System Safety Engineering (CSM RA Compliance)

High Speed Rail Solutions' system safety engineering services are conducted in accordance with the requirements of the Common Safety Method for Risk Evaluation and Assessment (CSM RA) Regulations and CENELEC standards EN50126, EN50128 and EN50129.


We are providing these specialist services to a variety of clients to demonstrate that their systems and projects are being safely integrated into the existing railway network.


We know what it takes to ensure that projects receive supportive Safety Assessment Reports from independent Assessment Bodies and Independent Safety Assessors; subsequently leading to signed Declarations of Control of Risk, endorsement from System Review Panels and Authorisation for Placing into Service from National Safety Authorities (e.g. the ORR in the UK).

We have helped our clients with:

  • Project Authorisation Strategy development
  • System Definition development
  • System Context Diagram development
  • CSM RA Significance assessments, including stage work assessments
  • Planning of System Safety activities
  • Hazard Record development and management
