2 VRIOGS 010.7 Revision ASECTION 2.0DEFINITIONSTerminology used and / or applied in this Standard is defined as follows:TermAccredited RailOperator (ARO)ARTCBondingCWRCompetent PersonDesigner“Down” Track or“Down” DirectionElectrolysisElectrolysis Committeeof Victoria (ECV)Electrolysis ConnectionFlashoverIRJAccreditation VariationDescriptionA Rail Infrastructure Manager or Rolling Stock Operator whois accredited under Part 5 of the Rail Safety Act 2006.Australian Rail Track CorporationThe term used to define the connection and continuity ofpoints within a designed rail configuration/s; to ensurecontinuity of all designed rails for either track circuits toensure train detection is accomplished, or for the purpose oftraction return currents.Continuously Welded Rail.A person whose competency has been assessed by theARO or a recognised and accredited Authority as beingcompetent to perform the task.The legal entity undertaking the signalling design work in thisstandard.The direction or section of rail track that allows rail traffic totravel in a direction away from Flinders Street RailwayStation.Electrolysis is the leakage of stray Direct Current into theground, as an effect of the operation of both railway andtramway DC traction systems. This effect requires mitigationmeasures to prevent adverse effects and corrosion tosurrounding metallic infrastructure.The Electrolysis Committee of Victoria is the Industry Groupwho determines the actual locations of all necessary newelectrolysis connection points and also reviews all existingelectrolysis points and all electrolysis applications in Victoriawith the ARO.Connection used as a common point for Electrolysispurposes.An electrical discharge over the surface of an insulator.Insulated Rail Joint and may be either of a mechanicalconstructed type or a GIRJ.Change to the accredited activities (including operational ortechnical standards) of the Accredited Rail Operator andTram Operators requiring approval by the Director, PublicTransport Safety Victoria.NOTE: This document is controlled only when viewed on the DOT Engineering Standards website.Any other copy of this document is uncontrolled, and the content may not be current.

Touch potential is thevoltage you would be exposed to if you were standing on theground and touched the item.The area of a intersection where both tram and rail vehicleshave passage and where all rails within the actual squareare electrically bonded together and are then isolated fromeither side of the actual square by means of insulated railjoints.The person nominated by the ARO Infrastructure Manageras qualified and responsible for the installation andmaintenance of the traction current supply and distributioninfrastructure as its representative for the works in hand.The direction or section of rail track that allows rail traffic totravel in a direction towards the Flinders Street RailwayStation.The Victorian Rail Industry Operators’ Group comprising thefollowing members:• VicTrack• V/Line Passenger• Metro Trains Melbourne• Yarra Trams• Australian Rail Track Corporation (ARTC)• Public Transport Division of the Department of Transport(PTD)NOTE: This document is controlled only when viewed on the DOT Engineering Standards website.Any other copy of this document is uncontrolled, and the content may not be current.
