Study Notes

Yard Maintenance

Yard maintenance is crucial for efficient freight stock operation
Factors affecting good and quality examinations/repairs include yard maintenance standards
Examination methods are described in subsequent paragraphs

Notification of Examination Points

Railways notify nodal examination points authorized to issue brake power certificates
These nodal points must have facilities such as paved pathways, welding points, lighting, etc., for air brake train examination
Brake Power Certificates (BPC) are issued only from these nodal points

Pattern of Freight Train Examination

End-to-End Examination:
- Empty rakes are typically examined intensely, except during back loading at stations or sidings
- After intensive examination, the rake is moved to the loading station as per traffic requirements
- Empty rake's BPC might not have a destination, but after loading, operating staff (or commercial staff) indicate the destination on the BPC
- No loco pilot can move a loaded train without a clear destination on the BPC
- After unloading, the rake is re-examined in empty condition
Premium Examination:
- Premium rakes have a 12-day validity BPC with a 3-day grace period for examination in empty condition
- Specific conditions are needed to be met for the rake to be certified as premium. This includes examination in an empty condition and examination at nominated examination points.
- BPCs for premium rakes are valid for 12 days from the date of issue
- For these rakes multiple loading/unloading are allowed
Close Circuit Examination:
- Ideally, close circuit air brake rakes should be formed from off-ROH and off-POH wagons
- Thorough maintenance history (bogie, draft gear, coupler, AB system, wheel, & CTRB) is maintained by the Base Depot
- Originating brake power for air braked goods trains should be 100% with sufficient brake block thickness
- Base depot should record details regarding enroute detachments, brake power and detachments during examination
- Each BPC of a CC rake is valid for 6000/7500 kms or 30 days (whichever is earlier)
- The kilometrage must be accurately recorded

Post Loading and Post Tipping Examination

After tippling, the rake is checked by TXR staff or Guard and Loco pilot (if TXR staff isn't available)
Post-tippling inspections vary based on local conditions
Guard and driver checks should be done based on established formats

GDR Check

A GDR check is necessary for post loading/back loading of a rake
After tippling, a post-tippling check may be performed by Guard & Loco pilot

Examination Details

Rolling-in/Terminating examination is conducted on trains entering the yard
Intensive examination includes repairs, detachment of damaged wagons, and brake testing, done on originating trains
Brake continuity of the formed load is confirmed

Freight Train Examination and Repairs

Inspect running gear fittings, brake gear and spring gears, draw and buffing gear.
Repair any deficiencies in safety fittings, brackets, and loops
Replace worn brake blocks
Correct fitment of washers, cotters, and pins
Ensuring correct functioning of empty load devices
Inspection of covered wagon doors.

Air Brake Testing

Testing of single pipe and twin pipe air brake rakes are performed using dedicated test rigs.
Important considerations include establishing stable pressure, monitoring pressure drop, checking for leaks, and inspecting components like distributor valves, cylinders
Important parameters like pressure drop is carefully monitored.

Service Application and Release Test

The driver's automatic brake valve is moved toward service application
Brake blocks are checked for proper application.
Piston strokes of each wagon are checked

Examination of Container Trains (BLC/BLL Rakes)

Examination points are developed, including infrastructural facilities
BLC/BLL rakes are examined in empty condition (without containers)
Every Close Circuit (CC) rake must be thoroughly examined at its base depot, and a fresh BPC issued, valid for 6000 km or 30 days (whichever comes first)
On completion of the stipulated distance/time, CC rakes must be returned to the base depot

BPC Formats

Format I is for end-to-end examined goods rakes
Format II is for premium rakes
Format III is for close-circuit rakes
Information like train number, loco number, brake power, and pressure values is recorded in each format
