The objective of this paper is to present the results of a study compiling a bibliography of railway atlases published worldwide between 1945 and 2021. The atlases are a specific kind of product that supports cartographic communication of information regarding the current or former state of the railway network in a certain area. They are used in professional activities, for travel planning, or as a historical source. The research identified 253 unique titles forming 348 separate volumes. The bibliographic data are presented in tables corresponding to particular geographic regions. The lists are preceded by a descriptive part devoted to the origins of railway cartography, research methods, and a brief overview of selected items.

Decline types of passenger turnover of 517 airports worldwide in 2020 compared to 2019, caused by COVID-19, are analyzed. This decay was uneven in space, as well as in individual countries, areas, poles, centers and cores. The strongest decline in 2020 occurred at airports of Europe (especially in the UK, Spain, Germany, and Italy) and Asia (particularly in India and Malaysia), medium – in the countries of America (the USA, Mexico, Brazil) and Norway, moderate – in Russia, weak – in China. 48% of all airports covered by the study showed a strong decline in passenger turnover (from 65 to 85%), 32% – medium (45 to 65%), 10% – moderate (30 to 45%). A catastrophic decline (over 85%) was recorded at 14 airports (2.7%), weak (15-30%) – in 26 (5%), insignificant (3-15%) – in 9 (1.7%). Stagnation (from -3% to + 3%) was noted only in 1 airport, and growth (more than + 3%) – in 3. The largest international airports with a high proportion of international transit passengers and airports with a narrow resort and tourist specialization were most affected by the covid crisis; less – airports with a dominance of domestic traffic. The pandemic has deformed the persistent territorial structure of world air traffic, which has formed over the past 60 years, and also violated the already established hierarchy of the largest and large airports not only around the world, but also within individual mega-regions and countries with big territories and populations.

The aim of the article was to examine the load on the railway network in Poland with passenger train traffic as at the beginning of 2020 and its comparison with the beginning of 2010. The years 2010-2020 are a period of intense railway investments and the development of regional carriers market. At the same time, the length of the railway network has been shortened. However, the volume of passenger transport and the intensity of train traffic increased, especially in regional traffic. Infrastructural investments and the involvement of local governments improved the railway offers. However, this improvement did not apply to the entire country. It was most visible in the areas of the Warsaw, Wrocław, and Poznań agglomerations, and the weakest in north-eastern Poland. The border of the voivodeship is also unfavorable in this respect. Silesia and Lesser Poland.

Regional passenger rail transport has been affected by changes in the organisation of transport in recent years. This concerns both management issues and the extent of the railway network served. There are noticeable tendencies to reactivate rail connections and to create new transport links. This is related both to service of urban agglomerations and regional transport. The process of creating new railway communication system can be based on: reactivation of inactive tracks or building new connections. The procedure of taking over unused lines by voivodeship self-government is an element of restoring the original railway system. On the one hand it allows to preserve the infrastructure, and on the other hand it may be a solution for improving transport accessibility. It may contribute to reducing the phenomenon of transport exclusion. An additional measure may be the use of bus transport as a feeder to the railway line. The survey carried out has shown that in Dolnośląskie voivodeship 16 sections of railway lines have been taken over and another 5 are planned to be connected to the rail system. Most of the routes are short connecting sections. The study showed that most of the routes are not located in the main planning documents (including the voivodeship transport plan). From the spatial point of view the highest concentration of routes takes place in the southern part of the voivodeship and within the Wrocław agglomeration. The entirety of the local government’s activities should be of a comprehensive nature, and the voivodeship’s regional public transportation system should be the result.

The article presents selected issues of the spatial development of the seaport in Gdynia, in particular its development conditions, as well as the relationship between the port and the city. The seaport and the city of Gdynia are a unique case of development of a port-city unit where, contrary to other cases, the port was created first and then the city started to develop. These conditions had a significant impact on the development of the spatial and economic structure of the port-city complex. The study was supplemented with a synthetic analysis of perspectives and barriers to development of the Port of Gdynia.

In the article, the author returns to the graph methods which were once classic in the transport geography. Using basic indicators such as the cyclomatic number μ, the α Kansky index, the γ Kansky index and the Gns index developed by A. Ciechański, he analyzes the changes in the network of non-urban public bus transport in the area of the Beskid Niski and the Bieszczady Mountains. He also tests the Gns indicator for more complex graphs with a complicated structure, including often very numerous isolated vertices. Unfortunately, unlike the simple and inconsistent transport networks for which it was created, in the case of large transport networks containing many cycles its sensitivity shows a much worse level and the obtained results are much less unambiguous than in the case when the isolated subgraphs are less numerous, but with the more elaborate structure.
