Measurement methods and emission limits for radio frequency noise emitted from railway systems have already been established by the International Electro-technical Committee (IEC). Given the high cost and time consuming nature of the tests required to evaluate the effects of countermeasures aimed at containing the strength of emitted radio frequency noise within the allowable limits defined by the IEC standards, or, to grasp the characteristics of the radiated emissions, has worked on a study to establish a method to calculate the strength of radiated emissions from the railway system through numerical analysis. This paper outlines an improved railway antenna model and simulation support software which employs a numerical electromagnetic analysis software based on the Richmond Method of Moments.
