Abstract:

Effective logistics management plays a crucial role in the railway industry for transporting goods and people. There is a need to improve the railway infrastructure to meet today's increasing demand for railway transportation. Digitalising the railways help improve the old dilapidated infrastructure which could cause train delays in railway logistics. Interlocking testing is a priority, requiring stringent procedures guided by rail safety regulations. Historically interlocking testing required significant protocols and effort resulting in expensive resource allocation in the form of personnel, equipment, and time. This study examines modernised technology that presents the new configuration setup and improves processes that can potentially replace traditional methods. The findings of this study prove that the use of this new technology in railways can significantly reduce the amount of time spent on this process, increase the reliability, and save on human resources.

Abstract:

The operational stock of signals and interlockings is necessary to ensure the uninterrupted operation of the electric interlocking systems in the event of their component failure. The existing standards for the composition and number of signals and interlockings available in the operational stock of railway stations are not mathematically based. It is considered the task of justifying the number of signals and interlockings in the operational stock of railway stations, and the factors affecting its quantity are indicated. It is proposed the mathematical model for rationing the amount of equipment necessary to ensure the uninterrupted operation of station signals and interlocking systems with a specified probability. The process of using and replenishment of reserve equipment is described using the the single-channel Markov queuing system model with a limited queue. The proposed probabilistic methodology approbation for the rationing of the amount of reserve equipment was carried out at the stations of the two Belarusian Railway divisions totaling to 58 stations equipped with relay and computer-based electric interlocking. It is shown the efficiency of the calculated amount of equipment in comparison with the existing values.

Abstract:

The safety of railway networks is a very important issue. Roughly speaking, it can be split into safety along lines and safety of railway facilities such as stations, junctions, yards, etc. In modern networks the safety along lines is controlled by automatic block systems that do not give clearance to trains to enter a section (block) until the latter is detected to be unoccupied. Meanwhile, the safety within railway facilities is supervised by railway interlocking systems. Decision making in a railway interlocking is a very important issue which is considered to be very labour-intensive. Decision-making in both automatic block systems and railway interlocking systems, unlike road traffic light systems, is not based on time (they are not scheduling problems) but in space. Basically, two different trains should never be allowed to access the same section (whatever time has passed). There are many different approaches to automate decision-making in railway interlocking systems. The classic approaches are offline: only certain routes are allowed and their compatibility is decided in advance. Meanwhile, modern approaches make decisions in real time and are independent from the topology of the railway network, but can be applied only to small or medium size railway networks. Nevertheless, these last approaches have the following drawbacks: the performances are very dependent on the number of trains in the railway network; and are unsuitable to large networks since they take long time to be run. On the other hand, algebraic approaches based on computer algebra concepts have been used in artificial intelligence for implementing expert systems. In this paper we present a completely new algebraic model, based on these concepts of computer algebra that overcomes these drawbacks: the performance of our approach is independent of the number of trains in the railway network and also is suitable for large railway networks.

Abstract:

High levels of reliability and high security are the basic characteristics and requirements of railway signal systems. So, reliability, availability and maintainability (RAM) are necessarily analyzed before the computer interlocking system will be adopted. The All-electronic Computer Interlocking System, which is a new kind of interlocking system, still needs to analyze its RAM before being put to use. In this paper, the reliability methods and Markov model are adopted to analyze the RAM indexes of the All-electronic Computer Interlocking System when its execution layer equipped with the single configuration or the dual-redundant configuration, the paper also compares the indexes with that of the traditional computer-based interlocking system. Finally, the paper will briefly include suggestions on how the All-electronic Computer Interlocking System’s RAM indexes may be increased and also, how the system may be used practically.

Abstract:

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.

