The automation of control systems for life support processes and the provision of services at the infrastructure facilities of the passenger complex is considered. Digitization of borders, technologies, technical, technological and organizational processes involved in the provision of services for passengers, in the operation of station complexes, will make it possible to effectively manage engineering networks, minimizing gaps in the infrastructure and processes of transport systems.Causal relationships, algorithmization, mapping, data analysis, block diagramming, modeling, etc. are used. The main projects for the digital transformation of passenger facilities are identified, examples of local automated control systems for the life support processes of the station complex are given.The issue of automating feedback from passengers has been worked out separately, at the station complex, thanks to the information and reference telephone service, issues of a sanitary nature are centrally resolved. The proposed developments will make it possible to justify the development of technological areas within the frame-work of the Digital Railway program and the gradual transition from manual (personalized) labor at the station complex to an automated system during the modernization, reconstruction or introduction of local digital objects related to passenger service. As a result of these activities, it is expected to achieve the maximum efficiency of life support processes and the processes of rendering services of vault complexes.

Digital technologies are reshaping many branches of transport, logistics, including the learning process. Digitalization is considered as the use of digital technologies to update and diversify the learning process. The training center is a mock-up of a railway consisting of ten stations, where the workplaces of the operational staff of the organization of train traffic are organized, two levels of traffic control are implemented: station and dispatcher. The layout has many objects and affects many railway transport technologies. The article discusses the creation of a digital ecosystem of the “B.P. Beshchev Training Center Traffic Control”, for this purpose the following tasks are solved: systematization of information about the objects of the training center; placement of information on University resources; providing open access to information via direct links. This will make it possible to organize the educational process in a new way, students will instantly have access to information about the objects and work that they need to organize in business games and laboratory work. It is proposed to use already well-known digital solutions, such as the classification of educational center facilities, the use of an “Information and Educational Environment”, as well as direct links when using modern mobile devices using QR codes.

Over the past two years, due to the spread of the epidemic and the restrictions imposed, state borders have been closed, restrictions on the movement of people and goods have been established, supply chains have been disrupted and, as a result, consumer demand and purchasing power have decreased. These events had a negative impact on the revenues of operator companies. Transportation of goods is carried out by different modes of transport. The choice of transport depends on many factors: the volume of cargo transported, the location of enterprises of producers and consumers, the degree of development of the transport infrastructure.At present, the task of reducing the transport component in the price of goods and, accordingly, the costs of operating companies of railway rolling stock during the transportation of goods is becoming urgent. This can be achieved by outsourcing some of the work performed by rolling stock operating companies.The conditions for the termination of work by the rolling stock operator are considered. A tool for analysis is presented, an assessment of the effectiveness of outsourcing is made. The use of outsourcing will allow railway rolling stock operators to reduce costs for non-core activities, to focus on those processes that directly bring profit.

The main task of the transport system is the most complete satisfaction of the needs of business entities and the population in transportation, reducing the time of delivery of goods and transportation of passengers on the basis of a qualitative increase in the capacity of the entire transport system. This problem is solved with the help of computer technology and new information technologies in transport management systems. The most demanded is the database technology implemented in modern automated transport management information systems. Given the exponential growth in the volume of databases used, strict time limits for real-time management decisions in transport management systems, the task of minimizing the time to execute information queries in the database is of particular relevance. The execution time of information requests is infl uenced by the methods of physical storage of databases. To solve the problem of minimizing the execution time of information requests, it is necessary to determine the physical parameters that affect the efficiency of database processing. An external memory simulation model is described for optimizing the physical parameters of database organization, based on the exchange procedures implemented in modern database management systems between external and operational memory upon information requests. As a key optimization parameter, a memory block reservation factor is substantiated, which allows minimizing the number of slow accesses to external memory. The rationality and adequacy of the proposed model in the process of research is confirmed by the results of simulation modeling.

The development of an ultrasonic fl aw detector receiving unit for rail monitoring includes theoretical and practical studies. Special attention is paid to the experimental determination of the characteristics of the ultrasonic piezoelectric sensor and the description of the receiving-amplifying path. A mock-up sample of an ultrasonic fl aw detector allows checking rails for defects and gives a tangible gain in dimensions compared to bulky analogues.The theoretical methods used were based on the principles of electrical engineering, electronic engineering, graphical analysis and the theory of automatic control.Experimental studies of the piezoelectric sensor allowed us to determine its main resonant frequency. The correct choice of parameters of the amplifier unit ensured accurate and reliable operation of the device. Practical tests of the fl aw detector using a special buffer sample of the rail made it possible to adjust its sensitivityThe input amplifier of the microvoltmeter V3-40 is taken as the basis of the receiving and amplifying path of the fl aw detector. The device includes the possibility of its use in conjunction with the converter. The structural diagram of the fl aw detector is presented. The electrical circuit of the input divider with the selection of the necessary resistances and the electrical circuit of the effective value meter with a description of all its elements are described.Operating modes and electronic circuits are selected according to reference data, taking into account their high reliability of operation. The use of analog integrated circuits in the circuit solution made it possible to increase the reliability and accuracy of the fl aw detector device, simplify its adjustment, reduce zero drift and improve the quality of the output signal.
