SP's livery variants

SPSF "Kodachrome" livery

Southern Pacific painted units which were #7303, #7310, #7319, #7357, #7361 and #7384 into the Southern Pacific's "Kodachrome" livery of the proposed and failed merger between Southern Pacific and Santa Fe.

SP's "Daylight" livery

SP #7340 in the SP's "Daylight" livery

In 1980, one unit #7340 was painted into the Southern Pacific's "Daylight" livery, predominantly sported the Daylight Orange colours, the front of the nose, and the rear of the long hood were Red, more likely to be SP Scarlet than Daylight Red. A Standard red wing with 'feathers' appeared on the right-hand side of the nose, but the left-hand side had a solid red wing.

The lettering and cab side number on the left-hand side was shown as red, but on the right-hand side, the lettering was shown as white, on both sides the lettering was stacked, the word "Pacific" under the word "Southern", rather than all in one line. A white Gothic SP was applied to the front of the nose.
