Reduce of criticality of critical infrastructure facilities in the railway domain

The paper deals with safety improvement of facilities of critical infrastructure in the railway domain based on integral safety management. It means that it solves not only secure facility but also safe facility that is the facility which at itself critical conditions do not endanger either itself or its vicinity, i.e. humans and other public assets. In the modern practice of safety management and safety engineering there are introduced new procedures like All-Hazards-Approach, Defense-In-Depth and for construction of critical facility safety there is used the five-layer model of safety management. The article comprises current state of appropriate railway system with ideal case based on mentioned concept and gives proposal of measures for improving the safety of followed critical facilities.
