Observed growing changes in the character and severity of the risks in rail traffic safety and rail transport security are associated with present development of utilized technical solutions. New hazards are coming out, besides known ones, including hazards associated with cyber-crime. As a result it is fully justified to undertake works dedicated to collect and settle all risks associated with technical solutions using modern technologies for acquisition, computing and transfer of the data, which are vital from the rail traffic safety and rail transport security point of view. Article defines rail transport systems safety, security and cybersecurity functional integrity levels thanks to knock-out and differentiating questions regarding identified key safety related functionalities. Proposed methodology was used for safety and security verification of a chosen homogenous rail transport system separated from the overall Polish railway system. Results have shown discrepancies in utilized protection measures. Proposed methodology can be used for assessment of existing systems as well as for specifying scopes of investments both for infrastructure and rolling stock modernizations. Applicability range covers railway transport, light rail services, metro, urban rail transport systems as well as rail based transport systems using autonomous vehicles.

Abstract The issue of operative data reception on location and movement of railcars is significant the constantly growing requirements of the provision of timely and safe transportation. The technical solution for efficiency improvement of data collection on rail rolling stock is the implementation of an identification system. Nowadays, there are several such systems, distinguished in working principle. In the authors’ opinion, the most promising for rail transportation is the RFID technology, proposing the equipping of the railway tracks by the stationary points of data reading (RFID readers) from the onboard sensors on the railcars. However, regardless of a specific type and manufacturer of these systems, their implementation is affiliated with the significant financing costs for large, industrial, rail transport systems, owning the extensive network of special railway tracks with a large number of stations and loading areas. To reduce the investment costs for creation, the identification system of rolling stock on the special railway tracks of industrial enterprises has developed the method based on the idea of priority installation of the RFID readers on railway hauls, where rail traffic volumes are uneven in structure and power, parameters of which is difficult or impossible to predict on the basis of existing data in an information system. To select the optimal locations of RFID readers, the mathematical model of the staged installation of such readers has developed depending on the non-uniformity value of rail traffic volumes, passing through the specific railway hauls. As a result of that approach, installation of the numerous RFID readers at all station tracks and loading areas of industrial railway stations might be not necessary,which reduces the total cost of the rolling stock identification and the implementation of the method for optimal management of transportation process.

The article discusses the issues of implementation and organization of high-speed transport. The objective of the article is to consider possible options for implementing highspeed (HS) motion systems using the principle of magnetic levitation, which will ensure high speeds for delivery of goods and carrying people over long distances. To achieve this objective, it is necessary to develop an engine and technical solutions for design of HS rolling stock, make decisions on energy supply infrastructure and the HS track, address safety issues and new control systems considering the state of the infrastructure and its design elements. The article discusses several options for implementation of high-speed transport systems, differing in the power supply system, current collection and track based on the magnetic levitation approach. An original approach is proposed in implementation of magnetic levitation transport using the technology of electromagnetic guns designed to implement traction forces of a magnetic levitation vehicle. The advantage of this approach is that it opens the possibility of maneuvering for the vehicle while driving. This allows to abandon switch turnouts, now significantly limiting the use of magnetic levitation transport. A mathematical model describing interaction of an electromagnetic gun and supermagnets located on the track is considered. In constructing the model, methods of the theory of electromagnetic field and interaction of magnetic bodies were used, and when constructing a model of interaction of rolling stock with a magnetic track, methods of mathematical algebra and the Cauchy theorem were used. The article discusses various principles of organization of movement using the magnetic levitation for urban, suburban, and intercity transport.

The contemporary literature of the subject lacks explicit determination of the role performed in rail transport systems by certain major components and assemblies used in rail transportation. One typically perceives the technical solutions applied in railway engineering as an entire body of solutions or as a subsystem, without properly emphasising the impact of defects on the operating efficiency of the rail transport system and without the due regard to safety in this domain of transport. The switch point mechanism/switch point assembly is an important component of a rail transport system. This article is an attempt to identify the role and importance of this assembly in a rail transport system.

