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.
This standard supersedes RailCorp standard EP 08 00 00 16 SP Designations of Overhead
Wiring Conductor Systems, version 2.1.
The changes to previous content include the following:
• updates to reflect organisational changes and resulting changes in responsibilities
• minor amendments and clarification to content
• conversion of the standard to ASA numbering, format, and style

Version 1.0 Issued Date: 08 July 2015
1. Introduction Overhead wiring (OHW) is used to transmit power from traction substations to electric trains.
OHW generally consists of catenary and contact wires. The contact wire provides a
mechanically continuous path for train pantographs, and the catenary wire is used to support
the contact wire. The traction current to the trains is carried by both the catenary and contact
wires.
2. Purpose The purpose of this document is to list all overhead wiring conductor systems that have been
used in the RailCorp network and to provide a consistent shorthand designation for each
conductor configuration.
2.1. Scope The scope of this document is for 1500 V dc overhead wiring conductor systems as used in the
RailCorp network.
For new installations, all conductors shall be in accordance with T HR EL 08004 ST Overhead
Wiring Fittings and Materials. Contact wires shall also comply with EP 08 00 00 24 SP Contact
Wire.
For information on the process of selecting a suitable OHW system, refer to EP 08 00 00 17 SP
Overhead Wiring Conductor System Selection.
2.2. Application This document provides a detailed description of each overhead wiring conductor system that
has been assigned a Technical Maintenance Code (TMC).
This document is not to be used as a reference for the actual overhead wiring conductor system
installed at a particular location.

5. Status of overhead wiring conductor systems Each overhead wiring conductor system listed in this document is assigned one of the following
status categories:
• current - an OHW conductor system approved for use for the electrification of new routes,
and for the major rehabilitation of existing infrastructure. See EP 08 00 00 01 SP.
• Not for Future Construction (NFC) – the OHW conductor system may remain in service
where already installed. This configuration shall not be used for future construction. When
approved via a concession, the configuration may be used for extensions and alterations to
equipment of the same configuration.
• obsolete – OHW of this configuration shall not to be used for future construction. Any
existing OHW should be programmed for renewal.
