Many early-day logging companies around the world used a curious looking piece of equipment called a “Walking Dudley,” described as a power car on rails.

The machine was said to have been invented by longtime-logger Sol Simpson of Washington State. In some areas it was used to pull itself or “walk” up an incline or down hills by means of a big cable wrapped several times around a large wheel that was powered by a steam engine. 

In the late 1890’s Siskiyou and Klamath County loggers along the Klamath River used their own version of the machine built by the Willamette Iron and Steel Company of Portland.  This Walking Dudley consisted of a vertical steam engine mounted on a flat car that moved by means of a winch and cable.

The Walking Dudley helped move logs down a 2,650-foot chute into the Klamath River by straddling the log chute at the top. The Walking Dudley would give reluctant logs a nudge to start their journey down the long chute and into the river to float to the sawmill -- a spectacular sight to see..
