Study Notes
Knowledge of Rules and Breakdowns
- All officers and supervisors in the Traction Branch must be familiar with accident reporting rules and other relevant instructions.
- Supplementary instructions for traction installations are provided, but do not override general official manuals.
- Electrical accidents are covered in Volume I.
Types of Breakdowns
- Breakdowns are categorized into sub-station and switching stations, remote control equipment and cables, and OHE feeder lines and transmission lines.
Breakdown Gangs
- Maintenance gangs typically handle accidents and breakdowns.
- Experienced traction staff, stationed near installations, are crucial for quick response to breakdowns and accidents.
- Breakdown gangs of appropriate strength are located at points in electric suburban sections to quickly respond to OHE failures, especially at peak traffic times.
Emergency Stores and Breakdown Equipment
- Each OHE depot/sub-depot should have a specific quantity of spare parts (masts, conductors, insulators, etc.) for breakdowns.
- Initial inventory should cover 3 kilometers of single line.
- Quantities can be adjusted based on experience.
- OHE stores inventory should be regularly maintained and inspected.
- Equipment such as inspection cars, wiring trains, breakdown lorries, and tools (clamps, ladders, etc.) must be in good working order.
Record of Staff Emergency Staff
- A register of staff addresses (particularly those in railway quarters or near stations) is needed to quickly contact staff.
- Phone numbers of officers and supervisors are also to be kept up to date.
- Telephone equipment should be checked monthly for functionality.
Sub-Station and Switching Station Breakdowns
- Traction transformer breakdowns are infrequent at sub-stations because of total redundancy (100% backup).
- Repair and overhaul facilities for transformers should be available at central railway repair shops.
- Crane bays, oil storage tanks, a purification plant, a workshop for repairs, and oil-testing equipment are essential at the repair shops.
Mobile Power Van
- Each railway with traction transformers should have a mobile power van.
- A generator is required, as well as capacity for oil purification and a small mobile workshop.
- This allows on-site repairs of traction transformers, eliminating the need to bring them to a central repair shop.
Breakdown of Remote Control Equipment
- Remote control operations should be suspended if the P&T cable or equipment fails.
- Qualified staff is needed for manual switching operations under such circumstances.
- A list of authorized operators is to be kept up to date for this purpose.
Restoration of Remote Control
- Remote control should be restored as quickly as possible.
- Alternative communication channels (telephone, local lines, wireless, microwaves) should be available if the primary line fails.
- Coordination between departments (Traction Distribution, S&T, and DOT) is essential for quick restoration.
OHE Breakdowns
- OHE breakdowns like uprooting of masts, entanglement of pantographs, snapping of conductors, are common incidents.
- Engine crews need to report any detected OHE defects.
- Immediate measures to restore traffic should be taken.
- Staff must implement safety precautions for themselves and others.
Protective Steps
- Section controllers should regulate traffic and issue relevant cautions related to affected lines after the receipt of OHE breakdown notifications.
- Single-line operation may be implemented.
- Ensure no one comes into contact with live suspended OHE parts.
Continuous communication with TPC
- Field staff needs to remain on call for maintenance.
- Thorough assessment of breakdowns by initial staff arriving is critical.
- Request additional gangs and equipment if required.
Preservation of Evidence
- Note relevant details of OHE breakdowns, and create sketches
- Preserve evidence for potential causes investigation.
Temporary Repairs
- In critical cases, restoring traffic with minimum repairs is priority.
- Staff safety should be ensured and traffic restrictions implemented.
- If necessary, switch to diesel/steam traction for periods of OHE repair
- Utilize special equipment like wiring trains where extensive damage is present to speed up repairs.
Temporary Diversions
- Temporary wiring diversions might be needed due to track disruptions or incidents.
