BASIC NOTES ON ELECTRIC LOCOMOTIVES:
Two types of power systems are used in OHE systems of Indian Railways electrified sections for operations, they are 1.5KV DC supply and 25KV AC supply, the latter being more widely used than the former and DC traction all set to be phased out soon, with WR turning totally AC now. The OHE power is useless unless we bring an electric loco to use it, so lets get to it now:

One addition to this, huge size and weight of electric loco is not only due to electronics for converting AC to DC or to make 3 phases AC in case of WAP5/7 and WAG-9. There is a huge transformer that is there to make the OHE voltage to correct operating level. OHE supply is never in the range of claimed 25KV, it is off by huge margin, to be tune of up to 7000V on negative side or up to 4000V on positive side in receptive OHE type.

Will get to MU operation with multiple locos only in lead, Lead-Mid, Lead-Aft later.
Multiple Unit: A form where tractive power is derived from one or more places of a rake.
There are a few passenger multiple unit trains which function as local services, a short notes on them:
