An introduction to validation challenges

Testing and validating an on-board ‘European Vital Computer’ (EVC) requires a specific test-environment with the ability to simulate all the stimulus, signalling and interfaces with which an EVC can exchange information. The European Union Agency for Railways has listed1 and publicly disseminated the performance requirements and guidelines to be utilised when developing such a facility. This article from Salvatore Vetruccio, Assessor – CCS On-Board Department at Italcertifer outlines the company’s efforts in developing such a system and the process that led to its success.

Our work began with the aim of designing a system of simulation that best reproduces the environment around EVC during the time a train is in operation: the proposed model has got to recreate (indoors) a full series of railway scenarios that the vital computer will face during its operational lifetime2.
