Abstract
Purpose. The publication presents the importance and influence of railway traffic control system documentation on its safety. Furthermore, it presents certain selected issues of formal and semi-formal descriptions. Methodology. Development of correct and complete descriptions of the informal, semi-formal and formal becomes important in terms of safety requirements. Background documentation and forms of command-control and signaling system description are the base documents of safety proof. It seems necessary to implement the analysis of the design, manufacture process and operation of safety-related equipment into the work of the Polish railways. Firstly it is applied to traffic control devices. Findings. This publication also shows the importance of risk analysis, which is essential when deciding on the implementation of signaling systems to operate, which are required both in the regulations and making rational decisions about the implementation of the systems. Originality. The presented a problem changes the approach to certain data and makes us aware of their validity. Practical value. The presented problems can help understand certain legal requirements.
Highlights
Safety is the basis of any rail transport and signaling system
These changes were initiated in 2004 under the provisions of the Directive on rail safety. This Directive makes it clear that all operators of railway systems, infrastructure managers and railway carriers should bear full liability for the security of the system, each one to their respective extent. This issue is a novelty in the rail industry and causes a lot of confusion of interpretation disputes, in particular due to the fact that it falls within the overlaping areas of technical and management sciences
The units assessing the adequacy of the risk management process in railway transport were forced to undertake activitied under the Commission Regulation (EC) No 352/2009 [10] on the adoption of a common safety method on risk evaluation and assessment, and the Commission Implementing Regulation (EU) No 402/2013 on the common safety method for risk evaluation and repealing Regulation (EC) No 352/2009
Summary
Risk analysis is a key element of safety management systems in rail transport. Within the RTC systems, safety is the key factor which qualifies a particular system for release to service. PN-EN 50126 standard determines the reliability, availability, maintainability and safety (RAMS), as a process based on the system life-cycle. This process defines particular stages of the system and procedures for approval before moving on to the stage (requirement specification, design, implementation, etc.). Standard EN 50129 defines the requirements for the design, testing, commissioning and approval of electronic systems, subsystems and related signaling devices with security in railway applications
