One of several standard designs for the Indian metre gauge. Not an attractive design with its cylindrical boiler mounted on a pedestal, the steam pipes to the cylinders masked in rectangular housings, the firebox entirely above the running board. But beauty is as beauty does ...
Dr. Jonathan Smith of Iowa State ([] ) offers slightly different dimensions for this class, including an 18 sq ft grate
