A large part of the transport of hazardous materials is carried out by rail. Therefore, the security of these transports is becoming increasingly important. Every catastrophe involving dangerous materials has a negative impact on the participants of the incident and the surrounding environment, because its range is generally not local. It follows that in the event of a catastrophe, its effects should be minimized and remediation should be considered in further actions. This whole process of minimization is possible only when we know the mechanism of spreading the effects of a catastrophe involving hazardous materials in the track, subgrade and ground. It should be remembered that in an extreme case, a catastrophe involving hazardous materials may even lead to an ecological disaster. Dynamic systems, especially those with distributed parameters, can be used to describe the mechanism of the disaster's spread. Properties of phenomena accompanying the analyzed catastrophes are well reflected in their linear or non-linear mathematical models analyzed using various operator methods.
