The Colorful Southern Pacific
Colorful isn’t an adjective associated with the Southern Pacific since the 1950’s, but there was a short period of time some 30 years ago when a handful of SP locomotives were quite colorful.
In the late 1970’s / early 1980’s, the SP flirted with the idea of changing its locomotive colors from scarlet & lark gray to a variation of the classic Daylight colors, red, orange and black.
These experimental paint schemes were applied to SD40E 7342, SD45E 7399, and caboose #1 in the 1981-1982 time frame.
But the very first application of these colors to freight power took place a few years prior, when the SP took delivery of 4 TE70-4S locomotives from Morrison-Knudsen in early 1978.
These 4 units had been re-built from U25B’s that had been retired from the SP. The re-build program was less-than-successful, and no others were ordered by the SP.
