Answer / kiran
From over head transmission line,power taken by pantograph
is fed to rectifier which converts ac to dc and given to dc
series motor.the return path is provided through rails
which is connected to ground by insulating
equipment................

Answer / sandeep maheshwari @
The input supply is 25kv AC through the Pentograph.but the
electric train is run by dc current. so the ac current is
change into DC current by the use of RECTIFIER..& ITS FEED
TO dc SERIES motor.so ELECTRIC TRAIN IS RUN.....

Answer / percy
train gets supply from 25kv line through the pinto above
with this dc is genterated which is supplied to dc series
motor
and the is wheels to tracks and finally to ground

Answer / thowsrf_emerosn
Electric Train Supply or ETS is the supply of electricity
which powers electrical equipment on a train. It is usually
provided by the locomotive, and used to power auxiliary
systems on the rolling stock, usually coaches.
Originally, trains hauled by a steam locomotive would be
provided with a supply of steam for heating the carriages.
When diesel locomotives replaced steam, the steam heating
was supplied by a boiler - either oil-fired, or heated by
an electric element in the case of diesel-electric
locomotives. At this time lighting was powered by batteries
which were charged by a dynamo when the train was in
motion, and buffet cars would use bottled gas for cooking
and water heating.
