Huntingdon Station (SEPTA)
Huntingdon station is a SEPTA elevated rapid transit station in Philadelphia, Pennsylvania, serving the Market–Frankford Line. It is located at the intersection of Kensington Avenue, Huntingdon Street, and B Street in the Kensington neighborhood of the city. It is the westernmost station on the line located above Kensington Avenue and is also served by SEPTA bus routes 3, 39, and 54. History Huntingdon is part of the Frankford Elevated section of the line, which began service on November 5, 1922. Between 1988 and 2003, SEPTA undertook a $493.3 million reconstruction of the Frankford Elevated. Huntingdon station was completely rebuilt on the site of the original station; the project included new platforms, elevators, windscreens, and overpasses, and the station now meets ADA accessibility requirements. The line had originally been built with track ballast and was replaced with precast sections of deck, allowing the station and the entire line to remain open throughout ...

Philadelphia
Philadelphia, often called Philly, is the largest city in the Commonwealth of Pennsylvania, the sixth-largest city in the U.S., the second-largest city in both the Northeast megalopolis and Mid-Atlantic regions after New York City. Since 1854, the city has been coextensive with Philadelphia County, the most populous county in Pennsylvania and the urban core of the Delaware Valley, the nation's seventh-largest and one of world's largest metropolitan regions, with 6.245 million residents . The city's population at the 2020 census was 1,603,797, and over 56 million people live within of Philadelphia. Philadelphia was founded in 1682 by William Penn, an English Quaker. The city served as capital of the Pennsylvania Colony during the British colonial era and went on to play a historic and vital role as the central meeting place for the nation's founding fathers whose plans and actions in Philadelphia ultimately inspired the American Revolution and the nation's inde ...

Railway Stations In Philadelphia
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 ...

Conrail Shared Assets
Conrail Shared Assets Operations (CSAO) is the commonly used name for modern-day Conrail (reporting mark CRCX), an American railroad company. It operates three networks, the North Jersey, South Jersey/Philadelphia, and Detroit Shared Assets Areas, where it serves as a contract local carrier and switching company for its owners, CSX Transportation and the Norfolk Southern Railway. When most of the former Conrail's track was split between these two railroads, the three shared assets areas (a total of about 1,200 miles of track) were kept separate to avoid giving one railroad an advantage in those areas. The company operates using its own employees and infrastructure but owns no equipment outside Maintenance of way, MOW equipment. North Jersey Shared Assets Area The North Jersey Shared Assets Area stretches from the North Bergen Yard in North Bergen, New Jersey south into Jersey City, New Jersey, Jersey City and Newark, New Jersey, Newark, and beyond to Manville, New Jersey, Manville ...

Truss Bridge
A truss bridge is a bridge whose load-bearing superstructure is composed of a truss, a structure of connected elements, usually forming triangular units. The connected elements (typically straight) may be stressed from tension, compression, or sometimes both in response to dynamic loads. The basic types of truss bridges shown in this article have simple designs which could be easily analyzed by 19th and early 20th-century engineers. A truss bridge is economical to construct because it uses materials efficiently. Design The nature of a truss allows the analysis of its structure using a few assumptions and the application of Newton's laws of motion according to the branch of physics known as statics. For purposes of analysis, trusses are assumed to be pin jointed where the straight components meet, meaning that taken alone, every joint on the structure is functionally considered to be a flexible joint as opposed to a rigid joint with strength to maintain its own shape, and th ...

Skip-stop
Skip-stop is a public transit service pattern which reduces travel times and increases capacity by having vehicles ''skip'' certain ''stops'' along a route. Originating in rapid transit systems, skip-stop may be also used in light rail and bus systems. "Skip-stop" is also used to describe elevators that stop at alternating floors and hence also used to describe building designs that exploit this design and avoid corridors on alternating floors. Rationale Skip-stop service is one solution to increasing train speed at minimal cost. In rapid transit systems in the United States, stations tend to be close together (approximately in 1976), and so trains struggle to reach high speeds. The New York City Subway for example, the slowest in the United States, travels at an average speed of . Trains on the same track cannot pass each other like buses can, and so to increase speed, changes can only be made in terms of headway, or in which stations are served. Skipping stations increas ...

National Academies Of Sciences, Engineering, And Medicine
The National Academies of Sciences, Engineering, and Medicine (also known as NASEM or the National Academies) are the collective scientific national academy of the United States. The name is used interchangeably in two senses: (1) as an umbrella term for its three quasi-independent honorific member organizations the National Academy of Sciences (NAS), the National Academy of Engineering (NAE), and the National Academy of Medicine (NAM); and (2) as the brand for studies and reports issued by the operating arm of the three academies, the National Research Council (NRC). The NRC was first formed in 1916 as an activity of the NAS. Now jointly governed by all three academies, the NRC produces some 200 publications annually which are published by the National Academies Press. The reports produced by the National Academies have been characterized as reflective of scientific consensus. History The US National Academy of Sciences was created by an Act of Incorporation dated March 3, 18 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Track Ballast
Track ballast forms the trackbed upon which railroad ties (sleepers) are laid. It is packed between, below, and around the ties. It is used to bear the load from the railroad ties, to facilitate drainage of water, and also to keep down vegetation that might interfere with the track structure. Ballast also holds the track in place as the trains roll over it. A variety of materials have been used as track ballast, including crushed stone, washed gravel, bank run (unwashed) gravel, torpedo gravel (a mixture of coarse sand and small gravel), slag, chats, coal cinders, sand, and burnt clay. The term "ballast" comes from a nautical term for the stones used to stabilize a ship. Construction The appropriate thickness of a layer of track ballast depends on the size and spacing of the ties, the amount of traffic on the line, and various other factors. Track ballast should never be laid down less than thick, and high-speed railway lines may require ballast up to thick.Bell 2004, p. 39 ...

Americans With Disabilities Act Of 1990
The Americans with Disabilities Act of 1990 or ADA () is a civil rights law that prohibits discrimination based on disability. It affords similar protections against discrimination to Americans with disabilities as the Civil Rights Act of 1964, which made discrimination based on race, religion, sex, national origin, and other characteristics illegal, and later sexual orientation and gender identity. In addition, unlike the Civil Rights Act, the ADA also requires covered employers to provide reasonable accommodations to employees with disabilities, and imposes accessibility requirements on public accommodations. In 1986, the National Council on Disability had recommended the enactment of an Americans with Disabilities Act (ADA) and drafted the first version of the bill which was introduced in the House and Senate in 1988. A broad bipartisan coalition of legislators supported the ADA, while the bill was opposed by business interests (who argued the bill imposed costs on busine ...
