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".
When the Southern Pacific Railroad placed an order for fourteen new "Daylight" locomotives from Lima in 1943, World War II was raging and the War Production Board restricted what types of locomotives could be manufactured. SP's order was turned down, with the government deciding that streamlined passenger engines were not necessary to move wartime traffic. Southern Pacific re-designed the engines for general service and the order was finally approved. The smaller and power-starved Western Pacific Railroad was also looking for locomotives at the time and had first requested diesels, then a different style of steam locomotive. The War Production Board instead diverted six GS-6s (reportedly to have been numbered SP 4470-4475) to the WP. SP patented items were not included and the WP requested Franklin boosters be installed, making them slightly different from the SP engines upon delivery. The WP referred to them as GS-64-77s.
The GS-6 looked similar to the GS-2, with a silver smokebox with a cone-shaped single headlight casing and 73-inch (1.854 m) drivers. Like all GS engines, they had teardrop classification lights and an air horn to supplement their whistle. They retained the skyline casing on the top of the boiler but did not have the side skirting of previous GS locomotives. Southern Pacific's GS-6s also lacked the orange and red "Daylight" paint scheme that the previous GS engines so famously wore. Western Pacific's GS-6s received "elephant ears" similar to that of the Union Pacific Railroad's 4-8-4 locomotives.
The GS-6s were used by Southern Pacific for the San Joaquin Daylight , as well as San Jose-San Francisco Peninsula Commute service and freight service.
The Western Pacific used its GS-6s (GS-64s as WP classified them) on passenger trains and in freight service as well. They acquired a different look from their SP sisters when the WP applied the "elephant ear" style smoke deflectors to all six locomotives. When the Western Pacific dieselized in 1953 they sold three GS-64 engines (WP 481, 484, and 485) to Southern Pacific for spare parts, but kept the tenders and converted them to steam generators for rotary snowplows.
One GS-6 locomotive survives today, Southern Pacific 4460 (the first one to be built), which pulled the final movement of steam of 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.
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.
Under the Whyte notation for the classification of steam locomotives, 4-8-4 represents the wheel arrangement of four leading wheels on two axles, eight powered and coupled driving wheels on four axles and four trailing wheels on two axles. The type was first used by the Northern Pacific Railway, and initially named the Northern Pacific, but railfans and railroad employees have shortened the name since its introduction. It is most-commonly known as a Northern.
A streamliner is a vehicle incorporating streamlining in a shape providing reduced air resistance. The term is applied to high-speed railway trainsets of the 1930s to 1950s, and to their successor "bullet trains". Less commonly, the term is applied to fully faired upright and recumbent bicycles. As part of the Streamline Moderne trend, the term was applied to passenger cars, trucks, and other types of light-, medium-, or heavy-duty vehicles, but now vehicle streamlining is so prevalent that it is not an outstanding characteristic. In land speed racing, it is a term applied to the long, slender, custom built, high-speed vehicles with enclosed wheels.
A rotary snowplow or rotary snowplough is a piece of railroad snow removal equipment with a large circular set of blades on its front end that rotate to cut through the snow on the track ahead of it. The precursor to the rotary snowplow was the wedge snowplow.
The Pennsylvania Railroad (PRR) K4 4-6-2 "Pacific" was its premier passenger-hauling steam locomotive from 1914 through the end of steam on the PRR in 1957.
The Coast Daylight, originally known as the Daylight Limited, was a passenger train on the Southern Pacific Railroad (SP) between Los Angeles and San Francisco, California, via SP's Coast Line. It was advertised as the "most beautiful passenger train in the world," carrying a particular red, orange, and black color scheme. The train operated from 1937 until 1974, being retained by Amtrak in 1971. Amtrak merged it with the Coast Starlight in 1974.
The Southern Pacific GS-4 is a class of semi-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-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".
The Western Pacific Railroad Museum (WPRM) in Portola, California, known as the Portola Railroad Museum until January 1, 2006, is a heritage railroad and archives that preserves and operates historic American railroad equipment and preserves documents, photos and information. The museum's mission is to preserve the history of the Western Pacific Railroad and is operated by the Feather River Rail Society, founded in 1983. It is located at a former Western Pacific locomotive facility, adjacent to the Union Pacific's former Western Pacific mainline through the Feather River Canyon.
The Norfolk and Western J class was a class of fourteen 4-8-4 "Northern" streamlined steam locomotives built by the Norfolk and Western Railway (N&W) at its Roanoke Shops in Roanoke, Virginia, between 1941 and 1950. They were the most powerful 4-8-4 steam locomotives ever produced. The class Js, along with class A and Y6 freight locomotives were the N&W's "Big Three" representing the pinnacles of steam technology.
TheNational Museum of Transportation (TNMOT) is a private, 42-acre transportation museum in the Kirkwood suburb of St. Louis, Missouri. Founded in 1944, it restores, preserves, and displays a wide variety of vehicles spanning 15 decades of American history: cars, boats, aircraft, and in particular, locomotives and railroad equipment from around the United States. The museum is also home to a research library of transportation-related memorabilia and documents.
The Lark was an overnight passenger train of the Southern Pacific Company on the 470-mile (760 km) run between San Francisco and Los Angeles. It became a streamliner in 1941 and was discontinued on April 8, 1968. The Lark ran along the same route as the Coast Daylight and was often pulled by a locomotive wearing the famous Daylight paint scheme of orange, red, and black.
The AC-9 was one of two Southern Pacific Railroad's articulated steam locomotive classes that ran smokebox forward after 1920. Twelve AC-9 class locomotives were built by Lima in 1939 and were Southern Pacific's largest and heaviest steam engines, partly a consequence of low quality coal these engines were designed to burn.
The Exposition Flyer was a passenger train jointly operated by the Chicago, Burlington & Quincy (CB&Q), Denver & Rio Grande Western (D&RGW), and Western Pacific (WP) railroads between Chicago and Oakland, California, for a decade between 1939 and 1949, before being replaced by the famed California Zephyr.
Southern Pacific No. 1744 is a preserved American class "M-6" 2-6-0 "Mogul" type steam locomotive built by the Baldwin Locomotive Works for the Southern Pacific Railroad in November 1901. Originally equipped with Vauclain compound cylinders, it was rebuilt with conventional cylinders in 1912. It operated for many years out of Oakland, California on the Southern Pacific's Western Division and in California's Central Valley where the locomotive and its classmates were fondly called “Valley Mallets” by their crews. The locomotive was made famous in later years by pulling some of the last steam excursions on the SP alongside other steam locomotives, including 4-8-4 4460. In 1959, No. 1744 was donated to the Sons of Utah Pioneers in Corinne, Utah where it remained on static display, until 1980. That year, it was restored by New London Railroad and Village Incorporated to operate on the Heber Valley Railroad in Heber City for the rest of the decade.
