Railroad switches, also called turnouts or points, are a key element of the rail network infrastructure. They are distributed all over the network and their maintenance is crucial to guarantee safety and undisturbed operation. Within a railway network, the turnouts are responsible for a high amount of the operational costs as monitoring and maintenance is mainly manual. Using a combination of measurement data and physics-based simulations – a typical Digital Twin application – has a high potential to identify failures before they become critical. Defining a general methodology to derive such solutions which make use of all the relevant information created along the lifecycle is the subject of our current research.
