I'm having serious difficulty determining the notability of these two rebuilt locomotives as individual units. The referencing shows that the exist, but does not show that the pass WP:GNG. I feel a more suitable route is to add the details to EMD GP9 rather than this article. I believe that this, were it to be accepted into mainspace, is the wrong side of the notability border and would be vulnerable to an immediate deletion process.

This draft's references do not show that the subject qualifies for a Wikipedia article. In summary, the draft needs multiple published sources that are:

in-depth (not just passing mentions about the subject)
reliable
secondary
independent of the subject

The EMD GP9E and GP9R are rebuilds from EMD GP9 diesel locomotives that were built by General-Motors Electro-Motive Division for the St. Louis Southwestern Railway (also known as the "Cotton Belt Route") and the Southern Pacific Transportation Company.^[1]^[2]^[3]

History

Beginning in 1970 with SP GP9 #3424, all of the pre-existing EMD GP9 diesel locomotives that were on the St. Louis Southwestern Railway (also known as the "Cotton Belt Route") and Southern Pacific's roster were rebuilt into GP9E's and GP9R's with the number series beginning at #3300.^[1]^[2]^[3]

Because of the internal differences of the three 'Phases', different 'rebuild' schemes were required, which meant that they were placed into different number series. As well some got Farr air filter boxes behind the cab of the units.^[1]

As the rebuilds had came and went, alongside the un-rebuilt units, no numbers were reused from the Southern Pacific's 1965 renumbering scheme.^[1]

The Southern Pacific Transportation Company began rebuilding their units in 1970, while the St. Louis Southwestern Railway (also known as the "Cotton Belt Route") began rebuilding their units in 1974.^[1]

SP's Paint scheme variants

Nine of Southern Pacific's GP9E/GP9R locomotives were painted into the Southern Pacific's "Kodachrome" livery of the Failed merger between Southern Pacific and Santa Fe, these units were GP9E/R locomotives #2873, #3370, #3735, #3739, #3775, #3778, #3784, #3792 and #3846.^[1]

Preservation

Out of all the 283 units that were rebuilt, six EMD GP9R locomotives have survived into preservation:

Southern Pacific GP9R #2873 (formerly Texas and New Orleans GP9 #443, SP #3798 and SP #3565) is currently preserved at the Western Pacific Railroad Museum (WPRM), it was donated to the WPRM in 1992 and currently still resides there to this day.^[4]^[5]
Southern Pacific GP9R #3189 (formerly, SP #5623 and #3005) is now operational at the Niles Canyon Railway (NCRy) as Southern Pacific GP9 #5623.^[6]
Southern Pacific GP9R #3194 (formerly Texas and New Orleans GP9 #281, SP #5895 and #3001) which had worked on the SP's Peninsula Commute from 1960/61 to 1985 before being retired in 1998 and donated to Golden Gate Railroad Museum (GGRM) that same year.^[7]
Southern Pacific GP9R #3709 (formerly SP GP9 #5873) is at the Pacific Southwest Railway Museum Association in Campo, California.^[8]^[9]
Southern Pacific GP9R #3769 (formerly SP GP9 #5733 and #3574) is currently on static display at the Utah State Railroad Museum in Ogden, Utah.^[10]
Southern Pacific GP9R #3873 (formerly SSW GP9 #3873, SSW 3651, SSW 830) is currently at the Pacific Southwest Railway Museum Association in Campo, California.^[11]^[12]

Southern Pacific #5623 at the Niles Canyon Railway in 2006.
Southern Pacific GP9R #2873 at the Western Pacific Railroad Museum (WPRM) in the Southern Pacific's "Kodachrome" livery.
Southern Pacific GP9R #3194 at the Golden Gate Railroad Museum (GGRM)
