"The following historical and technical information is derived from the book
"Southern Pacific Daylight Locomotives" by Robert J. Church

With the heavy demands of World War II traffic, the Southern Pacific needed more locomotives and submitted an order to the war production board including 16 more GS-4 4-8-4's. The initial reaction of the board was that more passenger locomotives were not necessary, so the order was initially rejected. The Southern Pacific then requested an order for copies of the smaller GS-2's, and referring to the "GS" designation as "General Service" for both passenger and freight use. This order was approved for the new GS-6 designated locomotives, though six engines were re-allocated to the WP in the form of GS-64's. All were oil burners, were equipped with trailing truck boosters, Worthington feedwater heaters, and Elesco superheaters. The tenders were nearly identical to those from the GS-4's, having 6000 gallons oil and 23,300 gallons water capacity. Initially these engines were used on the Northern District powering heavyweight passenger trains such as the West Coast, Cascade, etc, then were later assigned to the Sacramento and San Joaquin Valleys where they served until they were retired.
