For those interested in Standard Gauge Shays, the PFC shays ran on the WI&M in North Idaho, hauling White Pine out of the woods to the mill at Potlatch, ID.
Potlatch Forest Company #102
#106
#107
#200, near Bovil, Idaho
107 and 200 had the later “White Pine Route” logo on their tenders. Photos take sometime in the 1930’s.
Weyerhauser Timber Company #2
Weyerhauser Timber Company #5
Washington Idaho & Montana #102, probably the same locomotive as Potlatch Forest Company 102
The locomotive had an unusual if not unique employment of cylinders. The lead two were of the piston valve type, with the rear-most cylinder being of the slide valve type. The chest cover of that rear cylinder faced perpendicular to and away from the boiler.
