The EMD SD9E was a rebuild from EMD SD9 diesel locomotives that were built by General-Motors Electro-Motive Division for the Southern Pacific Transportation Company.^[1]

History

The Southern Pacific Transportation Company began ordering 150 EMD SD9 units from General-Motors Electro-Motive Division where they originally classified their units as DF-120, DF-121, DF-122, DF-123, DF-124 and DF-125, with the first 105 units being numbered as 5340–5444, and the other 45 units being numbered as 5449–5493.^[2] The Southern Pacific Railroad had 53 of their units #5340–5391 fitted with the Vapor-Clarkson Steam Boiler OK4625 type steam generator upon when those 53 units were ordered from General-Motors Electro-Motive Division.^[2]

Then, in 1965, Southern Pacific Railroad had reclassified their units as EF618-1, EF618-2, EF618-3, EF618-4 and EF618-5, as well as renumbering them as 3800-3966.^[2] Then, between August 1970 and March 1980, the Southern Pacific Transportation Company had rebuilt 144 of their units under the General Rehabilitation and Improvement Program (G.R.I.P) and renumbered 142 of their rebuilt units as 4300-4441 and two additional rebuilt units being renumbered as 4450 and 4451, as well as reclassifying their 142 units as EF618E-1 and classified their two units #4450 and #4451 as EF618E-2, which had left six other SD9 locomotives un-rebuilt.^[2][3]
