Regardless of the mode of transportation, directional changes generate greater forces on the infrastructure as a result of the lateral load transfer and of the respective steering forces in the vehicles. In the case of Railway transportation, a concentrated damage occurs in the rail at the initiation of the turning maneuver, whose magnitude depends on the bogie´s yaw stiffness and on the level of friction at its centre plate. To mitigate such rail-damaging effects, some new designs have been proposed and used for the bogies´ wheelset. However, no new designs for the centre plate have been used. In this paper, a review of the causality for the forces arising during Railway Vehicle's turn negotiations, is presented, including the description of a modeling framework to analyze the influential Parameters for determining the magnitude of such forces.
