Abstract
Qualitative assessment of the railway traffic control system is necessary to ensure railway traffic safety. According to CENELEC standards all railway applications are obliged to conduct RAMS (reliability, availability, maintainability and safety) analysis. This process should include the actions associated with design, production, installation, verification, as well as validation and the acceptance of the system. In this paper a safety analysis for the microprocessor-based semi-automatic block signalling was described. Provided analysis allows stating, if the risk is acceptable (and so further analysis is not necessary). If not, then additional protection measures should be implemented in order to keep the hazard and associated risk at an acceptable level. Methodology accepted in this analysis can be used for the evaluation of safety factors for other electronic railway traffic control systems.
