Logans Ferry Mine Tunnel
The Logans Ferry Mine Tunnel consists of a pair of abandoned coal tunnels under the Allegheny River between Plum and Springdale, Pennsylvania in the United States. History In 1919, West Penn Power acquired the land to build a power facility in Springdale, but did not have an adequate coal source. As a result, they leased coal-rich land on the opposite shore of the river. To simplify transport issues, the decision was made to build the mine tunnel, which opened in 1921. By the 1940s, the mine's resources started to be depleted and West Penn, which had constructed the neighborhood of Logan Heights (which today looks unlike most of the 1960s-or-later suburban stock that dominates Plum), transformed from being a company town to a community of homeowners. In 1954, the mine transferred most of its operations east to Upper Burrell Upper Burrell Township is a township in Westmoreland County, Pennsylvania, United States, within the Pittsburgh metropolitan area.

Allegheny River
The Allegheny River ( ) is a long headwater stream of the Ohio River in western Pennsylvania and New York. The Allegheny River runs from its headwaters just below the middle of Pennsylvania's northern border northwesterly into New York then in a zigzag southwesterly across the border and through Western Pennsylvania to join the Monongahela River at the Forks of the Ohio on the "Point" of Point State Park in Downtown Pittsburgh, Pennsylvania. The Allegheny River is, by volume, the main headstream of both the Ohio and Mississippi Rivers. Historically, the Allegheny was considered to be the upper Ohio River by both Native Americans and European settlers. The shallow river has been made navigable upstream from Pittsburgh to East Brady by a series of locks and dams constructed in the early 20th century. A 24-mile long portion of the upper river in Warren and McKean counties of Pennsylvania and Cattaraugus County in New York is the Allegheny Reservoir, created by the erect ...

Bessemer And Lake Erie Railroad
The Bessemer and Lake Erie Railroad is a class II railroad that operates in northwestern Pennsylvania and northeastern Ohio. The railroad's main route runs from the Lake Erie port of Conneaut, Ohio, to the Pittsburgh suburb of Penn Hills, Pennsylvania, a distance of . The original rail ancestor of the B&LE, the Shenango and Allegheny Railroad, began operation in October 1869. Rail operations were maintained continuously by various corporate descendants on the growing system that ultimately became the BLE in 1900. In 2004 BLE came under the ownership of the Canadian National Railway (CN) as part of CN's larger purchase of holding company Great Lakes Transportation. BLE is operated by CN as their Bessemer Subdivision. As a subsidiary of CN, BLE has been largely unchanged (though repainting of BLE locomotives into CN paint with "BLE" sub-lettering began in April 2015) and still does business as BLE. BLE locomotives, especially the former Southern Pacific SD40T-3 "Tunnel Motors", ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mining In Pennsylvania
Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef, or placer deposit. The exploitation of these deposits for raw material is based on the economic viability of investing in the equipment, labor, and energy required to extract, refine and transport the materials found at the mine to manufacturers who can use the material. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay. Mining is required to obtain most materials that cannot be grown through agricultural processes, or feasibly created artificially in a laboratory or factory. Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even water. Modern mining processes involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desired materials, and ...

Tunnels In Allegheny County, Pennsylvania
A tunnel is an underground passageway, dug through surrounding soil, earth or rock, and enclosed except for the entrance and exit, commonly at each end. A pipeline is not a tunnel, though some recent tunnels have used immersed tube construction techniques rather than traditional tunnel boring methods. A tunnel may be for foot or vehicular road traffic, for rail traffic, or for a canal. The central portions of a rapid transit network are usually in the tunnel. Some tunnels are used as sewers or aqueducts to supply water for consumption or for hydroelectric stations. Utility tunnels are used for routing steam, chilled water, electrical power or telecommunication cables, as well as connecting buildings for convenient passage of people and equipment. Secret tunnels are built for military purposes, or by civilians for smuggling of weapons, contraband, or people. Special tunnels, such as wildlife crossings, are built to allow wildlife to cross human-made barriers safely. Tunne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Upper Burrell Township, Westmoreland County, Pennsylvania
Upper Burrell Township is a township in Westmoreland County, Pennsylvania, United States, within the Pittsburgh metropolitan area. The population was 2,159 at the 2020 census.
