- East Coast Main Line (GNGE) is expected to deliver more services and faster journey times by improving the efficiency and flexibility of the railway between Peterborough and Doncaster and by undertaking a series of renewal works.
- The works aim to improve safety, increase capacity, bring better performance and reliability and reduce heavy maintenance for at least a 15-year period.
- GNGE will improve 61 level crossings, place over 80 miles of track, increase train speeds up to 60-75mph, renew 57 bridges and install modular signalling.
- Effective capture of requirements as the basis of progressive assurance.
- Delivering an implementable solution within the resource constraints.
- Providing quality and timely outputs within the resource constraints.
- Requirements management, using a DOORS database, involved the verification and validation of the GRIP 3 programme requirements specification (PRS).
- Processes were developed to capture evidence against the PRS to support progressive assurance for individual works, allowing early progression to GRIP 4 while ensuring compliance for all elements along the route.
- System integration included developing an integrated workbank, a progressive assurance procedure, an integrated programme as well as design reviews.
