1. Introduction
This locomotive is referred to as the "Heavy Haul" freight locomotive of the Indian
Railways (IR).
This locomotive was conceived owing to the extreme growth in the rail freight
transportation sector.
The growth in this sector is considered to be of great importance in the growth of
the economy of India.
This need had arisen the need for more electrification and electric locomotives in
India. Around 60-65% of the freight haulage of IR takes place on the electrified
section of the Golden Quadrilateral (Indian Railways) & diagonals (which account
for 25% of the route).
These routes are very busy routes, so clearance is a necessity. This power Give it a
great sectional clearance Ability. Thus these locomotives are important for the
Indian Railways.
2. Block Diagram of Electric Locomotive WAG-9
The block diagram was showing every part located in electric locomotive WAG-9.
The parts names and Description are show in below the block diagram (figure 2).

¾ Main transformer
A transformer is a static electrical device that transfers electrical energy
between two or more circuits. A varying current in one coil of the
transformer.
¾ Auxiliary inverter
The Auxiliary Power Converter supplies the auxiliary AC-power needs of the
diesel-electric locomotive.
It charges also the batteries. The unit is installed inside the locomotive. The
unit enables use of maintenance free AC-motors for the auxiliary drives.
¾ Auxiliary rectifier
Power from the motor comes from the on-board electrical supply or,
sometimes, directly from the traction supply.
On electric locomotives, the supply can come from the transformer, via
a rectifier and on a diesel locomotive, from the auxiliary alternator.
¾ Axis brush
A brush or carbon brush is a device which conducts current between
stationary wires and moving parts, most commonly in a rotating shaft.
Typical applications include electric motors, alternators and electric
generators.
¾
3-phase AC motors
A traction motor is an electric motor used for propulsion of a vehicle, such
as an electric locomotive.
An AC induction motor only generates useful amounts of power over
usually, the traction motor is three-point suspended between the bogie, Air
cooling, Electric vehicle battery. Induction motor & Three-phase AC.
¾ Motor blowers
An electric locomotive consists of various equipment.
Traction motor cooling blower and its motor is one of the important
auxiliary machine.
There are two traction motor cooling blowers fitted in a locomotive. Each
for cooling of one group of three traction motors.
¾ Compressor
The compressor itself consists of a pump driven by an electric motor.
7
¾ Cooling fans
Locomotive radiators keep engines cool. The radiator system is intended to
keep the engine operating at nearly the same temperature, regardless of
the ambient air outside the locomotive.
¾ Main rectifier
Rectifier, A converter consisting of thyristors and diodes which is used to
convert AC to DC. A modern locomotive will usually have at least two, a
"Main Rectifier" for the power circuits and one or more for the auxiliary
circuits. Relay a remotely controlled switch which uses a low voltage
control circuit.
¾ Circuit breaker
An electric train is almost always provided with some sort of circuit
breaker to isolate the power supply when there is a fault, or for
maintenance. On AC systems they are usually on the roof
near the pantograph. There are two types - the air blast circuit
breaker and the vacuum circuit breaker or VCB.
¾ Pantograph
A pantograph is an apparatus mounted on the roof of an electric train, tram
or electric bus to collect power through contact with an overhead line. It
is a common type of current collector. Typically, a single or double
wire is used, with the return current running through the track.
¾ Main inverter
An electric locomotive is a locomotive powered by electricity from
overhead lines, a third rail or on-board energy storage such as a battery or
a super capacitor. Newer electric locomotives use AC motor-inverter drive
systems that provide for regenerative braking.

Maintenance Service Level-1 Graph 15.
In this maintenance service we have the five loco service in Kazipet junction and
we are showing the each loco travel time and maintenance service by three days
in the below graph 15.
Graph-15 Maintenance Service level-1.

From graph 15, The loco-1 start from the 6am to 24pm (day-1) and the
maintenance service are from 24pm to 6am of day-1, And the same process for
the day-2 and day-3 loco.
But the each loco time differents of 2hrs, time to start the loco from the starting
point. And we have indicates the travel time and the maintenance service in
colour boxes to appear clearly.
9.3. Maintenance Program of the locomotive
In this maintenance program of the locomotive was showing the traveling time
was calculated accurately and we showing below table-9.

Initial From Khammam to Kazipet 1hr 90mins in 1st day with a wagon speed of 300
km, From Kazipet to Hyderabad it takes 1hr 62mins, overall wagon takes 3hr
52mins.
For every electric locomotive there are the schedules for driving the locomotive
drivers.
We have five electric locomotive that are shown in graph-14, in the schedules the
drivers are taken charge by one of one for each locomotive, therefore 12
members of drivers are taken charge by electric locomotive.

10. Electric Loco Shed Kazipet Maintenance
The workshop now handles Maintenance of 200 Locomotives. It has highest
reliability of engineers with a meagre manpower of 2.56 persons Per Loco.
The electric loco shed of the South Central Railway, Constructed Initially at a
cost of Rs.25Crore (3107039 Euros) here, Completed 20years of operations.
Starting with an initial holding of 72 Locomotives, It now handles maintenance of
200 Locomotives that Includes both passenger and good trains, Each with a Power
of a whopping 6000 horsepower.
42
Also Included in the list of trains are Rajadhani, Duronto and Sampark
Kranthi Express Service , Mr.Agrawal said the shed, With a head count of about
700 persons was able to carry out maintenances of locomotives with best practies
on the Indian Railways with the highest reliability of engineers with a meagre
manpower of 2.56 person per loco.
The shed takes care of wide area multipurpose (WAM), Wide area passenger
(WAP), and wide area goods (WAG) engines with a schedule of one full
maintenance onces in three months. It was transformed into a workshop to
handle maintenance of electric engines.
These all are the maintenance of electric loco shed Kazipet.
11. Suggestions to people.
When we are enter in the electric loco shed there have highly security to check
the people and enter in to electric loco shed.
1) 30% of the respondents are not identified for new assignments so extend their
assignments by providing proper training to the employees.
2) 30% of the respondents are dissatisfied due to lack of recognition and rewards.
A positive recognition for work boosts the motivational level of employees.
Recognition can be made explicit by providing awards like best employee of the
month.
3) Provide opportunities for career personal growth through training and
education, challenging assignments and more.
4) Identify the key performance areas of the individuals and conduct training
program to develop their skills and knowledge.
43
5) Immediate resolution of the grievance is necessary otherwise it will effects the
Productivity of the organization so immediate actions should be taken to resolve
the grievance of the employees.
12. Conclusion.
9 Main objective was to learn electric locomotive in railways.
9 Electricity is used to eliminate smoke and take advantage of the high
efficiency of electric motors.
9 We calculate the value of electric loco locomotive WAG-9
components, weight, volume.
9 As well as we proof the power supply of electric locomotive WAG-9.
9 We proof the calculation part about, and by showing the graphs, at
last we find the new railway service.
9 We prove the new railway service, Travel time, Time table,
Locomotives, Maintenances.
9 By the electric locomotive I learn the components of locomotive & I
got lot of experiences to research the electric locomotive by the
process.
