Abstract
The importance of providing digital twins for infrastructure arises from the urgent necessity to enhance the efficiency, resilience, and sustainability of infrastructure systems. A digital twin (DT) refers to a digital replica of physical assets, processes and systems, it brings the opportunity to turn passive infrastructure assets into cyber-physical systems. Despite the increasing trend, the transportation industry lacks reviews on DTs, especially in the area of railway systems. This article shows several opportunities and advantages of DTs, focusing on the use of DTs in the railway sector. It also provides a review of existing DT architectures. The study highlights the importance of acquiring a systems perspective when designing DTs today to facilitate the development of interoperable systems of systems in the future. To this end, we present a conceptual architecture of railway subsystems integrating seamlessly digital models and data into a holistic large-scale railway infrastructure system.
