Answer / prashant

in track electrification actually the power is supplied
from the over head line while the tracksthemselves acts as
the return conductor

Answer / amit rajak

in india we actually uses single conductor for track
electrification. aswell the railway track or track which is
itself a conductor acts as the return conductor.

it has the following advantages.
1).easy handling.
2).smooth control where the train track terminates.
2).low cost aS only single conductor is used.
4).low losses as if there is two or more than
two wire system the overall loss
will be high
5). high efficiency.
6).safe as the risk of breaking of conductor is high

explain about the electrification in the Indian Railways? ie., how the power is taken and used to drive the train? explain with the block diagram??