Abstract:

The paper discusses the issues of incident management at technical operation of microprocessor systems of railway automation and telemechanics on the railway network of the JSC Russian Railways. The widely used microprocessor interlocking centralization of switches and signals (MPI) EBILock 950, the development of a joint Russian-Swedish company Bombardier Transportation (Signal), is considered as an object of the research. The analysis of algorithms and patterns of interaction between the operating staff of operating enterprises and specialists of service centres revealed a number of shortcomings in the system of the MPI maintenance and repair organization. As a result, the authors have proposed an alternative scheme for organizing the technical operation of microprocessor systems based on the incident management system implemented as a web application. This application makes it possible to monitor the quality and timing of service operations, accumulate information on methods for eliminating complex non-standard failures and automate the processing of requests by service centres.

Abstract:

With the rapidly growing of passenger flow in big city, Communications Based Train Control (CBTC) system is believed to be the chief choice for urban railway transportation system. Interlocking system is a key safety critical application for CBTC, as it provides trains safety routes both in normal condition and under degraded mode. To deal with the logic complexity and high demand for safety, this paper addresses a novel scheme for modeling and realization of CBTC interlocking system. Using SCADE toolset, core function model prototypes are elaborated and software codes are generated automatically. The practical application indicates that this method provides an accurate and complete description for the whole system, and offers a path to gain high quality system implementation.

Abstract:

The article presents a family of innovative products rmRailProtector 4.0, which are a comprehensive solution for the ERTMS / ETCS functionality on L1 level. The presented system was developed in Poland using Polish technical thought and the potential and many years of experience of Rail-Mil in the design, production, implementation and operation of train traffic control systems. The rmRailProtector 4.0 system thanks to cooperation with the experts of KOMBUD S.A. Automation Group as a comprehensive solution, it is adapted to work with the MOR-3 – multi-computer interlocking system used to control of railway traffic. The first planned implementations of rmRailProtector 4.0 systems assume a configuration consisting of MOR-3 interlocking system and rmRailProtector 4.0 system with ERTMS / ETCS level L1 functionality. rmRailProtector 4.0 covers devices, including: Eurobalises in the fixed and programmable version, an innovative fiber interface in the LEU-Eurobalise relation, standard and centralized LEU encoders as well as programming and diagnostic tools, according to the CCS TSI requirements (Technical Specifications for Interoperability, Control-Command and Signaling). The article synthetically summarizes the basic functional, formal and legal aspects of the proposed solutions, with reference to the requirements for the interoperability of the rail system. An innovative approach to the design of the ERTMS / ETCS L1 system was presented in detail, including the wide application of fiber optics in the connection of Eurobalise with LEU and the innovative supply of Eurobalise using optical interface. The article intentionally omits the presentation of centralized LEU, including innovative LEU with an optical interface, which will be presented in subsequent publications. The approach presented above is a new quality in the area of extensive network design at large railway stations. The innovation of the presented solutions found expression in the complex to Patent Office of the Republic of Poland with the patent application identification number: P.430674.

Abstract:

The communication system that is presently applied in the European Train Control System can only support data exchange between vehicles and ground, but the direct vehicle-to-vehicle communication is not available. The details of interlocking information and other vehicles’ movements are invisible to drivers who are the last defense to prevent unsafe scenarios. As connected vehicles have been envisioned to enhance transportation efficiency and improve safety, the direct vehicle-to-vehicle communication network is involved in this paper to increase the safety of railway transport. In this paper, a new train movement authority (MA+) is proposed. Apart from a wireless communication unit, this system does not require any other infrastructure. With the assistance of vehicle-centric communication technology, MA+ can detect the condition of switches and trains within a certain scope. In this paper, the system structure of MA+ is proposed. Additionally, different implementation scenarios are also discussed. The detection range is estimated and validated based on mathematical calculation and experimental equations. An application demo of MA+ is presented on the Driver Machine Interface of the onboard equipment. The results indicate that MA+ can be a flexible and scalable system for furthering the improvement of railway safety.

