This paper deals with the evaluation of the level of detail and depth of the simulation model on the resulting accuracy of the simulation and its time intensity. Using the import of infrastructure data, various models of the same regional line were created in variants according to the accuracy of the entered data. Based on a comparison with the movement of a real vehicle, a level of detail was determined that does not affect the results of the simulation from the perspective of the carrier or the customer. The results of this research will help in the preparation of simulation models of more complex parts of the network.

This paper deals with railway lines with low traffic intensity where trains are operated under simplified conditions. Those conditions are stated in a regulation, and there is no interlocking system on the line. The whole railway operation is organized according to a regulation in cooperation with the train crew. For the calculation of the throughput, we can use analytic or simulation methods. On those lines there is a big problem with the common working methods because of special circumstances on each line, which are influencing the technological times and reliability of the calculation. The simplified conditions are the transforming of regular interlocking systems on the administrative level. Therefore, it is very complicated to use a common simulation model. Most of the simulation tools are not able to work with it. The motivation of this paper is to prove that modern simulation tools are usable for that specific condition as well. The simulation model was built in SW OpenTrack which is able to modify its functions to figure out each technological action to ensure the correct function of the model. This functionality is described in the paper in general and implemented on a case study.

Using simulation in OpenTrack, this paper analyses the journey of type trainsets on model infrastructure in the line section Rokycany–Ejpovice–Plzeň hl. n. The aim of this paper is to assess the efficiency of increasing the track speed in this section. Analyzing the output characteristics of the simulation, selected indicators were assessed which influence the efficiency of further increases in track speed. One of the simulation scenarios is using the European Train Control System Level 2 (ETCS L2) system as the necessary condition of the speed over 160 km·h−1.

In the paper, the present state of scientific knowledge in authorising the types of railway vehicles in Slovakia and abroad is analysed by the authors. The aim of the authorisation of the types of railway vehicles is to take into account the interests of the whole society in the field of transport in the manufacturing of these vehicles or their import from abroad. These interests mainly include a greater security of transport, as well as a greater quality, reliability and lifespan of railway vehicles. The authors also analyse the Commission Recommendation 2014/897/EU of 5 December 2014 on matters related to the placing in service and use of structural subsystems and vehicles under Directives 2008/57/EC and 2004/49/EC of the European Parliament and of the Council, which should contain instructions related to the matters in question. At the same time, it is necessary to take into account Directive (EU) 2016/797 of the European Parliament and of the Council of 11 May 2016 on the interoperability of the rail system within the European Union, and Directive (EU) 2016/798 of the European Parliament and of the Council of 11 May 2016 on the railway safety. In addition to ensuring the applicability of interoperability regulations (new directives, regulations, decisions, recommendations, etc.), the aim of this paper is to present a methodology of authorising the types of railway vehicles and a software model (SW) of authorising the types of railway vehicles, with European legislation as a possible tool to speed up and simplify the entire process. The paper is concluded by three types of authorisation processes for different railway vehicles and their accessories, comparing the length and complexity of processing using the standard authorisation process and using the SW tool proposed.

The gradual liberalization of the Czech rail market did not leave unaffected sidings and railway infrastructure managers operating railway transport as their main business activity at the same time. This paper presents the main changes in capacity allocation on public sidings in accordance with the amendment to the Act on Rail Systems. It outlines the specific procedures in capacity allocation on public sidings, the specific modes of request processing and the economic side of capacity allocation. The purpose of capacity allocation is to allow for an efficient use of services offered to all authorized entities. The requests are generally submitted through PROK SW. Furthermore, this paper touches on the initial experience of the Faculty of Transport Engineering of the University of Pardubice, as a capacity allocator on public sidings and rails owned by České dráhy, a.s., with statistical evaluation.

Simulation modelling is one way to determine the capacity of railway lines. The specialized software tool OpenTrack was used for simulation. The aim of this paper was to find out whether the OpenTrack simulation software can be used for the calculation of headway, and to compare the results with the methodology of the Railway Infrastructure Administration (SŽDC). Using the software tool, a detailed transport network model can be created including all its important characteristics. The simulation follows the movements and behaviour of trains with predefined parameters on the modelled railway line. OpenTrack allows for monitoring a range of parameters including not only train delays, train conflicts and train traffic flow, but also for instance train energy performance and headways. During the first stage of work with OpenTrack, a simulation model was created, not reflecting any existing infrastructure but including parameters typical of railway lines in the Czech Republic, such as the configuration of gridirons, length of station tracks, size of block sections, etc. This model was subsequently used for the simulation of type train set journeys, and a headway calculator was used for the calculation of headway values. These values were compared with the methodology used by the Railway Infrastructure Administration. The paper is concluded by the comparison of the above mentioned approaches.

The article discusses the change of siding technology for a fossil fuel power plant using a new reloading system of Innofreight containers. This is a modern system for transporting thermal coal in special transport units – Innofreight containers. The assessment of the new technology takes into account not only technical, but above all technological and economic changes and benefits. There was an analysis of the current situation and it was decided to introduce the new technology of Innofreight system. Its implementation brought additional investment in treatment of industrial tracks for loading, the construction of transshipment facilities for containers, CCTV installation, and a higher degree of security equipment.
