M9 (railcar)
The M9 is a class of electric multiple unit railroad cars being built by Kawasaki Heavy Industries for use on the MTA's Long Island Rail Road (LIRR) and Metro-North Railroad. They entered service September 11, 2019. These cars will replace the M3/M3A railcars built during the early 1980s, as well as expand the LIRR fleet to provide additional service after the completion of the LIRR's East Side Access project. A separate order of cars purchased for the LIRR and Metro-North using federal funding for the East Side Access project will also be designated M9A. History Contract timeline In mid-2012, the MTA issued a joint procurement request for the LIRR and Metro-North for a total of up to 676 M9 railcars, set for delivery between 2016 and 2020. On September 18, 2013, Kawasaki Heavy Industries was awarded a nearly $1.8 billion contract for the order, comprising a base order of 92 cars for the LIRR (costing $355 million) with options for an additional 584 cars (304 for the LIRR and 28 ...

Woodside Station (LIRR)
Woodside is a station on the Long Island Rail Road's Main Line and Port Washington Branch in the Woodside neighborhood of Queens, New York City. It is the first station passed by eastward trains from Penn Station, and it is the only station in Queens shared by the Port Washington Branch and other LIRR branches. East of Woodside the two-track Port Washington Branch turns eastward, while the four-track Main Line continues southeast to Jamaica station. Woodside has six tracks and three platforms. The four southernmost tracks passing through the station are the Main Line tracks; the two center tracks on the Main Line are through (express) tracks and do not have platform faces at Woodside. The two northernmost tracks are the Port Washington branch tracks, both of which have platforms. West of the station, the line merges with Amtrak's Hell Gate Bridge access tracks (part of the Northeast Corridor) at Harold Interlocking before entering the East River Tunnels to Manhattan. The 61st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
East Side Access
East Side Access (ESA) is a public works project in New York City that extended the Long Island Rail Road (LIRR) from its Main Line in Queens into a new station under Grand Central Terminal on Manhattan's East Side. A project of the Metropolitan Transportation Authority (MTA) originally scheduled to open in 2009, the new station and tunnels are tentatively scheduled to start service in December 2022. For several weeks there will be a shuttle service schedule, then full service.The project's estimated construction cost rose nearly threefold from the planned $3.5 billion to $11.1 billion , making it one of the world's most expensive underground rail-construction projects. East Side Access is based on transit plans from the 1950s, though an LIRR terminal on Manhattan's East Side was first proposed in 1963. The planned LIRR line was included in the 1968 Program for Action of transit improvements in the New York City area. Lack of funds prevented the construction of any ...

Light-emitting Diode
A light-emitting diode (LED) is a semiconductor device that emits light when current flows through it. Electrons in the semiconductor recombine with electron holes, releasing energy in the form of photons. The color of the light (corresponding to the energy of the photons) is determined by the energy required for electrons to cross the band gap of the semiconductor. White light is obtained by using multiple semiconductors or a layer of light-emitting phosphor on the semiconductor device. Appearing as practical electronic components in 1962, the earliest LEDs emitted low-intensity infrared (IR) light. Infrared LEDs are used in remote-control circuits, such as those used with a wide variety of consumer electronics. The first visible-light LEDs were of low intensity and limited to red. Early LEDs were often used as indicator lamps, replacing small incandescent bulbs, and in seven-segment displays. Later developments produced LEDs available in visible, ultraviolet (UV) ...

Public Address System
A public address system (or PA system) is an electronic system comprising microphones, amplifiers, loudspeakers, and related equipment. It increases the apparent volume (loudness) of a human voice, musical instrument, or other acoustic sound source or recorded sound or music. PA systems are used in any public venue that requires that an announcer, performer, etc. be sufficiently audible at a distance or over a large area. Typical applications include sports stadiums, public transportation vehicles and facilities, and live or recorded music venues and events. A PA system may include multiple microphones or other sound sources, a mixing console to combine and modify multiple sources, and multiple amplifiers and loudspeakers for louder volume or wider distribution. Simple PA systems are often used in small venues such as school auditoriums, churches, and small bars. PA systems with many speakers are widely used to make announcements in public, institutional and commercial buildings ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
M8 (railcar)
The M8 is an electric multiple unit railroad car built by Kawasaki for use on the Metro-North Railroad New Haven Line and the CTrail Shore Line East. The fleet of 471 cars first entered service in 2011, replacing the M2, M4 and M6 cars, which entered service in 1973, 1987 and 1994, respectively. An additional 60-car order is currently finishing delivery in response to increased ridership and usage on Shore Line East. Design The M8 is similar in design to the M7 car used on the Harlem Line and the Hudson Line. Like the M7, the M8 is able to pick up 750 V DC power from bottom-contact third rail for operation along the New Haven Line from Grand Central Terminal to Pelham, where the traction power source is transferred to the overhead catenary wire. The overhead wire is at a nominal 12.5 kV AC (60 Hz) power from overhead lines via pantographs for operation from Pelham, New York to New Haven, Connecticut (as well as along the New Canaan Branch), and 25 kV AC (60 Hz) power from ...

