Interurban Electric Railway
The East Bay Electric Lines were a unit of the Southern Pacific Railroad that operated electric interurban-type trains in the East Bay region of the San Francisco Bay Area.Tufveson.Ford (1977). Beginning in 1862, the SP and its predecessors operated local steam-drawn ferry-train passenger service in the East Bay on an expanding system of lines, but in 1902 the Key SystemSappers (1948).Demoro (Parts 1 and 2). started a competing system of electric lines and ferries. The SP then drew up plans to expand and electrify its system of lines and this new service began in 1911. The trains served the cities of Berkeley, Albany, Emeryville, Oakland, Alameda, and San Leandro transporting commuters to and from the large Oakland Pier (the "mole") and SP Alameda Pier. A fleet of ferry boats ran between these piers and the docks of the Ferry Building on the San Francisco Embarcadero. The East Bay Electric Lines became the Interurban Electric Railway (IER) in anticipation of the opening of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Southern Pacific Railroad
The Southern Pacific (or Espee from the railroad initials- SP) 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 original Southern Pacific began in 1865 as a land holding company. The last incarnation of the Southern Pacific, the Southern Pacific Transportation Company, was founded in 1969 and assumed control of the Southern Pacific system. The Southern Pacific Transportation Company was acquired in 1996 by the Union Pacific Corporation and merged with their Union Pacific Railroad. The Southern Pacific legacy founded hospitals in San Francisco, Tucson, and Houston. In the 1970s, it also founded a telecommunications network with a state-of-the-art microwave and fiber optic backbone. This telecommunications network became part of Sprint, a compa ...

San Francisco Ferry Building
The San Francisco Ferry Building is a terminal for ferries that travel across the San Francisco Bay, a food hall and an office building. It is located on The Embarcadero in San Francisco, California and is served by Golden Gate Ferry and San Francisco Bay Ferry routes. On top of the building is a clock tower with four clock dials, each in diameter, which can be seen from Market Street, a main thoroughfare of the city. Designed in 1892 by American architect A. Page Brown in the Beaux-Arts style, the ferry building was completed in 1898. At its opening, it was the largest project undertaken in the city up to that time. One of Brown's design inspirations for the clock tower may have been the current 16th-century iteration of the 12th-century Giralda bell tower in Seville, Spain. The entire length of the building on both frontages is based on an arched arcade. With decreased use since the 1950s, after bridges were constructed to carry transbay traffic and most streetcar r ...

Catenary
In physics and geometry, a catenary (, ) is the curve that an idealized hanging chain or cable assumes under its own weight when supported only at its ends in a uniform gravitational field. The catenary curve has a U-like shape, superficially similar in appearance to a parabola, which it is not. The curve appears in the design of certain types of arches and as a cross section of the catenoid—the shape assumed by a soap film bounded by two parallel circular rings. The catenary is also called the alysoid, chainette,MathWorld or, particularly in the materials sciences, funicular. Rope statics describes catenaries in a classic statics problem involving a hanging rope. Mathematically, the catenary curve is the graph of the hyperbolic cosine function. The surface of revolution of the catenary curve, the catenoid, is a minimal surface, specifically a minimal surface of revolution. A hanging chain will assume a shape of least potential energy which is a catenary. Galileo Galil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Railway Electrification System
A railway electrification system supplies electric power to railway trains and trams without an on-board prime mover or local fuel supply. Electric railways use either electric locomotives (hauling passengers or freight in separate cars), electric multiple units (passenger cars with their own motors) or both. Electricity is typically generated in large and relatively efficient generating stations, transmitted to the railway network and distributed to the trains. Some electric railways have their own dedicated generating stations and transmission lines, but most purchase power from an electric utility. The railway usually provides its own distribution lines, switches, and transformers. Power is supplied to moving trains with a (nearly) continuous conductor running along the track that usually takes one of two forms: an overhead line, suspended from poles or towers along the track or from structure or tunnel ceilings, or a third rail mounted at track level and contacted by a s ...

