The '''Indian locomotive class WDG-4 (EMD GT46MAC)''' is a [[freight]]-hauling [[diesel-electric locomotive]] with AC electric transmission designed by [[Electro-Motive Diesel|General Motors Electro-Motive Diesel]]<ref>{{cite web |url=http://www.gmemd.com/en/locomotive/international/gt46mac/ |title=GM EMD: GT46MAC |access-date=2006-11-19

Thirteen were built by EMD as order #958647, and a further eight were exported in kit form and assembled in India. The class entered service in 1999.

Further construction has been under license in India by the [[Banaras Locomotive Works|Banaras Locomotive Works (BLW)]]; more than 60 additional locomotives have been built {{As of|2006|lc=on}}. They are numbered from #12001 upward. A similar type, the [[EMD GT46PAC]], has also been produced for passenger service in India.

{{As of|2007}}, EMD and DLW have begun building GT46Ace's using [[IGBT]] technology to replace the older [[gate turn-off thyristor]] technology. Newer editions with {{convert|4500|hp|kW|abbr=on}} have been produced. Over 1,000 WDG-4 locomotives are currently in operation.
