Study Notes

Chapter VII: Operation of EMUs

Duties of Motorman (30700): Motorman duties are consistent with loco operators (rules 30604, 30606, 30608-30616 and 30620), including maintaining EMU cab cleanliness.
Motorman's Personal Effects (30701): Motormen need specific tools (keys, controller, reverser, hand signals, flags – green/red, timetables, detonators (12), operating manuals, tools, journal books, etc.).
Motorman Taking Over Check (30702): A motorman must perform specific checks when taking over an EMU train, including pre-trip (after maintenance or long stands) inspections and confirming critical systems are functioning properly. (a) after maintenance, (b) at the start of the day or after lengthy stops.
Preliminary Checks (30703): Motormen should check the train's wiring, key availability, and defect registers.
Checks Before Starting Trains (30704): Essential checks before starting EMU trains include mechanical coupling, drain cocks, pneumatic/vacuum connections, proper cab locking, lights and marker systems. Ensuring fire extinguishers and alarm systems are ready
Auxiliary Warning System (AWS) (30707): An automatic warning system is in place to improve driver vigilance. This system cuts power automatically.
Joint Brake Testing (30708): Motormen and conductors perform a joint brake system test after maintenance.
Duties of Guards (30709): Guards participate in brake testing (30708), ensure lights/fans function well, and relay maintenance information.
Defects in EMU Trains (30710): Motormen are responsible for minor defect repairs. Major issues require notifying the relevant team.
Defects Noticed During Runs (30711): Problems affecting train operation (e.g., components or systems failing) should be reported promptly to the relevant authorities.
Turn-round Time at Terminal Stations (30712): A 6-minute minimum turnaround time is standard except in adjusted situations.
Stabling of EMU Trains (30713): Processes for safely storing EMU trains.
Coasting with Special Reference to EMU Operation (30714): Coasting is implemented to save energy and wear and tear. Coasting boards are used to indicate power cut-off points.
Operation with Traction Motor(s) Cut Out (30715): Specific procedures for certain circumstances (e.g. track maintenance).
Working of Trains when Tracks are Flooded (30716): Speed limits, special gauges and other safety procedures should be followed
Push Pull Operation (30717): Procedures for operating trains with the locomotive in centre, not at ends, with similar EMU operating procedures.
Long EMUs (30718): Procedure for operating long trains (8/9 cars) and their power supply requirements.

Additional Information

Dead Man's Handle (30706): A safety device. If the motorman loses control, the brakes apply automatically.
Automatic Brake Application (30705): A system for graded braking in emergencies.
