1 Purpose The purpose of this document is to define the Signal Design and Technical Review requirements for MTM when performing an ARTO review of external designs.

The document shall also define the requirements and responsibilities of Contractors and the design documents they must produce in order for Metro Trains Melbourne (MTM) to undertake an ARTO Signalling Design and Technical review.

This document applies to all works on the MTM network affecting the signalling Infrastructure.

This procedure supersedes and replaces L1-NAM-PRO-001. Where other MTM processes and procedures refer to L1-NAM-PRO-001 this specification shall apply.

This procedure is not applicable when the design is undertaken in house by MTM. An ARTO review is not applicable for internal designs as MTM shall ensure their requirements are provided and met through the design process.

2 Scope It is imperative that all organisations have a clear understanding of MTM’s Design and Technical requirements and submit all the required documentation as listed in this procedure.

The requirements stated in this procedure apply to all signalling designs prepared by Contractors for use on the MTM network [either on behalf of MTM Projects, Infrastructure Delivery or other stakeholders such as the Public Transport Victoria (PTV), Level Crossing Rail Authority (LXRA), Melbourne Metro Rail Authority (MMRA)].

The design review must follow the Terms of Reference specified by MTM and shall provide assurance that all the requirements of the Accredited Rail Transport Operator’s (ARTO’s) Safety Management System, including operational and functional requirements and the appropriate standards, have been met.

This document should be read in conjunction with the latest MTM Design and Technical Review Procedure, document No. L1-NAM-PRO-002.

7 Approach The Rail Safety Act 2006 is clear that rail safety is a shared responsibility and the Contractors Design Office is fully responsible for their design, checking and verification. The ARTO is responsible for ensuring the Contractor produces designs that are safe and comply with recognised quality assurance processes.




The approach to be taken with a technical review is to consider the design based on MTM’s requirements, in particular the impact on both existing and future inspection, maintenance, safety and operational regimes. A ‘whole of life’ view shall be applied.

The MTM technical review is not a substitute for the design, checking and verification processes that form part of the production of signalling drawings. The MTM Review will, however, confirm that these have been satisfactorily performed by the Contractor.

The MTM Review will typically consider:

• Safety in design

• Maintainability

• Functional and Operational requirements

• Quality processes including design, check and verification

• Independence in the design process

• Competency of designers

• Compliance to standards, approvals and specifications

8 Contractors Mandatory Requirements The contractor shall ensure the following mandatory requirements are undertaken during the production of the signalling design prior to submitting to MTM for review. Evidence of such shall be supplied as part of the Design Review submission by the Contractor.

8.1 Equipment The designs shall utilise MTM type approved equipment only.

8.2 Competency All staff responsible for the design, checking, independent verification, installation and testing of signalling designs shall hold the relevant level(s) of competency as required by the MTM CMS to work independently.

All staff involved in the design, installation and testing of signalling designs that do not hold the relevant level(s) of competency for the tasks being undertaken shall be mentored by a person that holds the right level(s) of competency required by the MTM CMS for the task being mentored.

The mentor shall become the person responsible for that activity and shall be required to countersign all documentation associated with that activity.

Checkers under Mentorship shall hold a minimum competency of Level 2 in design and Level 1 in checking for the task(s) they are being mentored to check. Mentoring of independent verifiers shall not be permitted.




8.3 Mentoring A contractor wishing to utilise mentors in the production, installation and/or testing of their signalling designs shall provide MTM with the following prior to any mentoring activities taking place;

1. A copy of their mentoring process for approval

2. A list of their staff and the activities that they wish them to be mentored in

8.4 Correlation Prior to any design alterations, all signalling source records required to be modified are to be correlated against the actual wiring and equipment on site to check their accuracy. Should differences be identified then the source records shall be updated and independently checked in order to ensure the base documentation used for the design reflects what is out on site. Once completed one paper copy of all amended source documentation shall be provided to MTM Engineering.

8.5 Standard Waivers A Standard Waiver shall be obtained where the requirements of standards cannot be met.

8.6 Independent Verification All safety critical designs are to be Independently Verified as detailed in VRIOGS 012.1, section 5.0. MTM considers Signalling Arrangement Plans, Control Tables, Bonding, Power and Cable Running Plans, Fringe/Interface, Level Crossing and SER/Location circuits, ALDS, Axle Counter and CBI Architecture and application logic data to be safety critical design.

MTM reserve the right to request Independent Verification of other items of design if deemed necessary.

8.6.1 Verifier Independence for safety critical design verification is essential and must be demonstrated by the Contractor.

Typically, independence requires the Verifier to be engaged from an external company and for the design to be verified at an office external to where the design has been created.

It may be acceptable to undertake verification within the same company but with the Verifier located in a separate office having had no involvement in the design production. This arrangement must be pre-approved by the MTM Head of Engineering – Signals.

The Contractor must be able to clearly demonstrate that there is no association between the person(s) undertaking the design and/or checking of the design to be verified.




8.6.2 Verifier Certification The Verifier shall provide a verification report that includes certification from the Verifier that the (safety critical) design verified complies with the projects functional and operational requirements, is maintainable and conforms to the required standards (unless supported by a standard waiver). The Verifier shall also confirm that the design is safe to use for train operations on the MTM network.

8.7 Design Report The Contractor shall provide a comprehensive Signalling Design Report which includes certification that:

• the design complies with the projects functional and operational requirements;

• the design is maintainable:

• the design conforms to the required standards unless supported by a standard waiver.

