How do electric train work – From MUMBAI to NEW DELHI – Indian Railways and High Speed Trains


how do electric trains work a journey
from Mumbai to New Delhi a train is a form of transport consisting of a series
of connected vehicles that generally runs along a railroad track to transport
cargo or passengers it represented a turning point in history that changed
the world forever without trains and railroads the world would be an
altogether different place these marvelous machines structured the social
physical and economic foundations of many nations cities began to organize
around newly constructed stations that became icons in themselves like some
sort of sanctuaries representing the pleasures of travel in this video we will explain the
working principle of electric trains through the travel made by the JAES
CEO who will leave the city of Mumbai to reach New Delhi with over 200 years
of innovation and improvement the train industry managed to grow from it’s
simple steam trains through diesel trains electric trains up to modern
high-speed trains and maglev trains the first Indian electric train maid was
introduced on February 3rd in 1925 right at the Mumbai station Indian Railways is
the fourth largest railway network in the world by size with a route length of
40 1861 miles it carries over 23 million passengers every day the JAES CEO is
at the Central Station of Mumbai the jetter Abbate Shivaji terminus is one of
the most iconic terminal train stations and is a unesco world heritage site
here the CEO gets on a train with electric locomotion electric trains
unlike steam trains or diesel trains do not carry fuel or water on board but
instead they use electrical power as one of the most reliable sources of
propulsion a catenary system in fact is used to transmit electricity to the
Train this electricity is produced hundreds of miles away from the railway
and it is carried to the overhead line thanks to transformers you can watch the
video about the working principles of transformers by clicking the link at the
top of the right corner of this video the electricity flowing through the
overhead line is an alternating current and it usually has a voltage of 25 kilo
volts when the train is ready to go the pantographs which are placed on the
roof of the locomotive are pushed up with the help of air pressure
the head is the only part of the pantograph to touch the wire pick up the
current is collected via meant alized carbon strips on the head plus the
zigzag configuration of the overhead contact wire ensures a symmetrical wear
of the head surface the voltage collected from the overhead wire passing
through the transformer completes the circuit on the rails using brushes on
the axis of the wheels transformers and rectifiers inside the locomotive are
used to modify the parameters of the electrical power taken from the overhead
line so that the onboard inverters can generate a three-phase alternating
current in order to transfer the power to the wheels and obtain the right
traction power to move the train furthermore the auxiliary inverters
supply the necessary current to power the onboard equipment and instruments
like cooling fans necessary for lowering the temperature of transformers and
motors accumulators which need to be constantly charged in order to sustain
the startup phase and power the basic electronic systems even in the absence
of a power supply compressors which are very important devices useful to provide
compressed air compressed air is an essential element that powers many of
the most vital functions of a train without compressed air in fact a train
would be unable to raise or lower its pantographs open and close its doors
properly or even engage the sand box which is a container filled with sand
usually placed in front of the driving wheels of the locomotive in order to
drop the sand on the rail in wet and slippery conditions and on steep grades
to improve traction even the brakes operate through air pressure basically
the train brakes are always on for this reason a brake pipe delivers pressure to
the brakes putting them in the running position and letting the train move
on the contrary if the brake pipe stops delivering pressure the brakes will be
in the release position and the train will simply stop each wagon is provided
with the brake all the brakes work simultaneously in this way if there were
any leaks in the compressed air system the brakes not having the required
pressure will simply stop the train preventing accidents the extensive
network of Indian Railways passes through dense forests which represent a
natural habitat for many species of wild animals in India but the rise of the
speed of the trains and the consequent risk of train accidents is putting these
beautiful areas in danger India has been involved in train accident prevention
programs for many years now with the aim of protecting the wildlife of these
natural reserves which are considered national treasures the bogey of the
Train is a chassis or framework that carries the running gear the supporting
structure connected to it and the traction motors usually three-phase AC
motors you can watch the video about the working principle of three-phase motors
by clicking the link at the top right corner of this video in an electric
train the engines are located in the bogies of
the locomotive a locomotive can have many bogies and so it can be more or
less powerful each train car is equipped with two bogies this allows a quick
disconnection of the train cars in any station as well as a more simple
maintenance work during a train breakdown unlike traditional electric
trains the engines of high-speed trains are distributed on each bogie
differently also they have different types of bogies called Jacob’s bogies
Jacob’s bogies are not to be found underneath a piece of rolling stock but
they are placed between two car body sections the weight of each car is
spread between the Jacob’s bogie this arrangement provides the smooth
ride of Bhogi carriages without the additional weight and drag
despite their safety features lower weight and simpler and cheaper
construction with Jacob bogies the vehicles are semi-permanently coupled so
they can only be separated in the workshop 10 years in the industrial supply
sector have led JAES to become a qualified partner for some of the most
important railway companies providing its technical support over a wide range
of industrial components necessary during the production process of these
incredible machines Indian Railways is exploring the possibility of a
SuperSpeed also called ultra high-speed rail network in India the future
standard is represented by high-speed trains which will be always powered with
a 25 kilo volts AC railway electrification system these types of
trains will be way more efficient than the actual electric trains after this
long journey the JAES CEO finally arrives in the beautiful city of New
Delhi which over the last few years becomes a dynamic mashup of past and
future and a crossroads of tradition and innovation finally if you found this

  1. Hey JAES, awsome video. I have always wondered how they work! Just the explanation I was looking for! And the 3d animation added more awesomeness! I have one question though…What animation software do you guys use? An answer would be really appreciated. 🙂 Hoping to hear from you soon! 🙂 🙂

  2. I m German and this video is Great I hope everyone can be interested can you tell me how long it take make this video ?

  3. Dear Jaes I visit your website https://www.jaescompany.com/?lang=en and is really nice congratulation and thanks for all your video

  4. Indian railway very useful transport system in India. Indian trains very very longer trains .indias railway journey awesome i love indian trains. local train🚞. express 🚅and metro🚇 . indian trains very comfortable and safe journey. Iam like this video amazing😄😄😄 make more train video s

  5. I've always wondered why the overhead contact wire cannot provide AC since the train motors run on AC power? There wouldn't be a need for transformers, inverters and so on…by directly connecting the electric line to the motors!
