Electric train?

Question

its working principle,parts

Answer 1

Electric trains start by collecting electricity from the track, third rail or overhead wire.

On real trains, voltage is 600, 900, 1500 or 3000 volts DC typically... or 11000, 25000, or 33000 volts AC (in which case the train has a transformer to reduce the voltage to 600-1500V.)  

On model trains, it's around 12 volts.

From this point forward, electric locomotives work exactly the same as diesel-electric locomotives.

Then power flows through "switchgear" which is either electromechanical or electronic, and controls how much power is sent to the motors.

Finally power goes to electric motors.  On real trains there is usually one motor per axle, nose-hung on each axle with a very simple gear drive to the wheel.  On models there is usually one motor with a more complex gear drive to the wheels.

On real trains it's controlled from the cab of a locomotive.  On models it's remote controlled by varying the track voltage, or by sending coded signals down the track circuit.

Answer 2

its working in d.c series motor principle will be same like d.c series motor .. here some of applications are followed like breaking.. etc...
