The rails are notdirectly earthed.Not all return negative current flows through the rails, as some current leaks off viathe rail fastenings, through the sleepers and ballast into the ground. In the ground itmay enter insulated pipes, cable sheaths and similar underground metallic structuresand flows towards the substation. At some point that current leaves the undergroundstructures and returns to the rails and back to the substation negative bus bar.Corrosion is likely to occur where the current leaves the underground structures toreturn to rail.The loss from pipes and cable sheaths is confined to small areas which quicklybecome perforated to the detriment of the pipe or cable.Tests shall be conducted by the Departments Representative on the in-servicesubstation to determine the active electrolysis conditions and whether there is a needfor Electrolysis Mitigation Equipment.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.

It refers consistently to the design drawings and isused to amplify points about the design drawings.The documentation is to be read and able to be understood by the constructionworkforce.11.2.2 SYSTEM RECORDSIn order to facilitate operation and ongoing maintenance of the traction power supplylocation, the designer shall provide maintenance documentation for electricalequipment not already existing within the Department's traction system. Thisdocumentation shall include drawings, schedules and special requirementsnecessary to maintain the equipment for its estimated life and will be included intothe MAINCO Technical Maintenance Plan (TMP). Refer appendix A of this standardfor the format to use for a Technical Maintenance Plan.11.3 FINAL DESIGN AND DOCUMENTATION11.3.1The final design at this stage allows the full construction of a substation. The finaldesign and documentation requires the completion of all designs, drawings,specifications, schedules and documentation pertinent to proprietary items fullydetailed to enable the Department to invite public tenders for the construction works.11.3.2The final design and specifications shall comprise:• Scale plans and detailed drawings showing the works described in theseDesign Standards in sufficient detail to permit construction.• Works Instructions that are required to describe the work, materials anddrawings required to permit construction. The work instruction shalldescribe information such as tools to use, other ancillary equipment thatwill be required to carry out the work, installation instructions andprocedures etc. The work instructions shall be of sufficient detail toenable a construction contractor to carry out the work without requiringadditional clarifications.• Works Instructions for the manufacture and supply of major items ofmaterial or prefabricated structures.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.

VRIOGS 010.3 Revision A 3711.3.3The designer shall provide to the Department or its representatives, full sets of thedetailed drawings, specifications, material schedules and documentation for review,comment and approval.11.3.4Upon completion, the designer shall provide to the Department or its representatives,the original of all final drawings and a master copy of all the specifications, schedulesand any other documentation. The designer shall also provide copies of the aboveinformation on a CD in “PDF” and "Microsoft Office Word - Version 11.8" format fordocuments and in “PDF” and "Intergraph" microstation ‘dgn' format for all drawings.The drawings shall also be submitted to the VicTrack Drawing Management System(DMS).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.

38 VRIOGS 010.3 Revision ASECTION 12.0 REVIEW AND APPROVAL PROCESS INDESIGNThe Department requires that all designs of the rail traction power supply assetsmeet the objectives of functionality and minimum "Whole of Life" costs whilemaintaining the highest standards of personnel and general public safety.A further consideration is the need to take advantage of "best world practice" in railtraction power supply technology while maintaining system, operational andmaintenance compatibility with the existing traction power supply infrastructure of theDepartment.To that effect, the overall review and approval process is described in the “VRIOG –Design, Construction and Handover Process” document.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.
