Indian Railways WCAM Class
WCAM (W -broad gauge ; CA -Both DC and AC ; M -for both goods and passenger service) is the dual-power AC/DC series locomotive used by Indian Railways. These locomotives can run under both DC traction and AC traction. All the WCAM locos were made by BHEL. They have 750V DC traction motors, using resistance banks in DC mode and a variable ratio auto-transformer with rectifier units in AC mode, for power control.
The WCAM class locomotives are in service only in the Mumbai region. The dual-voltage WCAM series locomotives haul intercity trains out of Mumbai DC suburban region which is still on a 1500V DC overhead system, as opposed to other parts of India which have 25000 V AC overhead.
Central Railways section only needs the change-over for the traction, being DC inwards near Mumbai and AC on the outer side.
Western Railways doesn't need WCAM Locos now because Western Railways Mumbai section has been converted to AC Section. On the Central Railway line they are in service on Mumbai - Igatpuri line. Sometimes they travel to Manmad.
Western Railway has converted the Mumbai region's 1500v DC traction to 25000v AC traction. This has result in the elimination of the need to change engine's at Vadodara & WAP engines have started entering the Mumbai region.

Famous quotes containing the words indian, railways and/or class:
“The Indian remarked as before, “Must have hard wood to cook moose-meat,” as if that were a maxim, and proceeded to get it. My companion cooked some in California fashion, winding a long string of the meat round a stick and slowly turning it in his hand before the fire. It was very good. But the Indian, not approving of the mode, or because he was not allowed to cook it his own way, would not taste it.”
—Henry David Thoreau (1817–1862)
“There is nothing in machinery, there is nothing in embankments and railways and iron bridges and engineering devices to oblige them to be ugly. Ugliness is the measure of imperfection.”
—H.G. (Herbert George)
“... in the fierce competition of modern society the only class left in the country possessing leisure is that of women supported in easy circumstances by husband or father, and it is to this class we must look for the maintenance of cultivated and refined tastes, for that value and pursuit of knowledge and of art for their own sakes which can alone save society from degenerating into a huge machine for making money, and gratifying the love of sensual luxury.”
—Mrs. H. O. Ward (1824–1899)
