GS-4 Southern Pacific Wartime Black "Lines"

About the Southern Pacific GS-4 in Wartime Black:

Originally delivered in “Daylight” colors, many GS-4's were repainted by the SP in wartime black to reduce paint maintenance (and make them less visible in the event of air raids), with “Southern Pacific Lines” lettering and with full skirting. These locomotives represent the first group of GS-4 locomotives delivered in April and May of 1941 which were assigned to the Coast and Los Angeles Divisions. They were used to pull the “Morning Daylight” and other Southern Pacific trains such as the “Coast Mail”, but were also used in freight service.
