History : ABOUT CHITTARANJAN LOCOMOTIVE WORKS
Chittaranjan Locomotive Works (CLW) is the dream of the nation’s visionaries,
coming true. The planners of the Nation with their deep insight and foresight set to
build a Loco building Factory in West Bengal and CLW is that vision, coming true. On
the 9th of January 1948, survey of the proposed area was done.
The rocky soil was an advantage in
erecting foundations for heavy structural
work and the undulating terrain solved
the problem of drainage for the
township while the schemes of the DVC
envisaged hydro-electric and thermal
power stations in the vicinity assured
cheap power availability in the near
future. It is the only major Electric
Locomotive builder in the country. It is
situated just at the Border of West
Bengal and Jharkhand and is at about
32 km from Asansol and 237 kms from
Kolkata.
The place where today CLW is situated
was actually a hamlet of small villages.
The locoworks with its ancillary
workshops has a stores purchase office
in Kolkata and inspection cells in New
Delhi, Mumbai, Kolkata and Bangalore.
During pre-construction days
The Workshop has an area of 18.34 Sq. Km. The issue of setting up a loco building
unit continued to be under active consideration of the Central legislature and in the
late thirties, a committee consisting of M/s. Humphries and Shrinivasan was
appointed to investigate the possibility of establishing a locomotive manufacturing
unit and to consider its economic viability. The initial project, at Chandmari, a place
near Kanchrapara, in the state of West Bengal, could not mature due to partition,
which inevitably necessitated a change of site. This present site at Chittaranjan was
selected after a fresh survey and Railway Board’s approval was obtained in the year
1947. The locoworks was initially established for production of 120 average sized
steam locomotives with the capacity to manufacture 50 spare boilers.
History : ABOUT CHITTARANJAN LOCOMOTIVE WORKS
The production of Diesel Hydraulic Locomotives was taken up during 1968. After
manufacturing 2351 Steam Locomotives of 5 types and 842 Diesel Hydraulic Locos
of 7 types, production of steam and diesel hydraulic locos were discontinued from
1973-74 and 1993-94 respectively

manufacturing 2351 Steam Locomotives of 5 types and 842 Diesel Hydraulic Locos
of 7 types, production of steam and diesel hydraulic locos were discontinued from
1973-74 and 1993-94 respectively
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 14
th
October, 1961.
The production of 25 kV ac loco
commenced on 16
th
November, 1963. The
first Electric Loco turned out from CLW,
christened as “BIDHAN” was a Broad
Gauge 25 kV a.c. 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 W.Rly.
Lokmanya’ WCM-5
CLW became the first production unit in the developing countries, second in
Asia and fifth in the world to manufacture 3-phase state of the art GTO
Thyristor controlled Electric Locomotive and the first indigenous 6000 hp
freight electric loco WAG-9 christened as “NAVYUG” was turned out on 14
th
November, 1998. During the year 2000-01 the first passenger version of three
phase loco WAP-5 called “NAVODIT”, with maximum service speed of 160 km/h
and having a potential upto 200 km/h, has been manufactured. Developments of
sources, indigenisation and cost reduction of three-phase loco have been the
highest priority items. The towering imported cost of Rs. 35 crores for 3 phase loco
has been drastically brought down to about Rs.12.5 crores.
History : ABOUT CHITTARANJAN LOCOMOTIVE WORKS
Production of DC Traction Motors and Control Equipment commenced in April, 1967.
Currently both DC & AC traction motors are being manufactured. Steel foundry was
set up in 1962-63 for manufacture of cast steel loco parts. CLW has in house
facilities for machining and assembly of wheel sets, fabrication and machining of
bogies etc. The facilities include modern CNC machines, plasma-cutting machines,
inert gas welding sets etc

River Ajay flows past CLW along its
northern side. Workshops, offices and
quarters are spread over the whole are
with ample space in between –
surrounded by greenery and trees.
There are several water bodies in CLW
exhibiting a lush green environment
which attract a large number of
migratory birds every year. A variety of
flora and fauna can be seen here all the
year round.
Long before others became environment
conscious, CLW administration started
planting trees, thus turning and arid
area into a green one. In 1996 alone
90,000 saplings were planted with the
help of the Social Forestry Division of
Government of West Bengal. In 2005
also 50,000 saplings have been planted
with the help of same agency. The
Administration is regularly educating the
staff and encouraging them to preserve
the environment. Recently, an immense
amount of work has been done, with a
view to conserve the Environment, as
well as using of all the existing natural
resources in an eco-friendly manner.
LOCO ASSEMBLY SHOP
The efforts have been recognized by the World Environment Foundation and the
Golden Peacock award for Environment Management 2006, has been
conferred on 9
th
June 2006.
CLW has complied fully with the provisions of the Industrial Safety Act, 1948. CLW
in its safety policy aims to ensure 100% safety for all workers working in
Chittaranjan Locomotive Works. CLW is the proud recipient of the Safety
innovation award 2006. The award was conferred on CLW on 6
th
September, 2006 by the Safety and Quality forum of the Institute of
Engineers (India).
CLW has recorded the best ever performance during 2007—08 in terms of outturn
of locos and financial indices. The year 2007-08 culminated with the inventory under
stores at Rs. 161 crores as against the target of Rs. 172 crores communicated
through Final Grant for 2007-08, which has resulted in an all time low stores turn
over ratio of 10.75 as compared to 12.69 of the previous year.The WMS turn over
ratio has also decreased to 5.61 in comparison to that of 2006-07 which was 8.67.
The target of Rs. 284 crores for manufacture of components was surpassed and the
figure was Rs. 315 crores. The target of Rs. 85 crores ,for sale and transfer of
bought out items has been fully achieved. Auction sale proceeds exceeded Rs. 8
crores. Full credit of Rs. 1500 crores has been realized under Board’s RSP for 200
locomotives as per target given by Railway Board. The target of Rs. 19 crores kept
for supply of cast items (HS CASNUB Bogie) has been fully achieved.With all these
the net plan outlay is likely to be Rs. 32 crores only which is much below
northern side. Workshops, offices and
quarters are spread over the whole are

