scope:

This module states the general requirements for working on or about Overhead Line Equipment including responsibilities, a description of the electrification systems, the danger that can arise from live overhead line equipment and how to communicate with the Electrical Control Operator (ECO).

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 to infrastructure they control.

This module 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 a 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 supports a consistent understanding of working on or about Overhead Line Equipment.

NOTE: Further requirements for working on or about the electrified lines and for communication are contained in the Rule Book Modules AC, HB16 and G1 (GE/RT8000/AC, GE/RT8000/HB16 and GE/RT8000/G1).
