Opis:
Ensuring safety of railway traffic is one of the most important goals of every state. All incidents connected with security that take place in the networks of railway lines result in taking actions aimed at elimination of similar situations in the future. The elements affecting security of the railway system include: technical condition of railway infrastructure and rolling stock, applicable law, people, that is, professional qualifications and proper performance of tasks by the workers. The authors formulated the following research problem: what are the strengths of railway security, and what should be improved? The methodology of qualitative analysis was applied. The survey research on the level of security and diagnostics of causes, needs and options of improvement of security in rail transport were conducted. Broad analysis and inference were conducted. The directions of improvement of security in supervisory, technical, organizational and operational terms in railway transport were presented in this article.

Opis:
The paper analyses the legal definition of railway areas in Poland based on the Railway Transport Act. The author tries to find an answer to the question of what the legal status of railway areas in the Polish legal system is, with emphasis on the classification of railway areas to the wider group of special areas. Moreover, the paper describes the restrictions on investments on railway areas which are presented based on the previous judicature of the Polish administrative courts. Then other detailed obligations resulting from the special legal regime in this area are explained.

Opis:
Determining the course of a railway track axis using satellite methods relies on ensuring the precise assembly of GNSS receivers in dedicated measuring devices. Depending on the number of receivers, solutions that are based on placing the apparatus directly above the railway track axis (as well as in eccentric positions) are used to indirectly obtain data to form the basis of the desired results. This publication describes the installation of five GNSS receivers on a mobile measuring platform as part of the InnoSatTrack project. The methodology and the procedure of the geodetic measurements required to obtain the geometrical configuration of the measuring apparatus, specified in the technical project, are presented. The publication presents the principles of total station measurement methods as well as the steps taken to achieve precise results from staking out. The process of acquiring the same configuration of the GNSS receivers, based on the geometry of the squares on the two measuring platforms that were used in the research, has been shown. The final determination of the position of the receivers did not exceed an error of 0.010 m with an average error of 0.003 m, despite the occurrence of mounting difficulties. The results have demonstrated the high credibility and effectiveness of the presented solution.

Opis:
Modernization or revitalization of a railway line involves the necessity of reconstruction or renovation of practically all the engineering objects and constructions on its premises. While, in the case of objects, not protected by the Historic Preservation Maintenance of City-Owned Buildings, the situation is relatively easy, in the case of historical buildings, the scope of possible construction works can be significantly reduced. On the example of the modernization of the Wroclaw Główny railway station track system, the use of modern slab track is presented, whose aim is to obtain the required performance parameters of the engineering structures (old boreholes) located in its area. The non-skid surfaces used are ERS - rails in the cover and block rails of the EBS type. The use of pavement-free pavements allowed the historic bays to be preserved. Their main girders are made of riveted baffles, without interfering with their historical material. The presented solutions can also be used for the modernization of different types of engineering objects and construction, not necessarily recorded in the register or records of historical monuments - for example, in riveted constructions of those of or unique shape, located on lower category railway lines. It gives opportunity to preserve and continue to use old objects, exposing their beauty and technology, currently not used (for example riveting).

Opis:
Dynamic behavior of a track-train system is a function of axle loads and support stiffness because of non-linear supports. Therefore, it is expected that the support stiffness affects the behavior of the railway track during passing of a light or heavy car body. Since the effects of axle loads caused by light and heavy railway vehicles and support stiffness of ballasted railway tracks due to passing railway vehicles have not been studied adequately, therefore the present study focused on this issue. For this purpose, this issue was first investigated by passing a light and heavy car body including bogies with three axle loads as field tests. Then, numerical analyses of the railway track caused by the passing of these railway vehicles were studied, and the numerical results were compared with the field results. There was a good agreement between the values of field responses and numerical analyses. Subsequently, a series of sensitivity analyses on effects of the axle loads caused by light or heavy loading and support conditions was done on the ballasted railway track. The results indicated that the maximum vertical displacements increased by axle loads, increased sleeper distances and decreases support stiffness. Finally, equations of track behavior based on support stiffness and axle loads were derived.

The article presents selected results of thermovision measurements of EOR elements used for heating railway turnouts under the BRIK2/0036/2022 project. The tests were carried out for various types of railway turnouts (ordinary). The results made it possible to observe the temperature distribution for different construction solutions of turnouts. Further work is focused on preparing assumptions and criteria for developing an application supporting the interpretation of thermo-grams, which can be a tool supporting the diagnostics of EOR devices. The creation of a simple diagnostic tool that allows the evaluation and interpretation of the obtained thermogram may enable maintenance services to make the right decisions in the field of operation.
