13 Railway Group Standard Signalling Works Testing Date February 1995 Part B Page B1 of 38 1 Purpose 2 Scope 3 Definitions 4 Objective of Testing 5 Testing Management This standard sets out the mandatory procedures necessary to ensure that new signalling installations and alterations to existing installations are independently tested in a manner which assures their safe operation and compliance with design before they are placed into service. The standard applies to all new signalling installations and to all alterations to existing installations where there is any change to the design. The standard for testing alterations where there is no change to the design is published as Railway Group Standard GK/RT0231 Signalling Maintenance Testing. The Appendices for this standard are arranged sequentially within the particular Part of the standard to which they are most relevant. Infrastructure Controller The organisation having control of the railway infrastructure. Maintenance Engineer The engineer contractually responsible to the Infrastructure Controller for the maintenance of the signalling system. The objective of testing is to ensure that the installation is in accordance with the design details supplied and that it performs to the system specifications and infrastructure controller s requirements. The installation must conform to statutory requirements and Railway Group standards. The assurance of the quality and completeness of the installation work is a separate activity for which testing staff must have evidence. However it is the responsibility of all staff to be vigilant for any shortcoming which might compromise the safety of the system and immediately advise their superior if they become aware of such a shortcoming. 5.1 Tester in Charge A person competent in accordance with Railway Group Standard GK/RT0101 Competence Standards for S&T Staff shall be nominated as being in overall charge of testing for each scheme. That person, designated Tester in Charge, shall be responsible for the organisation and satisfactory completion of the testing The Tester in Charge is responsible for the production and implementation of the testing plan, and any associated commissioning plans. The Tester in Charge may delegate the execution of these tasks to competent persons, but remains personally responsible for their completion The Tester in Charge shall ensure that each person involved is given adequate notice of, and is fully conversant with, their role in implementing the testing plan The Tester in Charge shall ensure that all testers involved in the work are fully briefed and are provided with written notes detailing what is to be done in each phase of the work. R A I L T R A C K B1

14 Railway Group Date February 1995 Withdrawn Document Signalling Works Testing Page B2 of Testing Strategy Each scheme shall have a Testing Strategy, written at the project specification stage, and forming part of the Project Specification For minor schemes this Testing Strategy may incorporate the Testing Plan A Testing Strategy is a written statement of the proposed testing methodology prepared on the basis of the specification, proposed layout and anticipated testing content of the scheme. It shall determine the extent of testing necessary, the resources required, the appropriate timescales and any preparatory testing required to confirm the feasibility of the proposed strategy. It must take account of the proposed commissioning strategy, including stageworks and possession arrangements. It shall include an assessment of the risks involved The Testing Strategy shall be approved by the engineer with overall responsibility for the project to ensure that it is compatible with the proposals for Signalling Design and Installation, and the work of the other infrastructure disciplines The Testing Strategy shall be kept up to date during project development and must identify the resources necessary for scheme implementation Following the authorisation of the scheme the Testing Strategy is the basis from which the Testing Plans and Commissioning Plans, including stagework, are to be developed The Testing Strategy shall consider the elements shown in Appendix A1 and include those which are appropriate to the project. 5.3 Testing Plan Each phase of the project shall be supported by a written Testing Plan. The Testing Plan must detail each testing activity to be undertaken. The Testing Plan shall state who is Tester in Charge and who is in overall charge of the scheme. The Testing Plan shall name the leading testers and clearly define the responsibilities and authorities of each. The Testing Plan shall be prepared sufficiently far in advance as to enable arrangements to be made for the safe working of trains The Testing Plan shall identify the resources necessary to implement the Testing Strategy. Responsibility for the procurement of sufficient competent testing staff and other necessary resources rests with the Tester in Charge The Tester in Charge may delegate the preparation of sections of the Testing Plan to competent persons The Testing Plan shall specify a satisfactory method of recording and certificating tests. The method and identification of check marks on plans, diagrams and control tables shall be defined before the work commences in accordance with examples contained in Appendix C. The diagrams must be signed in accordance with Appendix E. B2

