This article focuses on the assessment of the efficiency of the modernization of railway wagons intended for passenger transport. The modernization of railway wagons is an important step towards ensuring the safer and more efficient operation of railways. However, this modernization is not without risks and, in addition to its many positive effects, it can also bring new challenges in the form of breakdowns and technical problems. Failures in passenger rail vehicles are a challenge facing manufacturers and transport operators, and identifying the relationships between these failures can help to improve the design, manufacture, and maintenance of these vehicles. Passenger rail vehicle failures can vary in nature, whether mechanical, electrical, or inside the vehicle. This paper attempts to provide a comprehensive view of the effectiveness of passenger rail car retrofitting based on the data collected and statistical analyses. The article further focuses on the description of selected rail passenger wagons, describes the analyses of the statistical data using the correlation between the selected rail wagon failures and their significance, in addition to whether the impact of modernization reduces the number of rail wagon failures. The results of this statistical analysis can be used to better understand the impact of modernization on different aspects of passenger transport and will help in making future investment and policy decisions in this area. © 2017 Elsevier Inc.

Covid-19 has brought about the development of the use of technological applications and initiatives to control the situation. The aim was to effectively monitor and eventually treat patients and facilitate the efforts of medical staff. This paper is the result of research into the possibilities of solving the problems caused by the Covid-19 pandemic by applying selected logistics technologies. The paper provides a new perspective on technologies and discusses possibilities for future research. The goal of the study is based on relevant existing research which examines in detail how five selected technologies can help in the fight against the pandemic. It defines the potential practical application of these technologies in the context of threats to public health. The main findings of this paper concern the application of logistics technologies considering these essential factors. The research characterizes the problems associated with using the proposed technologies, such as costs, time, legislative constraints, safety, and ethics. Proposals for the practical application of logistics technologies in solving pandemic-related problems must accept not only the legal framework but also the socio-ethical dilemmas that these technologies present.

Accelerating rail transport is a key factor in improving the quality of passenger and freight transport. The main research question of the article asks whether it is possible to increase the speed due to the change in the interlocking. The main research tool is a comparison of the interval of crossing before and after the reconstruction of the interlocking. As the entire research is carried out on a single-track line at the Podbrezová station, the interval of crossing is the most relevant indicator. An associated goal of the entire research is to point out a possible increase in the carrying out of station tracks and an overall improvement in the working conditions of operational staff (station inspectors and switchmen).
