Data from "New Passenger Locomotives, SMR ", The Locomotive Magazine, Vol XIII (15 March 1907), p. 45. Boiler pressure is an estimate.
This set of Ten-wheelers had Belpaire fireboxes, radial valve gear outside, a capped stack, dome over the leading coupled axle, inside bearings on the bogie, and a long cab roof. Their main service ran from Poona to the South of India through Bangalore.
