Technology Of The New York City Subway
Since the late 20th century, the Metropolitan Transportation Authority has started several projects to maintain and improve the New York City Subway. Some of these projects, such as subway line automation, proposed platform screen doors, the FASTRACK maintenance program, and infrastructural improvements proposed in 2015–2019 Capital Program, contribute toward improving the system's efficiency. Others, such as train-arrival "countdown clocks", "Help Point" station intercoms, "On the Go! Travel Station" passenger kiosks, wireless and cellular network connections in stations, MetroCard fare payment alternatives, and digital ads, are meant to benefit individual passengers. Yet others, including the various methods of subway construction, do not directly impact the passenger interface, but are used to make subway operations efficient. In the mid-1990s, it started converting the BMT Canarsie Line to use communications-based train control, using a moving block signal system th ...

New York City Steam System
The New York City steam system includes Con Edison's Steam Operations, a piped steam system which provides steam to large parts of Manhattan. Other smaller systems provide steam to New York University and Columbia University, and many individual buildings in New York City also have their own steam systems. The steam is used to heat and cool buildings and for cleaning and disinfecting. It is the largest such system in the world and has been in operation since 1882. Con Edison's Steam Operations Con Edison's Steam Operations is a district heating system which carries steam from generating stations under the streets to heat and cool buildings and businesses in Manhattan.

Interborough Rapid Transit Company
The Interborough Rapid Transit Company (IRT) was the private operator of New York City's original underground subway line that opened in 1904, as well as earlier elevated railways and additional rapid transit lines in New York City. The IRT was purchased by the city on June 12, 1940, along with the younger BMT and IND systems, to form the modern New York City Subway. The former IRT lines (the numbered routes in the current subway system) are now the A Division or IRT Division of the Subway. History The first IRT subway ran between City Hall and 145th Street at Broadway, opening on October 27, 1904. It opened following more than twenty years of public debate on the merits of subways versus the existing elevated rail system and on various proposed routes. Founded on May 6, 1902, by August Belmont, Jr., the IRT's mission was to operate New York City's initial underground rapid transit system after Belmont's and John B.

Cut-and-cover
A tunnel is an underground or undersea passageway. It is dug through surrounding soil, earth or rock, or laid under water, and is usually completely enclosed except for the two Portal (architecture), portals common at each end, though there may be access and ventilation openings at various points along the length. A Pipeline transport, pipeline differs significantly from a tunnel, though some recent tunnels have used immersed tube construction techniques rather than traditional tunnel boring methods. A tunnel may be for foot or vehicular road traffic, for rail transport, rail traffic, or for a canal. The central portions of a rapid transit network are usually in the tunnel. Some tunnels are used as sanitary sewer, sewers or aqueduct (watercourse), aqueducts to supply water for consumption or for hydroelectric stations. Utility tunnels are used for routing steam, chilled water, electrical power or telecommunication cables, as well as connecting buildings for convenient passa ...

Four Track Subway IRT
4 (four) is a number, numeral and digit. It is the natural number following 3 and preceding 5. It is a square number, the smallest semiprime and composite number, and is considered unlucky in many East Asian cultures. Evolution of the Hindu-Arabic digit Brahmic numerals represented 1, 2, and 3 with as many lines. 4 was simplified by joining its four lines into a cross that looks like the modern plus sign. The Shunga would add a horizontal line on top of the digit, and the Kshatrapa and Pallava evolved the digit to a point where the speed of writing was a secondary concern. The Arabs' 4 still had the early concept of the cross, but for the sake of efficiency, was made in one stroke by connecting the "western" end to the "northern" end; the "eastern" end was finished off with a curve. The Europeans dropped the finishing curve and gradually made the digit less cursive, ending up with a digit very close to the original Brahmin cross. While the shape of the character fo ...

Contactless Payment
Contactless payment systems are credit cards and debit cards, key fobs, smart cards, or other devices, including smartphones and other mobile devices, that use radio-frequency identification (RFID) or near-field communication (NFC) for making secure payments. The embedded integrated circuit chip and antenna enable consumers to wave their card, fob, or handheld device over a Credit card terminal, reader at the point-of-sale terminal. Contactless payments are made in close physical proximity, unlike other types of mobile payments which use broad-area cellular or Wi-Fi networks and do not involve close physical proximity. EMV (abbreviation for Europay International, Europay, Mastercard, and Visa Inc., Visa) is a common standard used by major credit card and smartphone companies for use in general commerce. Contactless smart cards that function as stored-value cards are becoming popular for use as transit system Public transport#Electronic fare card, farecards, such as the Oyster car ...
