Postcard photo of 4 new GS-3 locomotives for Southern Pacific's "Coast Daylight" train. The train made its debut in 1937 with GS-2 locomotives which were replaced in late 1937 or early 1938 with the newer GS-3s.
Date
Late 1937 to early 1938. The train had GS-2 locomotives when it began its route in 1937. In late 1937, the GS-3 locomotives were built for use with this line. The next "step" for steam power would be the GS-4, but they didn't begin building them until 1941. DOPS cards (letters in stamp box) were produced from 1925 to 1942.
DOPS for Southern Pacific (see "SP 1003" notation at front lower right).
