Among the many logging roads that served timber harvesting in the Northwest was this Lewis County railroad, which laid its 56 lb/yard (28 kg/metre) rail in the woods near Bunker, Wash. A wood-burning logging Prairie from Baldwin was a frequent choice for such lines.
Harold "Harry" J. Syverson was the company's founder in 1912. According to contemporary news reports, the HLC controlled 100 million feet of timber and began operations in February 1913. Syverson resigned a year later to run another company. The HLC was sold to Bunker Creek Logging Company in March 1923 after it had logged out tmost
This long-stroke, oil-burning logging Prairie design served many different lumber companies. In this instance, the HLC was based in Haynesville, La and was part of Frank E Sheldon's extensive lumber empire. (Sheldon had helped lay out the route through the Canadian Pacific's Kicking Horse Pass and Selkirk Pass.) HLC logged yellow pine timber.
Similar to several other Baldwin logging Prairies with saddle tanks, the 5 was fired by the less-usual oil fuel. The specs guaranteed that the engine would pull 70 short tons of cars and lading up a straight 7% (370 ft/mile or 70 metres/km), "assuming frictional resistance of not more than 10 lb per ton [4.9 kg/tonne]." The Washington State railroad also featured curves of 35 degrees (166 foot/50.6 metre radii).
Another note reflecting earlier problems reads: "Equalizing beam between back drivers and engine truck broke. Strengthen them. Provide proper support at back to avoid this."
When the Hammond closed down operations and dismantled its road in 1937, the 7 had already moved on to Interstate Logging Company as their 6. Interstate sold the 6 in November 1936 to Consolidated Timber.
