Abstract
The paper deals with problems of using the Unifield Modeling Lanfuage (UML) in developmentt of new railway interlocking and signalling systems. A simplifield example of the control circuit of a point machine is used to demonstrate an object-oriented approach to specifying the functional safety requirements. An informal specification given by the relevant technical standart is used as a starting point and results in semi-formal specification based on UML model. Advantages of the presented approach are discussed and new trends of increasing formality of UML models are indicated within conclusions.
