This article deals with the railway traffic control and railway traffic equipment in terms of implementation of TSI. The main goal is to research the optimal priority of international freight expresses, especially in the overlapping sections, which represent critical line sections of European freight corridors. This article shows this problem in the context in the overlapping section of RFC 7 and RFC 9 Kolín – Ceská Trebová. There are mentioned possibilities of using of ETCS and implementation of automatic train paths.

Expert Classification

Many high-risk industries identify non-technical skills as safety-critical abilities of the operational staff that have a protective function against human fallibility. Based on an established non-technical skills classification system, methods for expert knowledge elicitation were used to describe non-technical skills in the specific context of train traffic control in the Netherlands. The findings offer insights regarding the skill importance for good operational outcomes, skill difficulty, categorization, and attitudes based on subject matter experts’ opinions. Substantial overlap between the employed non-technical skills framework and the observed expert classification was found, which might indicate that the experts utilize a mental model of nontechnical skills similar to the one used. Furthermore, considerations concerning the organizational culture and the attitudes towards change provide a promising outlook when introducing novel solutions to non-technical skill training and assessment.

The Impact

The paper presents the issues of railway traffic control devices testing and focuses on European Train Control System (ETCS) devices widely implemented in railways. The functions of the ETCS system, principles of operation are described. The basic telegrams transmitted in the track-to-train relation are listed. The process of designing and verifying the implemented data and what parameters are checked at the stage of field tests using the locomotive is briefly described. The functional model of the SRK devices, including ETCS elements, was presented, and the close relationship between the base layer of the railway traffic control devices and the ETCS was shown. Equipment testing reduces the availability of the rail network, engages staff, and generates costs. A test generation method is presented to minimize the impact. Two indicators are proposed for reducing the set of checks, the cost of checking and the information effectiveness. The cost of checking due to the problematic estimate is generalized, divided into three groups taking into account the difficulty and resource consumption of bringing the devices to the initial state and their operation according to the test. Therefore, the obtained set of checks is suboptimal and ensures complete coverage of the functions with tests, which is essential when testing devices. The tests are carried out using available setting commands and the implementation of tasks - entry and exit routes at the station. The proposed method is universal and can be applied to any railway traffic control device, regardless of the manufacturing technology. It is a non-invasive method in the structure of the tested devices and does not require additional hardware resources.

Railway Traffic Control Systems (RTCS) provide a safe, reliable and efficient movement of rolling stock on railway networks. RTCSs are classified as critical process systems. The power supply system is required to provide a high level of power reliability so that a station equipment of an RTCS safely executes the rail traffic process. The article describes typical solutions of power supply of station equipment of RTCSs. Analysis of these solutions led to the development of assumptions and structures for the integrated power supply system of station equipment. Useful tools for the formal modeling of such systems can be Petri Nets. These nets are a graphical and formal tool for modeling, formal analysis, and design of discrete event systems. The basic element of the integrated power system which is described in the article is the Automatic Reserve Switching system (ARS system). The ARS controller Marked Petri Net (ARS controller MPN) that has been developed by the authors is presented here. The net was subject to reduction resulting in an ARS controller hierarchical simplified MPN. The article also presents the practical application of the ARS controller built using the hardware platform and graphical programming environment LabView National Instruments (NI).

The Impact

The article presents the concept of integration system of design automation and system of project management. A model was developed cooperation between the two systems on several levels, based on continuous monitoring of the design process and comparing the assumed values of the selected parameters from the actual values. The selection of variables transmitted based on the assumption of cooperation project management system with the system of design automation for railway traffic control devices, designed to support of designers. Due to the nature of projects for railway traffic control devices drew attention to the quality control of the project in the context of the safety and reliability of railway traffic control system, the impact of deviations from the schedule to the railway timetable, version compatibility, and changes in the chamfering work on objects with continuous rail traffic. The structure of the model is presented in graphical form.
