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

SHED LAYOUTThe 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.

DIESEL LOCOMOTIVE DEPARTMENT

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).

PARTS OF A DIESEL-ELECTRIC LOCOMOTIVE

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.

ENGINE VIEW

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. .

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.

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).

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.

AIR COMPRESSOR

• The air Compressor is required to provide a constant

supply of compressed air for the locomotive and train

brakes.

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.

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 theamount of air available in the cylinder. So, if you canget more air into the cylinder, more fuel will be burntand you will get more power out of your ignition.

Turbo charging is used to increase the amount of airpushed into each cylinder.

Turbocharging gives a 50% increase in engine power.

BOGI ASSEMBLY

SHOP

PARTS OF BOGI

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.

MACHINES USED IN BOGI

SHOP

Asquith CNC MachineComputer 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.

View Of ASQUITH CNC Machine

In this machine all the operation which is essential for

bogi is performes. Mainly these operation are following-

Cutting

Milling

Finishing

Drilling

Fillit

Grinding

RADIAL ARM 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.

VIEW OF RADIAL ARM DRILLING

MACHINE

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.

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.
