Located in the eastern plateau of the Deccan in central Indian, the NGSR developed coal traffic from its Singareni coal mine that by 1911 was a profitable enterprise. This trio of suburban locomotives supported the Hyderabadi commuter service. They were virtually identical to the Burmese engines (Locobase 7502) supplied three years earlier by the same builder.
