Southern Pacific GP9 Nos. 3775 and 3836 sit at the small locomotive facility at Tracy Yard in tracy, California, on March 3, 1987. Colorful No. 3775 is decked out in the SPSF (Shouldn’t Paint So Fast) Southern Pacific Santa Fe colors nicknamed “Kodachrome” for the famous Kodak slide film used back then. At least the unit still has its full SP light package!
