  4. -: CoachRepair Workshop, Harnaut:- • Foundation stone was laid by A.P.J. Abdul KalamonJune 30, 2003 • Site location -Harnaut, Distt- Nalanda (Bihar) ,under ECR • Total Land       - 113 Acres(workshop 76 , staff quarters 37) • Year of sanction-2003-04Sanctioned Cost-Rs. 224 Cores.Revised sanctioned Cost-Rs. 337 Cores.Expenditure-Rs 252.03 Cores. (up to 31.03.13 )Plant Capacity- POHof50 coaches per monthSanctioned staff - 1158

  5. -: THE MAINTENANCE SCHEDULES AND THEOVERHAULING PERIODS :- 1. Trip schedule- After every trip by primary maintenance depot. 2. Schedule A - Monthly (1 month ) 3. Schedule B - Quarterly (3 months ) 4. IOH – 9 months 5. POH – 18 months > POH < Periodic overhauling is the best available process of maintenance of coaches in India. This generally operated after 18 months after the manufacturing or the previous periodic overhauling done in any workshop. This undergoes a huge process of lifting the coach, isolating the all parts, and changing or replacing the necessary or damaged parts. In other words this is the process of renewing the coaches. • -It stands for periodic overhauling. • -POH is allowed in nominated workshops only. • -Painting of whole coach is necessary. • -Profiling of wheel is necessary

  6. -: WHEEL PROFILE :- -: DEFECTS :-

  7. Tyre defect gauge THIN FLANGE SHARP FLANGE HOLLOW TYRE THIN TYRE

  8. Integral coach factory Linke Holfmann Busch 160 km/h 140 km/h Noise level 60 decibels Noise level 100 decibels DIMENSIONS OF COACH SHELL ICF LHB Length With Buffer 22296 mm 24000 mm Length Without Buffer 21336 mm 23540 mm Width 3245 mm 3030 mm Life 25 Years 30 Years

  9. -: AXLE :- DISC

  10. -: AIR BRAKE SYSTEM :- • The brake system in which compressed air is used in the brake cylinder for the application of brakes is called air brake system. MAIN COMPONENTS :- Control Reservoir 9 liter, 5 kg/cm2 Auxiliary Reservoir 200 liter, 6 kg/cm2 Brake pipe – Dia. 32 mm Feed Pipe – Dia. 25 mm

  11. -:Working Principle:- The different processes involved in working :- a) Charging b) Application c) Release • Under normal conditions the Brake pipe is charged with 5kg/cm2 from the loco. The control reservoir and the Auxiliary reservoir are charged with 5 kg/cm2 and 6 kg/cm2 respectively from BP through Distributor valve. • When the brake pipe is charged at 5 kg/cm2 the brake cylinder is connected to exhaust through distributor valve in order to keep the brake in released position fully. • Whenever the brake pipe pressure is reduced below the CR pressure, the DV connects the auxiliary reservoir with the brake cylinder and the air from AR is sent into the brake cylinder to apply the brake. • Whenever the brake pipe pressure is equal to CR pressure the DV disconnects the BC from AR and in turn connects the BC with Exhaust for the release of brakes fully.

  12. -: BRAKE SHOE :- SHOES

  13. -: BOGIE FRAME :- 1.Bogie frame longitudinal component 2. Cross-beam • The frame is made up of two longitudinal components (1) connected by two cross-beams (2) which also support the brake units. The various supports which connect the different bogie components are welded to the frame.

  14. -: BODY SHELL :-

  15. -: WINDOW UNITS :- • The sealed window units consist of 8.4 mm outer glass and 4 mm inner glass with 6 mm Argon gas filled. • Argon is an inexpensive, non-toxic, odorless gas . • It increase sound proofing characteristics of the window. • Minimizes heat exchange through the window. • Argon will not corrode the window material. • This type of windows can even block ultraviolet rays.

  16. -: Controlled Discharge Toilet System (CDTS) :- -: Working cycle : -  On each flushing (Collection):- Simply pressing flush button, starts the flow of water into the toilet bowl and opens the flapper valve connecting the toilet bowl to the waste retention tank. At the end of each flush cycle the wash water stops and the toilet is sealed off from the retention tank by the flapper valve, which acts as an effective stench trap, preventing odor from entering in the toilet room.  The retention tank discharge valve remains open only for a small period of time (one minute or less) long enough to completely drain the retention tank, then closes and remains closed until the required parameters are again satisfied.

  17. The waste is stored in the retention tank until the following two parameter are satisfied. Programmable Logic Controller (PLC):- It is the heart of the system. It senses the speed of the coach and no of flushes and gets all the operations done by actuating corresponding valves. .

  18. -:WATER TANKS :- 3 types of water tanks are provided in LHB coach
