Reading Viaduct
The Reading Viaduct, also called The Rail Park, is a disused elevated rail line in the Callowhill district of Philadelphia that has been partly transformed into a rail trail. In 2010, the Center City District and a new community organization, Friends of the Rail Park, began to evaluate options to convert the abandoned viaduct into an elevated park. On October 31, 2016, construction began on the plan's Phase 1, which added a boardwalk, benches, landscaping, and swings along a quarter-mile (400-meter) section of the viaduct from Broad Street to Callowhill Street; it also reinforced the existing 13th street bridge. The Phase 1 section opened to the public on June 14, 2018. History The Philadelphia and Reading Terminal Railroad was incorporated on April 13, 1888, leased by the Philadelphia and Reading Railway on May 1, 1891, and soon began construction. The viaduct and terminal opened on January 29, 1893. In 1984, the Reading Terminal closed, and Philadelphia's Center City Commu ...

Elevated Park
An elevated park (sometimes known as a sky park) refers to a park located above the normal ground (street) level. This type of a park has become more popular in the early 21st century, featuring in a number of urban renewal projects. While usually associated with repurposed transportation infrastructure, some elevated parks are designed on top of buildings. Elevated parks can exist, for example, on the roof of existing buildings (see also: green roof, roof garden), or on former railways, elevated roads, or other elevated urban elements (often becoming linear parks as well). Examples of a linear elevated park include New York's High Line, Chicago's Bloomingdale Line, or Seoul's Seoullo 7017 Skypark. One of the earliest of such parks was the Promenade plantée (Coulée verte René-Dumont) in Paris, dating to 1993. It has proven popular enough to encourage other cities to consider similar projects, a process that gained further momentum after the success of the High Line, the first suc ...

Philadelphia And Columbia Railroad
Philadelphia and Columbia Railroad (P&CR) (1834) was one of the earliest commercial railroads in the United States, running from Philadelphia to Columbia, Pennsylvania, it was built by the Pennsylvania Canal Commission in lieu of a canal from Columbia to Philadelphia; in 1857 it became part of the Pennsylvania Railroad. It is currently owned and operated by Amtrak as its electrified Keystone Corridor. The Philadelphia and Columbia Railroad's western terminus was located near the former ferry site known as Wright's Ferry, in the town once of that name, but now Columbia in Lancaster County. There the P&CR met with the Pennsylvania Canal—navigations and improvements on the Susquehanna River east bank approximately south of Harrisburg, Pennsylvania. Most of its right-of-way was obtained by the actions of the Pennsylvania Canal Commission which operated the railroad under the various enabling acts of the Pennsylvania legislature known as the Main Line of Public Works in supp ...

