The brief

This project is being commissioned by the Railway Safety Directorate (RSD), which is the health and safety enforcing authority for the railway industry.

RSD carries out inspection, investigation and enforcement activity as part of its role in enforcing relevant health and safety legislation.

PRIMA (Proportionate Risk Response to Implementing Mitigating Speeds to Assets) is described by Network Rail as a decision-support tool, aimed at assisting control room staff in identifying appropriate speed restrictions that should be imposed in adverse or extreme weather.

It has its origins in RSSB's Research Project T1269 'Development of a system risk model for extreme rainfall events', published in October 2022.

The model has since been further developed by RSSB, to Network Rail specifications.
