Research on retrofitting batteries to EMUs for safer, efficient 3rd rail DC network.
RSSB is procuring research services to explore the opportunities that retrofitting modest capacity traction batteries to Electric Multiple Units (EMUs) presents for improving safety and efficiency of the 3rd rail DC network. The research will assess technical feasibility, operational benefits, and safety implications. Bidders should have expertise in railway traction systems, battery technology, and DC electrification. The contract value is not specified, but it is a research project likely under £100k. The buyer is RSSB, the UK rail safety and standards body.
