Union Railroad (Pittsburgh, Pennsylvania)
The Union Railroad is a Class III switching railroad located in Allegheny County in Western Pennsylvania. The company is owned by Transtar, Inc., which is itself a subsidiary of Fortress Transportation and Infrastructure Investors, after being purchased from United States Steel in 1988. The railroad's primary customers are the three plants of the USS Mon Valley Works, the USS Edgar Thomson Steel Works (blast furnaces, basic oxygen steelmaking, and continuous slab casting), the USS Irvin Works (hot and cold rolling mills and finishing lines) and the USS Clairton Works (producer of coke for blast furnace ironmaking). History Andrew Carnegie had been discussing rail transport with other lines, but determined the best way to protect his interests was to control the rail line himself. Several smaller companies had constructed sections of the route. "Bear Creek Railroad (name changed to Shenango and Allegheny Railroad Co.) was incorporated in March 1865 for the purpose of moving c ...

PRR Port Perry Bridge
The PPR Port Perry Bridge is a truss bridge that carries the Port Perry Branch of the Norfolk Southern Railway across the Monongahela River between the Pennsylvania towns of North Versailles Township, and Duquesne. The bridge was built to serve the Pennsylvania Railroad, to provide better access to industrial sites, and to help through trains bypass downtown Pittsburgh. Today, the bridge and corresponding route serve a similar purpose and are used to allow high-level loads, especially double-stacked container cars, to avoid the narrower routes through Pittsburgh.

Metal Bridges In The United States
A metal (from Greek μέταλλον ''métallon'', "mine, quarry, metal") is a material that, when freshly prepared, polished, or fractured, shows a lustrous appearance, and conducts electricity and heat relatively well. Metals are typically ductile (can be drawn into wires) and malleable (they can be hammered into thin sheets). These properties are the result of the ''metallic bond'' between the atoms or molecules of the metal. A metal may be a chemical element such as iron; an alloy such as stainless steel; or a molecular compound such as polymeric sulfur nitride. In physics, a metal is generally regarded as any substance capable of conducting electricity at a temperature of absolute zero. Many elements and compounds that are not normally classified as metals become metallic under high pressures. For example, the nonmetal iodine gradually becomes a metal at a pressure of between 40 and 170 thousand times atmospheric pressure. Equally, some materials regarded as metals ca ...

Bridges In Allegheny County, Pennsylvania
A bridge is a structure built to span a physical obstacle (such as a body of water, valley, road, or rail) without blocking the way underneath. It is constructed for the purpose of providing passage over the obstacle, which is usually something that is otherwise difficult or impossible to cross. There are many different designs of bridges, each serving a particular purpose and applicable to different situations. Designs of bridges vary depending on factors such as the function of the bridge, the nature of the terrain where the bridge is constructed and anchored, and the material used to make it, and the funds available to build it. The earliest bridges were likely made with fallen trees and stepping stones. The Neolithic people built boardwalk bridges across marshland. The Arkadiko Bridge (dating from the 13th century BC, in the Peloponnese) is one of the oldest arch bridges still in existence and use. Etymology The ''Oxford English Dictionary'' traces the origin of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Railroad Bridges In Pennsylvania
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 faci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rankin Bridge
The George Rankin Jr. Memorial Bridge is a cantilever bridge that carries the Green Belt across the Monongahela River between Whitaker and Rankin in Pennsylvania in the USA. It carries four lanes of automobile traffic, plus pedestrian walkways, both paved with concrete. The bridge carries over 22,500 people per day. The bridge and many of its approach ramps were originally built with tram tracks, all of which have since been removed. History The Rankin Bridge was built on the site of the 1897 steel truss West Braddock Bridge, a narrow trolley bridge equipped with a wooden deck. Like similar road-rail bridges in the area, the West Braddock Bridge was poorly suited to automobile and truck traffic, a deficiency the new bridge rectified. The Rankin Bridge was first and foremost an automobile bridge, but it also accommodated streetcars with equal facility as it carried Pittsburgh Railways trolley route #55 ''Homestead- East Pittsburgh'' on both the main span (the middle two traff ...

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 ...

Edgar Thomson Steel Works
The Edgar Thomson Steel Works is a steel mill in the Pittsburgh area communities of Braddock and North Braddock, Pennsylvania, United States. It has been active since 1875. It is currently owned by U.S. Steel and is known as Mon Valley Works – Edgar Thomson Plant on its official website. History The mill occupies the historic site of Braddock's Field, on the banks of the Monongahela River east of Pittsburgh. On July 9, 1755, in the Battle of the Monongahela, French and Indian forces from Fort Duquesne defeated the expedition of British General Edward Braddock, who himself was mortally wounded. Braddock's Field was also the site of a rally of rebellious militiamen and farmers during the Whiskey Rebellion, prior to a massive march on the town of Pittsburgh on August 1, 1794."The Planting of Civilization in Western Pennsylvania, Buck, Solon J.

Port Perry, Pennsylvania
Port Perry was a town along the Monongahela River near Braddock, Pennsylvania and by the mouth of Turtle Creek. It disappeared by 1945, having been gradually replaced by railroad tracks serving the nearby Edgar Thomson Steel Works. History The town was laid out in the 1790s by its founder, John Perry. On June 1, 1795, Perry advertised his "new town", citing its proximity to roads, mills and quarries, and claiming its harbor was "the best on the western waters." Zadok Cramer's ''The Navigator'' (1802) referred to the settlement as Perrystown. A later edition of the ''Navigator'' stated that the town by the mouth of Turtle Creek had "not progressed". Only eight families reportedly resided there in 1840. It was not until some fifty years after its founding that Port Perry began to develop in earnest. The original Monongahela Lock and Dam No. 2 was built beside it and opened in 1841. The town was resurveyed and replatted by Col. William L. Miller, who lived on the adjacent hill. M ...
