No. 4412 was one of six GS-2's built for the SP, essentially streamlined and improved versions of their GS-1 engines which were built by Baldwin.
(Off in the distance the mournful cry of the air horn on GS-2 #4412 broke the silence of the quiet Pajaro Valley.)
No. 4412 was retired from the Southern Pacific in 1956 and all the GS-2s were also retired later that year, when the diesels took over; No. 4412 was sold for scrap along with its five sisters. None of the GS-2's have been preserved.
- No. 4412 was featured in films such as "The Narrow Margin" (1952), the opening of "Adventures of Superman" (1952), and even in the 1986 film "Tough Guys" in 2 portraits.
- The engine was once repainted from its "Daylight" paint scheme to its postwar black and silver scheme.
- No. 4412 once hauled a special passenger train named the "Daylight Limited" on its demonstration run near Aromas, California in 1937.
