Data from DeGolyer, Vol 60, pp. 376. Works numbers were 52719-52721 in December 1919, 52810-52811 in January 1920.
The layout of this small tank seems to have placed maneuverability in tight places over most other qualities. The curves within this big plant were as bowed as 30 degrees (radii of 193 ft/59 metres) and gradients could be as steep as 2%. Compared to other six-coupled engines on such a narrow gauge, this design was in the upper half in power and weight.
The rectangular side tanks held 420 US gallons (1,590 litres) each and the rear tank another 360 US gallons (1,363 litres).
The plant, which took three years to build and opened on 18 January 1923, featured twelve carbonization retorts that processed 240 tons of wood per day into two tar products: a soluble tar used as a disinfectant and a settled tar used in wood preservation.. Other facilities included a distillation plant to recover and manufacture by-products and a 60-ton capacity charcoal blast furnace that turned out charcoal pig iron.
