Description

The scope involves the renewal and replacement of existing 48V DC signalling Power Supply Units (PSUs), with modern Network Rail-approved equivalents. A total of 16 PSUs are to be replaced across seven locations. These units provide essential power to axle counter evaluators controlling Up and Down lines. The works are intended to ensure the continued reliability, safety, and resilience of the signalling system in line with the Windrush Line core renewal strategy.
