The COVID-19 pandemic continues to have a significant impact on railway business. Although it is still difficult to have a clear vision about a Post-Covid Society will be like for the moment railway services must be more reliable in order to avoid concentrations of passengers due to delays or cancellation of trains. In the longer term, railways must focus on lowering carbon emissions and improving maintenance. To this end, RTRI has been engaged in research to improve the reliability of power supply equipment, to save energy during train operation and to improve maintainability of power supply systems. This paper describes some of the outcomes achieved at RTRI through this recent research.
