Board Tree Tunnel
The Board Tree Tunnel, near Littleton, West Virginia, was built between 1851 and 1858 by the Baltimore and Ohio Railroad on its main line between Baltimore, Maryland, and Wheeling, West Virginia, under the supervision of B&O chief engineer Benjamin Henry Latrobe, II. The tunnel used a segmental cast iron lining system pioneered on the contemporaneous Kingwood Tunnel on the same line. Workers were recruited from coal mines in the area to excavate the tunnel. The tunneling operations used black powder as explosive. About 30 deaths and 300 injuries occurred in the excavation of the Board Tree and Kingwood tunnels. The tunnel is now abandoned.

Baltimore And Ohio Railroad
The Baltimore and Ohio Railroad was the first common carrier railroad and the oldest railroad in the United States, with its first section opening in 1830. Merchants from Baltimore, which had benefited to some extent from the construction of the National Road early in the century, wanted to do business with settlers crossing the Appalachian Mountains. The railroad faced competition from several existing and proposed enterprises, including the Albany-Schenectady Turnpike, built in 1797, the Erie Canal, which opened in 1825, and the Chesapeake and Ohio Canal. At first, the B&O was located entirely in the state of Maryland; its original line extending from the port of Baltimore west to Sandy Hook, Maryland, opened in 1834. There it connected with Harper's Ferry, first by boat, then by the Wager Bridge, across the Potomac River into Virginia, and also with the navigable Shenandoah River. Because of competition with the C&O Canal for trade with coal fields in western Maryland, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Benjamin Henry Latrobe, II
Benjamin Henry Latrobe II (December 19, 1806 – October 19, 1878) was an American civil engineer, best known for his railway bridges, and a railway executive. Personal life Born in Philadelphia, Pennsylvania on December 19, 1806, he was the youngest son of Benjamin Henry Latrobe who six years previously had married his second wife, Mary Elizabeth Hazlehurst (1771–1841) of Philadelphia. Three years earlier, President Thomas Jefferson hired his father as Surveyor of Public Buildings in the new national capitol, Washington, D.C. His father became best known as the second Architect of the Capitol, because he redesigned the rebuilt United States Capitol after the British Army burned Washington in August 1814 during the War of 1812. The senior Latrobe also designed and supervised construction of the first Roman Catholic cathedral built in the United States, the old Baltimore Cathedral (later named the Basilica of the Assumption of Mary), 1806–1821, as well as construct ...

Kingwood Tunnel
The Kingwood Tunnel, near Tunnelton, West Virginia, was built between 1849 and 1852 by the Baltimore and Ohio Railroad on its main line between Baltimore, Maryland and Wheeling, West Virginia, under the supervision of B&O chief engineer Benjamin Henry Latrobe, II. At the time of its completion the tunnel was the longest tunnel in the United States until it was surpassed by the Blue Ridge Tunnel in 1858. Workers were recruited from coal mines in the area to excavate the tunnel. Three vertical shafts were established to allow work in two directions from each shaft, and from either end, using eight headings. The shafts were about deep and measured about by . The hoists were operated using horses. The tunneling operations used black powder Gunpowder, also commonly known as black powder to distinguish it from modern smokeless powder, is the earliest known chemical explosive.

Black Powder
Gunpowder, also commonly known as black powder to distinguish it from modern smokeless powder, is the earliest known chemical explosive. It consists of a mixture of sulfur, carbon (in the form of charcoal) and potassium nitrate (saltpeter). The sulfur and carbon act as fuels while the saltpeter is an oxidizer. Gunpowder has been widely used as a propellant in firearms, artillery, rocketry, and pyrotechnics, including use as a blasting agent for explosives in quarrying, mining, building pipelines and road building. Gunpowder is classified as a low explosive because of its relatively slow decomposition rate and consequently low brisance. Low explosives deflagrate (i.e., burn at subsonic speeds), whereas high explosives detonate, producing a supersonic shockwave. Ignition of gunpowder packed behind a projectile generates enough pressure to force the shot from the muzzle at high speed, but usually not enough force to rupture the gun barrel. It thus makes a good propellant but is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Buildings And Structures In Marshall County, West Virginia
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful). Ever since the first cave paintings, buildings have also become objects or canvasses of much artis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Historic American Engineering Record In West Virginia
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 ...

Tunnels Completed In 1858
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 saf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
