Southern Pacific Class GS-1

Southern Pacific No. 4405 is an example of a Southern Pacific class GS-1.

The Southern Pacific class GS-1 was a class of fourteen 4-8-4 Northern-type steam locomotives that served the Southern Pacific Railroad and its Texas subsidiary the Texas and New Orleans Railroad from 1930 to 1956.

A total of fourteen were built by Baldwin Locomotive Works in May–July 1930. The Southern Pacific received ten locomotives which were numbered 4400 through 4409, while the Texas and New Orleans Railroad received four locomotives which were numbered 700 through 703; these locomotives were later renumbered and served on the Southern Pacific as the second 4400, 4403, 4404 and 4407. The GS-1s were also the only non-streamlined member of the Southern Pacific GS-class locomotives.

They were assigned to various passenger trains throughout the SP system, and ended their careers on the San Jose-San Francisco commutes. They also hauled freight trains on occasion.

No GS-1 locomotives survive today.
