PREFACE
The objectives of the practical training are to learn
something about industries practically and to be familiar with
the working style of a technical person to adjust si mply
according to the industrial environment.
It is rightly said practical life is far away from theoretical
one We learn in class roo m can give the practical exposure or
real life experience no doubt they help in i mproving the
personality o f the , b ut the practical exposure in the field will
help the st udent in long run o f life and will be ab le to
imp lement the theoretical knowledge.
As, a part o f academic syllabus of four year degree
course in Mechanical Engineering every student is required to
undergo a practical training.
I am st udent of third year mechanical and this report is
written on the basis of practical knowled ge acquired by me d uring
the period on the basis of practical knowled ge acquired by me d
uring the period of practical training taken at Diesel Locomotive
Works, Varanasi.
INTRODUCTION
Diesel Locomotive Wo rks (DLW) is production unit under the
ministry of railways. This was setup in collaboration with American
locomo tive co mpany (ALCO) USA in 19 61 and the first locomotive
was rolled out in 196 4. This unit produces diesel electro nic locomotives
and DG sets for Indian railways and ot her customers in India and
Abroad.
Subseq uent ly a contract for transfer of techno lo gy of 4000 HP
Microprocessor Controlled AC/AC Freight (GT 46 MAC) / passenger
(GT 46 PAC) locomot ives and family of 71 0 engines has been signed
with electro motive divisio n of general mo tors of USA for manufacture
in DLW. the prod uction of these loco motives has now started and thus
DLW is the only manufacturers of Diesel Electric Locomo tives wit h
both ALCO and General motors technologies in the world.
Brief History
The Diesel Locomotive Works (DLW) in Varanasi, India, is a
production unit owned by Indian Railways, for which it manufactures
diesel-electriclocomotives and spare parts.
Founded in 1961, the DLW rolled out its first locomotive three
years later, on January 3, 1964. It manufactures locomotives which are
variants based on the original ALCO designs dating to 1960s and
the GM EMD designs of the 1990s. DLW has an annual production
capacity of 150 locomotives and plans to increase it to 200 based on the
current demand.
DLW locomotives have power outputs ranging from 2,600
horsepower (1,900 kW) to 4,000 horsepower (3,000 kW). Currently
DLW is producing EMD GT46MAC and EMD GT46PAC locomotives
under license from Electro-Motive Diesels (formerly GM-EMD) for
Indian Railways.
Varanasi, one of the oldest populated cities in the world and has a
promising place in the international ground both as a hub of traditions
and technology. One side the humming of divine and holy bells of the
temples brings the city to life; on other side Diesel Locomotive Works
(DLW) Varanasi is one of the largest industrial unit in eastern part of the
nation. DLW catch the attention of lot of foreign tourist students to
observer on going amazing locomotive manufacturing process in
Varanasi. Diesel Locomotive works Varanasi is located at the North end
of the city and about 8 Km away from the Holy River Ganges Ghats.
DLW is an ISO 9002, ISO 14001 & OHS 18001 Certified Organisation .
Diesel Locomotive Works, Varanasi (DLW) is one of the main
manufacturing units run by the Indian Railways. This manufacturing
unit came into existence in year 1961, as a “Green Field Project” in
industrial association with ALCO, USA. This unit generate all the Diesel
Electric Locomotives. In year 1964, the first locomotive was
manufactured and it was devoted to the country. Diesel Locomotive
Works, Varanasi produces only Electric Diesel locomotives and
auxiliary parts of locomotives. However it is an Indian corporation but it
has supplied locomotives to some foreign countries also, includes

Fixtures are used to ensure proper fitting of components and quality welding in subsequent stages.
BOGIE MANUFACTURING
Special purpose machines are utilised for machining cast and fabricated bogie frames. Axle and wheel disc machining is undertaken on sophisticated CNC machines. Inner diameter of wheel discs are matched with the outer diameter of axles and assembled on wheel press. The complete truck (bogie), including bogie frames, wheels and axles, brake rigging and traction motors are assembled which is ready for application to locomotive.
LOCOMOTIVE ASSEMBLY
Tested engines are received from Engine Division. Similarly under-frames are received from Loco frame Shop and Assembled trucks from Truck Machine Shop. Superstructures and contractor compartments are received from respective manufacturing and assembly shops of Vehicle Division. Important alignments like crank shaft deflection, compressor
alignment and Eddy Current clutch/radiator fan alignment are done during assembly stage.
Electrical control equipments are fitted and control cable harnessing is undertaken. The complete locomotive is thus assembled before being sent onwards for final testing and painting.all locomotive systems are rigorous tested as per laid down test
procedures before the locomotive is taken up for final painting and dispatch.
Block Division
Flame Cutting of Components
Steel plates are ultrasonically tested before being precision cut by numerically controlled flame cutting machines, Plasma Cutting Machine. Components are straightened and machined prior to fitting & tacking on fixture designed specially for engine block fabrication to ensure close tolerance on engine block.
Fabrication of Engine Block
Components after flame cutting and various machining operations are fit and tack welded before taking on rollovers. Heavy Argon-CO2 welding is done on these rollovers. High quality of welding is done by qualified welders. Weld joints are subjected to various
tests like ultrasonic, X-rays, Visual etc.
Down-hand welding is ensured using specially designed positioners.
Fabrication of engine block is completed by submerged arc welding using semi-automatic welding machines. Special fixtures are used for making down-hand welding possible in inaccessible areas. Critical welds are subjected to radiographic examination. All welders are periodically tested and re-qualified for the assigned.
After complete welding weldment is stress relieved and marking is done for subsequent machining.
