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. 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 System 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 the Bay Bridge Railway in January of 1939. This railway con ...

Southern Pacific Transportation Company
The Southern Pacific (or Espee from the railroad initials) 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 company ...

San Francisco–Oakland Bay Bridge
The San Francisco–Oakland Bay Bridge, commonly referred to as the Bay Bridge, is a complex of bridges spanning San Francisco Bay in California. As part of Interstate 80 in California, Interstate 80 and the direct road between San Francisco and Oakland, California, Oakland, it carries about 260,000 vehicles a day on its two decks. It includes one of the List of longest suspension bridge spans, longest bridge spans in the United States. The toll bridge was conceived as early as the California gold rush days, with "Emperor" Joshua Norton famously advocating for it, but construction did not begin until 1933. Designed by Charles H. Purcell, and built by American Bridge Company, it opened on Thursday, November 12, 1936, six months before the Golden Gate Bridge. It originally carried automobile traffic on its upper deck, with trucks, cars, buses and interurban, commuter trains on the lower, but after the Key System abandoned its rail service on April 20, 1958, the lower deck was conv ...

Oakland Tribune
The ''Oakland Tribune'' was a daily newspaper published in Oakland, California, and a predecessor of the '' East Bay Times''. It was published by the Bay Area News Group (BANG), a subsidiary of MediaNews Group. Founded in 1874, the ''Tribune'' rose to become an influential daily newspaper. With the decline of print media, in 2016, the paper announced that the ''Tribune'', along with its owner's other newspapers in the East Bay, would be folded into a new newspaper titled the ''East Bay Times'' starting April 5, 2016. The former nameplates of the consolidated newspapers will continue to be published every Friday as weekly community supplements. ''Oakland Voices'' is also a successor of the ''Tribune'', developing out of a collaboration with the Maynard Institute for Journalism Education Origin The ''Tribune'' was founded February 21, 1874, by George Staniford and Benet A. Dewes. The ''Oakland Daily Tribune'' was first printed at 468 Ninth St. as a 4-page, 3-column newspaper, 6 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Car And Foundry Company
ACF Industries, originally the American Car and Foundry Company (abbreviated as ACF), is an American manufacturer of railroad railroad car, rolling stock. One of its subsidiaries was once (1925–54) a manufacturer of Motor bus, motor coaches and trolleybus, trolley coaches under the brand names of (first) ACF and (later) J. G. Brill Company, ACF-Brill. Today, the company is known as ACF Industries LLC and is based in St. Charles, Missouri. It is owned by investor Carl Icahn. History The American Car and Foundry Company was originally formed and incorporated in New Jersey in 1899 as a result of the merger of thirteen smaller railroad car manufacturers: Later in 1899, ACF acquired the Bloomsburg Car Manufacturing Company of Bloomsburg, Pennsylvania. Orders for new freight cars were made very quickly, with several hundred cars ordered in the first year alone. Two years later, ACF acquired the Jackson and Sharp Company (founded 1863 in Wilmington, Delaware) and the Common Sense ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Catenary
In physics and geometry, a catenary ( , ) is the curve that an idealized hanging chain or wire rope, 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 Catenary arch, 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, MathWorld or, particularly in the materials sciences, an example of a funicular curve, funicular. Rope statics describes catenaries in a classic statics problem involving a hanging rope. Mathematically, the catenary curve is the Graph of a function, 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 ha ...

Railway Electrification System
Railway electrification is the use of electric power for the propulsion of rail transport. 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 and contacted by a pantograph, or a third rail mounted at track level and contacted by a sliding " pickup ...

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 Penin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Key System Mole
The Key System Mole was an interurban train and ferry pier on the San Francisco Bay. It served as an interchange point in the East Bay for Key System passengers traveling to and from San Francisco. It opened to passenger service in 1903 and was upgraded several times until 1933 when it was partially destroyed by a fire. Passenger service ended in 1939, and segments of the structure were partially reused in construction of the San Francisco–Oakland Bay Bridge. History Opening, popularity, and expansion The troubled California & Nevada Railroad had begun construction of a ferry pier in Oakland, but its plans were never realized. Francis Marion "Borax" Smith purchased the railroad in order to gain access to its right of way and waterfront operations, as well as use the abandoned pier as a starting point for his own passenger mole. Transbay service began on October 26, 1903. The original station building was designed by Walter J. Mathews and featured three tracks with one ...

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, Oakland, California, West Oakland. The Oakland Long Wharf was built, beginning 1868, by the Central Pacific Railroad on what was previously Oakland Point, Oakland, California, 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 (architecture), Mole. Portions of the Wharf lasted until the 1960s. The site is now part of the facilities of the Port of Oakland, while passenger train service operates at the nearby Oakland – Jack London Square station, Jack London Square/Dellums Station and another nearby station ...

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 Fruitv ... [...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 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 2.8 million in 2024, it is the most populous subregion in the Bay Area, containing the second- and third-most populous Bay Area counties of Alameda (1.7 million) and Contra Costa (1.1 million). Oakland is the largest city in the East Bay by population 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, Hayward, Livermore, Pleasanton, San Ramon, and Walnut Creek. History and development Although initial development in the greater Bay Area focused on San Francisco, the coastal East Bay ...

Steam Engine
A steam engine is a heat engine that performs Work (physics), 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 (locomotive), cylinder. This pushing force can be transformed by a connecting rod and Crank (mechanism), crank into rotational force for work. The term "steam engine" is most commonly applied to reciprocating engines as just described, although some authorities have also referred to the steam turbine and devices such as Hero's aeolipile as "steam engines". The essential feature of steam engines is that they 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 Boiler (power generation), boilers etc.), such as railway steam locomot ...
