Southern Pacific Class GS-1
The Southern Pacific GS-1 was a class of conventional 4-8-4, 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. History Design and abilities During the Great Depression in the 1930s, the Southern Pacific Railroad (SP) needed more power for their heavy passenger train service... They ordered a batch of fourteen 4-8-4 GS-1 locomotives from the Baldwin Locomotives Works between May and July 1930. The prefix ''GS'' indicates ''Golden State''. Originally, the GS-1s' operating boiler pressure was , but would eventually increase to . The GS-1s were the first SP steam locomotives to have the cylinders connected to the locomotive frame, frame in one piece. These locomotives operated on saturated steam for the injector, steam heat, automatic lubrica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Feedwater Heater
A feedwater heater is a power plant component used to pre-heat water delivered to a steam generating boiler. Preheating the feedwater reduces the irreversibilities involved in steam generation and therefore improves the thermodynamic efficiency of the system.Fundamentals of Steam Power by Kenneth Weston, This reduces plant operating costs and also helps to avoid to the boiler metal when the feedwater is introduced back into the steam cycle.

4-8-4 Locomotives
Under the Whyte notation for the classification of steam locomotives, 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. Overview Development The wheel arrangement was a progression from the Mountain type and, like the Berkshire and Hudson types, an example of the "Super Power" concept in steam locomotive design that made use of the larger firebox that could be supported by a four-wheel trailing truck, which allowed greater production of steam. The four-wheel leading truck gave stability at speed and the eight driving wheels gave greater adhesion. The type evolved in the United States soon after the Lima Locomotive Works introduced the ...

Vacuum Brake
The vacuum brake is a brake, braking system employed on trains and introduced in the mid-1860s. A variant, the automatic vacuum brake system, became almost universal in British train equipment and in countries influenced by British practice. Vacuum brakes also enjoyed a brief period of adoption in the United States, primarily on narrow-gauge railroads. Their limitations caused them to be progressively superseded by Railway air brake, compressed air systems starting in the United Kingdom from the 1970s onward. The vacuum brake system is now obsolete; it is not in large-scale usage anywhere in the world, other than in South Africa, largely supplanted by railway air brake, air brakes. Introduction In the earliest days of railways, trains were slowed or stopped by the application of manually applied brakes on the locomotive and in brake vehicles through the train, and later by steam power brakes on locomotives. This was clearly unsatisfactory, given the slow and unreliable response ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Richvale (also, Richland, Silbys Switch, Silsby) is a small census-designated place (population 244) in Butte County, California, US, south of Chico and west of Oroville. The primary crop grown in the area surrounding Richvale is rice, irrigated from the Oroville Dam on the Feather River. Several farmers in the area are known for organic farming. The population was 244 at the 2010 census. Richvale is located at 39° 29' 38" North, 121° 44' 41" West, above sea level. The ZIP Code is 95974. The community is inside area code 530. History Legend says that the name "Richvale" (meaning " fertile valley") was coined by con men to sell worthless plots of land to wheat farmers from Nebraska and Kansas. The developers (Richvale Land Company) changed the name from Selby Switch (a railroad siding) to Richvale in 1909. The place was settled in 1911, and a post office opened that same year. Farmers in the Midwest were shown lush pictures of California's Sacramento Valley and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boiler Explosion
A boiler explosion is a catastrophic failure of a boiler. There are two types of boiler explosions. One type is a failure of the pressure parts of the steam and water sides. There can be many different causes, such as failure of the safety valve, corrosion of critical parts of the boiler, or low water level. Corrosion along the edges of lap joints was a common cause of early boiler explosions. In steam locomotive boilers, as knowledge was gained by trial and error in early days, the explosive situations and consequent damage due to explosions were inevitable. However, improved design and maintenance markedly reduced the number of boiler explosions by the end of the 19th century. Further improvements continued in the 20th century. On land-based boilers, explosions of the pressure systems happened regularly in stationary steam boilers in the Victorian era, but are now very rare because of the various protections provided, and because of regular inspections compelled by governmen ...

Peninsula Commute
The Peninsula Commute, also known as the Southern Pacific Peninsula or just Peninsula, was the common name for commuter rail service between San Jose, California, San Jose and San Francisco, California, San Francisco on the San Francisco Peninsula. This service ran as a private, for-profit enterprise beginning in 1863. Due to operating losses, the Southern Pacific Transportation Company, Southern Pacific Railroad (SP) petitioned to discontinue the service in 1977. Subsidies were provided through the California Department of Transportation (Caltrans) in 1980 to continue service, and it was renamed Caltrain in 1985. History Since 1863 the San Francisco Peninsula, the series of towns (and later, cities) between San Francisco, California, San Francisco and San Jose, California, San Jose, has been served by a railroad. The San Francisco and San Jose Railroad first provided freight and passenger service, followed by its successor, the Southern Pacific, and then briefly by the Californi ...

Passenger Train
A passenger train is a train used to transport people along a railroad line, as opposed to a freight train that carries goods. These trains may consist of unpowered passenger railroad cars (also known as coaches or carriages) push-pull train, hauled by one or more locomotives, or may be self-propelled; self propelled passenger trains are known as multiple units or railcars. Passenger trains stop at Train station, stations or depots, where passengers may board and disembark. In most cases, passenger trains operate on a fixed Public transport timetable, schedule and have priority over freight trains. Car design and the general safety of passenger trains have dramatically evolved over time, making travel by rail remarkably safe. Some passenger trains, both long-distance and short-distance, use Bilevel car, bi-level (double-decker) cars to carry more passengers per train. Sleeper trains include sleeping cars with beds. Passenger trains hauled by locomotives are more expensive to op ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
