San Bernardino–Riverside Line
The San Bernardino–Riverside is a former Pacific Electric (PE) interurban railway line in the Inland Empire. Unlike most of the company's services, trains did not travel to Downtown Los Angeles and instead provided a suburban service between San Bernardino and Riverside. History Construction on the line north from Riverside began in 1908, but was ceased due to a disagreement between Pacific Electric owner Henry E. Huntington and Union Pacific President E. H. Harriman. Service began in Riverside on April 7, 1911, operating on Main Street, First Street, and La Cadena Drive as far north as Center Street in West Highgrove. In 1913, work began to complete the line, with an extension north to Colton opening on October 4, 1913 and completing to San Bernardino station on December 13. By January 1916 through-routing with the Redlands Line had begun, forming the Redlands–Riverside Line. Between April and June 1928 through-routing was changed to the Riverside–Ar ...

Interurban
The Interurban (or radial railway in Europe and Canada) is a type of electric railway, with streetcar-like electric self-propelled rail cars which run within and between cities or towns. They were very prevalent in North America between 1900 and 1925 and were used primarily for passenger travel between cities and their surrounding suburban and rural communities. The concept spread to countries such as Japan, the Netherlands, Switzerland, Belgium, Italy and Poland. Interurban as a term encompassed the companies, their infrastructure, their cars that ran on the rails, and their service. In the United States, the early 1900s interurban was a valuable economic institution. Most roads between towns and many town streets were unpaved. Transportation and haulage was by horse-drawn carriages and carts. The interurban provided reliable transportation, particularly in winter weather, between the town and countryside. In 1915, of interurban railways were operating in the United States ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Santa Ana River
The Santa Ana River is the largest river entirely within Southern California in the United States. It rises in the San Bernardino Mountains and flows for most of its length through San Bernardino and Riverside Counties, before cutting through the northern Santa Ana Mountains via Santa Ana Canyon and flowing southwest through urban Orange County to drain into the Pacific Ocean. The Santa Ana River is long,U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map accessed March 16, 2011 and its drainage basin is in size. The Santa Ana drainage basin has a diversity of terrain, ranging from high peaks of inland mountains in the north and east, to the hot, dry interior and semi-desert basins of the Inland Empire, to the flat coastal plain of Orange County. Although it includes areas of alpine and highland forest, the majority of the watershed consists of arid desert and chaparral environments. Due to low regional rainfall, the river ...

Light Rail In California
Light or visible light is electromagnetic radiation that can be perceived by the human eye. Visible light is usually defined as having wavelengths in the range of 400–700 nanometres (nm), corresponding to frequencies of 750–420 terahertz, between the infrared (with longer wavelengths) and the ultraviolet (with shorter wavelengths). In physics, the term "light" may refer more broadly to electromagnetic radiation of any wavelength, whether visible or not. In this sense, gamma rays, X-rays, microwaves and radio waves are also light. The primary properties of light are intensity, propagation direction, frequency or wavelength spectrum and polarization. Its speed in a vacuum, 299 792 458 metres a second (m/s), is one of the fundamental constants of nature. Like all types of electromagnetic radiation, visible light propagates by massless elementary particles called photons that represents the quanta of electromagnetic field, and can be analyzed as both waves and particles ...

Pacific Electric Routes
The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continents of Asia and Oceania in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), this largest division of the World Ocean—and, in turn, the hydrosphere—covers about 46% of Earth's water surface and about 32% of its total surface area, larger than Earth's entire land area combined .Pacific Ocean .

Riverside–Rialto Line
Riverside–Rialto was an interurban train service operated by the Pacific Electric Railway from 1914 to 1940, running from Downtown Los Angeles to Downtown Riverside. This was the longest service in the Pacific Electric system, and the only line to have exclusive trackage owned by the Union Pacific instead of the Southern Pacific Railroad. The line reached its highest ridership the year it opened but never recovered at a time when the Inland Empire was far less populated and a commute of that distance was rare. History The line was initially constructed in 1907 by the Riverside Portland Cement Company to link their new plant to the national rail network at Riverside. Operating as The Crescent City Railway Company, service was contracted out to The Riverside & Arlington Railway Company who began regular operations on May 18, 1908. The line primarily served plant workers. Riverside & Arlington would go on to be absorbed into Pacific Electric as a result of the Gre ...

Truss Bridge
A truss bridge is a bridge whose load-bearing superstructure is composed of a truss, a structure of connected elements, usually forming triangular units. The connected elements (typically straight) may be stressed from tension, compression, or sometimes both in response to dynamic loads. The basic types of truss bridges shown in this article have simple designs which could be easily analyzed by 19th and early 20th-century engineers. A truss bridge is economical to construct because it uses materials efficiently. Design The nature of a truss allows the analysis of its structure using a few assumptions and the application of Newton's laws of motion according to the branch of physics known as statics. For purposes of analysis, trusses are assumed to be pin jointed where the straight components meet, meaning that taken alone, every joint on the structure is functionally considered to be a flexible joint as opposed to a rigid joint with strength to maintain its own shape, and ...

Steel
Steel is an alloy made up of iron with added carbon to improve its strength and fracture resistance compared to other forms of iron. Many other elements may be present or added. Stainless steels that are corrosion- and oxidation-resistant typically need an additional 11% chromium. Because of its high tensile strength and low cost, steel is used in buildings, infrastructure, tools, ships, trains, cars, machines, electrical appliances, weapons, and rockets. Iron is the base metal of steel. Depending on the temperature, it can take two crystalline forms (allotropic forms): body-centred cubic and face-centred cubic. The interaction of the allotropes of iron with the alloying elements, primarily carbon, gives steel and cast iron their range of unique properties. In pure iron, the crystal structure has relatively little resistance to the iron atoms slipping past one another, and so pure iron is quite ductile, or soft and easily formed. In steel, small amounts of carb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sunset Route
The Sunset Route is a main line of the Union Pacific Railroad running between Southern California and New Orleans, Louisiana. The name traces its origins to the Galveston, Harrisburg and San Antonio Railway, a Southern Pacific Railway subsidiary which was known as the ''Sunset Route'' as early as 1874. The line was built by several different companies and largely consolidated under Southern Pacific. Upon Southern Pacific Railroad's merger with Union Pacific in 1996, less than 25% of the route was double-tracked. Efforts to expand double-trackage were ongoing as of the late 2000s and early 2010s, with over seventy percent of the route having two tracks by 2012. Usage The line is primarily used for freight by the Union Pacific. BNSF shares ownership of the Lafayette Subdivision. By 2007, 45 trains daily were operating through Maricopa, Arizona. The Amtrak ''Sunset Limited'' operates three round-trips weekly over the entirety of the route with the ''Texas Eagle'' attached between S ...
