The Oregon, Pacific & Eastern Railway Company incorporated in 1912, purchased the physical assets of the O&SE two years later, and shortened their total trackage to operate  from an interchange yard with the Southern Pacific Railroad at Cottage Grove, east to a 528' x 156' turnaround loop at Culp Creek.
