Castle Shannon Incline
The Castle Shannon Incline was a funicular railroad in Pittsburgh, Pennsylvania. It was originally part of the Pittsburgh and Castle Shannon Railroad route to the suburb of Castle Shannon. It replaced an earlier incline dating to 1825 that brought coal down from a mine in Mount Washington. History Initially opened on August 26, 1890, the incline operated for only a few days before breaking down, the original machinery being unable to bear the strain of the large freight and passenger cars. After a second abortive run in October, it was decided that the machinery had to be replaced. The refitted incline opened on March 7, 1891. It ran from Bailey Avenue west of Haberman Avenue down to Carson Street just west of Arlington Avenue. The oldest part of the Pittsburgh and Castle Shannon Railroad was a coal mine in Mount Washington. When the mine was played out in 1861, the company opened the back (south) side of the mine and continued it down a horseshoe curve into the Saw Mill Run ...

Mount Washington, Pittsburgh (mountain)
Mount Washington is a hill in Pittsburgh, on the southern banks of the Monongahela River and Ohio River. History In the early history of Pittsburgh, Mount Washington was known as Coal Hill, but Coal Hill was actually on the south bank of the Monongahela River. Easy access to the Pittsburgh coal seam's outcrop near the base of Mount Washington allowed several mines to operate there. Also, rock was quarried from the hill. Gray sandstone, for example, was quarried at Coal Hill for the second Allegheny County Courthouse. By 1876, the name had been changed to Mount Washington, and a year later, the view of the City of Pittsburgh was first drawn from Mount Washington. Many photos of the Pittsburgh skyline are from Mount Washington, due to the elevation of the hill overlooking the river valley and Downtown Pittsburgh below. Inclines The original switchback trails that wound up the steep slopes of Mount Washington were barely passable to a team of horses pulling a loaded wagon. ...

Steam Power
A steam engine is a heat engine that performs mechanical work using steam as its working fluid. The steam engine uses the force produced by steam pressure to push a piston back and forth inside a cylinder. This pushing force can be transformed, by a connecting rod and crank, into rotational force for work. The term "steam engine" is generally applied only to reciprocating engines as just described, not to the steam turbine. Steam engines are external combustion engines, where the working fluid is separated from the combustion products. The ideal thermodynamic cycle used to analyze this process is called the Rankine cycle. In general usage, the term ''steam engine'' can refer to either complete steam plants (including boilers etc.), such as railway steam locomotives and portable engines, or may refer to the piston or turbine machinery alone, as in the beam engine and stationary steam engine. Although steam-driven devices were known as early as the aeolipile in the first ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Railway Lines Closed In 1964
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 Track (rail transport), 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 Railroad tie, sleepers (ties) set in track ballast, 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 friction, frictional resistance than rubber-tyred road vehicles, so passenger and freight cars (carriages and wagons) can be coupled into longer trains. The rail transport operations, operation is carried out by a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

10 Ft Gauge Railways In The United States
1 (one, unit, unity) is a number representing a single or the only entity. 1 is also a numerical digit and represents a single unit of counting or measurement. For example, a line segment of ''unit length'' is a line segment of length 1. In conventions of sign where zero is considered neither positive nor negative, 1 is the first and smallest positive integer. It is also sometimes considered the first of the infinite sequence of natural numbers, followed by 2, although by other definitions 1 is the second natural number, following 0. The fundamental mathematical property of 1 is to be a multiplicative identity, meaning that any number multiplied by 1 equals the same number. Most if not all properties of 1 can be deduced from this. In advanced mathematics, a multiplicative identity is often denoted 1, even if it is not a number. 1 is by convention not considered a prime number; this was not universally accepted until the mid-20th century. Additionally, 1 is the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
