The Southern Pacific Class P-8 was a class of 4-6-2 "Pacific" type steam locomotives that were built by the Baldwin Locomotive Works for the Southern Pacific Transportation Company in 1921.

[1][2] In all, a total of 15 locomotives of what had become the Southern Pacific Class P-8 were ever constructed by the Baldwin Locomotive Works in 1921 and they were all numbered as 2461-2475.

[1][2] They were designed to be used on the Southern Pacific specifically for the Overland Route from Ogden, Utah, to Oakland, California.

[1] The P-8 locomotives had thrived until the larger, more powerful Mt-class of 4-8-2s were delivered in the late 1920s.

[1] Withdrawal of the class commenced in 1958, and all but two were scrapped.
