  • Function / Content
    This series consists of files relating to the design, maintenance and installation of overhead electrical wiring for permanent way train services, and the transmission of electric energy. From circa 1943 to 1983 this series was created by the Permanent Way Overhead Design Division of Victorian Railways (Electrical Engineering Branch). Administrative change throughout this period meant that the division was also known as the Overhead Superintendent's Office, Overhead and Electrolysis Design Division and Overhead Technical Division.

    From 1983 to 1989, following the abolition of Victorian Railways (VA 2876), the Overhead Design Division of the Metropolitan Transit Authority (MTA) inherited and continued to use this series. With the formation of the Public Transport Corporation (VA 2984) in 1989, the overhead design function was inherited by the Design Services Group of the Infrastructure Division.

    For the purposes of annual financial reporting the Electrical Engineering Branch was also known as Division 'G'. This identification system continued until 1964 when letter prefixes used for identifying Branches ceased.

    The series includes:
    - Overhead policy statements and policy files,
    - Meeting minutes, e.g., Site and construction meetings (in individual project files), Electrical Power Review committee, Stabling and Crew Coordination committee, Electrolysis committee,
    - Project files, estimates, specifications, photographs of works, and schedules including plans and circuit drawings for overhead lines,
    - Photographs, technical notes, reports and articles accumulated from overseas research trips,
    - Correspondence, and
    - Technical reports and manuals.

  • Recordkeeping System
    Files in the series were arranged under a two-number system. The primary number represented a broad administrative function, e.g., 300.00 General, 316.00 Insulators and Insulating Materials, 317.00 Switchboards and Control Devices, etc. The secondary number then divided the file into a more specific classification, eg 300.311 Corrosion, 300.12 Local Investigations, 316.15 Insulators up to 22,000 volts, etc.

    From 1983 this series was used concurrently with VPRS 12857 General Correspondence Files, Overhead Design, Double Number System. VPRS 12856 Index to General Correspondence Files, Overhead Design, Double and Single Number System indexed both of these series. A further series VPRS 12859, Subject Files, Overhead Design was also in operation between circa 1955 and 1993.

    It is likely that this system formed part of a larger recordkeeping system. The other components, including the general correspondence files for the Electrical Engineering Branch, (location is subject to further research). However, VPRS 12725 Register of General Correspondence, Electrical Engineering Branch and VPRS 12726 Index to Register of Correspondence, Electrical Engineering Branch should be consulted for summary details of the centralised general correspondence of the Electrical Engineering Branch.

    The date range of this series is subject to further research.

    Prior to the transfer of these records to PROV, the Public Transport Corporation had brought all filing systems pertaining to overhead design records together at their secondary record storage facility at Spotswood for retrieval and reference purposes.
