## Summary

The Rail Safety and Standards Board (RSSB), located in London, is actively seeking research services through an open competition procurement method. The project, titled "Investigating and proposing improvements for rolling stock heat insulation provision," is focused on examining and enhancing heat-insulation practices for passenger rolling stock in Great Britain. The tender is currently in the 'tenderUpdate' stage, with a key deadline for the submission of tenders set for 13 January 2026. Interested parties should also note the enquiry deadline, which is 2 January 2026. This procurement falls under the services category, specifically within the research services industry.

This tender represents a significant opportunity for businesses specialising in research, vehicle design, or materials science, particularly those with expertise in insulation technologies and environmental sustainability. Companies with strong capabilities in providing evidence-based recommendations and innovative solutions for energy use and carbon reduction can greatly benefit from this opportunity. Small and medium-sized enterprises (SMEs) are encouraged to participate, as the contract's suitability criteria acknowledge their involvement. The project's focus on cost-effective and sustainable insulation solutions for both new-build and retrofit applications could forge new partnerships and stimulate business growth in related sectors.

## Notice

RSSB is commissioning research to review current heat-insulation practices in GB passenger rolling stock, benchmark them internationally, and identify practical opportunities for improvement across both new-build and retrofit vehicles. The project will assess suitable insulation materials and technologies (including thermal performance, fire safety, durability, and end-of-life considerations), evaluate how vehicle design and operation influence heat loss, and quantify the benefits of potential improvements in terms of energy use, carbon reduction, operating costs, and passenger comfort. The outcome will be clear, evidence-based recommendations to support industry decision-makers in adopting cost-effective, technically robust, and sustainable insulation solutions.
