7. LOKMANYA 5

8.  CLW ,located in the land of VISWA BHARTI ,a great educational & cultural
seat in the world is the premier electric loco producer in this country.
 On the 9th january1948,survey of the proposal area was done.
 The production of Electric Locomotives commenced in 1961. In the process,
fifteen versions of electric locomotives were produced by CLW and the latest in
that series is the freight locomotive WAG-7 and
passenger locomotive WAP-4. Pandit Jawaharlal Nehru, the first
Prime Minister of India, commissioned the first 1500 V dc Locomotive
named “LOKMANYA” on the 14th October, 1961.The production of
25 kV ac loco commenced on 16th November, 1963.
 The first Electric Loco turned out from CLW, christened as “BIDHAN” was a
broad gauge 25 kV ac. Freight Locomotive (WAG-1) of 2840 hp with
maximum speed of 80 km/hr. Subsequently CLW gradually upgraded the
horsepower of Electric Loco from 2840 hp to 6000 hp and maximum speed
from 80 Km/h to 160 km/h.
 CLW also built 25 kV ac/1500 V dc, ac/dc Loco, WCAM-1 for hauling Mail /
Express Trains from BRC to BCT on Western Railway.
 The loco works was initially established for production of 120 average sized
steam locomotives with the capacity of manufacture 50 spare boilers.

15. TRANSDUCER

16.  Transducer is a device that convert a signal in
one form of energy .
 Energy types includes electrical , mechanical ,
electro (include light) magnetic and thermal
energy.
 The term transducer implies the use of a
sensor/detector , any device which converts
energy can be considered a transducer.
 Transducer are widely used in measuring
instrument.

17. PENTOGRAPH
Pantograph is an
instrument used to
reproduce to an enlarge
or a reduce scale.
A pantograph is mostly
used for the
reproduction of planes
etc , on enlarge or
reduced scales.
A modified form of
pantograph is used to
collect power at the top
of an electric locomotive.

18. ROOF LINE
A roof line is used to
describe the fascia , saffits ,
bargeboards and cladding
that forms the frontage
immediately below the roof
and the eaves of most
homes.
Fascia is a term used in
architecture to refers to a
frieze or band running
horizontally and situated
vertically under the roof
edge .

19. RESISTER HORMONIC
FILTER
The harmonic filter
resister are used to
eliminate the
dangerous
distortion(harmonic
s) generated inside
the network due to
connection of more
and more number of
electronic power
convertor

21. PENUMATIC
HORN
Loco horn is an air horn
Loco horns are operated
by compressed air
,typically 8.6 to 9.6 bar and
fed form a locomotive main
air reservoir.
The engineer open the
horn valve , air flow
through a supply line into
the power chamber at the
base of the horn.
It passes through a
narrow opening b/w a
nozzle and circular metal
diaphragm in chamber and
vibrate and to produce
sound.

22. SPEEDOMETE

It is an instrument
that measures the
speed of locomotive.
Some speedometer
are round with
numbers and a
pointer like that of
the hands on a clock
