Broadway Limited BLI#7615 4-8-4 GS-4 #4442, In-Service, As-Delivered, Daylight Paint, SOUND/DC/DCC Southern Pacific

The Southern Pacific GS-4 locomotives were a class of 4-8-4 "Northern" type steam locomotives operated by the Southern Pacific from 1941 to 1958. The SP owned a total of 28 GS-4 engines, numbered 4430 through 4457. The GS-4's were quite similar to the SP GS-3 Northerns, except with the GS-4, the SP introduced a dual-headlight casing, with the top light being a Mars light, and also the GS-4 had an all-weather cab.

The GS-4 locomotives were designed and primarily used for passenger service. They were capable of reaching high speeds, and wore the colorful Daylight paint scheme to match Southern Pacific Daylight passenger cars. Some of the engines were painted black during WWII, and most of them were eventually painted black later in life.
