Taylor Yard, Los Angeles
Taylor Yard is the site of the Rio de Los Angeles State Park along with the new Metrolink maintenance facility located on the southern end of the former yard grounds in Los Angeles. The former railway station and classification yard and former headquarters of Southern Pacific Railroad operations in Southern California was purchased by the Southern Pacific in 1911 and continually reshaped and remade over the course of the early 20th century for the purposes of inspection, repair, and storage of freight cars on the Southern Pacific Fruit Express line. History Taylor Yard was established in 1911 on the previous site of Taylor Feed Mill (from which the yard gets its name). It was rebuilt in 1949. Competition from the trucking industry and the closure of American manufacturing plants led to the decline of the Yard after the 1950s. In 1983, an average of 25,000 railroad cars moved through Taylor Yard and 1,200 workers were employed in its operations, down from 5,000 in the 1950s. South ...

Rio De Los Angeles State Park
Rio de Los Angeles State Park is a California State Park along the Los Angeles River north of downtown Los Angeles in the neighborhood of Glassell Park, Los Angeles. The park includes restored wetlands featuring native plants as well as sports fields, a children’s playground and a recreation building. Rio de Los Angeles State Park is currently managed in partnership with the City of Los Angeles Department of Parks and Recreation. History The park was built on Taylor Yard, an abandoned freight-switching facility used by the Union Pacific and later the Southern Pacific railroads from the 1920s until 1985. Wildlife slowly began re-inhabiting the area and in the early-2000s an effort was begun to transform the abandoned brownfield land into a recreation area. The property was eventually purchased by the City of Los Angeles and demolition of the abandoned train terminals begin. The rail-lines connecting the Taylor Yard to the Union Pacific Railroad were torn out, the corroding train ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glendale Narrows
The Glendale Narrows is a scenic 11 mile (17.7 km) section of the Los Angeles River in the Northeast Los Angeles region of Los Angeles County, California. History The Tongva people used the Los Angeles River as a vital resource, and had village sites in the larger Glendale Narrows region. These villages included Yaanga and Geveronga.

History Of Los Angeles
The history of Los Angeles began in 1781 when 44 settlers from central New Spain (modern Mexico) established a permanent settlement in what is now Downtown Los Angeles, as instructed by Spanish Governor of Las Californias, Felipe de Neve, and authorized by Viceroy Antonio María de Bucareli. After sovereignty changed from Mexico to the United States in 1848, great changes came from the completion of the Santa Fe railroad line from Chicago to Los Angeles in 1885. "Overlanders" flooded in, mostly white Protestants from the Lower Midwest and South. Los Angeles had a strong economic base in farming, oil, tourism, real estate and movies. It grew rapidly with many suburban areas inside and outside the city limits. Its motion picture industry made the city world-famous, and World War II brought new industry, especially high-tech aircraft construction. Politically the city was moderately conservative, with a weak labor union sector. Since the 1960s, growth has slowed—and traffic delays ...

Former Southern Pacific Railroad Stations In California
A former is an object, such as a template, gauge or cutting die, which is used to form something such as a boat's hull. Typically, a former gives shape to a structure that may have complex curvature. A former may become an integral part of the finished structure, as in an aircraft fuselage, or it may be removable, being using in the construction process and then discarded or re-used. Aircraft formers Formers are used in the construction of aircraft fuselage, of which a typical fuselage has a series from the nose to the empennage, typically perpendicular to the longitudinal axis of the aircraft. The primary purpose of formers is to establish the shape of the fuselage and reduce the column length of stringers to prevent instability. Formers are typically attached to longerons, which support the skin of the aircraft. The "former-and-longeron" technique (also called stations and stringers) was adopted from boat construction, and was typical of light aircraft built until the adv ...

Railway Turntable
In rail terminology, a railway turntable or wheelhouse is a device for turning railway rolling stock, usually locomotives, so that they can be moved back in the direction from which they came. Naturally, it is especially used in areas where economic considerations or a lack of sufficient space have served to weigh against the construction of a turnaround wye. In the case of steam locomotives, railways needed a way to turn the locomotives around for return trips as their controls were often not configured for extended periods of running in reverse and in many locomotives the top speed was lower in reverse motion. In the case of diesel locomotives, though most can be operated in either direction, they are treated as having "front ends" and "rear ends" (often determined by reference to the location of the crew cab). When operated as a single unit, the railway company often prefers, or requires, that a diesel locomotive is run "front end" first. When operated as part of a multiple ...

