Existing proposals envisaged piecemeal upgrades to signalling and train control spread out over 50 years, creating a patchwork of different systems that would operate side by side for decades.


By accelerating the national deployment of proven digital technology on a region-by-region basis over 25 years, Digital Railway maximises the economic benefit to Great Britain, delivers it more quickly, and reduces the costly disruption of conventional upgrades needed to meet demand in the meantime.

Digital Railway’s partners in industry and government are working together to define a robust delivery plan that applies lessons from major infrastructure upgrades. For example, the Programme integrates key elements of the change needed into a common national strategy – from driver training, to cab fitment, to cyber security. Consultation will continue throughout 2016 to confirm the best possible timetable for delivering different elements of the plan to deliver a digital railway by 2040.

We have supported the Digital Railway Development Programme in;

  • Defining the Engineering lifecycle, including associated engineering strategies, plans and processes (such as System-of-Systems Management Plan, Systems Engineering Management Plan, Requirements Management Plan, Verification and Validation Management Plan, Interface Management Plan)

  • Elicitation and capture of Digital Railway requirements (Business Requirements, Stakeholder Requirements, System Requirements)

  • Developing the operations concept

  • Engineering maturity and status assessment at programme and constituent project level
