The EMD GT46MAC is a freight-hauling diesel-electric locomotive with AC electric transmission built by General Motors Electro-Motive Division[1] in 1997–1998[2] for Indian Railways, where they are classed as WDG-4.[3] Thirteen were built by EMD as order #958647, and a further eight were exported in kit form and were assembled in India. The class entered service in 1999.[4] Further construction has been under license in India by the Diesel Locomotive Works (DLW); more than 60 additional locomotives have been built as of 2006.[3] They are numbered from #12000 upward. A similar type, the EMD GT46PAC, has also been produced for passenger service in India.
