Russian Metropolitan Railway Stations as Historical Architectural Masterpieces

According to the author of the article, the appearance of the first railway stations immediately became the most striking image of the time. The history of the architecture of Russian railway stations begins at the same time when the first railway in Russia was built connecting St. Petersburg to Pavlovsk. Previously existing post stations and the so-called road imperial palaces served prototypes for railway stations.The railway station is, first, a story in which both the most interesting architectural and social plots collide. The railway station offers passengers the most vivid images of our time. The architects who designed the first railway stations had to solve problems that no one had ever encountered before: to cover train sheds by a roof, to design platforms, lighting, ventilation, acoustics... All this made the railway station the most technically enriched architectural genre of its time. And in this sense, the railway station architecture is a very interesting plot, in which everything changes very quickly and where all human relations are very aggravated. Therefore, the railway station is a condensed replica of society. Therefore, at the railway station, you can always very clearly see how society is organised. For example, at imperial railway stations, division of passengers per travel classes was obvious and inherent in the architectural program itself. The imperial pavilions, the imperial rooms also make part of the story... The railway station is, first, an image of modernity, mobility and a history of boundaries between the country and the city. This is especially interesting in the case of metropolitan railway stations.

ANALYSIS OF TECHNICAL AND TECHNOLOGICAL PARAMETERS OF UKRAINIAN PRE-PORT RAILWAY STATIONS

Purpose. The aim of the work is a comprehensive analysis of the technical and technological parameters of pre-port railway stations in Ukraine as key elements of the port infrastructure, ensuring the interaction of railway transport with seaports. Methodology. In the process of research, the methods of analysis and synthesis were used to study the content and the main provisions of scientific publications on the issues of establishing effective interaction between rail and sea transport, with their subsequent comparison and generalization; methods of statistical analysis for research and systematization of technical equipment of port stations. Results. More than 60% of export cargoes go through Ukrainian ports; while 75% of export volumes are delivered to ports by rail. Currently, due to changes in the conditions for the functioning of the economy and the transport system of Ukraine, there is an imbalance between the capacities of ports and the port railway infrastructure for processing freight flows. Based on the analysis, it was found that the throughput of most stations does not correspond to the prospective, and for some stations - and the actual, volumes of work. In particular, for some stations, the capacity of track development is insufficient; a significant problem is also the low efficiency of the shunting means. An effective way to solve the problem of reducing the imbalance in the processing capacity of ports and the pre-port railway infrastructure is public-private partnership in the implementation of appropriate investment projects, the assessment of which should be carried out using modern scientific approaches. Scientific novelty. The authors have systematized the existing technical equipment of the port stations of Ukraine from the point of view of its sufficiency to ensure the existing and prospective volumes of transportation. Practical significance. The results obtained make it possible to provide a scientific basis for further research into assessing the throughput capacity of pre-port railway stations and the effectiveness of infrastructure projects aimed at increasing it.

ENERGY EFFICIENT SOLUTIONS IN INFRASTRUCTURE PROJECTS OF SORTING COMPLEXES OF RAILWAY STATIONS

Purpose. Improving approaches and methods of calculation and design of energy-efficient sorting slides of railway stations, taking into account the mechanization of their braking positions based on the use of modern car moderators, including energy efficient structures. Methodology. The research was performed using the methods of the theory of bitter calculations in combination with the tools of mathematical statistics and probability theory. The assessment of the possible economic effect was carried out taking into account the technical and economic calculations on the criterion of the given savings of annual costs. Results. An estimate of the predicted value of the speed of the very good runner at the entrance to the brake positions when calculating their needs. An adaptive approach to the calculation of the required power of the 1st and 2nd brake positions on the descent part of the sorting slides is proposed. The condition of technological reliability and "survivability" of the system of control of speeds of movement of couplings at rolling down from a sorting hill is checked taking into account action of probabilistic factors. The economic effect of reducing the need for car decelerators for the braking positions of the slides, as well as energy efficiency of sorting complexes. Practical value. The obtained important scientific and practical results to substantiate the reduction of energy consumption and increase the energy efficiency of sorting stations can be used to develop new projects and to survey the parameters of existing sorting complexes, including non-mechanized slides.

