In 1912, J.H. Chambers Lumber Company was a major investor when the line was reorganized as the OP&E. The OP&E built a 6 miles logging branch from Disston up Layng Creek in 1914, and in 1917, Chambers' Lumber company secured complete control of OP&E. As an economy move, Chambers built a gasoline-powered railbus to replace the daily passenger train.
