WCAM-1 was purely a DC Electric Loco just like WCM-1 to 5s. I wish that those giant WCMs would have hauled trains between Bombay Central (Mumbai BCT) and Baroda as an Off link, especially for the Bombay Rajdhani Exp :-D

PS: Valsad WCAM-1s have hauled the BCT Raj as Off links when RTM WDMs were unavailable for the BCT-BRC Run :)
