3. INTRODUCTION
• Locomotives in india consist of electric and diesel
locomotives. Locomotives are also
called locos or engines.
• An electric locomotive is a locomotive powered
by electricity from overhead lines, an on-board
energy storage device such as a
chemical battery or fuel cell.
• Electricity is used to eliminate smoke and take
advantage of the high efficiency of electric
motors.

4. HISTORY
• 1st Electric locomotive was built by:- a Scotsman, Robert
Davidson of Aberdeen in 1837 & powered by ”BATTERIES”.
• 1st Electric passenger train was presented by:- Werner von
Siemens at Berlin in 1879. Driven by a 2.2 kW motor &
reached a maximum speed of 13 km/h.

5. HISTORY
• Railways first introduced to India in 1853 &
journeyed of 22 miles Between Bombay to
Thane.

6. OVERVIEW OF ELECTRIC LOCOMOTIVE
• Now a days all locos are running
through Electricity with the help of
OHE line.
• Pentagraph is used to connect the
loco with OHE line.
• Loco contains 2 Bogies, each Bogie
consist of 6 wheels. So totally loco
consists of 12 wheels.
• Pantagraph draws 25 KV of
electricity from OHE line, which is
very high AC voltage.

during their normal operation.
• Hence the different auxiliaries provided for
cooling and other purposes. These locos is

28. ADVANTAGES OF THREE PHASE
TECHNOLOGY
• It Require little maintenance.
• 3-ɸ drive allows regeneration and unity power
factor operation.
• It improves operational efficiency besides
reduction in maintenance efforts. The energy
saving due to regeneration and improved
power factor sizable.

29. ADVANTAGES OF ELECTRIC
LOCOMOTIVE
• Electric engines do not produce much heat
and noise.
• Electric engines are therefore easier to
maintain whereas the moving parts of a diesel
engine require constant maintenance.
• The simple nature of the electric engine
makes them efficient and powerful.

30. ADVANTAGES OF ELECTRIC
LOCOMOTIVE
• Electric engines are light weight, constituting
only motors and wheel axles, and have almost
no moving parts.
• Do Not Produce Smock.

31. CONCLUSION
• Main Objective was to learn electric
locomotive In Railways.
• I am thankful to the supporting people of the
POH Bhusawal.
• Electricity is used to eliminate smoke and take
advantage of the high efficiency of electric
motors.
