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.

Benchmarked against retained Find a Tender procedures with CPV division 73. The category anchor is Research services (73110000); this is a deliberately broad market comparator. The comparison is shown at several levels rather than pretending one company or region is always the best benchmark.
| Comparison set | Procedures | Reported bids per procedure | Named award suppliers | Price evidence |
|---|---|---|---|---|
| Market: CPV division 73 | 1,647 | 3 median · 43.6 average (483 of 1,647 with a bid count) | 2.8 average (546 of 1,647 with named award suppliers) | Not published |
| Same buyer | 42 | Not published | Not published | Not published |
| Similar published value (0.5×–2×) | 250 | 9 median · 9 average (1 of 250 with a bid count) | 1 average (1 of 250 with named award suppliers) | Not published |
“Reported bids” is an official aggregate, sometimes reported per lot; it is the closest available competition measure. “Named award suppliers” are winners, not all applicants.
Not enough comparable procedures currently publish both a GBP tender value and a usable lowest-valid-bid value to calculate a responsible price-reduction benchmark. Tenderline deliberately does not infer a saving from named award suppliers or from missing award values.
No planning milestones published.
No linked framework, prior procurement or reprocurement published.
Diagnostic view. “Not published” means this current release does not provide a value.
