The Indian locomotive class WDG-6G (GE ES57ACi)[1] is a class of diesel–electric locomotive used by the Indian Railways for freight duty. The locomotive is a higher power variant of the WDG-4G locomotive which was also designed by General Electric. The design platform is based on the GE Evolution Series and features a 4-stroke16-cylinder fully turbocharged engine which delivers around 6,000 hp (4,500 kW), making it the most powerful diesel locomotive of IR (the second being its WDG-5 predecessor).[2]
Two units were produced by Wabtec's plant in Pennsylvania, United States, and delivered to India in 2019.[3] Initially, a few will be made in USA. Under the 'Make in India' initiative of Indian Government, GE will manufacture all remaining units at its factory in Marhowra, Bihar. GE has also built maintenance sheds at Roza in UP and Gandhidham in Gujarat.