WAG9
WAG-9 - The “Heavy Haul” Freight locomotive of IR:-
Rail Freight market which is registering a
remarkable growth since 2000, has also triggered
a buoyancy in demand for Electric Freight
locomotives. Almost 60 – 65 % of IR’s freight
handling takes place over IR’s Electrified Golden
Quadrilaterals and Diagonals , though it accounts
for only 25 % of its route kilometrage . Golden
Quadrilateral and Diagonals being saturated
routes, need heavy throughput and faster sectional
clearance. This is where these heavy haul and
speedier WAG-9 locos play a significant role. This
Gem of a loco is indeed a rail operator’s
delight.This six axle loco with axle and nose
suspended drive is designed to give a starting
tractive effort of 460 KN and maximum braking
effort of 260 KN. Rated 6000 hp, the loco has also
been successfully adapted to give 508 KN of
starting tractive effort with additional ballast.
This loco also is capable to give 6000 hp on rail
upto its rated speed of 100 kmph which gives

Rail Freight market which is registering a
remarkable growth since 2000, has also triggered
a buoyancy in demand for Electric Freight
locomotives. Almost 60 – 65 % of IR’s freight
handling takes place over IR’s Electrified Golden
Quadrilaterals and Diagonals , though it accounts
for only 25 % of its route kilometrage . Golden
Quadrilateral and Diagonals being saturated
routes, need heavy throughput and faster sectional

How to reach CLW
Layout map
Chittaranjan Locomotive Works (CLW), located in the land of Viswa Bharati , a great
educational and cultural seat in the world, is the premier electric loco producer in this country.
Situated at the border of West Bengal and Jharkhand, it is about 32 kms away from Asansol and
237 kms from Kolkata, the state capital. The place where CLW is situated today was a small
unknown hamlet of Santhals in the pre-industrialization era. Once the construction of the loco
unit started, a wave of all round development reached this distant place and gradually it has
become a modern railway township equipped with all modern facilities. Spread over an area of
18.34 sq. kms , CLW houses workshops, offices, schools college, staff quarters, cinema hall,
indoor stadium and auditorium.
Apart from its expertise in rolling out state- of-the-art electric locos and providing Indian
Railways much needed motive power, Chittaranjan is also a hot spot for nature lovers, and all
those who want to soothe their frayed nerves in the lap of mother nature. Its serene
environment, lush green fields and plethora of unknown birds welcome all visitors. It’s ideal to
visit Chittaranjan from November to March every year. Every winter, migratory birds, after
covering thousand miles come to the seven lakes within the township. If you are a nature lover,
you will surely be delighted to get a glimpse of CLW’s flora and fauna. Come and explore this
treasure trove.

Steel Foundry manufactures steel castings generally complaint with
grades IS-1030 and AAR-201. To meet the requirements of different
products, Steel Foundry had earlier been processing eight different grades of
metal. Steel Foundry has been successful in rationalizing the same to five
grades only without affecting any metallurgical, chemical or physical
properties. This has resulted in improvement in productivity.
Different grades of steel for castings are as follows:-

NEW ELECTRIFICAL ENGINES
THREE PHASE ELECTRIC LOCOMOTIVES
(a) Need
Indian Railways imported 2900 HP passenger and freight locomotives alongwith transfer of
technology from 50 cycles group in France in the year 1960. The indigenous production of locomotive
was taken up at CLW in the year 1965. Indian Railways have been continuing with this technology for
over 30 years and during this period improved it to optimise its use to produce 5000HP freight and
passenger locomotives. Further upgradation was not possible. With the increase in train loads and need
for higher speeds both for passenger and freight to enable hauling of more traffic with existing
infrastructure, it became important to upgrade existing technology of electric locomotives and, thus IR
decided to go for most modern three phase high horse power electric locomotives.
(b) Acquisition
IR have acquired 30 nos (10 passenger and 20 freight) high horse power ?state of the art?
microprocessor controlled GTO thyristor based three phase drive electric locos from M/s Bombardier
