Data from "Two Interesting Kitson Locomotives," The Locomotive Magazine, Vol XIII (15 January 1907), pp. 14. Boiler pressure is an estimate.
These were express engines on a 1,112-mile railway that in a few years would be taken over by the Great Indian Peninsula Railway. The large cab with extended eave gave the design an American look, notwithstanding the inside cylinders, clean boiler with polished brass dome, and splashers over both driving axles. All of the engines had names commemorating cities served by the railway.
