In the first half of 2020, the global pandemic of the COVID-19 virus became a phenomenon affecting all spheres of human life. Measures against the spread of the virus have led to restrictions in life in public spaces and have also affected the transport sector. These impacts consisted of two types - firstly, the number of connections was reduced due to a drop in transport demand, and secondly, it was necessary to comply with hygiene measures on the part of carriers and passengers. The impacts of these measures could be monitored at all spatial levels, from global to local. This paper deals with the course of the so-called first wave of the pandemic in the Czech Republic in relation to public transport and its organization. The aim of the paper is to provide an overview of these measures in relation to general government regulations and their subsequent implementation at the national, regional (county) and local (selected large cities) level. Furthermore, the paper uses three case studies to show what changes long-distance domestic transport has undergone on selected routes. There was a significant reduction in the number of long-distance connections, some lines were not operated at all, and of course, all cross-border connections were canceled. The paper covers the period from the turn of February and March 2020, when the measures began to take effect, to the end of May 2020, when almost all the adopted measures were gradually relaxed. The paper concludes with a summary of the basic features of the organization of transport during the validity of the special measures, as well as areas where significant changes took place and whose consequences may persist after the pandemic subsides.

The COVID-19 pandemic has affected many aspects of our everyday lives. Governments have taken numerous measures to contain the spread of the pandemic, which has had a direct impact on daily mobility, modal choice and the function of public transport. This study uses quantitative and qualitative data to describe how the pandemic influenced travel on the Prague-Pilsen (Praha-Plzeň) railway line. The results of the case study on the Prague-Pilsen railway line are consistent with experiences in other countries. 38% decrease in passenger numbers was found between 2019 and 2020. Although numbers are increasing again, they still have not reached the pre-pandemic level. The number of connections has also decreased by a third on average (2019 to 2020). We also conducted in-depth interviews with train passengers on the above-mentioned route. Two-thirds of passengers stated that the frequency of their journeys had not been affected by the pandemic. However, like the other participants, they described other changes caused by the pandemic. Fear of infection played an important role, and the inconvenience of overcrowding was mentioned several times. The switch from buses to trains was mentioned, as was the fact that more and more travellers prefer to travel first class. In some cases, changes in the temporality of trips were also documented. The survey suggests that respondents travel less frequently by train for systematic, functional, health or social reasons.
