    Brief

    This research opportunity seeks to explore the technical and operational benefits of retrofitting electric multiple units (EMUs) with modest-capacity traction batteries to enhance the safety and efficiency of third-rail direct current (DC) rail networks. The project aims to investigate how battery systems can improve network performance, reduce operational risks, and optimize energy consumption on existing 3rd rail DC infrastructure. Interested suppliers should review the full tender details on the eSourcing portal and submit responses through the provided link.
