1. Industrial training Electrical Loco Shed, Ghaziabad Abhishek Singh Roll No.1229040005

2. SYNTAX USED IN LOCOS Standard “Gauge” designations and dimensions:- W = Broad gauge (1.67 m) Y = Medium gauge ( 1 m) Z = Narrow gauge ( 0.762 m) N = Narrow gauge ( 0.610m) “ Type of Traction” designations:- D = Diesel-electric traction C = DC traction A = AC traction CA=Dual power AC/DC traction The “ type of load” or “Service” designations:- M= Mixed service P = Passenger G= Goods S = Shunting

3. . “ Horse power ” designations from June 2002 ( except WDP-1 & WDM-2 LOCOS ). ‘ 3 ’ For 3000 horsepower ‘ 4 ’ For 4000 horsepower ‘ 5 ’ For 5000 horsepower ‘ A ’ For extra 100 horsepower ‘ B’ For extra 200 horsepower and so on . Hence ‘WDM-3A’ indicates a broad gauge loco with diesel-electric traction. It is for mixed services and has 3100 horsepower .

4. I NTRODUCTION ESTABLISHMENT > Electric Loco Shed was set in 1976 by Railway Electrification Organisation ( 8910 SQ. MTRS). > It’s main purpose is of maintenance of WAP1,WAP4,WAP5,WAP7 , WAG5, WAM4 engines. INITIAL COST Rs. 1.5 (IN CRORES) PRESENT LOCO HOLDING 184

5. EMU CAR shed is an industrial-technical setup, where repair and maintenance works of EMU & MEMU is carried out, so as to keep the loco working properly. It contributes to increase the operational life of EMU & MEMU and tries to minimize the line failures. The shed consists of the infrastructure to berth, dismantle, repair and test the loco and subsystems . The shed working is heavily based on the manual methods of doing the maintenance job and very less automation processes are used in sheds, especially in India .

6. The EMU CAR shed usually has:- Berths and platforms for loco maintenance. Pits for under frame maintenance Heavy lift cranes and lifting jacks Fuel storage and lube oil storage, water treatment plant and testing labs etc. Sub-assembly overhauling and repairing sections Machine shop and welding facilities.

7. TYPES OF TRAINS IN EMU CAR SHED There are three trains are inspection and maintenance in EMU CAR shed. These are as follow :- 1. EMU 2. MEMU 3. DMU

8. EMU & MEMU

9. EMU – In EMUs one power car (motor coach) is required for three coaches so for an EMU has 12 coaches in length will have 4 power cars & mainly runs in the suburban sections of major cities. It considered as normal local trains such as life line locals of MUMBAI, HYDERABAD, CHENNI etc. 2. MEMU’s – In MEMUs one power car in needed for 4 coaches so MEMU are normally has 16-20 coaches long. It runs for long distance more than the suburban sections . It runs on the same line on which normal Local/ Exp /Mail/SF trains runs. MEMU – Vadodara – Ahmadabad MEMU MEMU were modified EMU’s introduced in 1993-94 3. DEMU’s – In DEMU’s , generally runs on diesel which tank capacity about >4000lts. It named as overhead electric inspection car used in repair & maintenance of overhead cables which fitted above the roof of trains carries 25kv A.C supply.

12. BOGIE

13. BOGIE’s A BOGIE is a wheeled wagon or trolley. In mechanics terms, a bogie is a frame work which carrying wheels attached to coaches. It is subassembly of 2 axle, 4 wheel, 4 brake cylinder , 2 side bearer, 4 bearing(double roller bearing), helical spring etc.

14. MEASURING & INSPECTION No GO NO gauge

15. TYRE DEFECT GUAGE Root wear Sharp flange Thin flange Deep flange Hollow tyre Flat tyre (tyre condum)

16. TRACTION MOTOR

17. TRACTION MOTOR

18. Traction motor refers to an  electric motor  providing the primary rotational torque to a machine, usually for conversion into  linear motion  ( traction ). Traction motors are used in electrically powered rail vehicles such as  electric multiple units  and  electric locomotives , other electric vehicles such as  electric milk floats ,  elevators , conveyors , and  trolleybuses , as well as vehicles with electrical transmission systems such as  diesel-electric , electric hybrid vehicles and battery electric vehicles

21. Pantograph

22. Pantograph M ounted on the roof of an electric  train. L ink between the overhead line and power circuit of electric locomotive . Sliding along a bare contact wire of the overhead system and conveyed to the roof line . 25 kv power electricity supply from overhead line to power circuit of electric locomotive . 4 to 6kg/cc2

23. Pantograph Dimension Length of pantograph – 2427+- 5mm. Height of insulater bottom of panto -205+- 5mm. Maxiam height – 2460+- 20mm Bow height - 300 Number of turn in main spring – 25/26 sliding angle of bow with wire – 71/2 Time taking 1.5m height to up – 6sec Time taking 1.5m height to down – 10sec

24. Application Use on 2kv AC electric locomotive . Suitable to use on 25kv AC electric multiple unit (EMU ). Suitable for satisfactory operation on electric locomotive up to 600hp to a speed 130km/hr . Rated current 400amp for AC . 1100amps for DC application.

25. MACHINE SHOP Different types of machines are used to maintain or reshape of the tool . Lathe machine Lathe pit machine Shaper machine Radial Drill machine Planner machine

26. P it Lathe machine

27. T ype of wear may occur on wheel Tread wear Root wear Skid wear Flange wear

28. For maintaining the required profile pit wheel lathe are used. This lathe is installed in the pit so that wheel turning is without disassembling the axle and lifting the loco and hence the name “ pit wheel lathe ” Gages are used in this section to check . Star gage Root wear gage Flange wear gage J gage

29. RADIAL DRILLING MACHINE

30. This drill machine to performing a hole in object with the twist drill. Use to produce hole heavier and bigger size job. This drill machine rotate in all 3 axis i.e. X-axis, Y-axis, Z-axis. Work pice remain remain stationary while tool rotates. Base made of heavy column .

31. High power-to weight ratio. Fewer Locomotive Fast Acceleration Higher limit of speed Higher hauling capability No carbon emission Less noise pollution Maintenance cost is 50% of that for steam engine. Steam engine requires two hours for heat up whereas electric engine start within moment. High torque motor are used in electric traction. ADVANTAGE OF ELECRICAL LOCO

32. Significant capital cost of electrification. Maintenance cost is high. Overhead wires further limit the clearance in tunnel. Railway traction need immune power, with no cuts. DISADVANTAGES
