Turnouts are a part of modern railway tracks to divert railway traffic from one route to another route. Their complex geometry and structure impose significant dynamic track loads. Particularly, common crossings laid on ballasted tracks are well-known among the infrastructure managers for their drawbacks. Numerous studies have been devoted to analyze a railway turnout with a common crossing. Nevertheless, almost all of them considers that turnouts are working in a dry environment. In reality, railway tracks are exposed to extreme conditions such as flooding, which could damage the power supply, signaling systems, rolling stocks and the infrastructure. The so-called phenomenon ‘washed out’ or ‘washed away’ ballast affects directly the dynamic behavior of rolling stock and can cause derailments with fatalities. In 2018, for instance, 25 people were killed in an accident in Turkey as a result of ‘washed away ballast.’ Few studies analyze unprecedented events in railway tracks in terms of vehicle-track interaction. However, no studies on turnouts was encountered in the literature. Hence, it is a significant contribution to analyze a railway turnout in case flooding occurs. In this study, the beam oriented finite element model, validated previously, is manipulated to analyze the dynamic behavior of a turnout under dry and wet conditions as well as washed away ballast scenarios. The outcomes of the study show that considering the effects of flooding on dynamic forces during operation and design phases could be a key to prevent undesired events.
