This paper presents the results of a study aiming at increase the knowledge of degradation phenomenon resulting in geometrical railway track irregularities. The paper show how data collected from ROGER 1000 together with variables affecting the degradation can be used to predict progression of railway track irregularities. The paper also describes a model which has been developed to show the relations between the irregularities and variables affecting it. The model has been developed using multivariable regression modeling.
