This module states the requirements to be met when working on the overhead line equipment on 25 kV a.c. electrified lines.

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

To provide a consistent approach to working on or about 25 kV a.c. electrified lines, Train Operating Companies may, as best practice, apply this standard to infrastructure they control.

This Standard also includes:

• Work on or about 25kV electrified lines except areas undertaking the trial of the Single Approach to Isolations on 25kV a.c. infrastructure and Network Rail controlled infrastructure equipped with the 1500V d.c. overhead line system.

• 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).

Purpose

This module provides a consistent approach to working on the overhead line equipment of 25 kV a.c. electrified lines.

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).
