The article deals with the issue of access of freight carriers to services in railway stations. With the liberalization of the rail freight market, the number of carriers is gradually increasing. In this situation, infrastructure capacity is often insufficient. Therefore, it is necessary to set the order of access to services in railway stations. The article will use the process of analytical hierarchy as one of many methods of multicriteria analysis. Four important indicators will be selected for carriers: railway stations where the service of stabling tracks can be used, railway stations where rail scales are located, railway stations where it is possible to use the services of a shunting movement from the infrastructure manager, railway stations where the carrier can be using the services of a mobile workshop. At the end of the article, the order of access to these services will be compiled according to the order of importance for railway undertakings. A significant factor will also be an approximate quantification of the performance of individual carriers passing through the selected station.

The last mile is characterized as the last step of delivery to the customer from the logistics point of view. It is necessary to aim and fulfill all customers’ needs mainly during the process of the last mile, because it is directly connected to them. Customer orientation can cause many complications that must be solved according to their will. This part of the supply chain is currently under pressure. Nowadays, trends have changed the last mile into a more ecological process mostly in the transport field. Railway transport is considered as an ecological transport mode therefore the last mile should be done by the railway transport. Preconditions for doing the last mile by the railway transport is the existence of siding (special purpose tracks) at the place of delivery. Our research focuses on minimizing the negative impacts of the last mile to customers in the context of using sidings. This research is based on the real conditions of the Slovak rail network, and on consultation with some experts from freight transport companies.

The paper deals with the analysis of the development of mobile devices and current trends in their use and development. The relevance of the article is in its linking history and present. The article points to milestones in historical development and future trends and development of mobile devices. Today, mobile devices affect all areas of human life, whether private or business. Mobile devices are now able to replace computers and laptops, so the user has the information they always have with them. The development of mobile devices inherently includes systems supporting their functioning, which the article also discusses.

The introduction of tact timetable in rail passenger transport is currently a new evolving trend that increases the efficiency of rail transport. This article seeks to contribute in this area of the issue and thus to raise and improve this system of organizing transport in railway transport. The aim is to propose a methodology that assesses the level of stability of tact timetable based on operational and infrastructural factors. The methodology identifies operational-infrastructural factors that affect the stability and reliability of tact timetable. Using scientific methods, it presents the method of their quantification and determination of the weights of these factors, which evaluate the line sections and transport points of the examined transport path. From a practical point of view, the methodology is generally tact applicable to other European railway networks. In the final part of the work, this methodological procedure is applied in the form of model examples for various transport path.

The effectiveness of regional railway lines has been a much discussed theme recently mainly in case of lines which are not sufficient per the capacity requirements of carriers, or vice-versa, which are utilised only to a minimum extent. The article deals with the assessment of options how to utilise the railway line Hodonín - Holíč nad Moravou with respect to its inclusion into Revision of Transport Expenses document. Based on the analysis of present operation situation in that border crossing as well as on the analysis of passenger and freight railway transport operation various options of utilising the line have been investigated with respect to operation and economic options of individual alternatives.

Research background: The article deals with the study of the dependencies of selected supplementary charges in rail freight transport. In the environment of a globalized society, it is very important that railway undertakings maintain their competitiveness in an open market. The article is part of a case study that deals with the development of pricing. The research was primarily focused on the structure and development of the price of supplementary charges in the years 2004 – 2020 at Železničná Spoločnosť Cargo Slovakia, j. s. c.Purpose of the article: Based on two selected supplementary charges, and the hypothesis of whether or not the development of their price is dependent will be verified by means of regression analysis. The aim of the research is to point out of the disproportionate increase in the prices of supplementary charge, which form a significant part of the calculation of the price for transportation. And for most customers it is a priority for the price of transport.Methods: The article will use a simple regression analysis according to the relationships depending on the type of dependence used (linear, polynomial, ...)Findings & Value added: The results of the research can help to better set the structure of supplementary charges. The goal of the company should be a satisfied customer and a dominant market share.
