The article discusses the medological safety issues in railway undertakings, the importance of safety management systems, their structure and their basic elements. In this connection the principles of the management of railway transport and railway enterprises are described. Safety management systems should have: enterprise safety policy, internal company rules and procedures, safety promotion methods, staff training and methods for hazard identification. Seven types of safety analyzes are described: conceptual, initial, detailed, systematic, functional, analysis during exploitation (at work), and according to the safety ments. The methods of safety analysis and assessment can be divided into the following groups: according to the objectives that are pursued, according to the type of analysis and to the chosen logical approaches. The article explores some of the most appropriate methods for safety research: Fault Tree Analysis, Event Tree Analysis, Pareto Analysis, Hazard and Operability Study (HAZOP), X-Tree Analysis and analysis of consequences and factors, called Event and Causal Factors Analysis. Their main goals and their strengths and weaknesses, as well as guidelines for their use are presented. The importance and the role of safety in the improvement of the work of the railway undertaking is defined.