15 Railway Group Standard Signalling Works Testing Date February 1995 Page B3 of The Testing Plan shall be independently checked by a competent person. The master copy shall bear the signatures of both the preparer and independent checker, one of whom must be the Tester in Charge. Controlled copies of the checked Testing Plan and any subsequent amendments, excluding any Check Lists and Test Certificates, shall be issued to named addressees only. The master copy shall be retained by the Tester in Charge The checked Testing Plan shall be issued sufficiently far in advance of any testing activity to ensure that all staff concerned are able to familiarise themselves with their testing roles and responsibilities before commencing work. This does not apply to the testing of off site prewiring. When it is necessary to undertake testing while the design for other parts of the project is incomplete, an interim Testing Plan must be issued Amendments to the Testing Plan are at the discretion of the Tester in Charge (or competent person delegated by the Tester in Charge). If the amendment alters the requirements of the Testing Strategy, the engineer with overall responsibility for the project shall be advised of the amendment. Amendments shall be recorded and must, where possible, be independently checked The Testing Plan may incorporate the Commissioning Plan; however, in many schemes it is impractical to separate out all the parts of the Testing Plan to be completed in particular commissioning periods without making numerous amendments to the Testing Plan. To overcome this a separate Commissioning Plan shall be written in these cases, which details the work necessary for those commissioning periods The Testing Plan shall consider the elements shown in Appendix A2, and include those which are relevant to the project. 5.4 Commissioning Plan The Commissioning Plan shall be prepared as soon as the split of work between preparatory testing and testing to be completed during the commissioning period is decided. It shall be prepared sufficiently far in advance of the proposed commissioning date to enable arrangements to be made for the safe working of trains during the commissioning period The Commissioning Plan shall be prepared jointly by the Tester in Charge and the engineer responsible for the installation work (or their delegated representatives) and include all the activities to be co ordinated The Commissioning Plan shall be independently checked by a competent person. The master copy shall bear the signatures of both the preparer and independent checker, one of whom must be the Tester in Charge. Controlled copies of the checked Commissioning Plan and any subsequent amendments, excluding any Checklists and Commissioning Certificates, shall be issued to named addressees only. The master copy shall be retained by the Tester in Charge The checked Commissioning Plan shall be issued sufficiently far in advance of any testing activities to which it relates to ensure that all staff concerned can familiarise themselves with their testing roles and responsibilities.

16 Railway Group Date February 1995 Page B4 of 38 Withdrawn Document Signalling Works Testing 6 Staffing The Commissioning Plan shall consider the elements shown in Appendix A2 and include those which are relevant. 5.5 General The format of these strategies and plans will depend on the scale and nature of the work, but they shall, as a minimum clearly indicate the extent of the testing necessary and the allocation of testing responsibilities to all persons involved The Tester in Charge shall carry out checks to satisfy himself that the testing is being carried out in accordance with the standards, and with the testing and/or commissioning plans. 5.6 Co ordination with Railway Operations Before testing commences at sites containing signalling equipment which is in use, the engineer responsible for the maintenance of the equipment shall be informed of the extent and programme of work At the commencement of each period of work at sites containing signalling equipment which is in use the tester shall inform the signalman of the intended work, its likely duration and the means of contacting the testing staff Before any period of work during which it is intended to carry out testing on equipment which forms part of, or is connected to, a signalling system which is in use: arrangements shall be made to ensure the safety of the railway in accordance with the Rule Book When the site is to be left unattended, details of any alterations to working equipment shall be left available for reference by maintenance staff and the engineer responsible for the maintenance shall be informed of the arrangements made Testing activities shall be arranged so that they do not prevent maintenance staff gaining access to working equipment. 6.1 Competence Testing staff shall have documented proof of competence in accordance with Railway Group Standard GK/RT0101 Competence Standards for S&T Staff Testing staff shall have been authorised by or on behalf of the infrastructure controller to undertake the testing work The Tester in Charge shall be satisfied that all staff on testing duties are competent and authorised to carry out the roles to which they are allocated in the Testing Plan. 6.2 Independence Independence of testing must be achieved. Staff who have participated by direct preparation, direct advice or direct control of that particular design or installation, shall not assume any testing responsibilities for such work. Such staff may, however, undertake testing responsibilities for any other part of the project in which they have had no direct involvement Staff who have had a direct involvement with the design and cannot therefore demonstrate the necessary independence may only act in an assisting role. B4

