scope:

This specification applies to all Network Rail signal infrastructure.

This specification provides information relating to the establishment of effective equipment inspection and staff surveillance regimes to ensure that all signal infrastructure systems and equipment and the associated working practices remain in a state suitable to allow the safe and reliable operation of trains.

The scope of this document is limited to signalling maintenance activities only, and includes component replacements (e.g. point machine renewals) undertaken by the maintenance organisation.

Installation activities are addressed in RT/E/S/10161. Competence of Works Testing staff is addressed in RT/E/P/14001, RT/E/S/14002 and RT/E/S/14003.

Purpose

This specification is intended to augment and amplify the responsibilities placed upon the infrastructure controller as stated in Clause 8.3 Railway Group Standard GK/RT0210.

As such, this specification sets out the principles and methods for the inspection and surveillance of signal engineering activities. This aim will be achieved by:-

• Applying a regime of signal equipment inspection thereby ensuring that the signal infrastructure retains conformity with the conditions of its approval and design

• Applying a regime of signal engineer staff surveillance thereby ensuring that the competencies of those working on the signal infrastructure are regularly monitored.
