A January 1936 inventory of the line notes: “Concrete sub-station. Three family operators’ cottage. Poor condition.”
Authorization for Expenditure (AFE) E-2892, dated December 5, 1944, authorized the retirement of all eight substations on the Oregon Electric network — including Pirtle — in preparation for the total abandonment of electric traction on July 10, 1945.
AFE #2955, dated January 18, 1946, allows for the sale of the substation operators’ cottage.
The shell of the substation still exists today, see the entry in the “Remnants” section of the site: Pirtle Substation (Oregon Electric)
