The railway signaling and safety system is the basic system for managing rail traffic. Continuous changes in technology and traffic safety requirements have resulted in numerous improvements. Today, the main pillars of the development of new advanced systems, including railway, are the Internet of Things, cloud computing, artificial intelligence, data analytics, Industry 4.0 and cyber-physical systems. Railways, as a complex management system, are certainly affected by the impact of these changes. However, due to their importance, the way they are managed and the size of the railway, they show a high degree of slowness in change. This paper seeks to address, at least in part, the challenges posed by the announced revolution in the management of industrial environments, and changes to the ERTMS standard. Emphasis is placed on the transformation of existing signaling systems as rigid industrial communication and control networks into more adaptable open communication systems in terms of data exchange and collection, and the expansion of infrastructure and train monitoring to improve traffic management and equipment maintenance processes. The paper deals with the supervision of a single-track railway and analyzes the problems that arise on it. The main objective of the analysis of the existing systems has resulted in the development of a cyber-physical model of the single-track interlocking system along with the necessary software implementations of the communication interfaces. On the basis of the established model, a comparative analysis of the advantages of this method of traffic management was carried out, as well as a feasibility analysis of the investment which justifies the introduction of a new stratified approach to equipping the railway infrastructure with the aim of creating a unified cyber-physical network. The paper also presents additional analyzes of the benefits of the proposed cyber-physical model, which are manifested in increasing security, reliability and more efficient maintenance
