The GS-1 was a 4-8-4 Northern type steam locomotive that served the Southern Pacific Railroad from 1930 to 1956. They were built by Baldwin Locomotive Works and were numbered 4400 through 4409. GS stands for "Golden State" or "General Service."

The GS-1 had all of the basic steam locomotive features; a silver smokebox with a mounted single headlight with a bell mounted just above it, teardrop classification lights, and whistles.

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

No GS-1 locomotives survive.
