4. INTRODUCTION
 Indian Railways has one of the largest and
busiest rail networks in the world, transporting
over 18 million passengers and more than 2
million tones of freight daily. It is the world's
largest commercial or utility employer, with
more than 1.4 million employees. The railways
traverse the length and breadth of the country,
covering 6,909 stations over a total route length
of more than 63,327 kilometers (39,350 mi).
50,000 coaches and 8,000 locomotives

5. SHED LAYOUT
The shed has a total berthing capacity for 17
locomotives under 4 covered bays. The main bays are:-
•The subassemblies section
•The heavy repair and bogie section(3 berths for heavy
repairs & 2 lifting points)
•Mail running repair bay(6 berths).
•Goods and out of course running repair bay. There was
one old steam shed. This shed had a capacity for
berthing 4 locomotives. This shed was used for light
repairs only. Now a days, a new construction is being on
for new locos of make WDP4 locomotives.

6. DIESEL LOCOMOTIVE
DEPARTMENT

7. DIESEL LOCOMOTIVE
 A diesel locomotive is a type of railway locomotive in
which the prime mover is a diesel engine.
 Several types of diesel locomotive have been
developed, differing mainly in the means by which
mechanical power is conveyed to the driving wheels
(drivers).

8. PARTS OF A DIESEL-ELECTRIC LOCOMOTIVE

9. DIESEL ENGINE
 This is the main power source for the locomotive.
 A diesel engine (also known as a compression-
ignition engine) is an internal combustion engine that
uses the heat of compression to initiate ignition to
burn the fuel that has been injected into
the combustion chamber.
 It comprises a large cylinder block, with the cylinders
arranged in a straight line or in a V.

10. ENGINE VIEW

11. MAIN ALTERNATOR
 The diesel engine drives the main alternator which
provides the power to move the train.
 The alternator generates AC electricity which is used to
provide power for the traction motors mounted on the
trucks (bogies).
 In older locomotives, the alternator was a DC machine,
called a generator. .

12. AUXILIARY ALTERNATOR
 Locomotives used to operate passenger trains are
equipped with an auxiliary alternator.
 This provides AC power for lighting, heating, air
conditioning, dining facilities etc. on the train.
 The output is transmitted along the train through an
auxiliary power line.

13. TRACTION MOTOR
PINION/GEAR
• The traction motor drives the axle through a reduction
gear of a range between 3 to 1 (freight) and 4 to 1
(passenger).

14. FUEL TANK
 A diesel locomotive has to carry its own fuel around with
it.
 The fuel tank is normally under the loco frame and This
huge tank in the underbelly of the locomotive holds 2,200
gallons (8,328 L) of diesel fuel.
SAND BOX
• Locomotives always carry sand to assist adhesion in bad
rail conditions.
• Sand is not often provided on multiple unit trains because
the adhesion requirements are lower and there are
normally more driven axles.

15. AIR COMPRESSOR
• The air Compressor is required to provide a constant
supply of compressed air for the locomotive and train
brakes.

16. RADIATOR AND RADIATOR FAN
 The radiator works the same way as in an automobile.
 Water is distributed around the engine block to keep the
temperature within the most efficient range for the
engine.
 The water is cooled by passing it through a radiator blown
by a fan driven by the diesel engine.

17. TURBO CHARGING
 The amount of power obtained from a cylinder in a diesel
engine depends on how much fuel can be burnt in it.
 The amount of fuel which can be burnt depends on the
amount of air available in the cylinder. So, if you can
get more air into the cylinder, more fuel will be burnt
and you will get more power out of your ignition.
 Turbo charging is used to increase the amount of air
pushed into each cylinder.
 Turbocharging gives a 50% increase in engine power.

23. BOGI ASSEMBLY
SHOP

25. PARTS OF BOGI

26.  BOGIE SHOP
The locomotive bogies are rebuilt with new wheel sets,
suspension bearings and remanufactured traction motors.
Separate shop has been set up for machining of wheel sets and
assembly of locomotive bogies.

27. MACHINES USED IN BOGI
SHOP

28. Asquith CNC Machine
 Computer Numeric Control machines is a closed loop machine.
 As the name depicts these machines use computer for their
operation.
 Computer Numeric Control machines are controlled by a set of
different ISO codes that helps in proper controlling of the
machine.
 In modern CNC systems, end-to-end component design is
highly automated using CAD/CAM programs.

29.  View Of ASQUITH CNC Machine

30.  In this machine all the operation which is essential for
bogi is performes. Mainly these operation are following-
Cutting
Milling
Finishing
Drilling
Fillit
Grinding

31. RADIALARM DRILLING MACHINE
 In radial arm drilling machine there is a one column on
which radial arm is fixed.
 Radial arm are horizontal arm this is movable around the
column. This is main advantage of this machine.
 In drilling machine different type drill can be fixed. But
twist drills are very common in use. Holes of different
diameter can be done by using drills of different diameter.

32. VIEW OF RADIAL ARM DRILLING
MACHINE

33. AXLE TURNING MACHINE
 Axle turning machine is also called lathe machine.
 In this machine material is removed by the single point
cutting tool. Turning of axle, grinding of axle operation
are performed on this machine.

34. RESULT AND CONCLUSION
 The LOCOMOTIVE DIESEL WORKSHOP is the most
widely used transport system in India. The overhauling of the
parts and units of rails forms an important and integral part of
the proper functioning of the railway system in India.
 DCW manufactures large components such as traction motors
and locomotive power packs, rebuilds engine blocks, traction
generators, etc.