M7 (railcar)
The M7 is an electric multiple unit railroad car built by Bombardier, with delivery beginning in 2002, used by the MTA on the Long Island Rail Road (M7) and Metro-North Railroad (M7A). The M7 replaced the M1 railcars, which had previously provided electric service on these lines. The M7 fleets are powered from an electric third rail. A total of 1,172 M7 cars were built for the two railroads. Description Cars are arranged as married pairs, where each car contains a complete set of controls for an engineer, conductor, or brakeman. However, the 'B' Cars (denoted by odd-numbered car designations) contain a handicapped accessible restroom, which is larger than the restroom provided on the M1 and M3 railcars and designed to accommodate a wheelchair, as well as an attendant and/or service animal (such as a guide dog, hearing dog or service dog) accompanying the passenger. The enlarged bathroom reduces the number of seats in the car. The M7 was built as two separate but similar m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CCTV Camera
A closed-circuit television camera can produce images or recordings for surveillance or other private purposes. Cameras can be either video cameras, or digital stills cameras. Walter Bruch was the inventor of the CCTV camera. The main purpose of a CCTV camera is to capture light and convert it into a video signal. Underpinning a CCTV camera is a CCD sensor (charge-coupled device). The CCD converts light into an electrical signal and then signal processing converts this electrical signal into a video signal that can be recorded or displayed on the screen. Video cameras Video cameras are either analogue or digital, which means that they work on the basis of sending analogue or digital signals to a storage device such as a video tape recorder or desktop computer or laptop computer. Analogue These cameras can record straight to a video tape recorder which can record analogue signals as pictures. If the analogue signals are recorded to tape, then the tape must run at a very ...

Positive Train Control
Positive train control (PTC) is a family of automatic train protection systems deployed in the United States. Most of the United States' national rail network mileage has a form of PTC. These systems are generally designed to check that trains are moving safely and to stop them when they are not. A simplistic form of train traffic governance is ''negative'' train control, where trains must stop when issued a stop order and can move in the absence of such. An example of negative train control is Indusi. In contrast, ''positive'' train control restricts the train movement to an explicit allowance; movement is halted upon invalidation. A train operating under PTC receives a ''movement authority'' containing information about its location and where it is allowed to safely travel. As of 2019, the U.S. freight rail industry trade organization AAR claimed that the nation's largest freight railroads were operating PTC across 83.2 percent of the required route miles. The American Railwa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

COVID-19 Pandemic
The COVID-19 pandemic, also known as the coronavirus pandemic, is an ongoing global pandemic of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The novel virus was first identified in an outbreak in the Chinese city of Wuhan in December 2019. Attempts to contain it there failed, allowing the virus to spread to other areas of Asia and later worldwide. The World Health Organization (WHO) declared the outbreak a public health emergency of international concern on 30 January 2020, and a pandemic on 11 March 2020. As of , the pandemic had caused more than cases and confirmed deaths, making it one of the deadliest in history. COVID-19 symptoms range from undetectable to deadly, but most commonly include fever, dry cough, and fatigue. Severe illness is more likely in elderly patients and those with certain underlying medical conditions. COVID-19 transmits when people breathe in air contaminated by droplets and ...

Port Jefferson Branch
The Port Jefferson Branch is a rail line and service owned and operated by the Long Island Rail Road in the U.S. state of New York. The branch splits from the Main Line just east of Hicksville and runs northeast and east to Port Jefferson. Several stations on the Main Line west of Hicksville are served primarily by trains bound to/from the Port Jefferson branch, so LIRR maps and schedules for the public include that part of the Main Line in the "Port Jefferson Branch" service. The Port Jefferson Branch is one of the busiest branches of the LIRR, with frequent electric service to Huntington where electrification ends, and diesel service east of Huntington continuing to Port Jefferson. The MTA also refers to the line as the "Huntington/Port Jefferson Branch" or "Huntington Branch". Service Port Jefferson Branch service (as distinct from the physical trackage called the Port Jefferson Branch) extends east from Floral Park, where the Hempstead Branch separates from the Main Line.
