New Portage Tunnel
The Gallitzin Tunnels in Gallitzin, Pennsylvania, are a set of three adjacent tunnels through the Allegheny Mountains in western Pennsylvania. They were completed in 1854, 1855, and 1902 by the Pennsylvania Railroad as part of the cross-state route that includes the nearby Horseshoe Curve to the east. Their ownership has since passed to Penn Central Transportation Company, then to Conrail, and most recently to the Norfolk Southern Railway. The tunnels are currently used by Norfolk Southern freight trains and Amtrak ''Pennsylvanian'' passenger trains. History Construction The first tunnel, which is the middle of the three bores through the mountain, was built by the PRR from 1851 to 1854. Originally named "Summit" Tunnel, it is 3,612 feet long at an elevation of 2,167 feet above mean sea level and is known today as the Allegheny Tunnel. The second tunnel, the southernmost of the bores, was constructed by the Commonwealth of Pennsylvania from 1852 to 1855 as part of the New Po ...

Conrail
Conrail , formally the Consolidated Rail Corporation, was the primary Class I railroad in the Northeastern United States between 1976 and 1999. The trade name Conrail is a portmanteau based on the company's legal name. It continues to do business as an asset management and network services provider in three Shared Assets Areas that were excluded from the division of its operations during its acquisition by CSX Corporation and the Norfolk Southern Railway. The federal government created Conrail to take over the potentially-profitable lines of multiple bankrupt carriers, including the Penn Central Transportation Company and Erie Lackawanna Railway. After railroad regulations were lifted by the 4R Act and the Staggers Act, Conrail began to turn a profit in the 1980s and was privatized in 1987. The two remaining Class I railroads in the East, CSX Transportation and the Norfolk Southern Railway (NS), agreed in 1997 to acquire the system and split it into two roughly-equal parts (a ...

Pennsylvanian (train)
The ''Pennsylvanian'' is a daily daytime Amtrak train running between New York and Pittsburgh via Philadelphia. The trains travel across the Appalachian Mountains, through Pennsylvania's capital Harrisburg, the Pennsylvania Dutch Country, suburban and central Philadelphia, and New Jersey en route to New York. The entire train ride takes about 9 hours total: 1.5 hours between New York and Philadelphia, 2 hours between Philadelphia and Harrisburg, and 5.5 hours between Harrisburg and Pittsburgh. The ''Pennsylvanian'' uses the same Amtrak-owned Philadelphia to Harrisburg Main Line as the '' Keystone Service'' trains, but continues further west via the Pittsburgh Line through Altoona and the Allegheny Mountains, eventually terminating its run in Pittsburgh. The Main Line and Pittsburgh Line collectively make up the Keystone Corridor, a federally-designated corridor for high-speed rail service. History Prior to Amtrak, the ''Pennsylvanian'' route was covered by the ''Duquesne'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Historic American Engineering Record In Pennsylvania
History (derived ) is the systematic study and the documentation of the human activity. The time period of event before the invention of writing systems is considered prehistory. "History" is an umbrella term comprising past events as well as the memory, discovery, collection, organization, presentation, and interpretation of these events. Historians seek knowledge of the past using historical sources such as written documents, oral accounts, art and material artifacts, and ecological markers. History is not complete and still has debatable mysteries. History is also an academic discipline which uses narrative to describe, examine, question, and analyze past events, and investigate their patterns of cause and effect. Historians often debate which narrative best explains an event, as well as the significance of different causes and effects. Historians also debate the nature of history as an end in itself, as well as its usefulness to give perspective on the problems of the p ...

