization, logistics and some heuristic methods. Results. Researches of various methods of the car route planning for the delivery of groupage cargoes to end consumers were carried out. As a result, the recommendations of the method choice for planning the delivery routes of the goods in different situations were given. Practical significance. Despite the fact that groupage cargoes accounts for a small share of total transport work, but transport costs for them reach a third of all costs. In this regard a rational solution of the routing problem is necessary for effective management of the transportation process and reducing the cost of energy resources in the operation of road transport, which will allow to reduce the transportation costs and improve the economic performance of the whole.

Annotation. The article analyzes the interaction of the main railway and sea transport in modern conditions. A review of new studies and publications in this direction showed that their disadvantage is the lack of a systematic approach and focus on solving only certain organizational issues of interaction. The researches of scientists of the Dnipro University of Railway Transport named after academician V. Lazaryan, characterized by a comprehensive coverage of all problematic issues, are highlighted. Cases of servicing ports by non-public railway stations, in which additional costs of stevedoring companies arise in the absence of a mechanism for their compensation, are highlighted.To obtain an answer to the main research question - the nature of the shortage of receiving-departure and marshalling tracks at railway stations of port railway junctions and the associated delays of wagons waiting for delivery to the port for cargo operations, the work of the Odessa railway junction and the Odessa-Port station serving State Enterprise "Odessa Sea Trade Port".The paper analyzes the technical equipment of the railway infrastructure of the stations of the Odessa junction and formulates a conclusion about the sufficiency of the track development of spans, stations and the throughput of sorting devices. Based on the analysis of the plan for the formation of trains at the junction stations, the organization of work with dispatch routes and container trains, elements of a negative impact on the organization of the work of the port and the Odessa-Port station were identified. These include systemic violations of the train formation plan at the Odessa-Port station, as well as peak loads on the railway infrastructure of the station and cargo devices when servicing railway routes upon arrival and during the formation of dispatch routes and container trains. Inaccuracies in the unified technological process of operation of State Enterprise "OSTP" and the Odessa-Port station were noted when determining shunting locomotives serving the station and the port, which lead to an underestimated number of locomotives and, as a result, additional delays of the rolling stock.The main reason for the disruption of the normal operation of the infrastructure of the railway stations of the Odessa railway junction was established – a systematic violation of the current plan for the formation of trains.As a recommendation for the creation of an operator of the railway infrastructure of the Odessa-Port station and the access road of the State Enterprise "OSTP", the need to improve the draft law of Ukraine "About Railway Transport" was considered in order to create a legislative framework for companies of operators of railway infrastructure similar to European ones.
