Troy Hill Incline
The Troy Hill Incline, also known as the Mount Troy Incline, was a funicular railway located in old Allegheny, Pennsylvania, which is now the North Side of the city of Pittsburgh. History and notable features Built by Gustav Lindenthal or Samuel Diescher, the incline was one of only a few funiculars constructed on the north side of Pittsburgh. It began construction in August 1887, and after considerable delay, opened on September 20, 1888. The incline ascended from Ohio Street near the end of the second 30th Street Bridge to Lowrie Street on the crest of Troy Hill. Never very profitable, it shut down in fall 1898 and was razed a decade later. A building now standing at 1733 Lowrie Street was long thought to have been the summit station, but later research found that the building did not appear on maps until well after the incline closed. The incline's length measured , with a forty-seven percent (47 %) gradient. The cost of construction was about $94,047. See also * List ...

Grade (slope)
The grade (also called slope, incline, gradient, mainfall, pitch or rise) of a physical feature, landform or constructed line refers to the tangent of the angle of that surface to the horizontal. It is a special case of the slope, where zero indicates horizontality. A larger number indicates higher or steeper degree of "tilt". Often slope is calculated as a ratio of "rise" to "run", or as a fraction ("rise over run") in which ''run'' is the horizontal distance (not the distance along the slope) and ''rise'' is the vertical distance. Slopes of existing physical features such as canyons and hillsides, stream and river banks and beds are often described as grades, but typically grades are used for human-made surfaces such as roads, landscape grading, roof pitches, railroads, aqueducts, and pedestrian or bicycle routes. The grade may refer to the longitudinal slope or the perpendicular cross slope. Nomenclature There are several ways to express slope: # as an ''angle'' of inc ...

Pittsburgh is located in southwest Pennsylvania at the confluence of the Allegheny River and the Monongahela River, which combine to form the Ohio River. Pittsburgh is known both as "the Steel City" for its more than 300 steel-related businesses and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Railway Lines Opened In 1888
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 facilit ...

List Of Inclines In Pittsburgh
Beginning in 1870, the city of Pittsburgh, Pennsylvania built numerous inclined railways to provide passenger service to workers traveling the steep hills to their homes; there were 17 built in the late 19th century. Following road building and greater use of private automobiles, the inclines business declined and most were closed and removed. The Monongahela Incline, the first built in the city, and the Duquesne Incline are the only two still operating. They carry passengers between Mount Washington and the lowlands along the Monongahela River. They are each listed on the National Register of Historic Places and, in 1977, both were recognized as Historic Mechanical Engineering Landmarks by the American Society of Mechanical Engineers The American Society of Mechanical Engineers (ASME) is an American professional association that, in its own words, "promotes the art, science, and practice of multidisciplinary engineering and allied sciences around the globe" via "continuing ...

List Of Funicular Railways
This is a list of funicular railways, organised by place within country and continent. The funiculars range from short urban lines to significant multi-section mountain railways. A funicular railway is distinguished from the similar incline elevator in that it has two vehicles that counterbalance one another rather than independently operated cars.

Troy Hill (Pittsburgh)
Troy Hill is a neighborhood on Pittsburgh, Pennsylvania's North Side. It has a zip code of 15212, and has representation on Pittsburgh City Council by the council member for District 1. Troy Hill sits on a plateau above the Allegheny River. It is approximately long from Vinial Street to the end of Lowrie Street and only wide from Wicklines Lane to Herrs Island. History Troy Hill was originally part of the Reserve Tract laid out by surveyor and Pennsylvania Vice-President David Redick in 1788. Incorporated in 1833 as the village of New Troy, it was settled by German immigrants who worked in the mills, tanneries, breweries, and railroads that lined the Allegheny River. The migration up to Troy Hill began when a Catholic church opened a small cemetery in 1842. By 1866 one hundred families were officially Troy Hill residents. The adjacent riverfront land along with Herr's Island would in 1849 be incorporated into the short-lived Duquesne borough (distinct from the modern boro ...

Funicular
A funicular (, , ) is a type of cable railway system that connects points along a railway track laid on a steep slope. The system is characterized by two counterbalanced carriages (also called cars or trains) permanently attached to opposite ends of a haulage cable, which is looped over a pulley at the upper end of the track. The result of such a configuration is that the two carriages move synchronously: as one ascends, the other descends at an equal speed. This feature distinguishes funiculars from inclined elevators, which have a single car that is hauled uphill. The term ''funicular'' derives from the Latin word , the diminutive of , meaning 'rope'. Operation In a funicular, both cars are permanently connected to the opposite ends of the same cable, known as a ''haul rope''; this haul rope runs through a system of pulleys at the upper end of the line. If the railway track is not perfectly straight, the cable is guided along the track using sheaves – unpowered pulleys tha ...

30th Street Bridge
The 30th Street Bridge, is a girder bridge that carries vehicular traffic across the Allegheny River between the Pittsburgh neighborhoods of Troy Hill and Herrs Island (known by the moniker of Washington's Landing). This is the fourth bridge that has stood on this site. A wooden 19th Century bridge was washed away during an 1882 flood. This was replaced by an arch bridge that spanned the entire width of the Allegheny River; after a 1921 fire destroyed the span across the main channel, the 31st Street Bridge was constructed as a replacement, and this bridge was again relegated to taking traffic to Herrs Island. A 1939 truss bridge then stood on this site, and it was replaced by the current structure as part of the redevelopment of the island to feature condominiums and a business park instead of warehouses and stockyards.

Samuel Diescher
Samuel Diescher (June 25, 1839 – December 24, 1915) was a prominent Hungarian-American civil and mechanical engineer who had his career in the United States. After being educated at universities in Karlsruhe and Zurich in Europe, he immigrated to the United States in 1866 and settled in Cincinnati, Ohio. There he supervised construction of his first inclined plane. He later moved to Pittsburgh, Pennsylvania, where he worked with John Endres on the Monongahela Incline (1870), the first passenger incline in the city. Diescher designed the Duquesne Incline (1877). He is believed to have designed the majority of inclined planes in the United States, including numerous projects in Pennsylvania. He also designed a wide range of industrial projects, particularly those related to the coal and steel industries. His three sons also became engineers and in 1901 he set up a business with them: S. Diescher and Sons. These two early inclines in Pittsburgh are the only passenger inclines sti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
