Tender: Research and Guidance on Emergency Temporary Repairs for Passenger Rolling Stock Windows

About

The project is seeking a supplier to research and produce clear, evidence-based guidance on temporary emergency repair methods for passenger rolling stock bodyside and door windows. The work must identify which temporary repair methods, including viable alternatives to film, reliably work on current window types and what factors determine their performance; define the loading conditions temporary repairs must withstand, the likelihood those conditions are met by different methods, and any operational restrictions (such as speed and time in service) while a repair is in place; provide practical, well-organised guidance for maintenance teams and the engineers who support them so repairs are selected and applied correctly and consistently across the full range of window mounting and glazing systems currently in use; advise teams working on future rolling stock procurement and design about how different window designs affect the feasibility and reliability of temporary repairs; and clarify remaining evidence gaps with high-level recommendations, including targeted testing.
