Network Rail Standards Updates

Approach / Solution

• Standards Review & Categorisation
  • Reviewed Network Rail telecom standards against ETCS implementation requirements on the East Coast Main Line.
  • Assessed each standard for relevance, currency, compatibility, conflict, and continued necessity.
  • Focused on impacts around legacy communications, cable standards, wireless frequencies, and interoperability.
  • Categorised proposed amendments into minor and major changes to define the standards update baseline.
• Technical Justification & Authority Review
  • Initially identified 12 standards as requiring major change.
  • Prepared the technical justification for each proposed update and presented the recommendations to the technical authority.
  • Worked through challenge, clarification, and refinement with the authority, resulting in 8 standards being confirmed for major update.
• Risk Assessment & Governance
  • Carried out risk assessment on the agreed changes to support safe and justified progression.
  • Raised the required TCCF documentation and presented the proposed logic to the technical change committee.
  • Engaged with relevant stakeholders and SMEs to explain the rationale, address concerns, and secure agreement for update.
• Process Development & Commercial Support
  • Created a formal process to justify the time required to review and update Network Rail standards.
  • Presented the process to the client as a structured basis for understanding the scope and effort involved.
  • The process was subsequently adopted by other disciplines and helped maintain consistency and accuracy when proposing fixed-price variations.

• Reviewed and rationalised the telecom standards baseline supporting the East Coast Main Line ETCS programme.
• Identified 12 standards initially requiring major change, with technical authority review refining the final scope to 8.
• Enabled 8 Network Rail telecom standards to be updated so that ETCS could be incorporated safely and effectively.
• Supported the risk assessment, TCCF, and technical change committee process required to progress the updates through governance.
• Created a repeatable process for estimating and justifying standards update effort, which was adopted by other disciplines.
• Improved consistency and commercial accuracy when preparing fixed-price variations.
