Long Bell Lumber Company 2-6-6-2 Locomotives of the USA


Class Details by Steve Llanso of Sweat House Media

Class 1000 (Locobase 4056)

Data from http://loggingmallets.railfan.net, supplemented by DeGolyer, Vol . 71, p. 288+. Works numbers were 57597-57598 in January 1924.

The Baldwin specs showed that this rather large articulated was expected to negotiate curves of 40 degrees (146 foot/44.5 metre radii), and conquering grades of 6% and 7%. 8" (203 mm) piston valves served the HP cylinders, 12" (305 mm) piston valves directed the HP exhaust steam to the LP cylinders.

These engines ran on Long Bell property out of Ryderwood, Wash., for their entire working lives. Both were scrapped in the mid-50s.
