This module states the requirements for constructing overhead line equipment, working on new Overhead Line Equipment and dismantling existing Overhead Line Equipment.

It is applicable to Network Rail personnel and to Network Rail’s contractors.

To provide a consistent approach to working on or about Overhead Line Equipment, Train Operating Companies may, as best practice, apply this standard in full on infrastructure they control.

This Standard also includes:

• Work on or about any future sections of electrification on Network Rail controlled infrastructure and areas required to adopt a process for securing points of disconnection to form points of isolation to use the Supplementary Isolation Process (Module X).

• Planning of isolations, testing and earthing of overhead line equipment on Network Rail controlled infrastructure equipped with 750V d.c. overhead line system (Sheffield Tram Train - Module Y).

• Planning of isolations, testing and earthing of overhead line equipment on Network Rail controlled infrastructure equipped with 1500V d.c. overhead line system (Sunderland Metro Systems Operating Area – Module Z).

Purpose 

This module provides a consistent approach for dealing with new Overhead Line Equipment, Overhead Line Equipment under construction and redundant existing Overhead Line Equipment being dismantled so that the general requirements for working on or about Overhead Line Equipment are not prejudiced. 

NOTE: Further requirements for working on or about the electrified lines are contained in the Rule Book Module AC (GE/RT8000/AC and Handbook HB16 (GE/RT8000/HB16)).
