Class Details by Steve Llanso of Sweat House Media

Class unknown (Locobase 14461)

Data from "Manufactures--Supplies: Cars and Locomotives", The Railway Age, Vol 28 (1 September 1899), p. 654. See also "Malvern Roundhouse History,"

The LR&HS was chartered as a narrow-gauge road and began construction in 1875 in Malvern, Ark and eventually linked Malvern to Butterfield Junction and beyond to Hot Springs. Not long after the completion in 1887 of the five-stall Malvern roundhouse, the railroad decided to convert to the standard gauge. This required modifications to the stalls and turntable of the roundhouse. The wider railroad opened on 16 October 1889.
