Little History:

The GS-6 is a class of semi-streamlined 4-8-4 Northern type steam locomotive operated by the Southern Pacific Railroad (SP) from 1943 to 1958 and the Western Pacific Railroad (WP) from 1943 to 1953. A total of sixteen were built by the Lima Locomotive Works, numbered 4460 through 4469 by SP and 481 through 486 by WP. GS stands for Golden State or General Service. One GS-6 survives today, Southern Pacific 4460 (the first one to be built), which pulled the final movement of steam on the Southern Pacific Railroad in 1958. It was donated to the National Museum of Transportation in St. Louis, Missouri, where it has remained ever since. Also, the tender of Western Pacific GS-6 No. 484, which was used in its final years as a water and fuel tank for a rotary snowplow, is stored at the Western Pacific Railroad Museum in Portola, California.
