Abstract

A model for investigating resonance conditions in electrified railway track is presented. The short-circuit and open-circuit input impedances as functions of frequency and feeding track length are calculated from frequency-dependent track phase impedances and admittances found from verified finite element modelling. The corresponding characteristic impedances and propagation constants are also calculated. The results of the study are useful to practising engineers in assessing power and data transmission properties of rail track. 1 Introduction Knowledge of the input impedance of electric traction networks is of interest to electrical and communication engineers engaged in the design of
