Data from "Central Provinces Railways (India)", Locomotive Magazine, Volume XXII [22] (15 April 1916), p. 68.
LM reported that the CPR ran through "very fertile country largely devoted to growing cotton and grain" from Murtajapur's station on the Nagpur branch of the Great Indian Peninsula Railway. Skinny-gauge lines extended in opposite directions from Murtajapur in central India to "Ellichpur" (later -- Achalpur) 48 miles/77 km to the northeast, and Murtajapur to "Yeotmal" (later Yavatmal) which lay 70 miles/113 km to the southeast. Yavatmal was a cotton headquarters that lay at 1,500 ft (457 m) above sea level.
The long-boilered 8-coupled tank used a Belpaire firebox and outside constant-lead radial valve gear. It was small even for the 762-mm gauge, but its trailing load came to less than 50 tons as three carriages weighed 9-11 tons (9.9-12.1 short tons).
Other Internet images show that this quartet represented a standard Hudswell design with locomotives operating both in industrial settings and in other non-British countries such as Iraq.