Abstract:

The main trunk lines of the Rhodesian railway system were built under the aegis of Cecil Rhodes' British South Africa Company (BSA Co.) between 1890 and 1911. This article begins with an analysis of the motivations behind railway construction during this period. It argues that interpretations which set up a dichotomy between ‘Rhodes-as-imperialist’ and ‘Rhodes-as-capitalist’ are misconceived. Nevertheless, it shows how the motivations behind railway development took on a more narrowly economic and financial character after the fiasco of the Jameson Raid in 1896 put paid to Rhodes' sub-imperial ambitions.There follows an analysis of the economic and financial foundations of the BSA Co.'s regional railway monopoly. The article charts how railway construction was sustained through the manipulation of the interlocking interests of the BSA Co. and the Witwatersrand; through the creation of a ‘group structure’ of railway companies; and through the triangular relationship which developed between the BSA Co., Paulings, the monopoly contractor, and d'Erlangers, the chief broker and underwriter of railway loan (debenture) capital.Finally, two fundamental allegations made by critics of the railway policy of the BSA Co. are assessed: firstly, that debenture finance was a means of distributing disguised dividends to itself and its friends; secondly, that these disguised dividends were paid for by the settlers through exorbitant railway rates. The nature of debt within the railway monopoly, the functions of debenture finance and the imperatives which shaped rating policy are discussed. The allegations are revealed to be ill-founded. It is argued that the tensions between the settlers and the BSA Co., their interdependence notwithstanding, were rooted in conflicting perceptions of what the priorities and parameters of economic development should be.

Abstract:

Software tools using computer simulations are frequently used in the research and optimization of railway transport systems. Such simulations serve to examine different railway traffic scenarios (which typically reflect different timetables and railway infrastructure configurations). During the simulation experiments, it is necessary, among other things, to solve tasks related to the determination of track routes along which individual trains or parts of train sets are moved. Many simulation tools require the basic and alternative permissible track routes to be manually specified before starting the simulations, which is a relatively tedious and time-consuming process. Classical graph algorithms cannot be applied to solve the problem of automatic calculation of the routes because they are unable to take into account the length of the object being moved or recognise changes in the direction of its movement. This article presents original innovative algorithms focused on automated dynamic search of track routes (applying an appropriate optimization criterion), which is performed during simulation experiments within simulators working at the mesoscopic level of detail. The algorithms are based on a mathematical model (represented by a specifically designed weighted digraph) that appropriately reflects the actual track infrastructure. The dynamic calculation of each specific track route for a train or a group of railway vehicles considers both the total train set length and the current railway infrastructure occupancy, including blocked parts of the infrastructure due to intervention of the interlocking system. In addition, the places where the train set movement direction is changed can be identified on each route found. Applications of the algorithms and of the mathematical model of the track layout are demonstrated on a model track infrastructure.

Abstract:

With the ever-increasing industrial demand for bigger, faster and more efficient systems, a growing number of cores is integrated on a single chip. Additionally, their performance is further maximized by simultaneously executing as many processes as possible. Even in safety-critical domains like railway and avionics, multicore processors are introduced, but under strict certification regulations. As the number of cores is continuously expanding, the importance of cost-effectiveness grows. One way to increase the cost-efficiency of such a System on Chip (SoC) is to enhance the way the SoC handles its power consumption. By increasing the power efficiency, the reliability of the SoC is raised because the lifetime of the battery lengthens. Secondly, by having less energy consumed, the emitted heat is reduced in the SoC, which translates into fewer cooling devices. Though energy efficiency has been thoroughly researched, there is no application of those power-saving methods in safety-critical domains yet. The EU project SAFEPOWER (Safe and secure mixed-criticality systems with low power requirements) targets this research gap and aims to introduce certifiable methods to improve the power efficiency of mixed-criticality systems. This article provides an overview of the SAFEPOWER reference architecture for low-power mixed-criticality systems, which is the most important outcome of the project. Furthermore, the application of this reference architecture in novel railway interlocking and flight controller avionic systems was demonstrated, showing the capability to achieve power savings up to 37%, while still guaranteeing time-triggered task execution and time-triggered NoC-based communication.

