WDG4 class locomotive in Delhi Junction

The Indian locomotive class WDG-4 (EMD GT46MAC) is a freight-hauling diesel-electric locomotive with AC electric transmission designed by General Motors Electro-Motive Diesel[1] in 1997–1998 for Indian Railways, where they are classed as WDG-4. 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 (BLW); more than 60 additional locomotives have been built as of 2006. 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 4,500 hp (3,400 kW) have been produced. Over 1,000 WDG-4 locomotives are currently in operation.