Antimony
Antimony is a chemical element with the symbol Sb (from la, stibium) and atomic number 51. A lustrous gray metalloid, it is found in nature mainly as the sulfide mineral stibnite (Sb2S3). Antimony compounds have been known since ancient times and were powdered for use as medicine and cosmetics, often known by the Arabic name kohl. The earliest known description of the metal in the West was written in 1540 by Vannoccio Biringuccio. China is the largest producer of antimony and its compounds, with most production coming from the Xikuangshan Mine in Hunan. The industrial methods for refining antimony from stibnite are roasting followed by reduction with carbon, or direct reduction of stibnite with iron. The largest applications for metallic antimony are in alloys with lead and tin, which have improved properties for solders, bullets, and plain bearings. It improves the rigidity of lead-alloy plates in lead–acid batteries. Antimony trioxide is a prominent additive for halo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arsenic
Arsenic is a chemical element with the symbol As and atomic number 33. Arsenic occurs in many minerals, usually in combination with sulfur and metals, but also as a pure elemental crystal. Arsenic is a metalloid. It has various allotropes, but only the gray form, which has a metallic appearance, is important to industry. The primary use of arsenic is in alloys of lead (for example, in car batteries and ammunition). Arsenic is a common n-type dopant in semiconductor electronic devices. It is also a component of the III-V compound semiconductor gallium arsenide. Arsenic and its compounds, especially the trioxide, are used in the production of pesticides, treated wood products, herbicides, and insecticides. These applications are declining with the increasing recognition of the toxicity of arsenic and its compounds. A few species of bacteria are able to use arsenic compounds as respiratory metabolites. Trace quantities of arsenic are an essential dietary element in rats, ham ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydrocarbons
In organic chemistry, a hydrocarbon is an organic compound consisting entirely of hydrogen and carbon. Hydrocarbons are examples of group 14 hydrides. Hydrocarbons are generally colourless and hydrophobic, and their odors are usually weak or exemplified by the odors of gasoline and lighter fluid. They occur in a diverse range of molecular structures and phases: they can be gases (such as methane and propane), liquids (such as hexane and benzene), low melting solids (such as paraffin wax and naphthalene) or polymers (such as polyethylene and polystyrene). In the fossil fuel industries, ''hydrocarbon'' refers to the naturally occurring petroleum, natural gas and coal, and to their hydrocarbon derivatives and purified forms. Combustion of hydrocarbons is the main source of the world's energy. Petroleum is the dominant raw-material source for organic commodity chemicals such as solvents and polymers. Most anthropogenic (human-generated) emissions of greenhouse gases are carb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lead
Lead is a chemical element with the symbol Pb (from the Latin ) and atomic number 82. It is a heavy metal that is denser than most common materials. Lead is soft and malleable, and also has a relatively low melting point. When freshly cut, lead is a shiny gray with a hint of blue. It tarnishes to a dull gray color when exposed to air. Lead has the highest atomic number of any stable element and three of its isotopes are endpoints of major nuclear decay chains of heavier elements. Lead is toxic, even in small amounts, especially to children. Lead is a relatively unreactive post-transition metal. Its weak metallic character is illustrated by its amphoteric nature; lead and lead oxides react with acids and bases, and it tends to form covalent bonds. Compounds of lead are usually found in the +2 oxidation state rather than the +4 state common with lighter members of the carbon group. Exceptions are mostly limited to organolead compounds. Like the lighter members of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Structure Relocation
A structure relocation is the process of moving a structure from one location to another. There are two main ways for a structure to be moved: disassembling and then reassembling it at the required destination, or transporting it whole. For the latter, the building is first raised and then may be pushed on temporary rails or dollies if the distance is short. Otherwise, wheels, such as flatbed trucks, are used. These moves can be complicated and require the removal of protruding parts of the building, such as the chimney, as well as obstacles along the journey, such as overhead cables and trees. Reasons for moving a building range from commercial reasons such as scenery to preserving an important or historic building. Moves may also be made simply at the whim of the owner, or to separate a building from the plot of land on which it stands. Equipment Elevating a whole structure is typically done by attaching a temporary steel framework under the structure to support the structure ...

Railway Roundhouse
A railway roundhouse is a building with a circular or semicircular shape used by railways for servicing and storing locomotives. Traditionally, though not always the case today, these buildings surrounded or were adjacent to a turntable. Overview Early steam locomotives normally traveled forwards only. Although reverse operations capabilities were soon built into locomotive mechanisms, the controls were normally optimized for forward travel, and the locomotives often could not operate as well in reverse. Some passenger cars, such as observation cars, were also designed as late as the 1960s for operations in a particular direction. Turntables allowed locomotives or other rolling stock to be turned around for the return journey, and roundhouses, designed to radiate around the turntables, were built to service and store these locomotives. Most modern diesel and electric locomotives can run equally well in either direction, and many are push-pull trains with control cabs at ea ...
