scope:

This modular standard provides:

• electrical safety requirements for persons working on or near to 3rd rail d.c. electrified lines in the Liverpool area that will enable them carry out their duties without risk of danger from the conductor rail to themselves or other persons and
• railway operating and safety requirements that apply specifically to the underground railway in the Liverpool area and
• requirements for working of trains on the 3rd rail DC electrified lines and associated depots and sidings in the Liverpool area

Further requirements are contained in Rule Book Module DC (GE/RT8000/DC).

Purpose

This modular standard updates previously published instructions for 3rd rail d.c. electrified lines in the Liverpool area to:

• enable use of equipment for delivering conductor rail isolations more safely and more rapidly and
• incorporate previously authorised changes that were published separately as Letters of Instruction and
• present them in an approved format that clarifies where variation may be permitted.
