E&P, SPS and OLE Framework for Southern Region

Network Rail intends to establish a framework for the delivery of Electrical & Plant (E&P) Minor and Reactive Works, Signalling Power Supply (SPS) Minor Works and Renewals, and Overhead Line Equipment (OLE) Maintenance support services across the Southern Region.

The framework will provide access to suitably qualified suppliers to undertake planned, reactive, emergency and renewal activities associated with the maintenance, renewal and operational support of rail infrastructure assets.

The E&P scope encompasses maintenance, minor works and reactive interventions relating to E&P assets and systems across the Southern Region, including but not limited to:

-Traction power distribution systems.

-Non-traction power distribution systems.

-Points heating and conductor rail heating systems.

-Low Voltage (LV) systems, including Distribution Network Operator (DNO) supplies.

-Lighting and domestic electrical systems, including station, lineside, outdoor and level crossing lighting.

-Signalling Power Supply (SPS) Minor Works and Renewals

The SPS scope comprises planned and unplanned renewal, replacement, modification and maintenance activities associated with signalling power supply infrastructure, including but not limited to:

-SPS cables (230V to 650V) and associated cable routes.

-Functional Supply Points (FSPs) and other structures housing SPS equipment.

-SPS cable and fault monitoring systems and associated equipment.

-Power supply schematic design amendments and modifications.

-SPS sub-fusing works.

-SPS network splitting and modification works using Distribution Interface Transformer Assemblies (DITAs).

-OLE Maintenance Support Services

The OLE scope comprises the provision of specialist labour and plant resources to support maintenance and operational activities on Overhead Line Equipment infrastructure, including but not limited to:

-OLE isolation teams and nominated persons.

-Engineering Supervisors.

-Points Operators.

-Barrier Persons.

-DET Communications support.

The framework is expected to support the safe and efficient delivery of maintenance, renewal and reactive works across the Southern Region rail network and may be utilised for both planned programmes and emergent operational requirements.
