Skookum - Today

In 1955, Deep River Number 7 derailed and fell on her side while pulling a string of logging disconnects.  As Deep River was abandoning their logging operations, they left her there after taking up the rails.  She has been in the hands of railfans since 1956 and is currently owned by Rogan Coombs.  She currently resides at the Mt. Rainier Scenic Railroad's maintenance yard at Mineral, Washington awaiting restoration.  The following photos show her boiler, tender and frame.

A side shot clearly showing implementation of compounding.  High pressure steam entered the rear cylinders via a pipe dropping down from the steam dome.  From there low pressure steam exited the rear cylinders and entered the large front low pressure steam cylinders.  Photo by Jon Davis.

This is photo was taken while standing in front of the engine looking down the center to the back. The casting at the Bottom Center of the image is the "Center Pin Guide" for the lead truck. Right behind it are the Low Pressure Cylinders (aka Front Cylinders) of the engine. The piece of sheet metal on top of the cylinders is covering the Steam Exhaust port where a pipe would have attached and run to the smoke box to the Exhaust Nozzel.

Thanks and a tip of the hat to Curtis S. Ferrington for his explanation of this and the following two photos.  Photos by Jon Davis.

This and the next photo were basically taken from while standing in the same spot; On the engines left side just ahead on the High Pressure Cylinders (aka Rear Cylinders) and looking down at the Articulation Joint (pivot point) between the Front and Rear Engine beds. The large pin at the center of the photos is the Hinge Pin that the units actually swing, and slide vertically on. The large pipe fitting just above the pin is the Steam Exhaust port from the High Pressure cylinders. A pipe runs from it to supply the Low Pressure cylinders up front. The pipe was centered to minimize movement in the pivoting/sliding pipe joints as the engine articulated.
