Looking right at home in the tall timber of the Powder River Valley, Eccles Lumber Heisler #3 plods slowly eastward on the Sumpter Valley Railway, with a short work extra. Although #3 was technically owned by a logging operation, the Eccles Lumber people had a relationship with the Sumpter Valley, and this engine was sometimes involved in operations associated with maintenance of way on the main line. There are historic photographs of her being involved in such things as winter plow operations, alongside the SVRy's regular power. Unlike some other geared types that operated on the many logging operations that interchanged with the Sumpter Valley, this little Heisler could make 10-15 mph, and was a pretty useful engine. Doubtless, her utility and simplicity contributed rather heavily to her survival and eventual preservation on today's Sumpter Valley Railroad.
