This paper presents an approach for modeling and veri - cation of components controlling behaviour of safety-critical systems in their physical environment. In particular, we introduce the modeling language FocusST that is centred on specifying time and space aspects. Veri cations can be carried out using the interactive semi-automatic proof assistant Isabelle. The approach is exempli ed by means of a railway system scenario.
