The Southern Pacific was an American Class I railroad network that existed from 1865 to 1996 and operated largely in the Western United States. The system was operated by various companies under the names Southern Pacific Railroad, Southern Pacific Company and Southern Pacific Transportation Company.
The St. Louis Southwestern Railway Company, known by its nickname of "The Cotton Belt Route" or simply "Cotton Belt", is a former Class I railroad that operated between St. Louis, Missouri, and various points in the U.S. states of Arkansas, Tennessee, Louisiana, and Texas from 1891 to 1980, when the system added the Rock Island's Golden State Route and operations in Kansas, Oklahoma, and New Mexico. The Cotton Belt operated as a Southern Pacific subsidiary from 1932 until 1992, when its operation was assumed by Southern Pacific Transportation Company.
The Southern Pacific GS-4 is a class of streamlined 4-8-4 "Northern" type steam locomotive operated by the Southern Pacific Railroad (SP) from 1941 to 1958. A total of twenty-eight were built by the Lima Locomotive Works, numbered 4430 through 4457. GS stands for "Golden State" or "General Service."
Southern Pacific 4449, also known as the Daylight, is the only surviving example of Southern Pacific Railroad's "GS-4" class of 4-8-4 "Northern" type steam locomotives and one of only two GS-class locomotives surviving, the other being "GS-6" 4460 at the National Museum of Transportation in St. Louis, Missouri. GS is an abbreviation of "General Service" or "Golden State," a nickname for California.
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".
The GS-5 was a class of streamlined 4-8-4 "Northern" type steam locomotive operated by the Southern Pacific Railroad (SP) from 1942 to 1958. A total of two were built by the Lima Locomotive Works, numbered 4458 and 4459. GS stands for "Golden State" or "General Service."
The GS-3 was a class of streamlined 4-8-4 "Northern" type steam locomotive operated by the Southern Pacific Railroad (SP) from 1938 to 1957. A total of fourteen were built by the Lima Locomotive Works, numbered 4416 through 4429. GS stands for "Golden State" or "General Service."
The GS-2 was a class of streamlined 4-8-4 "Northern" type steam locomotive operated by the Southern Pacific Railroad (SP) from 1937 to 1958. A total of six were built by the Lima Locomotive Works, numbered 4410 through 4415. GS stands for "Golden State" or "General Service."
The GS-1 was a class of conventional 4-8-4 "Northern" type steam locomotive operated by the Southern Pacific Railroad (SP) and its Texas subsidiary the Texas and New Orleans Railroad (T&NO) from 1930 to 1956. A total of fourteen were built by the Baldwin Locomotive Works, numbered 4400 through 4409 by SP and 700 through 703 by T&NO. GS stands for "Golden State" or "General Service."
Southern Pacific 4460 is the only surviving class "GS-6" steam locomotive, together with "GS-4" class Southern Pacific 4449, which is operational in excursion service. The GS-6 is a semi-streamlined 4-8-4 "Northern" type steam locomotive. GS stands for "Golden State" or "General Service". The locomotive was built by the Lima Locomotive Works (LLW) for the Southern Pacific Railroad (SP) in 1943. The GS-6 lacked side skirting and red and orange "Daylight" paint found on previous locomotives of the GS class and were painted black and silver instead. The War Production Board controlled locomotive manufacturers during World War II and had turned down Southern Pacific's order of fourteen new Daylight locomotives in 1942. Southern Pacific re-designed the new fleet based on the older GS-2s, only with 260 psi instead of 250 psi, an all-weather cab, and a new GS-4 style tender. The design was finally approved, but the War Production Board reassigned four to the smaller and power-starved Western Pacific Railroad. Their smaller size when compared to previous GS class locomotives and the fact that they were built during World War II earned them the nicknames "War Babies".
El Gobernador was an American 4-10-0 steam locomotive built by Central Pacific Railroad at the railroad's Sacramento, California shops. It was the last of Central Pacific's locomotives to receive an official name and was also the only locomotive of this wheel arrangement to operate on United States rails. At the time it was built, El Gobernador was the largest railroad locomotive ever built. Its name is reminiscent of the railroad's first locomotive, Gov. Stanford, as El Gobernador is Spanish for The Governor. This locomotive is a Mastodon type. Confusingly, this was the unofficial name for an earlier engine, "Mastodon" No. 229, the first successful 4-8-0 ever built. Both engines looked nearly identical, except that El Gobernador was longer and had an additional pair of drivers.
Southern Pacific 2472 is a P-8 Class 4-6-2 heavy "Pacific" type steam locomotive built by the Baldwin Locomotive Works for Southern Pacific Railroad (SP) in 1921. No. 2472 is one of three surviving Southern Pacific P-8 class 4-6-2 Pacific locomotives, the other two bring Nos. 2467 and 2479. The 4-6-2 designation means it has four leading wheels, six driving wheels, and two trailing wheels. The locomotive was used by the Southern Pacific Railroad to haul passenger trains until being retired in 1957. The locomotive was then donated to San Mateo County and placed on static display at the San Mateo County Fairgrounds. After being restored to operational condition in the early 1990s, the locomotive would pull excursion trains on the Niles Canyon Railway until being retired in 2015. The No. 2472 was then moved to the Northwest Pacific Railroad, where it is as of 2023, undergoing its Federal Railroad Administration (FRA) mandated 1,472 day inspection and overhaul.
Mastodon was the unofficial name of the Central Pacific Railroad's number 229, the world's first successful 4-8-0 steam locomotive.
T. D. Judah was the name of a 4-2-2 steam locomotive owned by the Central Pacific Railroad. It was named in honor of the railroad's first chief engineer, Theodore Dehone Judah, who had championed and surveyed a passable route over the Sierra Nevada for the Transcontinental Railroad.
