Placed on the line immediately after Polson Logging engine 101 described in Locobase 12764, this Mikado had a smaller tender, but was otherwise identical. It went to nearby Kerriston, Wash. Its flangeless drivers (on 2nd and 3rd axles) contributed to its being able to negotiate 30-deg curves.
2's subsequent career had several more stops than the 101. It was sold to the NorthWest Lumber Company then in 1929 to Polson. Like the 101, the 2 was kept in service when Rayonier Corporation took over Polson in 1948. In 1963, the 2 moved 2/3s of the way across the country to operate in tourist service on the Grand Travers Northern (Michigan), then on the 4. 1/2 -mile Cadillac & Lake City. Then sold to Kettle Moraine, the 2 eventually was donated to the Illinois Railway Museum.
