Railways have been evolving with the development of new materials and advances in geotechnical engineering. New track components (concrete sleepers, slab track, fastening systems, resilient elements) are developed as alternatives to more classical ones (wooden sleepers, ballasted track). Many studies have been performed on the dynamic behaviour and performance of these components as well as the railway infrastructure. 

The scope of this mini-symposium is on efficient computational methods for the dynamic analysis of railway tracks and their components, as well as the impact of railway infrastructure on the built environment. 

Papers are welcomed on advanced computational and analytical methods for railway track modelling, such as: finite element or coupled finite element-boundary element models; 3D, 2.5D and periodic models; reduction techniques; linear and non-linear models; deterministic and stochastic models; forward and inverse models.

Problems of interest may include, for example: the dynamic response of ballasted or slab tracks and their foundation; dynamic loading induced by transition zones (non-homogeneous foundation, bridges, tunnels,…), damaged components (sleepers, ballast,…), or geometrical defects; inverse problems as the identification of track defects and wheel-rail contact forces, as increasingly applied in embedded and on-board measurement systems.
