CHITTARANJAN LOCOMOTIVE WORKS

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 was 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-9i and passenger locomotive WAP-7. Pandit Jawaharlal Nehru, the first Prime Minister of India, commissioned the first 1500 V dc Locomotive named /LOKMANYA/ o­n 14th October, 1961. The production of 25 kV AC DC loco commenced o­n 16th 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.
CLW became the first production unit in the developing countries, second in Asia and fifth in the world to manufacture, state of the art, 3-phase GTO Thyristor controlled Electric Locomotive and the first indigenous 6000 hp freight electric loco WAG-9. This was  christened as /NAVYUG/  and was turned out o­n 14th November, 1998. During the year 2000-01 the first passenger version of three phase loco WAP-5  /NAVODIT/, with maximum service speed of 160 km/h and having a potential upto 200 km/h, was manufactured. Development of sources, indigenisation and cost reduction of three-phase loco have been the highest priority items. The cost of 3 phase loco has been drastically brought down from a high of Rs. 35 crores for imported locos to about Rs.12.5 crores. It is hoped that this will further be reduced, if the number of such locomotives manufactured by CLW is increased.
