my ESPEE MODELERS ARCHIVE
California's Railroad to the U.S. 1861 - 1996
Southern Pacific SD40M-2
8574 - 8706
133 units delivered
In 1993, SP contracted with Morrison Knudsen to supply 133 SD40M-2's, as part of the contract, SP was to supply no carbodies or shells. This sparked a frantic search for 133 six axle locos suitable for rebuilding. The search turned up 30 SD40's, 97 SD45's and 6 SDP45's. Due to another kitbash happening at MK at the time, 10 of the rebuilt SD45's received GP40 rear hoods and radiators. This resulted in 4 distinct versions, although all classified SD40M-2.
As far as we (modelers) are concerned, the SD40's and SDP45's retained their basic carbody shape. The SD45's came in 2 flavors, most also retained their carbody shape, with the exception of the 10 numbers listed below, these and the SDP45's, would represent the most interesting models to kitbash.
If you are interested in modeling any of these, then I cannot recommend highly enough, the Diesel Era article listed below, and of course a photo of the unit you are going to kitbash.
As best as I can figure out, with the References I have available, the units listed below are correct.
As built configuration:
In service modifications:
Although most SP modelers refer to the exCR (EL) units as SDP45's, (probably because SP had an order of SDP45's), I believe EMD called these SD45M's. EL ordered these for run-through freight service, requiring the longer frame for a 4000 gallon fuel tank, they never had a steam generator.
Trivia (from Mike Clark), SP #8690 exBN #6567 was the last SD45 built by EMD.
