Abstract: Nowadays, the train movement in the spatial system with fixed track sections is the most often used way of organizing of the train movements in track section. Hazard identification is a part of the risk analysis [4]. Risk analysis is one of the early phases of the life cycle of an interlocking system (IS). It is recommended to create a process model, which allows identifying the hazards, associated

In order to define safety requirements for an interlocking system, the hazards associated with the controlled traffic process, their causes, the intensity of their occurrence, their consequences and also the tolerable risk must be known. The analysis of the causes of hazards related to the train movement in a track section and the principle of the division of tolerable hazard rate for each part of the interlocking system (that ensures the safety of the control of train movements in track section) are the main topics of this paper. Analysis of the causes of occurrence of these hazards and the principle of the division of tolerable hazard rate (THR) for different parts of the interlocking system (that ensures the safety of the train movements control in track section) are the further topics of this paper.
