electric train?

Question

its working principle,parts

Answer 1

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...

Answer 2

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 3

Rango is the only person who answered above who has the faintest clue what he is talking about. Please ignore all the answers so far other than Rango's and mine. Almost all diesel locomotives are also electric, but they carry their own generating plant with them, rather than relying on the overhead wires for their source of power. The diesel engine and generator are like a power station on wheels. I have no idea from what planet some people have gotten the idea that electric trains are not as safe as diesel trains. That simply is not connected to reality. Pure electric trains are just as safe as diesel trains if not in some cases more so. The advantages of pure electric locomotives include higher performance, cleaner environmental output, and less noise. Note: The electric locomotive itself does not give off very much at all in the way of polluting smoke or gasses, but remember that the overhead wires are energized from the power grid, which means they actually use electricity from coal, oil, gas, and nuclear plants, as well as potentially solar, wind, and hydro power sources. So right now they pollute just about as much as diesel locomotives. Overhead wire systems may incorporate one or two overhead wires, depending on the system in use. Overhead wiring is very costly to install and maintain. Diesel locomotives have a higher initial cost, and may be more costly to maintain, but have the advantage of being able to go anywhere the track is heavy enough, without needing overhead wires. So the trade-offs are about equal at this point, but in future years as the cost of fossil fuels continues to increase, electrics will continue to become more advantageous in terms of cost.
