Multiscale Modelling in Railway Engineering

The article presents the design and operation of selected types of physical simulation models of the railway track subgrade and transport earthen structures. These models include: - model section of railway track for testing vertical displacements, - test bench physical simulation models of reinforced railway track subgrade, - multiscale physical simulation model of the retaining wall made of reinforced ground stabilizing the transport embankment, The paper discusses the research of the displacement state of the models constructed. The results of research can be the foundation for designing subgrade reinforcements in modernised railway tracks.
