The article reviews the world experience in the construction and operation of high-speed railways in terms of factors that determine the success or failure of such projects. Since the construction of HSR is often considered as a part of national projects on a broader scale, it is proposed to use as criteria for success not only commercial indicators, but also various socio-economic effects arising from their implementation.

The author classifies externalities that reflect the impact of HSR on the development of regions and cities and presents the results of foreign research on their quantitative and qualitative analysis.

Special attention is paid to the experience of China, since this country significantly differs from the rest of the world in terms of development of high-speed rail traffic. In this regard, the largest amount of representative data that allows us to identify the success factors of HSR projects can be found for Chinese projects.

The main scientific result of this article is a generalization of the existing experience of HSR construction projects and justification of the prospects for implementing such projects in the Russian Federation.

This article describes how to improve the organization's internal control system by means of tax monitoring carried out in JSC "Russian Railways" with direct access to the company's information systems in real time for tax officers.

Background: The problemto reduce the metal content of the levitation track is important when we create the transport systems with magnetic suspension.

Aim is develop the reasonable recommendations to choose the geometric dimensions of the levitation track.

Methods: we usedthe main provisions of the electromagnetic field theory and the aspects of the Fourier theory.

Results: the optimal values of the width and thickness of the levitation track are justified.

Conclusion: when we choose the width of the track we should be guided by considerations related to material consumption and the appearance of the side electromagnetic forces. The values of these forces are bigger the greater the ratio of the transverse displacement of the excitation solenoid to the track width. From the point of view of electrodynamics the value of the order of several centimeters we can consider as the upper limit of the track thickness.

Background: The article describes the rationale for reducing the metal content of platform cars of a modular electric freight train (MEFT) due to the distribution of traction power across the composition and reducing internal kinetic forces in the train. The calculation of the volumetric model of the car frame under the action of the weight of containers and quasi-static load, the analysis of the distribution of equivalent stresses is made. The effects of introducing these types of wagons into modular electric freight trains are considered.

A railway train of locomotive traction is a complex mechanical system in which dynamic processes occur due to the traction force of locomotives, fractures of the profile and track plan, braking and releasing the brakes, different rates of pressure change in the brake line, and uneven resistance to movement of the locomotive and cars [1]. When driving the MEFT formed a much smaller amount of internal kinetic energy, allowing to reduce the load limit on the hitch and the frame of the wagons to transport more cargo with equal traction power by reducing the coefficient of tare of the train. In addition, running MEFT will improve the handling and safety of trains, reduce operating costs for passing train flows by reducing energy consumption for traction, braking, reduce the time for testing the brakes, the number of car, locomotive and crew hours. We predict significant (up to 7 times) reduction of loads on the coupling devices and the frame of cars, if the strength condition is met.

Aim: To justify the possibility of reducing the loads on the auto-coupling equipment and metal structures of the frame of platform cars as part of modular electric freight trains by reducing the longitudinal forces in the auto-coupling devices due to the distribution of traction power across the composition.

Methods:

• special engineering methods for traction calculations applied to railway transport;
• engineering and technical methods of calculation and design of platform cars;
• finite element method;
• a system method that allows you to identify various direct and indirect relationships in the analysis of the selection of frame structures of platform cars.

Results: We  justified  reduction of loads on auto-coupling devices and load-bearing frames of platform cars in MEFT. It is revealed that the decrease of axial compressive loads on the automatic coupler device with 2,500 kN in the car locomotive hauling up to 400 kN at the car the IAEG will help to alleviate the weight of the metal frame of the wagon-platform for transportation of containers and reduce packaging of the car is 1.6 t, by 7.3 %. The reduction in the cost of the car will be 76.8 thousand rubles, or 3.84 %.

Conclusions: The author offers a justification for reducing the weight of container cars-platforms of a modular electric freight train, on the basis of which it is possible to reduce the metal content of cars and transport a larger amount of cargo with equal traction power in comparison with a train of locomotive (concentrated) traction.

Background: In the domestic market, the consumption of fuel oil increases during the winter period, leading to higher prices. At the same time, the cost of inputs and the time for the discharge of viscous oil products are greatly increased. The duration of the discharge process is related to the physico-chemical properties of the fuel oil. Its viscosity depends on the temperature of the product itself and the temperature of the environment, which in our country averages –5.5 ºC per year.

Aim: Reduction in the length and cost of transport of viscous petroleum products.

Methods: The article proposes a new method for the carriage of viscous petroleum products by rail, ensuring that their fluidity is preserved without the use of thermal insulation of the boiler of the tank-wagon and the means for carrying the heating. Simulation models of the processes of pouring out viscous petroleum products for a traditional and new method of pouring in the circulation method of discharge of viscous petroleum products, which make it possible to estimate the quantity of resources consumed, are constructed.

Results: The work shows the peculiarities of the existing process of discharging viscous petroleum products. Simulation and functional-cost analysis of the discharge process were carried out under the circulatory method for heating viscous petroleum products. The results were compared.

Conclusion: In the new pouring method, the discharge process is similar to the summer period.

Rationale: The Russian transport system is losing its competitive advantage due to the slow response to digital calls. Thus, for subjects of the market of transport and logistics services, it is relevant to have recommendations for adapting a business model when moving from an analogue economy to a digital one.

Purpose: To develop a conceptual diagram of the digital transformation of the business model of the operator company.

Methods:

• сomparison of the principles of the five business areas of the operator before and after the transition to the digital economy;
• analysis of the behavior of companies in the transport market;
• summarizing the results of the study and assessing the possibility of their application to other organizations in this market segment;
• case method – “Development of measures for the effective development of multimodal transportation of the Asia-Pacific Region” (INTERTRAN));
• an integrated approach is the search for new points (channels) of interaction with a dynamic network of customers through the implementation of industrial logistics projects.

Results:

• the status of five areas of the business strategy of the operator company was determined before and after the transition from the analogue era to the digital one;
• the conditions are formulated under which the implementation of the business process "sale of transport and logistics services" will provide the sales department of the operator company to develop "proactive sales";
• recommendations are proposed for adapting a value proposition for the provision of transport and logistics services.

 Conclusions: The novelty of the proposed conceptual scheme for adapting the business model of the operator company during the transition from the analogue economy to the digital one lies in the initial definition of the stage of digital transformation of each of the five areas of the operator’s business strategy, and then in the selection of a specific digital technology for implementation in a specific business-process.