17 Railway Group Standard Signalling Works Testing Date February 1995 Page B5 of 38 7 Documentation and Certification Care must be exercised, when deploying staff to work in an assisting role to ensure that, if such staff are to assist other staff over whom they normally exercise managerial responsibility, they are not placed in a situation where the independence of the testing might be compromised. 7.1 Design Details A complete set of approved plans and independently checked diagrams must be provided for the exclusive use of testing staff The copy of the Design details provided for the use of testing staff shall normally be printed on Pink paper The production, issue, format and version control of all plans, diagrams and data shall be in accordance with procedures specified in Railway Group Standard GK/RT0201 Signalling Design Production Where it is necessary to carry out the changeover of equipment in a series of specific phases during a particular stage of the work, the test copies for that stage shall clearly indicate the work to be done in each phase, in accordance with the Signalling Design Standards. The Tester in Charge shall agree the method of presentation with the designer. The method of depicting the various phases shall be set out in the Test Plan Where the installation is to be returned to service between stages of the work, separate test copies shall be issued for each stage A closure list showing the totality of the design details issued shall be sent to the Tester in Charge Once diagrams have been issued to testing staff any required modifications shall only be produced as an approved modification in accordance with procedures specified in Railway Group Standard GK/RT0201 Signalling Design Production. Before issuing such diagrams or modification sheets the Design Office shall advise the Tester in Charge and obtain a Test Log number for each modification Minor modifications to design which are found to be required during commissioning may be undertaken by on site competent staff not involved in the testing of that part of the installation. Before installing such modifications there shall be an independent design check by a competent person whose independence has not been compromised by involvement in the design, installation or testing for that part of the work. Modifications prepared in this manner shall be forwarded, as soon as possible, to the relevant design office for approval and inclusion in the final records. Note: A list of plans, diagrams and other details that may be required are shown in Appendix A3. R A I L T R A C K B5

18 Railway Group Issue Two Date February 1995 Withdrawn Document Signalling Works Testing Page B6 rev of Record of Testing The testing copy of the design details shall be the primary auditable record of testing achievement Each tester shall record their name, signature and the test date in an Activity Box (Appendix E) in the colour to be used to record the tests Each tester shall use a colour for their work that does not appear on the test copies when testing starts Individual tests shall be recorded on the test copies using check marks specified in the testing plan (Section B5.3.4) All test values shall be recorded on the maintenance record card/sheet as specified by the infrastructure controller, during or on completion of the work. 7.3 Certification of Testing Certificates of test and conformity shall be produced covering all equipment Certificates shall be produced on distinctively coloured paper (normally Pink) Test Certificates shall be prepared prior to the commencement of testing, their format being dependent upon the nature of the testing involved The Tester in Charge shall: (1) Produce a Master Certificate. (2) Be responsible for the production, issue and control of all certification. (3) Be responsible for documenting any non compliances with standards found during testing and any deferred Test Logs Management of certification is specified in Section B.7.6. (A suggested format for certification is shown in Appendix B.) The Master Certificate shall be signed by the Tester in Charge. 7.4 Test Logs Test Logs shall be produced for any queries, disagreements or deficiencies For every Testing Plan a formal Test Log Index, which may be subdivided, shall be prepared The Tester in Charge shall be responsible for the index and specify in the Testing/Commissioning Plan where the index(es) shall be located Each Test Log shall have a unique identity number in a continuous sequence taken from the index(es) Any deferred Test Logs shall be dealt with in accordance with Section B The Test Logs shall be made up in triplicate. The top copy Green, the middle copy Yellow and the bottom copy Pink. B6rev

19 Railway Group Standard Signalling Works Testing Date February 1995 Page B7 of The Tester shall initially fill in the Test Log detailing the problem as they see it. The problem shall be clearly identified and, where necessary, shall guide the person from whom the response is expected as to where the problem lies. Where the necessity to guide becomes too involved, or if a circuit design query is of a complex nature, the testing of a resulting modification may need to be carried out by a tester independent of the initial testing which highlighted the problem Generally, each item shall be entered on a separate Test Log. Items of a common nature may only be included on one Test Log, with the agreement of the Tester in Charge After a Test Log is filled in, the Green and Yellow copies shall be passed forward to the relevant designer/installation group and the Pink copy filed with the index. The relevant group shall enter a response, complete with Mod Number if appropriate, and retain the Yellow copy for their records. The Green top copy shall be returned, complete with any Mod Sheets to the Tester in Charge All resulting modifications shall be subject to a retest. Such retesting must include all parts of the installation which could have been affected by the alteration. If the action is satisfactorily retested, then the Green copy shall be signed by the Tester and replace the Pink copy with the Green Copy and the Index endorsed to show that Test Log item completed. If the action does not satisfy the Test Log item, the Green copy shall be endorsed as such by the Tester and the index endorsed to show that a new Test Log has been generated to progress the problem. Note: A flow chart of the Test Log cycle and a suggested format of the index and Test Log sheets are shown in Appendix D. 7.5 Check Lists Check lists are an aid to testing and may be used as necessary to: (1) Summarise physical progress. (2) Collate certification progress. (3) Aid the Tester. (4) Record Mod state of equipment. 7.6 Management of Certification Before the installation is handed over to the infrastructure controller to be placed into service the Tester in Charge is responsible for: a) The collection and inspection of all Test Logs to ensure that they comply with one of the following categories: Completed to the satisfaction of a suitably competent tester. Not completed, with outstanding items considered to be undesirable but not inherently unsafe. R A I L T R A C K B7

