Modelling electromagnetic fields propagated from an AC electrified railway using TLM

This paper provides an application of the transmission-line modelling (TLM) method to the calculation of the electromagnetic field from an ac-electrified railway. The complexity of such environment requires proper management and understanding of the electromagnetic interference (EMI) that may jeopardize the safety and operational integrity of the railway system, leading to the application of modelling methods to support measurements. The presented model, although simplified, can assist the designer of wayside installations to evaluate the compatibility of the whole system with applicable norms, standards and regulations.
