    Study Notes

    Operation of Locomotives

    • Trailing loads assigned to locomotives are governed by RDSO load charts (Annexure 1.03).
    • Loads are calculated considering theoretical site conditions and track geometry.
    • Actual site conditions and track geometry may differ.
    • Partial brake binding, driver capabilities, and weather can affect the actual load hauled.
    • Trials with actual sections and loads should be conducted to verify locomotive capabilities on specific sections.
    • Multiple locomotive operations require separate trials for different numbers of locomotives (2, 3, or 4).
    • Load distribution between locomotives may not be equal due to manufacturing tolerances and varying wheel diameters.
    • Nominated loads (single and multiple) for each section and loco class should be determined and tabulated.
    • Loads for each section and locomotive class should be determined by CEE in consultation with COM.
    • Loco link diagrams are prepared to maximize locomotive utilization by minimizing downtime at terminals.
    • Close coordination between senior DOM/DOM and senior DEE(OP)/DEE(OP) is necessary.

    Assessment of Operating Staff for Electric Locos

    • Running staff requirements are determined based on timetables and minimum rest periods.
    • Staff requirements for Rajdhani/Shatabdi and other high-speed trains are adjusted due to co-driver responsibilities.
    • Assessment considers the "turn-round" method, encompassing "signing-on time" and "signing-off time" plus waiting duty.
    • Average driver turn-around time includes journey time.

    Duties of Electric Loco Drivers

    • Drivers must inspect the locomotive logs and inspect for abnormalities.
    • Drivers must pay close attention to overhead lines.
    • While examining the undercarriage, maintain brakes in the "ON" position.
    • No unauthorized personnel are allowed in the cab (except authorized supervisors or staff by written order).
    • Drivers are responsible for locomotive cleanliness.
    • Special checks are required if the halt duration exceeds 10 minutes.
    • Report any abnormalities during operations and submit reports.

    Knowledge of Road

    • Drivers and assistants need thorough knowledge of assigned sections (maximum speeds, gradients, land marks, signals, etc.).
    • If drivers are absent for six months, read the road again (or the time period may be adjusted by local instructions).
    • Road Knowledge Registers (separate for each section, each staff category) are maintained, following a specific format.

    Driver's Personal Equipment

    • Drivers are expected to have specific tools (log book, operating manual, rules book, watch, wrenches, torch, flags etc.)

    Personal Effects of Assistant Driver

    • Assistant drivers are expected to have specific tools (flags, journals, watches, etc.).

    Operation of Air Braked Stock

    • Operation details for Air Braked stocks
    • Procedures for checking leakage rate of the air brake system, with and without auxiliaries.
    • Instructions on operating and maintaining air-braked stock.

    Master Controller

    • Master controller operation (stable/unstable positions) for traction and braking is explained.

    Starting of a Train

    • Two-stage initial starting and acceleration is outlined, for both down and up gradients.

    Speed Control

    • Speed regulation when current falls below rated values; including field weakening.

    Neutral Sections

    • Crucial information on switching off power when passing through neutral sections are provided, including specific signage.

    Double Heading

    • Procedures for operating trains with two locomotives.
    • Maximum speed limitations for double headed operation.

    Heavy Haul Trains

    • Procedures and instructions for operating trains classified as Heavy Haul.