The design report shall also contain any comment logs prepared by the checker and verifier during their checks. These logs shall detail the comments raised along with the designer’s response/actions and all logs shall be closed out to the satisfaction of the person(s) who raised them or their appointed delegate.

8.8 Application Logic Data Structure Manual (ALDS) An Application Logic Data Structure manual shall be produced and submitted for review prior to undertaking preparation of any data.

8.9 Calculations Calculations shall be provided to support the production of the signalling design.

8.10 Overlapping Design Agreement(s) (ODA) Where a drawing or drawings are required for a design and the drawing is already under the control of another design team then an ODA shall be produced in accordance with MTM document L2-SIG-PRO-007.

Failure to undertake and provide these mandatory requirements shall result in MTM rejecting the design until such time as they have been undertaken and provided.




9 Roles and Responsibilities of Contractors

9.1 General The contractors design office is fully responsible for their design, checking, verification and approval of their design.

The contractor shall validate the design through a rigorous testing procedure in accordance with the requirements of AS 4292.4 using independent and appropriately qualified, experienced and competent staff. The Contractor shall ensure that Signalling design and its installation are functionally in accordance with the approved scope and design specification(s). Tests shall then be carried out to validate that the installed system operates in accordance with the required signalling principles and safe working rules and regulations.

The contractor shall submit the Testing and Commissioning Plan to MTM for review and all comments shall be closed out in accordance with MTM’s Works Readiness Procedure (L1-NPD-PRO-002) unless agreed otherwise by the Office of the Chief Engineer.

9.2 Draftsperson The Draftsperson is the person who has drafted or has performed CAD work of the signalling drawing. The Draftsperson shall be identified by the initial of their first name and full last name (e.g. J CITIZEN) appearing in the drawing’s Title Block under “Drawn By” field.

9.3 Designer The Designer is the person who has designed the signalling drawing and shall be identified by the initial of their first name and full last name (e.g. B KING) appearing in the drawing’s Title Block under “Designed By” field. It is acceptable that the same person acts as draftsperson and designer.

9.4 Checker The Checker is the person who performs as the design office internal checker of the signalling drawing and shall be identified by the initials of their first name and full last name (e.g. M SMITH) appearing in the drawing’s Title Block under “Checked By” field.

9.5 Verifier The Verifier is the person who Independently verifies the signalling design and shall be identified by the initial of their first name and full last name (e.g. J BLOGGS) appearing in the drawing’s Title Block under “Ind Review” field.

9.6 Approver The Approver is the person who, within the production organisation, takes responsibility that the drawings have been appropriately checked & verified and who takes responsibility that the drawing has been through an engineering quality assurance process for its accuracy and safety in design. The Approver of the signalling drawing shall be identified by the initial of their first name and full last name (e.g. D JONES) appearing in the drawing’s Title Block under “Approved” field.




9.7 Certifier The Drawing Certifier is the person who, within the production organisation, takes responsibility that the drawings have been installed to as-built status.

10 Document Definitions The commencement of any technical review shall require the provision of the fundamental documents that identify the parameters by which the design is to be undertaken.

These include but are not limited to the following;

a) Final Operating Requirements

b) Signalling Functional Specification

c) Scope and Technical Requirements Specification

d) Design Management Plan

e) Drawing Management Plan

f) Master Drawing Register

g) Design Interface Management Plan

11 General Requirements of Contractors undertaking Design

11.1 Standards, Instructions and Type Approvals In order to maintain its status as an ARTO, MTM has to meet the requirements of its Safety Management System. This requires MTM to ensure that its Contractors conform to the relevant Standards.

11.2 Drawing Version Control The PTV Infrastructure Drafting Standards specify the version control requirements for drawings that are booked into the State drawing repository (Drawing Management System i.e. DMS) at the as-built stage.

The Design Contractor shall ensure their as built drawings comply with these requirements. Please refer to PTV Infrastructure Drafting Standards for current requirements.

The Contractor is responsible for maintaining its own document control system throughout the design lifecycle.

11.3 CBI Application Logic Data Structure (ALDS) Manual This document shall be produced by the design office and submitted for MTM review, with all comments closed, prior to any data preparation work being undertaken on the project.

The ALDS shall be produced, checked and independently verified in the same manner as all other designs submitted to MTM for review.

The purpose of this document is to clearly define all the rules and steps required to produce Interlocking data utilising standard data structures.




The data structures shall be clearly explained in detail in order for the reader to have a clear understanding of how the structures work and provide the functionality requirements of MTM as defined by the Victorian Rail Industry Operators Group Standards (VRIOGS) and/or any relevant MTM specific requirements (ie DPNs, RFIs, Chief Engineer’s Instructions etc.).

The ALDS shall include a typical signalling layout that the structures are based around in order to help the reader understand the structures application.

12 Design Modifications Once a design has been Issued For Construction (IFC) modifications to that design shall be approached in either of two ways, these being;

a) If construction has not commenced then the IFC design shall be modified, checked and verified, issued to MTM for review and once all comments closed issued as an up revised IFC design.

b) If construction has commenced then the design shall be modified, checked and verified, issued to MTM for review and, once all comments are closed, issued as a design modification on a design modification sheet.

Design modifications shall be produced in the same manner as any other design alteration and shall assume that any previous design alterations have been completed.

Design modifications shall be uniquely numbered and recorded in a design modification register.

13 Isolation and re-instatement of Signalling Equipment Project works requiring any signalling equipment isolated, false fed or removed shall require an isolation/re-instatement design package produced, checked, verified by the contractor and issued to MTM EDRG for review.
