This study investigates the stress-strain state of the KZF-07 rail fastenings under high-speed train movement using the finite element method (FEM). The modeling showed that the stresses in the key components of the fastenings (sleeper, baseplate, clamp, screws, and dowels) do not exceed the allowable values, confirming their reliability. Increasing the stiffness of the rail pads reduces longitudinal stresses, improving the service life of the rails, while the metal components have nearly unlimited service life. It is recommended to optimize the design of the rail pads and investigate the material stability against aging. The obtained results contribute to improving the safety and durability of the railway track under high-speed conditions.DOI
