Monongahela Connecting Railroad
The Monongahela Connecting Railroad or Mon Conn is a small industrial railroad in Pittsburgh, Pennsylvania. It was a subsidiary of the Jones & Laughlin Steel Company and a large portion of its work was for its parent company, though it also serves other industries along the line. The railroad is possibly best known for its Hot Metal Bridge, which was used to carry molten iron across the Monongahela River from J&L's Eliza Furnaces to the Bessemer converters (later, open hearth furnaces) and rolling mills at J&L's South Side facility. The railroad was also a dieselization pioneer, buying many early diesel locomotives from Alco, General Electric and other manufacturers. The railroad is still in existence, but in much reduced form. The Monongahela River bridge has been converted to a two-lane automobile bridge, with the adjacent hot metal bridge converted for bicycles. The bridges are collectively called the Hot Metal Bridge. The railroad serves a few small industrial customers a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Allegheny County, Pennsylvania
Allegheny County () is a county in the Commonwealth of Pennsylvania. It is located in Southwestern Pennsylvania. As of the 2020 census, the population was 1,250,578, making it the state's second-most populous county, following Philadelphia County. The county seat is Pittsburgh. Allegheny County is included in the Pittsburgh, PA Metropolitan Statistical Area, and in the Pittsburgh Designated Market Area. Allegheny was the first county in Pennsylvania to be given a Native American name. It was named after the Lenape word for the Allegheny River. The meaning of "Allegheny" is uncertain. It is usually said to mean "fine river". Stewart says that the name may come from a Lenape account of an ancient mythical tribe called ''"Allegewi"'', who lived along the river before being taken over by the Lenape. History Prior to European contact, this area was settled for thousands of years by succeeding cultures of indigenous peoples. During the colonial era, historic native groups kno ...

Railroad
Rail transport (also known as train transport) is a means of transport that transfers passengers and goods on wheeled vehicles running on rails, which are incorporated in tracks. In contrast to road transport, where the vehicles run on a prepared flat surface, rail vehicles (rolling stock) are directionally guided by the tracks on which they run. Tracks usually consist of steel rails, installed on sleepers (ties) set in ballast, on which the rolling stock, usually fitted with metal wheels, moves. Other variations are also possible, such as "slab track", in which the rails are fastened to a concrete foundation resting on a prepared subsurface. Rolling stock in a rail transport system generally encounters lower frictional resistance than rubber-tyred road vehicles, so passenger and freight cars (carriages and wagons) can be coupled into longer trains. The operation is carried out by a railway company, providing transport between train stations or freight customer facili ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Jones & Laughlin Steel Company
The Jones and Laughlin Steel Corporation began as the American Iron Company, founded in 1852 by Bernard Lauth and Benjamin Franklin Jones, a few miles (c 4 km) south of Pittsburgh along the Monongahela River. Lauth's interest was bought in 1854 by James Laughlin. The first firm to bear the name of Jones and Laughlin was organized in 1861 and headquartered at Third & Ross in downtown Pittsburgh. History Originally producing only iron, the enterprise began the production of steel in 1886. Over the ensuing 60 years, the company expanded its facilities and its operations along both sides of the Monongahela River on the South Side of Pittsburgh and along the Ohio River at Aliquippa. The Hot Metal Bridge across the Monongahela River was built to connect Eliza blast furnaces (making pig iron) on the Hazelwood side of the river with the open hearth furnaces (making steel) on the south side of the river. In 1905, a new plant was begun at Aliquippa, Pennsylvania. The company als ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hot Metal Bridge
The Hot Metal Bridge is a truss bridge in Pittsburgh, Pennsylvania, that crosses the Monongahela River. The bridge consists of two parallel spans on a single set of piers: the former Monongahela Connecting Railroad Bridge, built in 1887, on the upstream side and the former Hot Metal Bridge, built in 1900, on the downstream side. The Monongahela Connecting Railroad Bridge carried conventional railroad traffic, while the Hot Metal Bridge connected parts of the J&L Steel mill, carrying crucibles of molten iron from the blast furnaces in ladle transfer cars to the open hearth furnaces on the opposite bank to be converted to steel. During World War II 15% of America's steel making capacity crossed over the Hot Metal Bridge, up to 180 tons per hour. The upstream span was converted to road use after a $14.6 million restoration, and opened by Mayor Tom Murphy with a ceremony honoring former steel workers on June 23, 2000. The bridge connects 2nd Avenue at the Pittsburgh Technology Center ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monongahela River
The Monongahela River ( , )—often referred to locally as the Mon ()—is a U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map accessed August 15, 2011 river on the Allegheny Plateau in North Central West Virginia, north-central West Virginia and Greater Pittsburgh, Southwestern Pennsylvania. The river flows from the confluence of its west and east forks in north-central West Virginia northeasterly into southwestern Pennsylvania, then northerly to Pittsburgh and its confluence with the Allegheny River to form the Ohio River. The river's entire length is navigable via a series of locks and dams. Etymology The Unami language, Unami word ''Monongahela'' means "falling banks", in reference to the geological instability of the river's banks. Moravian Church, Moravian missionary David Zeisberger (1721–1808) gave this account of the naming: "In the Lenape language, Indian tongue the name of this river was ''Mechmenawungihilla'' (alter ...

