Crossrail Boundary - Systems Review

Crossrail represents a £16bn investment in London’s transportation network, providing an essential east-west link through central London. CPC was engaged to undertake a structured review of the key boundary interfaces between Network Rail’s existing signalling systems and the proposed signalling systems for Crossrail.

We undertook a review of the signalling systems, identifying complexities, key risks, possible interface issues, responsibilities and providing advice on suitable mitigations.  For each interface
we provided scenario-based reviews around projected service patterns, available capacity, and normal operations (i.e. non-degrades modes) to understand compliance with the project goals, and identified key constraints.  We also defined the technical scope and methodology during migration stages from the legacy system to the new system.
