LOCOMOTIVE
A locomotive or engine is a
rail transport vehicle that
provides the motive power
for a train.

ENGINES
1.Steam Engine 2.Diesel Engine 3.Electric Engine

STEAM ENGINE A steam locomotive is a
locomotive that provides the
force to move itself and other
vehicles by means of the
expansion of steam.It is fuelled
by burning combustible material
(usually coal, oil or, rarely, wood)
to heat water in the locomotive's
boiler to the point when it
becomes gaseous and its
volume increases 1,700 times.
Functionally, it is a steam engine
on wheels.

DIESEL ENGINE A diesel locomotive is a
type of railway locomotive
in which the prime mover
is a diesel engine. Several
types of diesel
locomotives have been
developed, differing
mainly in the means by
which mechanical power
is conveyed to the driving
wheels.

ELECTRIC ENGINE An electric locomotive is a
locomotive powered by
electricity from overhead lines,
a third rail or on-board energy
storage such as a battery or a
supercapacitor. Locomotives
with on-board fueled prime
movers, such as diesel engines
or gas turbines, are classed as
diesel-electric or gas turbine-
electric and not as electric
locomotives, because the
electric generator/motor
combination serves only as a
power transmission system.
