“…An example is the Hybrid ERTMS/ETCS Level 3 concept, which tries to bring the flexibility of moving block train separation to a signalling system based on traditional trackside train detection [58]. The application of formal modelling and analysis techniques have proved to be beneficial for improving the specification of the concept and for coping with its complexity [10,31,7,38,41,62,81,57,15].…”

In 2020, the EU launched its sustainable and smart mobility strategy, outlining how it plans to have a 90% reduction in transport emission by 2050. Central to achieving this goal will be the improvement of rail technology, with many new data-driven visionary systems being proposed. AI will be the enabling technology for many of those systems. However, safety and security guarantees will be key for wide-spread acceptance and uptake by Industry and Society. Therefore, suitable verification and validation techniques are needed. In this article, we argue how formal methods research can contribute to the development of modern Railway systems -which may or may not make use of AI techniques -and present several research problems and techniques worth to be further considered.

“…The article Formalising the Hybrid ERTMS Level 3 specification in iUML-B and Event-B, by Dghaym et al [6], describes the use of UML-B for modelling and analysis of the ERTMS case study. UML-B is a graphical version of Event-B that provides class diagrams and state machine diagrams based on UML.…”

This paper introduces the topic of the Special Section on the ERTMS Level 3 Hybrid case study. The European Rail Traffic Management System (ERTMS) is a system of standards for management and interoperation of signalling for railways. The case study focuses on the ERTMS Level 3 Hybrid principles, which accommodates different types of trains, including trains equipped for ERTMS and non-ERTMS trains. The Special Section contains seven contributed articles describing the application of a formal method to the case study and these contributions are outlined. A overview of the assumptions and requirements of the case study are presented at a level of detail sufficient for the reader to follow the contributed articles.

During the early phases of software system development, error detection can be challenging due to the complexity of both the requirements and the operating environments. This paper advocates for the utilization of formal modelling and verification throughout the first phases of systems development to promptly detect and correct errors. The formalism employed throughout is Event‐B, which is backed by the Rodin toolset. To conquer requirements complexity, the frameworks of set theory and first‐order logic are employed, which provide the necessary tools for formalizing and analysing the properties and behaviours associated with Event‐B. Also, we detail the way in which modelling may be used to achieve abstraction, as well as the way in which refinement can be used to manage complexity through layering. Furthermore, we emphasize the significance of model validation and verification in improving the precision of formal models and requirements in IoT communication systems. The model is exemplified using a Content‐Based Publish Subscribe System (CBPS), with a special emphasis on a fire alarm system as a motivating example.
