A single degree of freedom model is proposed to simulate the response of a three-dimensional track structure subjected to a vertical oscillating axle load. It is shown that a dynamic model could be developed from the classical static Winkler-model. The dynamic model was successfully verified against a linear laboratory model. The course of progressive track settlement, resulting in the deterioration of the vertical track geometry owing to uneven settlement under repeated vertically oscillating axle loads is traced with the help of the model.