FACE MASK DETECTION ALERT SYSTEM

In the present scenario due to Covid-19, there are no efficient face mask detection applications which are now in high demand for transportation means, densely populated areas, residential districts, large-scale manufacturers and other enterprises to ensure safety. This system can therefore be used in real-time applications which require face-mask detection for safety purposes due to the outbreak of Covid-19. This project can be integrated with embedded systems for application in airports, railway stations, offices, schools, and public places to ensure that public safety guidelines are followed. To identify the person on image/video stream wearing face mask or not. If the person doesn’t wear a mask, the notification will be sent to the respected admin with the help of Python and deep learning algorithm by using the Convolutional Neural Network, Keras Framework and OpenCV.

Optimization of Train Energy Cooperation Using Scheduled Service Time Reserve

The main aim of the paper was to develop an innovative approach to the preliminary estimation possibility of train energy cooperation based on data from timetables, without traction calculations. The article points out the need to strive for sustainable and environmentally friendly transport. It was pointed out that rail transport using electric traction is one of the more ecological branches of transport. It also offers a number of possibilities for improving energy efficiency and reducing energy consumption, one of which is the recovery and reuse of energy lost in the electrodynamic braking process. The main ways in which such energy can be used are listed, but the focus is mainly on the aspect of the so-called “energy cooperation” of trains. Then, the current state of the research and knowledge on the narrowed scope of rail traffic management and recuperative braking in rail transportation is presented; an innovative approach to the indirect optimization of the amount of recuperated electrical energy immediately usable by another vehicle by maximizing the duration of energy co-optimization is proposed; and the authors’ function is proposed to enable optimization, taking into account various parameters. The optimization was performed with the use of a proprietary, multi-criteria objective function and the Solver optimization module. Finally, the results obtained using the proposed approach are presented and illustrated with the example of train timetables used by some of the largest railway stations in Poland.

RAILWAYS IN LITHUANIA: FROM TSARIST RUSSIA TO RAIL BALTICA

Lithuania is a transit country. It is a small but significant territory between East and West. This fact is substantiated by the history of the country railways, which started when Tsarist Russia launched the construction of the railway between Saint-Petersburg and Warsaw. There is not much research into the history of railways in Russia, also in Lithuania. Besides, not all available information is reliable due to the nihilistic attitudes towards Tsarism of that time. Only some of the railways in the former Soviet Union were written and talked about. The history of the Lithuania railway is not an exception. Different written sources provide a variety of dates for the first railway to be built in Lithuania. They mirror varied events in the history of Lithuanian railways, thus all of them must be taken into consideration. The article presents the evolution of Lithuanian railway transport from Tsarist Russia to Rail Baltica, which is the European railway project currently implemented in Lithuania. The article discusses the world’s first railways including the ones in Tsarist Russia when the history of Lithuanian railways started. The article also considers the building of the first railway in Lithuania, construction of railway stations, setting the transportation tariffs, selection of railway employees. The author of the article employs historical and online resources as well as a long-standing personal experience in railway transport. The research into Tsar Family’s diaries and historical novels makes it possible to disclose the facts that are not widely known. The author considers the future of Lithuania with reference to the construction of the European railway Rail Baltica. The article would be useful for the readers who are interested in the historical development and future of Lithuanian railways.

Issues of COVID 19 Screening with Machine Learning Algorithm and Data Sets Availability

There is a need to wear a mask during the coronavirus outbreak to efficiently deter the transmission of COVID-19 virus. In these instances, traditional facial screening technologies obsolete for monitoring of group entry at Airports, shopping malls, railway stations, etc. It is, therefore, vital to boost the efficiency of screening. This paper addresses the machine learning algorithm for contactless face screening systems in group participation, social interaction, school management, mall entry management, and market resumption scenarios in the case of COVID- 19. A method to screen entry with masks are developed using machine learning, which depends on various face specimens that were discussed here. The second fold discussion in this paper is that previously there are not many freely accessible masked face-databases. To this end, various forms of masked face data sets are identified, namely MFDD, Real MFRD, and Simulated MFRD. Such data sets became widely accessible to businesses and academics, based on which specific apps may be built on masked faces. The mathematical model, with the code was given. The availability and issues of the above data sets were discussed for the benefit of researchers.
