    Study Notes

    Guidelines for Provision of Maintenance Depots, Tool and Plants and Transport Facilities

    • OHE maintenance depots should be optimized for minimum capital and recurring costs, considering factors like equipped track kilometers, traffic density, and proximity to yards.
    • Factors influencing depot location include: total equipped track kilometers, beat of the depot on either side, traffic density, time to reach farthest point, and proximity of major yards with substantial equipped track.
    • Availability of educational, medical, and other infrastructure in the area is also important.
    • The total staff for OHE maintenance is determined by existing maintenance standards and schedules, not the number of depots.
    • Each OHE depot should manage at least 150 track kilometers (250-300 EETKMs) to avoid unwieldy installations. This typically results in a spacing of 60 RKMs between successive depots on a double line section, reduced near major yards.
    • Depot beats should ideally not exceed four (occasionally five) blocks to ensure quick response to breakdowns.
    • Depot location should provide reasonable access to educational and medical facilities to retain staff.
    • OHE depot layouts have evolved, with major depots including tower wagons, sheds, and connections and a workshop, while minor depots are simpler.
    • Standard OHE maintenance depots should include basic tools like drilling machines and grinders.
    • A Divisional Repair Shop may supplement the OHE Depot, with specific layouts shown in figures.
    • Secondary activities like carpentry, welding, or smithy can be centralized at divisional headquarters or significant maintenance depots.

    PSI Maintenance Depots

    • PSI maintenance depots are for power supply equipment at substations, switching stations, and booster transformer stations.
    • Optimal location is alongside, or in conjunction with, OHE maintenance depots, for cost-efficiency.
    • Spacing between traction substations is typically 60-70 km, with closer spacing (40-45 km) in high-traffic areas.
    • PSI depots often handle maintenance for one or two substations and several switching stations.
    • A divisional repair shop could handle routine maintenance, if available, reducing the need for repeated transportation.
    • Equipment can be transported to the nearest substation for some major repairs where power supply is accessible.

    Scale of Transport and Plant (T&P)

    • Standard T&P items for OHE, PSI, and divisional repair shops are detailed in annexures. These may include tools, equipment, and furniture based on specific needs.

    Transport Facilities

    • Each major OHE depot has one heavy-duty truck and a 4-wheel inspection car for routine use and breakdown response.
    • Push trolleys, and jeep/trailers are provided for supervisors' inspection.
    • A wiring/breakdown train vehicle is needed to aid major OHE breakdowns.

    Additional Details

    • Figures and annexures (A6.01-A6.07) detail specific items for requisition for each depot type.
    • This information covers various tools, equipment, and furniture including specific types of vehicles used, and quantities needed.
