Kawasaki Type K LRV
The Kawasaki Light Rail Vehicle (Kawasaki LRV), commonly referred to as the K-car, is a light rail vehicle manufactured by Kawasaki Heavy Industries and used for service on tram, trolley lines operated by SEPTA. The Series 9000 is a streetcar that has been used on the SEPTA subway–surface trolley lines since 1980. The similar Series 100, which was manufactured at the same time, was also built for the Media–Sharon Hill Line. The K-cars were Kawasaki's first railroad cars for the American market. Background Since the days of privately-owned streetcars before the establishment of the publicly-owned SEPTA, high-performance PCC streetcars built by J. G. Brill Company were used on Philadelphia's streetcars. A similar vehicle manufactured by the same company, the Brilliner, was also active. In 1975, a decade after SEPTA was established, 60 PCC cars were destroyed by a fire at the Woodland Carbarn. SEPTA soon leased streetcars from the Toronto streetcar system. However, since the ...

Toronto Streetcar System
The Toronto streetcar system is a network of eleven tram, streetcar routes in Toronto, Ontario, Canada, operated by the Toronto Transit Commission (TTC). It is the List of North American light rail systems by ridership, third busiest light-rail system in North America. The network is concentrated primarily in Downtown Toronto and in proximity to the city's Toronto waterfront, waterfront. Much of the streetcar route network dates from the second half of the 19th century. Three streetcar routes operate in their own right-of-way, one in a partial right-of-way, and six operate on street trackage shared with vehicular traffic with streetcars stopping on demand at frequent stops like buses. Since 2019, the network has used Low-floor tram, low-floor streetcars, making it fully accessible. Toronto's streetcars provide most of the downtown core's surface transit service. Four of the TTC's five most heavily used surface routes are streetcar routes. In , the system had a ridership of , or ab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SEPTA PCC II
The PCC III is a series of upgraded PCC streetcars used by the Southeastern Pennsylvania Transportation Authority, in Philadelphia, Pennsylvania, for use on the SEPTA Metro G (SEPTA Metro), G. Background In the 1980s, SEPTA was in the process of upgrading its SEPTA subway–surface trolley lines, subway–surface trolley lines, replacing its fleet of PCCs with new light rail cars. Some lines, such as Routes 6, 50, 53, and 60 were converted to buses, while Routes 15, 23, and 56 continued to use PCCs into the 1990s. In 1992, SEPTA ended streetcar service on these three lines as well. In response to public outcry over the conversion, SEPTA stated that the suspension of these lines' streetcar service was temporary, and that they would be restored in 1997. However, during this time little was done to restore the lines, and as 1997 approached, it became clear that SEPTA had no immediate plans to restore streetcar service to these lines. In September 1997, at a City Council heari ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 (classification of human beings), race, religion, gender, 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 the United States, public accommodations. In 1986, the National Council on Disability had recommended the enactment of an Americans with Disabilities Act and drafted the first version of the bill which was introduced in the United States House of Representatives, House and United States Senate, Senate in 1988.

Fiber-reinforced Plastic
Fibre-reinforced plastic (FRP; also called fibre-reinforced polymer, or in American English ''fiber'') is a composite material made of a polymer matrix reinforced with fibres. The fibres are usually glass (in fibreglass), carbon (in carbon-fibre-reinforced polymer), aramid, or basalt. Rarely, other fibres such as paper, wood, boron, or asbestos have been used. The polymer is usually an epoxy, vinyl ester, or polyester thermosetting plastic, though phenol formaldehyde resins are still in use. FRPs are commonly used in the aerospace, automotive, marine, and construction industries. They are commonly found in ballistic armour and cylinders for self-contained breathing apparatuses. History Bakelite was the first fibre-reinforced plastic. Leo Baekeland had originally set out to find a replacement for shellac (made from the excretion of lac bugs). Chemists had begun to recognize that many natural resins and fibres were polymers, and Baekeland investigated the reactions of phenol an ...

Finite Element Method
Finite element method (FEM) is a popular method for numerically solving differential equations arising in engineering and mathematical modeling. Typical problem areas of interest include the traditional fields of structural analysis, heat transfer, fluid flow, mass transport, and electromagnetic potential. Computers are usually used to perform the calculations required. With high-speed supercomputers, better solutions can be achieved and are often required to solve the largest and most complex problems. FEM is a general numerical method for solving partial differential equations in two- or three-space variables (i.e., some boundary value problems). There are also studies about using FEM to solve high-dimensional problems. To solve a problem, FEM subdivides a large system into smaller, simpler parts called finite elements. This is achieved by a particular space discretization in the space dimensions, which is implemented by the construction of a mesh of the object: the numer ...

Weathering Steel
Weathering steel, often referred to by the genericised trademark COR-TEN steel and sometimes written without the hyphen as corten steel, is a group of steel alloys that form a stable external layer of rust that eliminates the need for painting. U.S. Steel, U.S. Steel (USS) holds the Trademark, registered trademark on the name COR-TEN. The name COR-TEN refers to the two distinguishing properties of this type of steel: corrosion resistance and tensile strength. Although USS sold its discrete plate business to International Steel Group (now ArcelorMittal) in 2003, it makes COR-TEN branded material in strip mill plate and sheet forms. The original COR-TEN received the standard designation A242 (COR-TEN A) from the ASTM International standards group. Newer ASTM grades are A588 (COR-TEN B) and A606 for thin sheet. All of the alloys are in common production and use. The surface oxidation generally takes six months to develop, although surface treatments can accelerate this to as lit ...

Multiple-unit Train Control
Multiple-unit train control, sometimes abbreviated to multiple-unit or MU, is a method of simultaneously controlling all the traction equipment in a train from a single location—whether it is a multiple unit comprising a number of self-powered passenger cars or a set of locomotives—with only a control signal transmitted to each unit. This contrasts with arrangements where electric motors in different units are connected directly to the power supply switched by a single control mechanism, thus requiring the full traction power to be transmitted through the train. A set of vehicles under multiple unit control is referred to as a consist in the United States. Origins Multiple unit train control was first used in electric multiple units in the 1890s. The Liverpool Overhead Railway The Liverpool Overhead Railway opened in 1893 with two-car electric multiple units, controllers in cabs at both ends directly controlling the traction current to motors on both cars.

K Car Builders Plate
K, or k, is the eleventh letter of the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is ''kay'' (pronounced ), plural ''kays''. The letter K usually represents the voiceless velar plosive. History The letter K comes from the Greek letter Κ (kappa), which was taken from the Semitic kaph, the symbol for an open hand. This, in turn, was likely adapted by Semitic tribes who had lived in Egypt from the hieroglyph for "hand" representing /ḏ/ in the Egyptian word for hand, ⟨ ḏ-r-t⟩ (likely pronounced in Old Egyptian). The Semites evidently assigned it the sound value instead, because their word for hand started with that sound. K was brought into the Latin alphabet with the name ''ka'' /kaː/ to differentiate it from C, named ''ce'' (pronounced /keː/) and Q, named ''qu'' and pronounced /kuː/. In the earliest Latin inscriptions, the letters C, K and Q were all us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