Abstract:

The original RailML specification comes from 2002 and was defined using XML. Files in the RailML standard can be used for storing and exchanging data between numerous interfaces of railway ICT systems. Current version 2.4 includes rolling stock and railway traffic management, timetables, passenger information as well as booking and selling tickets. In the upcoming version of the RailML 3.1 standard, the subcheme is included, which is intended for the description of railway interlocking systems. In addition, compliance with the object-oriented, abstract data model for the railway infrastructure, defined in the UIC IRS 30100 standard (RailTopo-Model, RTM), will be ensured. In the paper, the authors discuss the current state of RailML and its perspective. Particular attention is paid to the use of RailML for the description of railway interlocking systems. The authors also present their proprietary software which allow to edit, visualize and verify RailML files.

Abstract:

Multiple projects within the rail industry across different regions have been initiated to address the issue of over-population. These expansion plans and upgrade of technologies increases the number of intersections, junctions, and level crossings. A level crossing is where a railway line is crossed by a road or right of way on the level without the use of a tunnel or bridge. Level crossings still pose a significant risk to the public, which often leads to serious accidents between rail, road, and footpath users and the risk is dependent on their unpredictable behavior. For Great Britain, there were three fatalities and 385 near misses at level crossings in 2015–2016. Furthermore, in its annual safety report, the Rail Safety and Standards Board (RSSB) highlighted the risk of incidents at level crossings during 2016/17 with a further six fatalities at level crossings including four pedestrians and two road vehicles. The relevant authorities have suggested an upgrade of the existing sensing system and the integration of new novel technology at level crossings. The present work addresses this key issue and discusses the current sensing systems along with the relevant algorithms used for post-processing the information. The given information is adequate for a manual operator to make a decision or start an automated operational cycle. Traditional sensors have certain limitations and are often installed as a “single sensor”. The single sensor does not provide sufficient information; hence another sensor is required. The algorithms integrated with these sensing systems rely on the traditional approach, where background pixels are compared with new pixels. Such an approach is not effective in a dynamic and complex environment. The proposed model integrates deep learning technology with the current Vision system (e.g., CCTV to detect and localize an object at a level crossing). The proposed sensing system should be able to detect and localize particular objects (e.g., pedestrians, bicycles, and vehicles at level crossing areas.) The radar system is also discussed for a “two out of two” logic interlocking system in case of fail-mechanism. Different techniques to train a deep learning model are discussed along with their respective results. The model achieved an accuracy of about 88% from the MobileNet model for classification and a loss metric of 0.092 for object detection. Some related future work is also discussed.

Abstract:

Abstract The quality of the transport process in railway transport depends on the compliance of the timetable. Delays in rail transport are due to various reasons. One of the common factors is also failures in the stations or track interlocking systems. In the article is published the results of the performed simulation of failures of interlocking systems in the conditions of the transport laboratory at the Department of Railway Transport. The research was part of a student project solved at the University of Zilina.

Abstract:

On account of the growing number of railway upgrading projects implemented in Poland, numerous problems are emerging when prepared and performed. While preparing detailed plans and specifications for railway traffic control devices intended to secure traffic at a railway station, one must deal with numerous alterations related to the work's phasing directly linked with the said equipment. Consequently, the variety of elements subject to change includes the schematic plan and the relevant interlocking tables for railway traffic control systems. This article aims to discuss the authors’ original method for automation of the generation of interlocking tables for station traffic control equipment. The solution to the problem in question is assumed to be a model consisting of two components. One of them is the design part identifying individual objects comprising the railway station being designed. Subsequently, by the application of adequate algorithms, data are implemented in the other model component. Further calculations are performed to generate a list of all possible movements from main signals and shunting signals at the station referred to as railway routes. The method has been verified using the authors’ original computer program. Its first part corresponds to the design process. The station’s track layout is built using the program’s dedicated toolbar combined with an additional database of layers created in computer-aided design software. Next, such a track layout, saved into a dxf file, is imported to a dedicated application where train and shunting routes are generated. The method is verified by checking the routes thus generated against those in the existing interlocking tables by applying an adequate significance indicator. Assuming that the design process's basic assumptions are satisfied, the method in question makes it possible to accelerate the generation of interlocking tables in a secure manner.
