Abstract (EN): The simulation of the dynamic behaviour of railway tracks under high-speed traffic is a complex problem and it has constituted one challenge for many researchers in the last years. Although in recent years complex numerical models in this domain have appeared, the use of analytical models continues to have its importance, mainly in the preliminary stages of design or in the validation of numerical models. In this paper, different analytical models to simulate the track response under high-speed traffic are presented and discussed and a new methodology for determination of input parameters is proposed. Some aspects of the dynamic behaviour of the railway track are analyzed by means of the application of the model to a case study and by the development of a parametric study.