Linear Parks
Linearity is the property of a mathematical relationship ('' function'') that can be graphically represented as a straight line. Linearity is closely related to '' proportionality''. Examples in physics include rectilinear motion, the linear relationship of voltage and current in an electrical conductor (Ohm's law), and the relationship of mass and weight. By contrast, more complicated relationships are ''nonlinear''. Generalized for functions in more than one dimension, linearity means the property of a function of being compatible with addition and scaling, also known as the superposition principle. The word linear comes from Latin ''linearis'', "pertaining to or resembling a line". In mathematics In mathematics, a linear map or linear function ''f''(''x'') is a function that satisfies the two properties: * Additivity: . * Homogeneity of degree 1: for all α. These properties are known as the superposition principle. In this definition, ''x'' is not necessarily a rea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Landmarks In Philadelphia
A landmark is a recognizable natural or artificial feature used for navigation, a feature that stands out from its near environment and is often visible from long distances. In modern use, the term can also be applied to smaller structures or features, that have become local or national symbols. Etymology In old English the word ''landmearc'' (from ''land'' + ''mearc'' (mark)) was used to describe a boundary marker, an "object set up to mark the boundaries of a kingdom, estate, etc.". Starting from approx. 1560, this understanding of landmark was replaced by a more general one. A landmark became a "conspicuous object in a landscape". A ''landmark'' literally meant a geographic feature used by explorers and others to find their way back or through an area. For example, the Table Mountain near Cape Town, South Africa is used as the landmark to help sailors to navigate around southern tip of Africa during the Age of Exploration. Artificial structures are also sometimes buil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elevated Parks
An elevated railway or elevated train (also known as an el train for short) is a rapid transit railway with the tracks above street level on a viaduct or other elevated structure (usually constructed from steel, cast iron, concrete, or bricks). The railway may be broad-gauge, standard-gauge or narrow-gauge railway, light rail, monorail, or a suspension railway. Elevated railways are normally found in urban areas where there would otherwise be multiple level crossings. Usually, the tracks of elevated railways that run on steel viaducts can be seen from street level. History The earliest elevated railway was the London and Greenwich Railway on a brick viaduct of 878 arches, built between 1836 and 1838. The first of the London and Blackwall Railway (1840) was also built on a viaduct. During the 1840s there were other plans for elevated railways in London that never came to fruition. From the late 1860s onward, elevated railways became popular in US cities. The New Y ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bridges In Philadelphia
Transportation in Philadelphia involves the various modes of transport within the city and its required infrastructure. In addition to facilitating intracity travel, Philadelphia's transportation system connects Philadelphia to towns of its metropolitan area and surrounding areas within the Northeast megalopolis. The city is crossed by the Delaware Expressway (Interstate 95 or I-95) and the Schuylkill Expressway (I-76), which are the principal thoroughfares for intercity traffic. The Vine Street Expressway ( I-676) travels between I-76 and I-95 in Center City Philadelphia, and the Roosevelt Boulevard (U.S. Route 1) carries crosstown traffic in northern Philadelphia. Philadelphia's public transit system is mainly operated by the Southeast Pennsylvania Transportation Authority (SEPTA), which maintains an extensive system utilizing buses, rapid transit, commuter rail, trolleys, and the Philadelphia trackless trolley (trolleybus) system. The main rail station of Philadelphia is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bloomingdale Trail
The Bloomingdale Trail is a elevated rail trail linear park running east–west on the northwest side of Chicago. It is the longest greenway project of a former elevated rail line in the Western Hemisphere, and the second longest in the world, after the Promenade plantee linear park in Paris. In 2015, the City of Chicago converted the former Bloomingdale railway line to an elevated greenway, which forms the backbone of the 606 trail network. The Bloomingdale Trail elevated park is in the Logan Square, Humboldt Park, and West Town neighborhoods. History The Bloomingdale Line was constructed in 1873 by the Chicago & Pacific Railroad Company as part of the Elgin subdivision from Halsted Street in Chicago to the suburb of Elgin, Illinois. It was soon absorbed by the Chicago, Milwaukee, St. Paul and Pacific Railway (also known as the Milwaukee Road), first via a 999-year lease in 1880 and later with a fee simple deed conveyance to the same in 1900. As a result of mergers an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
High Line
The High Line is a elevated linear park, greenway and rail trail created on a former New York Central Railroad spur on the west side of Manhattan in New York City. The High Line's design is a collaboration between James Corner Field Operations, Diller Scofidio + Renfro, and Piet Oudolf. The abandoned spur has been redesigned as a "living system" drawing from multiple disciplines which include landscape architecture, urban design, and ecology. The High Line was inspired by the long Promenade plantée (tree-lined walkway), a similar project in Paris completed in 1993. The park is built on a disused, southern viaduct section of the New York Central Railroad's West Side Line. Originating in the Meatpacking District, the park runs from Gansevoort Street – three blocks below 14th Street – through Chelsea to the northern edge of the West Side Yard on 34th Street near the Javits Center. The West Side Line formerly extended south to a railroad terminal at Spring ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chinese Wall (Philadelphia)
Penn Center is the heart of Philadelphia's central business district. It takes its name from the nearly five million square foot office and retail complex it contains. It lies between 15th and 19th Streets, and between John F. Kennedy Boulevard and Market Street. It is credited with bringing Philadelphia into the era of modern office buildings. History In 1881, the Pennsylvania Railroad brought passenger service into the center of the city, and constructed the first Broad Street Station just west of City Hall. The sea of iron pillars holding up the PRR's elevated trackbed was replaced in the 1890s by a 10-block stone viaduct to the Schuylkill River. This created a block-wide barrier known as ''The Chinese Wall'', cutting the western portion of the city in half and discouraging development there. At the time, most commercial activity in Center City was east of Broad Street, which is why the SEPTA Market-Frankford Line has no stops between 30th Street Station and 15th Str ...

30th Street Station
3 (three) is a number, numeral and digit. It is the natural number following 2 and preceding 4, and is the smallest odd prime number and the only prime preceding a square number. It has religious or cultural significance in many societies. Evolution of the Arabic digit The use of three lines to denote the number 3 occurred in many writing systems, including some (like Roman and Chinese numerals) that are still in use. That was also the original representation of 3 in the Brahmic (Indian) numerical notation, its earliest forms aligned vertically. However, during the Gupta Empire the sign was modified by the addition of a curve on each line. The Nāgarī script rotated the lines clockwise, so they appeared horizontally, and ended each line with a short downward stroke on the right. In cursive script, the three strokes were eventually connected to form a glyph resembling a with an additional stroke at the bottom: ३. The Indian digits spread to the Caliphate in the 9th ...
