Cover Story: Railway noise barriers are subjected to high aerodynamic loads during train passages. Due to the current increasing number of trains and train speeds, material fatigue becomes important for all construction parts. The objective of this paper is to develop an efficient combination of visual inspection with data-based methods of monitoring and digital twin modelling to perform a reliability-based remaining service life assessment of fatigue-prone elements of noise barriers. These approaches are combined into a progressive four-stage model in which the information content increases with each model stage, and thus successively increases the accuracy of the determined structural conditions and the prediction of the remaining service life, and therefore enables infrastructure operators to ensure the structures’ safety more economically.
