Railways first, and a lot besides

Most of my recent work is on railways and stations, where new systems have to be built, tested, and brought into use around a live operation. Before that came defence, aerospace, space, and air traffic management, each with its own demands for safety and dependability.

HS2 Euston

Client
MaceDragados Joint Venture
Period
2023 to date

The Euston campus is being transformed around HS2's new London terminus, alongside the redevelopment of the Network Rail and London Underground stations: one site, three infrastructure managers, each with its own requirements and standards. I'm guiding the project's requirements management, technical assurance, and systems engineering, and updating its engineering processes.

  • Re-architected the project's engineering management system and wrote its overarching management plan
  • Set up handover arrangements for the London Underground traction substation works
  • When the scope grew to cover the whole Euston campus, set up its requirements management framework, and led the requirements work that merged several stakeholders' needs into one integrated, consistent, and verifiable specification
  • Responding to the campus-wide scope, developed an assurance regime to meet the combined requirements of HS2 Ltd, London Underground, Network Rail, and other stakeholders

Bank Station Capacity Upgrade

Client
Dragados
Period
2014 to 2025
Value
£650m+

The upgrade added a new Northern line running tunnel and platform, new passageways, and a new station entrance, all constructed while Bank stayed open. It was completed and handed over in 2025. I led the systems engineering team through detailed design, then also took on systems engineering and technical assurance through construction and handover.

  • Led systems integration, requirements management, verification and validation, and safety, RAM, EMC, and human factors engineering
  • Wrote and managed the Railway Migration Plan, which defined how the station was brought into use through three intermediate operational configurations
  • Developed the technical integration strategy that made that staged migration possible
  • Introduced a new approach to managing takeover into operation and maintenance
  • Built DOORS-based systems to track around 4,000 engineering documents and deliverables through to acceptance

Intercity Express Programme

Client
Hitachi Rail Europe
Value
£4.5bn

Supported Hitachi in managing requirements and assurance for the new fleet. I designed and introduced an information management environment using IBM DOORS and Rational Publishing Engine, then trained and mentored Hitachi's engineering team to run it.

West Coast Route Modernisation

Client
Network Rail
Value
£9bn

As systems design and integration manager, I redeveloped and applied the programme's systems engineering management processes. I also led the team that captured and developed the client's requirements, produced the high-level system design, specified the requirements for the programme's major delivery teams, and provided overall system-level assurance.
