Abstract

SafeCap is a modern toolkit for modelling, simulation and formal verification of railway networks. This paperdiscusses the use of SafeCap for formal analysis and fully automated scalable safety verification of solid state interlocking(SSI) programs – a technology at the heart of many railway signalling solutions around the world. The main driving forcebehind SafeCap development was to make it easy for signalling engineers to use the technology and thus to ensure its smooth industrial deployment. The unique qualities and the novelty of SafeCap are in making the use of formal notations and proofs fully transparent for the engineers. In this paper we explain the formal foundations of the proposed method, its tool support, and their successful application by railway companies in developing industrial signalling projects.
