Diamond And Caldor Railway
The Diamond and Caldor Railway was a common carrier narrow gauge railroad operating in El Dorado County, California, in the United States. The 34-mile railroad was primarily a logging railroad but also operated some passenger service. History The railroad was built by the California Door Company which was founded in 1884 in Oakland, California. The company bought 30,000 acres of wooded land in El Dorado county in 1899 as a source of timber for their plant. They initially used oxen to haul felled trees to their sawmill on the Cosumnes River. In 1901 they experimented with steam tractors for log haulage, but this was unsuccessful. In 1902, a steam-powered sawmill was constructed at Caldor, California and a planning mill 36 miles away at Diamond Springs on the Central Pacific Railroad. In late 1903, the company began construction of a narrow-gauge railroad to connect the two mills. The railroad was formally incorporated on 9 February 1904, and opened in 1905. It ran along the No ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diamond & Caldor Railway - Western Section
Diamond is a solid form of the element carbon with its atoms arranged in a crystal structure called diamond cubic. Another solid form of carbon known as graphite is the chemically stable form of carbon at room temperature and pressure, but diamond is metastable and converts to it at a negligible rate under those conditions. Diamond has the highest hardness and thermal conductivity of any natural material, properties that are used in major industrial applications such as cutting and polishing tools. They are also the reason that diamond anvil cells can subject materials to pressures found deep in the Earth. Because the arrangement of atoms in diamond is extremely rigid, few types of impurity can contaminate it (two exceptions are boron and nitrogen). Small numbers of defects or impurities (about one per million of lattice atoms) color diamond blue (boron), yellow (nitrogen), brown (defects), green (radiation exposure), purple, pink, orange, or red. Diamond also has a very ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shay Locomotive
The Shay locomotive is a geared steam locomotive that originated and was primarily used in North America. The locomotives were built to the patents of Ephraim Shay, who has been credited with the popularization of the concept of a ''geared steam locomotive''. Although the design of Ephraim Shay's early locomotives differed from later ones, there is a clear line of development that joins all Shays. Shay locomotives were especially suited to logging, mining and industrial operations and could operate successfully on steep or poor quality track. Development Ephraim Shay (1839–1916), was a schoolteacher, a clerk in an American Civil War hospital, a civil servant, a logger, a merchant, a railway owner, and an inventor who lived in Michigan. In the 1860s, he became a logger and wanted a better way to move logs to the mill than on winter snow sleds. He built his own tramway in 1875, on gauge track on wooden ties, allowing him to log all year round. Two years later he develope ...

3 Ft Gauge Railways In The United States
3 (three) is a number, numeral and digit. It is the natural number following 2 and preceding 4, and is the smallest odd prime number and the only prime preceding a square number. It has religious or cultural significance in many societies. Evolution of the Arabic digit The use of three lines to denote the number 3 occurred in many writing systems, including some (like Roman and Chinese numerals) that are still in use. That was also the original representation of 3 in the Brahmic (Indian) numerical notation, its earliest forms aligned vertically. However, during the Gupta Empire the sign was modified by the addition of a curve on each line. The Nāgarī script rotated the lines clockwise, so they appeared horizontally, and ended each line with a short downward stroke on the right. In cursive script, the three strokes were eventually connected to form a glyph resembling a with an additional stroke at the bottom: ३. The Indian digits spread to the Caliphate in the 9th ...

Railroad Speeder
A speeder (also known as a section car, railway motor car, putt-putt, track-maintenance car, crew car, jigger, trike, quad, trolley, inspection car, or a draisine) is a small railcar formerly used around the world by track inspectors and work crews to move quickly to and from work sites. Although slow compared to a train or car, it is called ''speeder'' because it is faster than a human-powered vehicle such as a handcar. Motorised inspection cars date back to at least 1896, when it was reported that the U.S. Daimler Motor Company created a gasoline-powered rail inspection car capable of 15 mph (24 km/h). In the 1990s, many speeders were replaced by pickup trucks or sport utility vehicles with additional flanged wheels that could be lowered for travelling on rails, called "road–rail vehicles" or hi-rails for "highway-railroad". Speeders are collected by hobbyists, who refurbish them for excursions organized by the North American Railcar Operators Association in the U.S ...