20 Railway Group Issue Two Date February 1995 Withdrawn Document Signalling Works Testing Page B8 rev of 38 Such Test Logs may be deferred for later rectification when the Tester in Charge and the infrastructure controller or his nominated representative agree that the Test Log item is not inherently unsafe; and are satisfied that there is an action plan which includes: the method of rectification, the completion date and a monitoring and progress review strategy. Completed to the infrastructure controller s requirements; but endorsed to the effect that in the tester s professional engineering judgement concerns remain over the interpretation and application of signalling standards to the installation under test. The Tester in Charge shall ensure that the infrastructure controller is aware of the details of endorsed Test Logs, and that the infrastructure controller formally accepts the responsibility. b) The collection and collation of all plans, diagrams and certification, and for ensuring that all such documents have been received and are properly annotated. Where it is not practicable to return completed documentation to the Tester in Charge prior to the handover, the Tester in Charge must be positively notified, in writing where possible (fax acceptable) by the tester responsible for the activities documented. The completed documentation must be returned to the Tester in Charge within 72 hours of such notification When all Test Logs and documentation have been collected and dealt with as required in Section B7.6.1 the Tester in Charge shall certify that the testing is complete, using the Master Test Certificate. The installation may then be signed into use by the infrastructure controller or, where the infrastructure controller has delegated the responsibility, by the Tester in Charge All test results shall be entered on the forms or other maintenance records, specified by the infrastructure controller, during or on completion of the work and be handed over for maintenance use The set of plans and diagrams used for testing shall be returned to the originating design office for all Test Logs modifications and layout changes to be correlated into the final records On completion of the record update, the set of plans and diagrams used for testing and the completed testing certification shall be returned to the infrastructure controller or his designated engineer. The location to which these plans were sent must be recorded on the relevant correspondence file. A copy of the Master Test Certificate must also be kept on the same file All testing copies of the plans and diagrams and all certification sheets and top copies of the Test Logs must be retained by or on behalf of the infrastructure controller.

28 Railway Group Issue Two Date February 1995 Page B16 of 38 Withdrawn Document Signalling Works Testing Appendix C1 - Presentation C1.1 Information For alterations to existing installations a two colour code system is to be used as follows: Green to identify existing wires / equipment to be recovered. Red to identify new wires / equipment to be installed. (See App Figure 2 for colour convention.) Where alterations involve large scale recoveries or modifications to existing circuits, consideration should be given to the production of two copies of each drawing, showing the alterations as follows: First copy - showing existing wires/equipment to be removed (green). Second copy - showing new wires/equipment to be installed (red). (See App Figure 2 for colour convention.) Where recoveries are such that a complete drawing becomes redundant, then the drawing must bear a cross, coloured green, through the sheet (ie, it is not necessary to colour each individual redundant circuit). Where an existing circuit is transferred from one drawing to another then both drawings must bear a suitably coloured note to that effect quoting the relevant drawing numbers. When a new drawing is required to be produced for an existing installation and the drawing depicts all new work to be installed, the drawing must bear the following: ALL NEW WORK coloured red. Where it is required to signify that a book of drawings depicts all new work, it will only be necessary for the index sheet to be endorsed as follows: ALL NEW WORK coloured red. When stageworks are involved, a separate set of drawings must be produced for each stage, irrespective of the timescale between stages. Each stage must be clearly identified on each drawing or book of drawings. Design details produced for testing purposes must be printed on pink paper, or alternatively, be identified by a coloured patch (see Appendix C2). Each new drawing or master print of the design details must bear the producer s printed and signed initials in the signature panel. Where the design details are to be carried out on existing drawings, then each drawing affected, together with subsequent duplicate copies, must be stamped with the relevant signature panel which must contain the producer s printed and signed initials. Note: The source of this Appendix is GK/RT0201, Signalling Design Production. B16

31 Railway Group Standard Signalling Works Testing Date February 1995 Page B19 of 38 Appendix C2 - Method and Identification of Check Marks (one drawing situation) It is essential that staff involved in the testing process understand the check marks used on the drawings as the testing proceeds. This Appendix outlines the standard check marks to be used during testing. It is impossible to be totally comprehensive. If a test is undertaken for which no check mark is detailed, then the tester will invent one. When a novel mark is used, its meaning shall be explained in the Testing Plan and/or on the diagram used for testing. If the symbol is to be used commonly throughout a scheme, it may be drawn and explained upon the diagram cover or upon a specially issued explanation sheet to be issued to all affected testers, with a copy attached to the diagrams. This Appendix contains samples of the Wiring Diagrams (showing new and old wiring on the same diagram) which are applicable to Signalling Works Testing. R A I L T R A C K B19
