Cross Rail Power Migration

Scope of work: Softech has produced Signalling design in connection with migration of Signalling Power supplies from class 1 to the class 2 system with the series of discreet design packages for signalling location suites which are currently fed at BX650 supply from IT class 1 radial feeders (non-compliant to the requirements of BS7671) in the area between Bethnal Green and Shenfield on Great Eastern Railway (ELR LTN1).

Design for the upgrade of Signalling power supplies has been produced for approximately 150 locations for Network Rail and are being commissioned in 7 packages. New PSPs (Principal Supply Point) have been installed at 6 key points on LTN1 Great Eastern mainline. New FSPs (Functional Supply Points) installed adjacent to existing Signalling location suites to upgrade the power supply.
Signalling design packs produced to support the migration of Power Supply, depicting the recovery of power cables and providing new power supply cables along with earthing arrangements.
