The project ADVENTURE (ADVancEd iNtegraTed evalUation of Railway systEms) aims to provide novel solutions for the evaluation of RAMS requirements as well as to present trade-offs between dependability attributes and energy consumption in complex railway systems, leveraging both qualitative and quantitative evaluation methods. To this end, case studies concerning distributed interlocking systems, standard interfaces, and railroad switch heaters are considered, comprising different challenging scenarios, notably representative of the complexity of railway systems. In this paper, we illustrate the objectives of the project and the activities planned to address them, devising future steps to integrate the envisaged contributions within a unified framework.
