Many factors are affecting the broader adoption of electrified railway systems. One such factor is the concern for global climate change, of which the exhaustive fumes of internal combustion engines is a critical contributing factor. Thus, the pressure is growing in the railway applications that the usage of internal combustion engines should be eliminated eventually. Meanwhile, a substantial portion of the applications is already in use, mostly underground railways such as urban metros. Furthermore, the speed of urbanization spurs the faster spread of the electrified mass transportation systems. Consequently, the need for testing and evaluation in an electric traction system has been growing. In this paper, one such approach, real time simulation and its application towards testing and evaluation of electric traction systems, is presented. Its application in a congested marshaling yard circumstance is given to probe the usefulness of the proposed concept.
