Ely to Peterborough (E2P)/Anglia Signal Structures Modernisation (A2SM)

Global Rail Construction Limited (GRCL) has successfully completed its Lineside Civils and Rail Systems sub-contract scope with Principal Contractor AtkinsRèalis and client Network Rail on the Ely to Peterborough (E2P) / Anglia Signal Structures Modernisation (A2SM) project. 

The project aimed to renew life-expired signalling infrastructure but was postponed after achieving AFC design status. Whittlesea was identified as a critical area due to deteriorating infrastructure. Limited funds led to the creation of the A2SM project, which covered the following scope:

• Renew signal structures
• Modify mechanical interlocking
• Upgrade power systems
• Install new track circuits and IRJs
• Recover redundant equipment

The project objectives were achieved covering the extension of the life of existing infrastructure without service enhancements, improvement of reliability and maintainability of signalling assets, ensuring compliance with Network Rail standards and safety requirements.

GRCL’s project deliverables covered the civils and rail systems scope for the renewal of signals (Whittlesea: W3, W4, W5, W23, W26; Manea: M1, M2, M3, M21, M23; March: MS933, ME8, MS32, MSA, MS1/2, MS9; Kings Lynn: KL8 including signal box and panel modifications), updating signalling scheme plans and block shelf diagrams, and delivering compact PSP installations and LV power upgrades. The team supplied all health & safety files and as-built documentation and were responsible for the recovery and disposal of redundant equipment.

Due to financial constraints, the project was split into Year 1 and Year 2 scopes of work.
