ACKNOWLEDGEMENT
I would sincerely like to thank the employees and the officers of DLW, VARANASI
for their help and support during the vocational training.Despite their busy schedules,
they took time out for us and explained to us the various aspects of theworking ofthe
plant from the production shops.
I would sincerely like to thank Mr. Arun Yadav (SSE/LTS), Mr. Vipin Srivastava
(JE/LFS), Mr. Arvind Kumar (JE/EES), Er. Ravi Gupta (JE/HMS) who was
instrumental in arranging the vocational training at DLW Varanasi, and without
whose help and guidance the training could not have materialize.
A special gratitude I give to Mr. Saurobh Poddar , whose contribution in stimulating
suggestions and encouragement, helped me to coordinate my project especially in
writing this report.
I express my deep sense of gratitude to Mr. S.P.Singh(Principal, TTC) for given me
such a great opportunity.

ABSTRACT
Indian railways has one of the largest and busiest rail networks in the world Indian
Railways is the state-owned railway company of india.It comes under the Ministery of
transporting over 18 million passengers and more than 2 million tones of freight daily.
Its revenue is Rs.107.66 billion. It is the world’s largest commercial employer, with
more than 1.4 million employees. It operates rail transport on 6,909 stations over a
total route length of more than 63,327 kilometer (39,359 miles).The fleet of Indian
railway includes over 200,000 (freight) wagon coaches and 8,000 locomotive.It also
owns locomotive and coach production facilities .It founded in 1853 under the East
India Company.
India Railway is administrated by the Railway Board Indian Railway is divided into
16 zones.Each zone railway is made up of acertain number of division .There are a
total of sixty-seven dividions.It also operate the Kolkata metro.There are six
manufacturing plants of the Indian Railway. The total length of track used by Indian
Railway is about 108,805km.While the total route length of the network
63,465km.About 40% of the total track kilometer is electrified & almost all electrified
section use 25,000V AC. Indian railway uses four rail track gauges.
The GM Locomotives have been included in the Diesel Locomotive fleet of Indian
railway. Production of GM locomotive has already started in DLW, Varanasi. The
4000 HP, computer controlled GM locomotive has a large number of special and
improved features vis-a-vis the Alco design diesel locomotive presently running in
Indian railway. All those in the field of diesel locomotive need to get acquainted with
the GM locomotive. This book “Introduction hand book on GM locomotive” prepared
by the CAMTECH has been prepared with the purpose of disseminating the
introductory information to all those in diesel loco maintenance field.
