This specification applies to all positive conductor rails and associated cables forming part of the electrical traction supply system.

Purpose

The purpose of this standard is to specify the planned periodic maintenance for positive conductor rail and associated cables on DC conductor rail traction power electrified lines.

This standard controls the risks associated with asset failures and non-compliance with regulatory requirements. The specified periodicity optimises the level of business impact, balancing the risks and costs associated with planned and unplanned interventions.

This document is to be used in conjunction with any other relevant, Network Rail maintenance standards, such as NR/L3/ELP/27250 – Conductor Rail Equipment Working Instructions.
