scope:

This standard applies to the asset management of all EP assets. Certain clauses also apply to the introduction of new EP assets to the rail network.

Line of sight to asset management core principles and Network Rail objectives

All asset management interventions defined in this policy are aligned to the principles defined in the Network Rail asset management policy and to the objectives defined in the Network Rail asset management strategy (see figure 1). They:

a) are based on minimising whole life, whole system costs;

b) are underpinned by appropriate facts from enhanced information;

c) define the most appropriate approach to asset maintenance inspection and renewal, supported by reliability, availability, maintainability and safety specifications;

d) define a risk-based approach to determining intervention requirements to specify levels of reliability;

e) define resilience requirements to a specified range of weather conditions, taking account of emerging knowledge of climate change; and

f) define how sustainable development requirements are to be addressed.

The EP asset management policy sits at stage 3 in the Network Rail asset management framework shown in figure 2, which provides line of sight between Network Rail's high level objectives and the execution of work. A review and learning feedback supports continuous improvement.

Purpose

The purpose of the Electrical Power (EP) asset policy within Network Rail is to provide reliable and safe operation of the network to:

• Provide for the safety of employees, contractors, users of the infrastructure and third parties,

• Meet and maintain statutory obligations,

• Optimise the life and performance of assets and the network,

• Maintain quality of service by minimising disruption to customers.

This standard contains the specific requirements that enable the objectives set out above to be met. Prior to issue of this standard, the requirements were set out in Annex 1 - Policy implementation requirements and guidelines (April 2018) to the Electrical Power Asset Policy.