Collis Potter Huntington
Collis Potter Huntington (October 22, 1821 – August 13, 1900) was an American industrialist and railway magnate. He was one of the Big Four of western railroading (along with Leland Stanford, Mark Hopkins, and Charles Crocker) who invested in Theodore Judah's idea to build the Central Pacific Railroad as part of the first U.S. transcontinental railroad. Huntington helped lead and develop other major interstate lines, such as the Southern Pacific Railroad and the Chesapeake & Ohio Railway (C&O), which he was recruited to help complete. The C&O, completed in 1873, fulfilled a long-held dream of Virginians of a rail link from the James River at Richmond to the Ohio River Valley. The new railroad facilities adjacent to the river there resulted in expansion of the former small town of Guyandotte, West Virginia into part of a new city which was named Huntington in his honor. Turning attention to the eastern end of the line at Richmond, Huntington directed the C&O's Peninsula Ex ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Oakland Long Wharf
The Oakland Long Wharf was an 11,000-foot railroad wharf and ferry pier along the east shore of San Francisco Bay located at the foot of Seventh Street in West Oakland. The Oakland Long Wharf was built, beginning 1868, by the Central Pacific Railroad on what was previously Oakland Point. Beginning November 8, 1869, it served as the west coast terminus of the First transcontinental railroad. In the 1880s, Southern Pacific Railroad took over the CPRR, extending it and creating a new ferry terminal building with the official station name Oakland Pier. The entire structure became commonly and popularly called the Oakland Mole. Portions of the Wharf lasted until the 1960s. The site is now part of the facilities of the Port of Oakland, while passenger service runs to the nearby Jack London Square/Dellums Station History The first use of the site for boats was in 1852, when Gibbons' Wharf was constructed at Gibbons' Point, westward into San Francisco Bay. In 1862, Gibbons' Point ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
San Francisco And Alameda Railroad
The San Francisco and Alameda Railroad (SF&A) was a short-lived railroad company in the East Bay area of the San Francisco Bay Area. The railroad line opened 1864–1865 from Alameda Terminal on Alameda Island to Hayward, California, with ferry service between Alameda Terminal and San Francisco started in 1864. After being bankrupted by the 1868 Hayward earthquake, it was acquired by a subsidiary of the Central Pacific Railroad in August 1869. Part of the SF&A line between Alameda Terminal and San Leandro served as a portion of the First transcontinental railroad starting in September 1869 (though most was replaced by the San Francisco and Oakland Railroad by November 1869), while the southern section was abandoned in 1873. The remaining part of the line became part of the Southern Pacific Railroad. From 1911 to 1941, the section on Alameda was used for electrified commuter service. Freight service on Alameda lasted until 1960. The middle section of the SF&A line between Fru ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
East Bay
The East Bay is the eastern region of the San Francisco Bay Area and includes cities along the eastern shores of the San Francisco Bay and San Pablo Bay. The region has grown to include inland communities in Alameda and Contra Costa counties. With a population of roughly 2.5 million in 2010, it is the most populous subregion in the Bay Area. Oakland is the largest city in the East Bay and the third largest in the Bay Area. The city serves as a major transportation hub for the U.S. West Coast, and its port is the largest in Northern California. Increased population has led to the growth of large edge cities such as Alameda, Concord, Emeryville, Fremont, Livermore, Pleasanton, San Ramon and Walnut Creek. History and development Although initial development in the larger Bay Area focused on San Francisco, the coastal East Bay came to prominence in the middle of the nineteenth century as the part of the Bay Area most accessible by land from the east.

Steam Engine
A steam engine is a heat engine that performs mechanical work using steam as its working fluid. The steam engine uses the force produced by steam pressure to push a piston back and forth inside a cylinder. This pushing force can be transformed, by a connecting rod and crank, into rotational force for work. The term "steam engine" is generally applied only to reciprocating engines as just described, not to the steam turbine. Steam engines are external combustion engines, where the working fluid is separated from the combustion products. The ideal thermodynamic cycle used to analyze this process is called the Rankine cycle. In general usage, the term ''steam engine'' can refer to either complete steam plants (including boilers etc.), such as railway steam locomotives and portable engines, or may refer to the piston or turbine machinery alone, as in the beam engine and stationary steam engine. Although steam-driven devices were known as early as the aeolipile in the f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Central Pacific Railroad
The Central Pacific Railroad (CPRR) was a rail company chartered by Pacific Railroad Acts, U.S. Congress in 1862 to build a railroad eastwards from Sacramento, California, to complete the western part of the "First transcontinental railroad" in North America. Incorporated in 1861, CPRR ceased operation in 1885 when it was acquired by Southern Pacific Railroad as a leased line. Following the completion of the Pacific Railroad Surveys in 1855, several national proposals to build a transcontinental railroad failed because of the energy consumed by political disputes over slavery. With the secession of Southern United States, the South in 1861, the modernizers in the Republican Party (US), Republican Party controlled the US Congress. They passed Pacific Railroad Acts, legislation in 1862 authorizing the central rail route with financing in the form of land grants and government railroad bond, which were all eventually repaid with interest. The government and the railroads both shared ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
