The paper presents the findings of a study exploring the influence of unloaded rails in connecting tracks on the distribution of deflection of reinforced concrete switch ties when a train moves along the direct track. The finite element method (FEM) was used to develop a spatial analytic model of connecting tracks at a turnover, including both loaded and unloaded rails and switch ties on a continuous elastic cushion. The model was verified by comparing the FEM calculations against the conventional solution for a beam on an elastic cusion using the initial parameter method (Krylov functions). The comparison of results has shown good convergence. The study has identified quantitative relationships between changes in system stiffness and distribution of deflections along the switch tie length based on its length and loading patterns. It has been shown that unloaded rails reduce the maximum deflection by 5–15%, displace the deflection point towards the centre of the switch tie, and contribute to more uniform distribution of deflection. When unloaded rails are excluded from the calculation, the load transfer efficiency factor for switch tie-to-ballast load transfer is overestimated. The “reverse” bending of the switch tie ends typical of the design model of a beam on a continuous elastic cushion remains virtually unchanged when unloaded rails are introduced. This value is mainly determined by the length of a switch tie and stiffness of the cushion, which supports and elaborates on the conventional approaches offered by V.F. Yakovlev and I.I. Semenov.
