- Indian_locomotive_class_WCAM_3 abstract "WCAM 3 is a class of locomotives used in the Indian Railways system. They are the third of the WCAM series. They were specifically designed for use by Central Railways in the Ghat section towards Pune. They usually work on Mumbai CST - Igatpuri - Itarsi or Mumbai CST - Pune section but not beyond that because of the unavailability of maintenance facilities.The WCAM 3 class locomotives are in service only in the Mumbai region’s Central Railway zone. The dual-voltage WCAM series locomotives haul intercity trains out of Mumbai DC suburban region on Central Railways which is on a 1500V DC overhead system, as opposed to other parts of India which have 25000 V AC overhead.With Central Railways progressively moving towards a complete changeover from DC to AC traction, trains leaving Lokmanya Tilak Terminus have started using pure AC engines [1] although WCAM engines still serve trains operating out of Lokmanya Tilak Terminus.These upgraded dual-traction models deliver 4600hp in DC mode and 5000hp in AC mode, and were jointly developed by RDSO and BHEL in 1997. Components are shared with the WCAG-1 locos (see below). Co-Co fabricated bogies (High-Adhesion -- shared with WCAG-1, WAG-7, WDG-2, etc.) with secondary suspension. Monocoque underframe. Air brakes are original equipment. They were originally manufactured under a BOLT (build-own-lease-transfer) contract with BHEL, and are probably still owned by BHEL rather than by IR.Monocoque underframe. Axle-hung, nose-suspended, force ventilated, taper roller bearings Speed control by tap changers in AC mode and resistance notching in DC mode. Motors can be placed in different series-parallel combinations. Auxiliaries from Elgi, S F India, Best, Gresham & Craven, etc. Static converter from ACEC for auxiliary supply.In DC mode, rheostatic braking by self-excitation of traction motors available until 17km/h. Elgi compressor, other auxiliaries from S F India. Rated for 105km/h in both DC and AC mode (sometimes AC mode rated speed is quoted at 110km/h). Traction motor configurations as in the WCAM-1/2 and WAM-4 (all 6 in series, 2S 3P, or all parallel -- the latter is the only one used under AC traction, enforced now by modifications to the locos).CR uses WCAM-3 locos on Mumbai-Pune and Mumbai-Igatpuri sections which have ghat portions as well as speed restrictions of about 100km/h. Freight rakes double-headed by WCAM-3 (upgraded models) have been sighted on the ghat sections. For excellent WCAM-3 sightings and regular double-header WDM-2 tanker trains, the Kurla-Vidyavihar section is ideal.MU operation possible with 3 (4?) units.Some WCAM-3 locos now [2004] are certified only for DC operation for various reasons, although it is possible they will be fixed and returned to full dual-traction service after repairs. As of [12/05], all WCAM-3 locos had been retrofitted with roof-mounted rheostatic braking grids.".
