Allegheny Portage Railroad National Historic Site
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. T ...

Ridge
A ridge or a mountain ridge is a geographical feature consisting of a chain of mountains or hills that form a continuous elevated crest for an extended distance. The sides of the ridge slope away from the narrow top on either side. The lines along the crest formed by the highest points, with the terrain dropping down on either side, are called the ridgelines. Ridges are usually termed hills or mountains as well, depending on size. Smaller ridges, especially those leaving a larger ridge, are often referred to as spurs. Types There are several main types of ridges: ;Dendritic ridge: In typical dissected plateau terrain, the stream drainage valleys will leave intervening ridges. These are by far the most common ridges. These ridges usually represent slightly more erosion resistant rock, but not always – they often remain because there were more joints where the valleys formed or other chance occurrences. This type of ridge is generally somewhat random in orientation, often ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Staple Bend Tunnel
The Staple Bend Tunnel, about east of Johnstown, Pennsylvania, in a town called Mineral Point, was constructed between 1831 and 1834 for the Allegheny Portage Railroad. Construction began on April 12, 1831. This tunnel, at in length, was the first railway tunnel constructed in the United States. It is rock-bored and stone-lined. Finished in June 1833, the Staple Bend Tunnel was advertised as the first railroad tunnel in the United States. It was the third tunnel of any kind built in the U.S.; the first two tunnels were for canals in Pennsylvania. History Work began on November 21, 1831, and often occurred during inclement conditions. The men were paid $13 per month plus room and board for 12-hour days, 6 days per week. Workers chipped and blasted of solid rock to make the tunnel. Approximately of bedrock was removed using black powder blasting. This was done by drilling -long holes and packing them with powder. Drilling one typical hole took up to three hours of hard effor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oldest Railroads In North America
This is a list of the earliest railroads in North America, including various railroad-like precursors to the general modern form of a company or government agency operating locomotive-drawn trains on metal tracks. Railroad-like entities (1700s–1810s) *1720: A railroad was reportedly used in the construction of the French fortress at Louisburg, Nova Scotia, Canada. *1764: Between 1762 and 1764, at the close of the French and Indian War, a gravity railroad ( mechanized tramway) ( Montresor's Tramway) was built by British military engineers up the steep riverside terrain near the Niagara River waterfall's escarpment at the Niagara Portage (which the local Senecas called ''"Crawl on All Fours."'') in Lewiston, New York.Text online of placement commemoratin ...

Appalachian Mountains
The Appalachian Mountains, often called the Appalachians, (french: Appalaches), are a system of mountains in eastern to northeastern North America. The Appalachians first formed roughly 480 million years ago during the Ordovician Period. They once reached elevations similar to those of the Alps and the Rocky Mountains before experiencing natural erosion. The Appalachian chain is a barrier to east–west travel, as it forms a series of alternating ridgelines and valleys oriented in opposition to most highways and railroads running east–west. Definitions vary on the precise boundaries of the Appalachians. The United States Geological Survey (USGS) defines the ''Appalachian Highlands'' physiographic division as consisting of 13 provinces: the Atlantic Coast Uplands, Eastern Newfoundland Atlantic, Maritime Acadian Highlands, Maritime Plain, Notre Dame and Mégantic Mountains, Western Newfoundland Mountains, Piedmont, Blue Ridge, Valley and Ridge, St. Lawrence Valley, Appalac ...

Ski Lift
A ski lift is a mechanism for transporting skiers up a hill. Ski lifts are typically a paid service at ski resorts. The first ski lift was built in 1908 by German Robert Winterhalder in Schollach/Eisenbach, Hochschwarzwald. Types * Aerial lifts transport skiers while suspended off the ground. Aerial lifts are often bicable ropeways, the "bi-" prefix meaning that the cables have two different functions (carrying and pulling). **Aerial tramways ** Chairlifts and detachable chairlifts ** Funifors ** Funitels ** Gondola lifts ** Hybrid lifts * Surface lifts, including T-bars, magic carpets, and rope tows. * Cable railways, including funiculars * Helicopters are used for heliskiing and snowcats for snowcat skiing. This is backcountry skiing or boarding accessed by a snowcat or helicopter instead of a lift, or by hiking. Cat skiing is less than half the cost of heliskiing, more expensive than a lift ticket but is easier than ski touring. Cat skiing is guided. Skiing at select, ...

Inclined Planes
An inclined plane, also known as a ramp, is a flat supporting surface tilted at an angle from the vertical direction, with one end higher than the other, used as an aid for raising or lowering a load. The inclined plane is one of the six classical simple machines defined by Renaissance scientists. Inclined planes are used to move heavy loads over vertical obstacles. Examples vary from a ramp used to load goods into a truck, to a person walking up a pedestrian ramp, to an automobile or railroad train climbing a grade. Moving an object up an inclined plane requires less force than lifting it straight up, at a cost of an increase in the distance moved. The mechanical advantage of an inclined plane, the factor by which the force is reduced, is equal to the ratio of the length of the sloped surface to the height it spans. Owing to conservation of energy, the same amount of mechanical energy (work) is required to lift a given object by a given vertical distance, disregarding losses ...

Animal Power
A working animal is an animal, usually domesticated, that is kept by humans and trained to perform tasks instead of being slaughtered to harvest animal products. Some are used for their physical strength (e.g. oxen and draft horses) or for transportation (e.g. riding horses and camels), while others are service animals trained to execute certain specialized tasks (e.g. hunting and guide dogs, messenger pigeons and fishing cormorants). They may also be used for milking or herding. Some, at the end of their working lives, may also be used for meat or other products such as leather. The history of working animals may predate agriculture, with dogs used by our hunter-gatherer ancestors. Around the world, millions of animals work in relationship with their owners. Domesticated species are often bred for different uses and conditions, especially horses and working dogs. Working animals are usually raised on farms, though some are still captured from the wild, such as dolphins and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