Madera Sugar Pine Company
The Madera Sugar Pine Company was a lumber company that operated in the Sierra Nevada region of California during the late 19th and early 20th centuries. It was known for its use of innovative technologies, such as the first log flume and logging railroad in the southern Sierra, and the adoption of the Steam Donkey engine in commercial logging. The company had a significant impact on the region, leading to the founding of several towns, including Madera, Fish Camp, and Sugar Pine, as well as the growth of Fresno Flats and the formation of Madera County. In addition, the company contributed to the agriculture in California in California through its production of wooden shipping boxes and was involved in a U.S. Supreme Court case related to employer obligations. At its peak, The Madera Sugar Pine Company employed over 600 men in its logging operations and another 1,000 men in its lumbering plant, and produced 50 million board feet of lumber annually. Most of the company's pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lima Locomotive Works
Lima Locomotive Works was an American firm that manufactured railroad locomotives from the 1870s through the 1950s. The company took the most distinctive part of its name from its main shop's location in Lima, Ohio. The shops were located between the Erie Railroad main line, the Baltimore & Ohio's Cincinnati-Toledo main line and the Nickel Plate Road main line and shops. The company is best known for producing the Shay geared logging-steam locomotive, developed by Ephraim Shay, and for William E. Woodard's "Super Power" advanced steam locomotive concept – exemplified by the prototype 2-8-4 Berkshire, Lima demonstrator A-1. In World War II the Lima plant produced the M4A1 version of the M4 Sherman tank. History In 1878 James Alley contracted the Lima Machine Works to build a steam locomotive that Ephraim Shay had designed. In April 1880, Lima rebuilt Ephraim Shay's original design, using vertically side-mounted pistons mounted on the right, connected to a drive l ...

Baldwin Locomotive Works
The Baldwin Locomotive Works (BLW) was an American manufacturer of railroad locomotives from 1825 to 1951. Originally located in Philadelphia, it moved to nearby Eddystone, Pennsylvania, in the early 20th century. The company was for decades the world's largest producer of steam locomotives, but struggled to compete as demand switched to diesel locomotives. Baldwin produced the last of its 70,000-plus locomotives in 1951, before merging with the Lima-Hamilton Corporation on September 11, 1951, to form the Baldwin-Lima-Hamilton Corporation. The company has no relation to the E.M. Baldwin and Sons of New South Wales, Australia, a builder of small diesel locomotives for sugar cane railroads. History: 19th century Beginning The Baldwin Locomotive Works had a humble beginning. Matthias W. Baldwin, the founder, was a jeweler and whitesmith, who, in 1825, formed a partnership with machinist David H. Mason, and engaged in the manufacture of bookbinders' tools and cylinders for cal ...

Railway Coupling
A coupling (or a coupler) is a mechanism typically placed at each end of a railway vehicle that connects them together to form a train. A variety of coupler types have been developed over the course of railway history. Key issues in their design include strength, reliability, ease of making connections and operator safety. The equipment that connects the couplings to the vehicles is the draft gear or draw gear and these must absorb the stresses of coupling and train acceleration. Nomenclature Compatible and similar couplings or couplers are frequently referred to using widely differing make, brand, or regional names, or nicknames, which can make describing standard or typical designs confusing. Dimensions and ratings noted in these articles are usually of nominal or typical components and systems, though standards and practices also vary widely with railway, region, and era. Buffers and chain The basic type of coupling on railways following the British tradition is the bu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Air Brake (rail)
A railway air brake is a railway brake power braking system with compressed air as the operating medium. Modern trains rely upon a fail-safe air brake system that is based upon a design patented by George Westinghouse on April 13, 1869. The Westinghouse Air Brake Company was subsequently organized to manufacture and sell Westinghouse's invention. In various forms, it has been nearly universally adopted. The Westinghouse system uses air pressure to charge air reservoirs (tanks) on each car. Full air pressure causes each car to release the brakes. A subsequent reduction or loss of air pressure causes each car to apply its brakes, using the compressed air stored in its reservoirs. Overview Straight air brake In the air brake's simplest form, called the ''straight air system'', compressed air pushes on a piston in a cylinder. The piston is connected through mechanical linkage to brake shoes that can rub on the train wheels, using the resulting friction to slow the train. The ...

Interstate Commerce Commission
The Interstate Commerce Commission (ICC) was a regulatory agency in the United States created by the Interstate Commerce Act of 1887. The agency's original purpose was to regulate railroads (and later trucking) to ensure fair rates, to eliminate rate discrimination, and to regulate other aspects of common carriers, including interstate bus lines and telephone companies. Congress expanded ICC authority to regulate other modes of commerce beginning in 1906. Throughout the 20th century, several of ICC's authorities were transferred to other federal agencies. The ICC was abolished in 1995, and its remaining functions were transferred to the Surface Transportation Board. The Commission's five members were appointed by the President with the consent of the United States Senate. This was the first independent agency (or so-called ''Fourth Branch''). Creation The ICC was established by the Interstate Commerce Act of 1887, which was signed into law by President Grover Cleveland. The cr ...

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] |
