scope:

The TWIs may be applied by anyone who has been assessed and is deemed competent under the Network Rail competency management programme and is working on the track asset controlled by either:

a) a standard maintenance document (e.g. SMP, Method Statement, Work Instruction); or

b) an approved Method Statement on a renewals or project site.

The details within the TWIs may be used as the basis for "tool-box talks" provided that the briefer meets the competency assessment criteria.

The TWIs should not be applied or interpreted in stand-alone mode.

Purpose

This Guidance Note provides the index and version control to the Track Work Information Sheets (TWIs) to be used in connection with Standard Maintenance Procedures, Method Statements, Work Instructions and Track Training Framework training documentation.
