“…Over the last two decades, non-ballasted track has been the main choice in railway construction [11]. Ballasted track typically have lower initial capital costs than nonballasted tracks typically and have higher operational costs in comparison to non-ballasted track [12]. Ballasted tracks require higher operating costs than non-ballasted tracks due to more frequent maintenance to maintain the track geometry in line with the original design [13].…”

Damage due to wheel wear on railway trains has a significant impact on railway safety and comfort. This review examines various aspects related to wheel wear damage on trains. The primary focus of this review encompasses three critical areas: railway track, wheel-rail interaction, and the trains themselves. The first section discusses the structure and modeling of railway tracks, while the second section explores various types of interactions between wheels and rails as well as related mathematical models. The third section reviews the types of railway vehicles, their mathematical models, and their stability on straight and curved tracks. Furthermore, this review also examines the influence of wheel wear on the dynamic response of the system. It is hoped that this review will provide valuable insights for practitioners and researchers in improving and enhancing the reliability and safety of railway systems.

“…For instance, in ballasted tracks, the pattern is given by the repeated sleeper arrangement [16,17]; whereas in slab tracks, this is generated by the discrete rail-seats or repeating slab units [18,19,20,21]. Among the various periodic approaches, the 2.5D FEM has been extensively used for train-track-ground simulations in recent years [22,23,24,25,26,27]. Typically, this method is coupled with BE or PML (perfectly matching layers [28]) to account for the wave propagation response.…”

Periodicity can be defined as the repetitive character of a structure's features. In railway track systems, periodicity can be found in the geometrical and material properties in the train passage direction. For example, the repeating pattern of sleepers, rail seats or slab track units. To take advantage of this, this paper employs the direct periodic method, a novel numerical method which exploits the invariant nature of the railway track structure. Instead of simulating the total track domain, the direct periodic method studies a discrete portion of the track, often known as the reference cell, which captures its repetitive pattern and provides the total track response. First, the cell response is obtained by enforcing compatibility conditions within its system of equations of motion in the wavenumber-frequency domain. Then, the total space response is retrieved by replicating the cell's solution via a combination of periodic conditions and Fourier transformations. It is combined with perfectly matched layers to simulate infinite depth soil boundary conditions. Thus, this paper employs the direct periodic method in combination with perfectly matching layers to analyze track-ground dynamic interaction.
