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

[edit]

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

[edit]
SP GP9R #3792 in the Southern Pacific's "Kodachrome" livery.

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

[edit]

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