As part of the approval process, the Standing Committee verified that proper process was followed in developing the Standard. RISSB wishes to acknowledge the positive contribution of subject matter experts in the development of this Standard. Their efforts ranged from membership of the Development Group through toPrinciples individuals providing comment on a draft of the Standard during the open review. I commend this Standard to the Australasian rail industry as it represents industry good practice and has been developed through a rigorous process. Comment Paul Daly Chief Executive Officer Rail Industry Safety and Standards BoardSignalling Public Keeping Standards up-to-date Australian Standards developed by RISSBfor are living documents that reflect progress in science, technology and systems. To maintain7711 their currency, Australian Standards developed by RISSB are periodically reviewed, and new editions published when required. Between editions, amendments may be issued. Australian Standards developed by RISSB may also be withdrawn. It is important that readers assure themselves they are using a current Australian Standard developed by RISSB, which should include any amendments that may have been issued since the Standard was published.

Major modifications to signalling systems shall consider the principles of this Standard so far as is reasonably practicable. These signalling principles support the safe application of a Rail Transport Operator’s (RTO) signalling-based safeworking system, promote a consistent application of signalling principles throughout Australasia and should– (a) detail the underlying principles of signalling system design; (b) be independent of specific RTO’s requirements; (c) be independent of technology used; and (d) identify the risks (hazards) being controlled. Principles 1.2 Scope This Standard provides details on underlying signalling principles commonly used to control rolling stock operational risk. It does not preclude the application of higher performance standards (e.g. based on local experience and good engineeringComment practice which may be contained in the management of Standards, Codes, Guidelines and procedures of individual Australia States or RTOs). This Standard covers the engineering controls for signalled movement authorities. It does not cover procedural controls in yard working areas. 1.3 Exclusions Signalling This Standard is not specifically intended toPublic cover urban on-street tramway or light rail networks, cane railways, or heritage railways operating on private reservation, but items from this Standard may be applied to such systems as deemed appropriate by the relevant RTO.
