The history of the formation and development of railway education in Azerbaijan from the end of the 19th century is considered until the early 1930s; goals, organization and content of the educational process in educational institutions at the railways, forms of educational institutions, problems of training national personnel for the railway industry. It is noted that despite the existing problems in the training of national personnel, primarily related to ignorance of the Russian language, by the end of the 19th century. The first railway engineers from among the Azerbaijanis began to appear.This period of time is associated with important stages in the history of the region, the country and the whole world. If the opening of the first railway line in Azerbaijan was associated with the rapid development of the oil industry, then the expansion took place against the background of the peak of the economic power of the Russian Empire, and subsequently the outbreak of the First World War. A difficult period for the railways of Azerbaijan came after the revolutions of 1917, during the confrontation between the revolutionary forces of the Bolsheviks and local authorities, part of the railways was put out of action. Attempts to rebuild the destroyed tracks were made by the national government of Azerbaijan, but the railway was fully restored only after the establishment of Soviet power in the country.The improvement of educational institutions on the railway is inextricably linked with the development of the railway industry. All historical and political changes that had an impact on the industry were reflected in the process of training specialized personnel.

Currently, the railways of the Russian Federation use high-speed electric trains Sapsan and Allegro, as well as high-speed trains Lastochka and Ivolga.Considered the possibility of replacing foreign-made converter components with domestic-made components.Compared the characteristics and specific indicators of the domestic traction converter BORDLINE CC1500 DC 3kV U 2000 037 A02 and the foreign frequency converter with a 3-level inverter MV9FT-31-781WAD-466+Z. A comparative analysis of the characteristics of the converters shows that the efficiency of the converter of domestic production is higher by 6.6 % with a significant decrease in specific indicators in terms of weight and dimensions.In order to increase the efficiency of the traction converter on the Ivolga electric train, it is proposed to replace it with a frequency converter with a 3-level inverter based on IGBT transistors MV9FT-31-781WAD-466+Z. A diagram of a frequency converter with a 3-level inverter based on IGBT transistors is presented.The weight and size indicators of these converters are the same, which makes it possible to produce this equipment from components of domestic production. The possibility of creating a modern traction converter based on domestic components is shown.Modernization of the traction converter on the Ivolga electric train using the domestic element base will make it possible to bring it into line with modern technical requirements and increase the efficiency of the electric train.
目前，俄罗斯联邦的铁路使用高速电动列车Sapsan和Allegro，以及高速列车Lastochka和Ivolga。考虑用国产元件替代国外变频器元件的可能性。比较了国产牵引变换器BORDLINE CC1500直流3kV U 2000 037 A02与国外带3电平逆变器MV9FT-31-781WAD-466+Z的变频器的特性和具体指标。对转炉特性的比较分析表明，国产转炉的效率提高了6.6%，但在重量和尺寸方面的具体指标明显降低。为了提高Ivolga电动列车牵引变换器的效率，提出采用基于IGBT晶体管MV9FT-31-781WAD-466+Z的3电平逆变器代替变频器。给出了一种基于IGBT晶体管的三电平逆变器变频器的框图。这些转换器的重量和尺寸指标是相同的，这使得可以由国内生产的部件生产该设备。提出了以国产元件为基础研制现代牵引变换器的可能性。使用国产元件基地对Ivolga电动列车上的牵引变换器进行现代化改造，将使其符合现代技术要求，并提高电动列车的效率。

Addressing the history of transport development seems to be an urgent and in-demand task of modern historical science. The study of the historical past of the railway system allows us to understand in more detail the cause-and-effect relationships of their development and to isolate the level of progress that had a serious impact on the further course of history.Studying transport tickets is an important part of studying the history of transport. It becomes possible to understand how, by modifying tickets, they tried to facilitate and speed up the work of cashiers of long-distance buses and railway stations and city transport conductors. Travel tickets, reserved seats, receipts, boarding passes allow you to better study the development of technologies of commercial activity of railways.The article is devoted to the description of a rather rare type of collecting: collecting transport tickets. The history of the appearance of transport documents has been studied: diplomas for the passage of Ancient Rome and roadside payz of China. It tells about the appearance of people collecting transport artifacts and about the dynasties of collectors, provides data on the size of the largest known collection, traces the history of the formation of associations of collectors of transport tickets. The names of the type of collecting in Russian, the appearance of the terms peridromophilia and eisitiristics are considered. It tells about the ways to replenish collections, where and how tickets are searched for or purchased.
