Study Notes

General Breakdowns

All traction branch officers and supervisors must be familiar with accident reporting rules and instructions for breakdowns.
Supplementary instructions are provided for traction installations, not contradicting other official manuals.
Electrical accidents are covered in a separate volume.

Types of Breakdowns

Breakdowns are categorized into sub-stations, switching stations, remote control equipment and cables, and overhead electric lines (OHE) feeder/transmission lines.
Breakdown gangs of experienced traction staff should handle accidents/breakdowns at traction installations.
Electrified suburban sections require dedicated breakdown gangs during peak traffic hours.

Emergency Stores and Equipment

Each OHE depot/sub-depot should have a specific quantity of OHE stores (masts, conductors, insulators, fittings, etc.) for breakdowns.
The minimum and maximum OHE store quantities are estimated based on experience and revised periodically.
OHE inspection cars, wiring trains, breakdown lorries, and tools (straining screws, clamps, ladders) must be maintained for use.
Supervisors and officers should regularly inspect breakdown equipment adequacy.

Sub-Station and Switching Station Breakdowns

Breakdowns of a single traction transformer or circuit breaker at a sub-station should not halt operations due to backup availability.
Central repair shops are needed for major traction transformer repairs.
These facilities should include a crane bay, oil storage tanks, oil purification plant, testing equipment, and a small workshop for urgent repairs.
A mobile power van for maintenance of traction transformers is necessary.

Breakdown of Remote Control Equipment

Remote control operations are suspended when issues arise with P&T cables, remote control equipment, or batteries.
Qualified staff ("Operators") should manually operate switching stations while issues are addressed.
A register of trained and approved operators is maintained.
Operators must familiarize themselves with equipment workings and administrative procedures.
Operators maintain a log of operations, interruptions of supply, malfunctions, and other relevant records.
Other personnel (e.g., Khalasi) should accompany operators, especially if they need telephone support.

OHE Breakdowns

Minor OHE breakdowns must be addressed expeditiously to reduce traffic disruptions.
Common OHE breakdowns include mast uprooting, pantograph entanglements, conductor snapping, and insulator faults.
OHE restoration work should be performed as quickly as possible.

Records and Reporting

Continuous records of staff movements are essential for quick responses to emergencies.
Detailed reports on OHE breakdowns should be submitted to relevant authorities (with sketches, timelines, costs, and staff details).
A detailed log of events is critical for assessing responsibility and improving future response times.

Protection of Staff

Work on OHE should only start after the power block is obtained and staff protection measures are in place.
Visual signals (GR and SR) are used during repairs.
Special care is required when using cranes to avoid contacting live OHE components.

Road Vehicles

Road vehicles such as trucks and jeeps should be maintained, authorized drivers need to have the necessary permits, and vehicles should be kept safe for use during emergency situations.

Maintenance of Road Vehicles

Road vehicles should be inspected for defects, and any damage should be addressed immediately.
Emergency vehicles need specialized maintenance and inspections to ensure readiness.
Suitable staff training is required to ensure that those operating road vehicles are competent.

Log of Events and Reporting of Breakdowns

Detailed logs recording events, repair durations, and costs are essential for assessing efficiency and identifying issues.
Staff should report any OHE defects to the relevant authorities immediately.

Funds Required for Dealing with Breakdown

Stations can use funds available from station earnings to aid in dealing with accidents and breakdowns.
Appropriate authorization and documentation are required when using station funds.
