AmcoGiffen and its supply partners carried out design surveys that identified recommendations for improving the maintainability and resilience of the LV distribution system. It also highlighted the need to future-proof the system via the latest security, BMS and Intelligent Infrastructure & Human Machine Interfaces (HMI) to ensure the continuity of service to the Network Rail remote monitoring facility.Some of the engineering deliverables AmcoGiffen were tasked with included:Production of a robust test and commissioning strategyReplacement of the 11000/400v transformer shunt trip break glass units Thames Valley Signaling Centre (Network Rail).'
