Study Notes
Infrastructure Facilities for Freight Yards, Sick Lines, and ROH Depots
- Introduction: Proper maintenance of freight stock is crucial for optimal performance. Infrastructure availability directly impacts maintenance effectiveness.
-
Examination/Repair Facility Categorization (Intensive Examination Points):
- Category A: Pucca pathways on more than 50% of designated lines, 150 lux illumination, sufficient material handling and welding facilities.
- Category B: Similar to A, with adequate illumination, material handling, and welding facilities, impacting more than 50% of lines.
- Category C: Pucca pathways on over 50% of nominated lines; sufficient illumination and material handling are present.
- Category D: Pucca pathways are not present but other facilities are available.
- Category E: No facilities available.
-
ROH Depots Criteria:
- Category A: All infrastructural facilities are sufficient.
- Category B: Essential facilities are available, but some may not meet target output requirements.
- Category C: All but some vital facilities (like EOT crane/wheel turning lathe) are adequate.
- Category D: Facilities are inadequate or nonexistent.
-
Sicklines:
- Criteria: Berthing capacity (covered shed), heavy-duty concrete flooring, availability of welding, compressor/exhauster facilities. Categories are similar to the standards for intensive examination points.
-
Infrastructure & Facilities Required in the Yard:
- Minimum center-to-center distance between tracks is 7.5 meters.
- Concrete pathways for smooth material and personnel movement.
- Proper lighting for wagon inspection.
- Welding grids for efficient wagon repairs.
- Outlets for air pressure testing.
- Duty rooms, staff rooms, storerooms, etc., with essential equipment and machinery (compressors, welding machines, etc.).
- Communication systems (VHF sets, CUG phones) for proper coordination.
- Inspection lamps (portable LED).
- Machinery & Plant Items: Essential for examination: Diesel & electric compressors, welders, wagon/rake test rigs.
Infrastructural Facilities for Freight Examination Yard (IF PROPOSED)
- Yard Design: Includes examination lines (750m each) for keeping sick and fit wagons, complete with abrasion-resistant flooring and ballast-free track construction, and 7.5m center-to-center distances.
-
Examination Line Enhancements:
- Dedicated lines with proper layout for handling rakes.
- Additional crane and vehicle support facilities.
- Sufficient wiring for equipment and staff safety.
-
Overall Yard Improvement:
- A major focus on repair and maintenance facilities.
- Comprehensive contracts for yard upkeep to manage scrap and minor maintenance work.
- EOT Crane Capacity & Maintenance: Includes EOT cranes (30-tonne capacity), slings (for lifting wagons), material handling vehicles.
- Yard Accessibility Enhancements: Multi-utility vehicles for material transport. Covered shed with alternate light sources.
- Comprehensive Contracts: For major maintenance tasks and upkeep of yard facilities (e.g. sheds, floors). This includes M&P (major machinery and plant) maintenance of EOT cranes, compressors, welding, hydraulic jacks.
Infrastructural Facilities in Air Brake ROH Depots
- Depot Categorization: Super, Mega, Major, and Minor Depots are categorized based on targeted monthly ROH output capacity.
- Layout Recommendation (for 250 ROHs/month): This includes a focus on berthing capacity for ROH wagons, handling capacity, and layout of bogie (repair) and body repair sections.
Minimum Infrastructure for Premium & CC Examinations
- Dedicated Examination Lines: Two or more examination lines with pathways are essential for quick, efficient processing.
- Paths/Walkways: Paved walkways (2 meters wide) are critical for easy movement within the examination area.
- Welding Facilities: Portable welding sets with adequate illumination and power are necessary.
Facilities Required in Freight Examination Yards
- Examination Lines: Dedicated lines for premium/CC examination, accommodating the number of rakes under examination.
- Pathways: Well-maintained paths and walkways for personnel and equipment movement.
- Illumination: High masts/tower lights for general illumination, lamp posts along pathways for specific tasks.
- Welding Transformer Room: For welding work.
- Air Compressor: Maintaining suitable capacity is crucial.
- Tooling/Sub-storerooms: Proper storage and maintenance areas for all materials required in the maintenance work.
Facilities Required for Maintenance of Stainless Steel Wagons
- Welding Equipment: MIG/MAG and DC Arc welding sets of specific capacities for different tasks.
- Cutting Equipment: Portable air plasma cutting machines.
- Consumables: Various welding electrodes for different types of steel, along with other materials.
- Lock Bolts/Equipment: For securement and maintenance.
- Grinding/Polishing Machines: Tools for grinding/polishing/cleaning required materials and surfaces.