AbstractTransport telematics systems integrate information technology with telecommunications for their use in various transport systems. Thanks to the use of advanced technical solutions and modern telecommunications and IT systems, it is possible to implement additional innovative services. They can be used to rationalize the process of using and maintaining means of transport. Modern vehicles are equipped with telematic on-board systems. Such solutions combine various electronic devices used in the vehicle. For this purpose, bus solutions are used, thanks to which it is possible to control individual systems and devices. It is also possible to use the transmitted data to detect negative exploitation phenomena during vehicle use (e.g. glazing phenomenon, work in the upper engine rev range with too low coolant temperature, intensive work compressor of the high air pressure system being a symptom of inability of pneumatic systems). This is possible because the data being sent has a specific information resource. Thanks to this, to can be concluded about the loss of the exploitation potential of the vehicle. This approach will be used to rationalize the technical service of the vehicle fleet, with regard to profiling. Using exploitation data, received via a telematic interface from vehicles, it is possible to profile the rolling stock. It consists in distinguishing individual sets of vehicles due to certain reliability and exploitation properties. This approach allows for the specification of the rolling stock exploitation, giving the opportunity to rationalize the use and exploitation. The publication presents the author’s graph of the exploitation process taking into account the profiling of the vehicle fleet. The application of the presented approach will contribute to the improvement of the value of certain vehicle reliability and exploitation indicators.

The article includes an analysis involving the requirements for the adaptation of rolling stock for use by people with movement dysfunction. The requirements including construction and dimensions have been summarized and detailed conditions necessary to ensure the assumed level of travel comfort for people with reduced mobility with real examples of solutions used in currently operated railway vehicles. The focus was on the requirements set out in Regulation No 1300/2014 regarding technical design and construction solutions for adapting railways to the transport of disabled people, TSI PRM. Based on the collected material, an analysis of the compliance of the actual state with the theoretical one, included in the standard, was carried out. Elements designed and manufactured in a manner consistent with the recommendations contained in the standard, as well as those that require a re-analysis of rolling stock constructors, repair or necessary changes are indicated. The components analyzed included, among others, seating positions, movement zone - including internal and external doors, toilets or platforms enabling access to the interior of the vehicle The opinion of disabled people using rail transport was also included by conducting a survey and performing analysis and then interpretation of the data obtained. Basing on this analysis, solutions that will increase the comfort of travelling for people with disabilities have been proposed.

The paper presents the research results of the stability and loading of the two-axle mine cars and rail tracks with various design for calculation schemes construction of transport systems of underground rail haulage. The dependences of changes in loading, stability and operation safety of rolling stocks from the parameters of irregularities, curvature radii of the rail track and the movement speed of rolling stocks at various technical solutions of the transport system, have been studied. The research results of the interaction between the two-axle mine cars and rail track with the gauge of 750 mm for underground rail haulage are presented. The parameters have been determined of the rail track irregularities in the horizontal and vertical planes, which cause the highest values of vertical and horizontal loads, acting on the rail track and the two-axle rolling stock. The recommendations are proposed for improving the study of the rail vehicles and regulatory documents development for the construction and operation of the track structure. The results can be applied for the underground rail haulage when creating the new vehicles for mines.

Currently much attention is paid to the development of the Arctic zone of the Russian Federation. First of all, we are talking about the development of mineral deposits. The peculiarity of these territories is a very low population density, less than 1 person per square kilometer. The living conditions for people there are really not the best. At the same time, without proper transport support for these territories, the development of deposits is impossible. In this regard, the possibility of using "deserted" technologies in all spheres of human life comes to the fore. Today the world is actively developing Big Data technologies that allow you to process large amounts of data. And this means that people can rest and entrust routine operations to a computer. Rail transport looks most advantageous as a transport support for the Arctic zone. The main railway transport systems are railway tracks and rolling stock with integrated systems that ensure the safety of the transport process. The functioning of these systems should be co

Background: In a world where every municipality is pursuing the goals of more sustainable mobility, bicycles play a fundamental role in getting rid of private cars and travelling by an eco-friendly mode of transport. Additionally, private and shared bikes can be used as a feeder transit system, solving the problem of the first- and last-mile trips. Thanks to GIS (Geographic Information System) software, it is possible to evaluate the effectiveness of such a sustainable means of transport in future users’ modal choice. Methods: Running an accessibility analysis of cycling and rail transport services, the potential mobility demand attracted by these services and the possible multimodality between bicycle and rail transport systems can be assessed. Moreover, thanks to a modal choice model calibrated for high school students, it could be verified if students will be really motivated to adopt this solution for their home-to-school trips. Results: The GIS-based analysis showed that almost half of the active population in the study area might potentially abandon the use of their private car in favour of a bike and its combination with public transport systems; furthermore, the percentage of the students of one high school of Palermo, the Einstein High School, sharply increases from 1.5% up to 10.1%, thanks also to the combination with the rail transport service. Conclusions: The GIS-based methodology shows that multimodal transport can be an effective way to pursue a more sustainable mobility in cities and efficiently connect suburbs with low-frequent public transport services to the main public transport nodes.
