T HR SC 00004 ST Signalling Design Requirements – Signalling Symbols
Version 1.0 Issued date: 11 March 2016
Preface The Asset Standards Authority (ASA) is an independent unit within Transport for NSW (TfNSW)
and is the network design and standards authority for defined NSW transport assets.
The ASA is responsible for developing engineering governance frameworks to support industry
delivery in the assurance of design, safety, integrity, construction, and commissioning of
transport assets for the whole asset life cycle. In order to achieve this, the ASA effectively
discharges obligations as the authority for various technical, process, and planning matters
across the asset life cycle.
The ASA collaborates with industry using stakeholder engagement activities to assist in
achieving its mission. These activities help align the ASA to broader government expectations
of making it clearer, simpler, and more attractive to do business within the NSW transport
industry, allowing the supply chain to deliver safe, efficient, and competent transport services.
The ASA develops, maintains, controls, and publishes a suite of standards and other
documentation for transport assets of TfNSW. Further, the ASA ensures that these standards
are performance-based to create opportunities for innovation and improve access to a broader
competitive supply chain.
T HR SC 00004 ST Signalling Design Requirements – Signalling Symbols provides the
standard (typical) signalling symbols that are used throughout the life cycle of a signalling
project or asset.
This standard has been developed by the ASA and approved by the ASA configuration control
board.
This standard is a first issue.

• SPG 0703 Signalling Documentation and Drawings
• TMGG 1550 Signalling Documentation Guidelines
• TMGA 1510 Signalling Design Process for Projects Managed by Third Parties

T HR SC 00004 ST Signalling Design Requirements – Signalling Symbols
Version 1.0 Issued date: 11 March 2016
1. Introduction The ASA owns and maintains the standard signalling symbols that are used on various
signalling documentation, such as signalling plans, driver's diagrams, track insulation, air
system plans and circuit books.
2. Purpose The purpose of this document is to provide the standard symbols that are used as a basis to
perform signalling design on the Sydney metropolitan rail area. This standard aims to provide
consistency in applying the standard signalling symbols across the TfNSW heavy rail network
and for all organisations involved throughout the life cycle of the asset.
2.1. Scope For new and retrofit installations, this document can be used as a standard template for the
production, review and verification of specific signalling designs, for a particular asset or
system.
Signals are built up of various elements such as signal heads, subsidiary light units and route
indicators to suit the situation; not every possible configuration is shown in this standard.
2.2. Application This standard applies to various signalling equipment, infrastructure types and configurations to
suit the current assets in use and for new installations.
This standard applies to AEOs and competent personnel engaged in the provision of services
relating to rail signalling infrastructure across the whole asset life cycle.
This standard applies to the signalling systems within the Sydney metropolitan rail area.
3. Reference documents The following documents are cited in the text. For dated references, only the cited edition
applies. For undated references, the latest edition of the referenced document applies.

5. Configuration Signalling infrastructure can be built of a variety of components. The key elements are
presented in this document to permit an appropriate signalling item to be constructed.
The symbols are drawn and placed on signalling documentation, including the CAD levels. The
CAD levels are specified in T MU MD 00006 ST Engineering Drawings and CAD Requirements.
Care shall be taken during the production of symbols to ensure that correct representation, line
widths and proportions are maintained. Signalling documentation is used for certification and
equipment profiles, and the details should be accurately portrayed. Symbols shall not be
mirrored or their configuration modified. Most symbols bare a relationship to installed
equipment.
Where there is a need for any symbols to be created or existing symbols to be modified,
permission shall be sought from the Lead Signals and Control Systems Engineer, ASA. © State of NSW through Transport for NSW Page 7 of 38

6. SymbolsCompliance with the requirements in this standard will not, by itself, be sufficient to ensure that
satisfactory outcomes will be produced. Personnel providing services based on the standard
need to bring appropriate expertise to the matters under consideration.
Application of the signalling symbols shall be in conjunction with the following documents:
• T HR SC 00001 ST Circuit Design Standard – Typical Circuits – developing signalling
circuit book design using typical circuits
• TMGG 1550 Signalling Documentation Guidelines – presenting signalling circuits and
equipment in signalling documentation
• SPG 0703 Signalling Documentation and Drawings – design presentation, content and
submission
• ESG 100 Signal Design Principles – fundamental requirements of signalling system and its
assets
Section 6.1 through to Section 6.5 provides standard signalling symbols used on a variety of
signalling documentation.
6.1. Signalling plan symbols Section 6.1.1 through to Section 6.1.12 provides standard signalling symbols associated with
signalling arrangements used on signalling plans.
