User information This Network Rail standard contains colour-coding according to the following Red–Amber– Green classification.

Red requirements – no variations permitted

• Red requirements are to be complied with and achieved at all times. • Red requirements are presented in a red box. • Red requirements are monitored for compliance. • Non-compliances will be investigated and corrective actions enforced.

Amber requirements – variations permitted subject to approved risk analysis and mitigation

• Amber requirements are to be complied with unless an approved variation is in place. • Amber requirements are presented with an amber sidebar. • Amber requirements are monitored for compliance. • Variations can only be approved through the national variations process. • Non-approved variations will be investigated and corrective actions enforced. Green guidance – to be used unless alternative solutions are followed

• Guidance should be followed unless an alternative solution produces a better result. • Guidance is presented with a dotted green sidebar. • Guidance is not monitored for compliance. • Alternative solutions should be documented to demonstrate effective control.

Compliance This Network Rail standard/control document is mandatory and shall be complied with by Network Rail Limited and its contractors if applicable from 31st May 2018. Where it is considered not reasonably practicable1 to comply with the requirements in this standard/control document, permission to comply with a specified alternative should be sought in accordance with the Network Rail standards and controls process, or with the Railway Group Standards Code if applicable. If this standard/control document contains requirements that are designed to demonstrate compliance with legislation they shall be complied with irrespective of a project’s GRIP stage. In all other circumstances, projects that have formally completed GRIP Stage 3 (Option Selection) may continue to comply with any relevant Network Rail standards/control documents that were current when GRIP Stage 3 was completed. NOTE 1: Legislation includes Technical Specifications for Interoperability (TSIs). NOTE 2: The relationship of this standard/control document with legislation and/or external standards is described in the purpose of this standard.

Disclaimer In issuing this standard/control document for its stated purpose, Network Rail Limited makes no warranties, expressed or implied, that compliance with all or any standards/control documents it issues is sufficient on its own to provide safety or compliance with legislation. Users are reminded of their own duties under legislation. Compliance with a Network Rail standard/control document does not, of itself, confer immunity from legal obligations. Where Network Rail Limited has granted permission to copy extracts from Network Rail standards or control documents, Network Rail Limited accepts no responsibility for, nor any liability in connection with, the use of such extracts, or any claims arising there from.

This disclaimer applies to all forms of media in which extracts from Network Rail standards and control documents might be reproduced.

1 Purpose This document contains the index to the Signal Maintenance Testing (NR/SMTH)

The SMTH provides a maintenance testing regime for the replacement or installation of signalling equipment that does not affect the application logic of the system or, the controls of the system that have previously been tested to signal works testing.

2 Scope Signalling equipment that is replaced or renewed on a like for like basis under corrective maintenance, temporary design as a result of an incident or engineering works and minor signalling renewals that do not affect the application logic of the system or, the controls of the system that have previously been tested to signal works testing.

3 Definitions Definition Meaning Application Any technology based method that configures a product so as to Logic provide site specific command and control instructions. Application logic includes: a) mechanical logic (e.g. in lever frames); b) electro-mechanical logic (e.g. in relay interlocking); c) electronic switching or code (e.g. in electronic interlocking, telephone concentrators or cab secure radio); d) any combination of the above.

Maintenance Known also as Like-for-Like replacement. The removal and Testing restoration of a product in a previously operational system, where the work does not change the configuration or functionality of the system. Engineering details are not provided for the work, and instead the existing infrastructure records are used as the reference documents. Typically, such work is carried out to replace/repair defective or life- expired products. The work may involve replacing the original item of equipment with the exact same new or refurbished item or replacing it with a differant make that is identical in all areas (apart from visual appearance) to the original. Work undertaken by maintenance testing shall not exceed the definition of extensive and simultaneous.

Definition Meaning Works Works testing consists of the construction/installation of new or Testing modified products and/or application logic where the work changes, or potentially changes, the configuration or functionality of the system. The work is carried out in accordance with engineering details supplied for the purpose. For the purposes of this document, the definition includes: a) the installation of totally new systems; b) the alteration of existing systems; and c) the abolition (also known as ‘recovery’) of existing systems.

Maintenance An individual with the competencies and authority to work Tester appropriate to the required work assigned to specify and/or perform the tests necessary to ensure that the physical implementation of a design is correct and meets all the specified test and acceptance criteria.

Test Plan A test plan comprises any document or suite of documents that determines and defines the processes, resources and specifications required for the testing and commissioning of a product at a specific location.

4 Index of NR/SMTH The indexes show the latest (current) issues of the individual SMTH documents. Updated NR/SMTH documents take time to introduce into service due to briefing and --``,,``,`,,`,```,,``,,````,,,`,-`-`,,`,,`,`,,`--- the requirement to implement at the correct point in the maintenance cycle.