Transportation Buildings And Structures In Cambria County, Pennsylvania
Transport (in British English), or transportation (in American English), is the intentional movement of humans, animals, and goods from one location to another. Modes of transport include air, land (rail and road), water, cable, pipeline, and space. The field can be divided into infrastructure, vehicles, and operations. Transport enables human trade, which is essential for the development of civilizations. Transport infrastructure consists of both fixed installations, including roads, railways, airways, waterways, canals, and pipelines, and terminals such as airports, railway stations, bus stations, warehouses, trucking terminals, refueling depots (including fueling docks and fuel stations), and seaports. Terminals may be used both for interchange of passengers and cargo and for maintenance. Means of transport are any of the different kinds of transport facilities used to carry people or cargo. They may include vehicles, riding animals, and pack animals. Vehicles may inclu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Norfolk Southern Railway Tunnels
Norfolk () is a ceremonial and non-metropolitan county in East Anglia in England. It borders Lincolnshire to the north-west, Cambridgeshire to the west and south-west, and Suffolk to the south. Its northern and eastern boundaries are the North Sea, with The Wash to the north-west. The county town is the city of Norwich. With an area of and a population of 859,400, Norfolk is a largely rural county with a population density of 401 per square mile (155 per km2). Of the county's population, 40% live in four major built up areas: Norwich (213,000), Great Yarmouth (63,000), King's Lynn (46,000) and Thetford (25,000). The Broads is a network of rivers and lakes in the east of the county, extending south into Suffolk. The area is protected by the Broads Authority and has similar status to a national park. History The area that was to become Norfolk was settled in pre-Roman times, (there were Palaeolithic settlers as early as 950,000 years ago) with camps along the higher lan ...

Railroad Tunnels 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 facil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Double-stack Rail Transport
Double-stack rail transport is a form of intermodal freight transport in which railroad cars carry two layers of intermodal containers. Invented in the United States in 1984, it is now being used for nearly seventy percent of United States intermodal shipments. Using double stack technology, a freight train of a given length can carry roughly twice as many containers, sharply reducing transport costs per container. On United States railroads special well cars are used for double-stack shipment to reduce the needed vertical clearance and to lower the center of gravity of a loaded car. In addition, the well car design reduces damage in transit and provides greater cargo security by cradling the lower containers so their doors cannot be opened. A succession of larger container sizes have been introduced to further increase shipping productivity in the United States. Double-stack rail operations are growing in other parts of the world, but are often constrained by clearance and ot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gallitzin, Pennsylvania
Gallitzin is a borough in Cambria County, Pennsylvania, in the United States. It is bordered by Gallitzin Township and Tunnelhill, all of which sit astride the Eastern continental divide. Tunnel Hill and Gallitzin both are pierced by railroad tunnels shortening the necessary ascent for rails crossing the Allegheny Front onto the Allegheny Plateau which encompasses the towns' terrains. Topping the gaps of the Allegheny, the area is one of only five major breaks in the Appalachians allowing east–west transportation corridors before the advent of 20th century technologies. History Dutch traders and trappers friendly to the Susquehannock may have visited the region about 1620, as the town sits atop a mountain pass through which the ancient Amerindian trails (later renamed the Kittanning Path) transited. The plateau atop the escarpment was the domain of the Iroquoian confederations of the Erie people and the Susquehannock peoples, both sharing the byways and hunting lands of the ...

Allegheny Portage Railroad
The Allegheny Portage Railroad was the first railroad constructed through the Allegheny Mountains in central Pennsylvania, United States; it operated from 1834 to 1854 as the first transportation infrastructure through the gaps of the Allegheny that connected the midwest to the eastern seaboard across the barrier range of the Allegheny Front. Approximately long overall, both ends connected to the Pennsylvania Canal, and the system was primarily used as a portage railway, hauling river boats and barges over the divide between the Ohio and the Susquehanna Rivers. Today, the remains of the railroad are preserved within the Allegheny Portage Railroad National Historic Site operated by the National Park Service. The railroad was authorized as part of the Main Line of Public Works legislation in 1824. It had five inclines on either side of the drainage divide running athwart the ridge line from Blair Gap through along the kinked saddle at the summit into Cresson, Pennsylvania. The ...

Penn Central
The Penn Central Transportation Company, commonly abbreviated to Penn Central, was an American Railroad classes, class I railroad that operated from 1968 to 1976. Penn Central combined three traditional corporate rivals (the Pennsylvania Railroad, Pennsylvania, New York Central Railroad, New York Central and the New York, New Haven and Hartford Railroad, New York, New Haven and Hartford railroads), all united by heavy service into the New York metropolitan area and (to a lesser extent) New England and Chicago. The new company failed barely two years after formation, the largest bankruptcy in U.S. history at the time. The Penn Central's railroad assets were nationalized into Conrail along with the other bankrupt northeastern roads; its real estate and insurance holdings successfully Reorganization, reorganized into American Premier Underwriters.