Bessemer Converter
The Bessemer process was the first inexpensive industrial process for the mass production of steel from molten pig iron before the development of the open hearth furnace. The key principle is removal of impurities from the iron by oxidation with air being blown through the molten iron. The oxidation also raises the temperature of the iron mass and keeps it molten. Related decarburizing with air processes had been used outside Europe for hundreds of years, but not on an industrial scale. One such process (similar to puddling) was known in the 11th century in East Asia, where the scholar Shen Kuo of that era described its use in the Chinese iron and steel industry. In the 17th century, accounts by European travelers detailed its possible use by the Japanese. The modern process is named after its inventor, the Englishman Henry Bessemer, who took out a patent on the process in 1856. The process was said to be independently discovered in 1851 by the American inventor William Kelly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dieselization
Dieselisation (US: dieselization) is the process of equipping vehicles with a diesel engine or diesel engines. It can involve replacing an internal combustion engine powered by petrol (gasoline) fuel with an engine powered by diesel fuel, as occurred on a large scale with trucks, buses, farm tractors, and building construction machinery after the Second World War. Alternatively it can involve replacing the entire plant or vehicle with one that is diesel-powered; the term commonly describes the generational replacement between the 1930s and the 1970s of railway steam locomotives with diesel locomotives, and associated facilities. Water transport The Two-stroke diesel engine for marine applications was introduced in 1908 and remains in use today. It is the most efficient prime mover to date, models such as the Wärtsilä-Sulzer RTA96-C offer a thermal efficiency of 50% and over 100,000 horsepowers. First steps towards conversions using diesel engines as means of propulsion (on sm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diesel Locomotive
A diesel locomotive is a type of railway locomotive in which the prime mover is a diesel engine. Several types of diesel locomotives have been developed, differing mainly in the means by which mechanical power is conveyed to the driving wheels. Early internal combustion locomotives and railcars used kerosene and gasoline as their fuel. Rudolf Diesel patented his first compression-ignition engine in 1898, and steady improvements to the design of diesel engines reduced their physical size and improved their power-to-weight ratios to a point where one could be mounted in a locomotive. Internal combustion engines only operate efficiently within a limited power band, and while low power gasoline engines could be coupled to mechanical transmissions, the more powerful diesel engines required the development of new forms of transmission. This is because clutches would need to be very large at these power levels and would not fit in a standard -wide locomotive frame, or wear too quic ...

Alco
The American Locomotive Company (often shortened to ALCO, ALCo or Alco) was an American manufacturer of locomotives, diesel generators, steel, and tanks that operated from 1901 to 1969. The company was formed by the merger of seven smaller locomotive manufacturers and Schenectady Locomotive Engine Manufactory of Schenectady, New York. A subsidiary, American Locomotive Automobile Company, designed and manufactured automobiles under the Alco brand from 1905 to 1913. ALCO also produced nuclear reactors from 1954 to 1962. The company changed its name to Alco Products, Incorporated in 1955. In 1964, the Worthington Corporation acquired the company. The company went out of business in 1969. The ALCO name is currently being used by Fairbanks Morse Engine for their FM, ALCO line.

Monongahela Railway
The Monongahela Railway was a coal-hauling short line railroad in Pennsylvania and West Virginia in the United States. It was jointly controlled originally by the Pennsylvania Railroad, New York Central subsidiary Pittsburgh and Lake Erie Railroad, and the Baltimore and Ohio Railroad, with NYC and PRR later succeeded by Penn Central Transportation. The company operated its own line until it was merged into Conrail on May 1, 1993. The primary connection to both controlling systems was at Brownsville, Pennsylvania - with the south end of the P&LE's Pittsburgh, McKeesport and Youghiogheny Railroad and with the PRR's ex- Brownsville Railway. The PRR also interchanged traffic at Hoover, Pennsylvania, the end of its Coal Lick Run Branch. The B&O Railroad interchanged at Leckrone, Pennsylvania, and Rivesville, West Virginia. At the end of 1970 it operated 193 miles of road on 281 miles of track; that year it reported 446 million ton-miles of revenue freight. History The Mono ...
