Data from "Six Wheels Coupled Goods Engine: Eastern Bengal State Railway", Railway Engineer, Volume XX [20], No 4 (April 1899), pp.110-111. Works numbers were 1659-1678 in 1899.
RE's account credits the design of this very English six-coupled freight engine designed by A S Jameson under the superintendence of the consulting engineer, Sir Alexander Rendel. A key feature was its sharing of major components with the 4-4-0s described in Locobase 16067. These included "cylinders, motions, crank and straight axles, boiler and its mountings, and the tenders ..."
Locobase notes the sloping grate and the unsurprising appearance. Details noted included fitting the whistles and steam gauge cocks to the safety valve fitting "in order to reduce the number of holes cut into the back plate" and the "great care ...taken to have the wearing surfaces as large as possible."
The result, RE said, was that the class was "giving very general satisfaction ...hauling heavy loads at a good rate of speed on a low consumption of native coal."
Data from "Narrow-Gauge Locomotive, Indian State Railways", Engineer, Volume 77 (22 June 1894), pp. 544, 550.
Small tank locomotives with outside cylinders, inside valves. The pair was sent to the Kauni-Dharila Section of the EBR.
