ALP-45DP 4504 On Head Of Train 1009, At Hoboken Terminal 6-1-12
The Bombardier ALP-45DP is a type of single cab dual-mode locomotive built by Bombardier Transportation (later Alstom) and operated by New Jersey Transit and Exo. Operators New Jersey Transit New Jersey Transit (NJT) purchased 26 ALP-45DPs in 2008, with an option to purchase up to 63 additional units. The first locomotive from the order was displayed at Innotrans in 2010 and was officially unveiled at Pennsylvania Station on May 11, 2011. NJT purchased 9 additional units in July 2010. The locomotives from these two orders are numbered 4500–4534. The ALP-45DPs are used on the Morristown Line, Montclair-Boonton Line, Raritan Valley Line, Northeast Corridor Line, and the North Jersey Coast Line, providing a one-seat ride into New York Penn Station. They are also used on the Main Line, Bergen County Line, Pascack Valley Line, and occasionally on Metro-North Railroad's Port Jervis Line. They have replaced all GP40FH-2 locomotives (except those owned by Metro-North), and a maj ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electro-diesel Locomotive
An electro-diesel locomotive (also referred to as a dual-mode or bi-mode locomotive) is a type of locomotive that can be powered either from an electricity supply (like an electric locomotive) or by using the onboard diesel engine (like a diesel-electric locomotive). For the most part, these locomotives are built to serve regional, niche markets with a very specific purpose. Overview Electro-diesel locomotives are used to provide continuous journeys along routes that are only partly electrified without a change of locomotive, avoid extensive running of ''diesel under the wires'' (using a diesel locomotive where electrified lines are available), and giving solution where diesel engines are banned. They may be designed or adapted mainly for electric use, mainly for diesel use or to work well as either electric or diesel. Note that, as well as the electric multiple unit (EMU) and diesel multiple unit (DMU), where no discrete locomotive is present, an electro-diesel (bi-mode) ...

Railway Disc Brake
A disc brake is a type of brake that uses the calipers to squeeze pairs of pads against a disc or a "rotor" to create friction. This action slows the rotation of a shaft, such as a vehicle axle, either to reduce its rotational speed or to hold it stationary. The energy of motion is converted into waste heat which must be dispersed. Hydraulically actuated disc brakes are the most commonly used form of brake for motor vehicles, but the principles of a disc brake are applicable to almost any rotating shaft. The components include the disc, master cylinder, and caliper (which contains a cylinder and two brake pads) on both sides of the disc. Design The development of disc-type brakes began in England in the 1890s. In 1902, the Lanchester Motor Company designed brakes that looked and operated in a similar way to a modern disc-brake system even though the disc was thin and a cable activated the brake pad. Other designs were not practical or widely available in cars for another 6 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Railway Brake
A railway brake is a type of brake used on the cars of railway trains to enable deceleration, control acceleration (downhill) or to keep them immobile when parked. While the basic principle is similar to that on road vehicle usage, operational features are more complex because of the need to control multiple linked carriages and to be effective on vehicles left without a prime mover. Clasp brakes are one type of brakes historically used on trains. Early days In the earliest days of railways, braking technology was primitive. The first trains had brakes operative on the locomotive tender and on vehicles in the train, where "porters" or, in the United States brakemen, travelling for the purpose on those vehicles operated the brakes. Some railways fitted a special deep-noted brake whistle to locomotives to indicate to the porters the necessity to apply the brakes. All the brakes at this stage of development were applied by operation of a screw and linkage to brake blocks applied ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Westinghouse Air Brake Company
The Westinghouse Air Brake Company (sometimes nicknamed or abbreviated WABCO although this was also confusingly used for spinoffs) was founded on September 28, 1869 by George Westinghouse in Pittsburgh, Pennsylvania. Earlier in the year he had invented the railway air brake in New York state. After having manufactured equipment in Pittsburgh for a number of years, he began to construct facilities and plants east of the city where homes for his employees were built. In 1889, the air brake manufacturing facility was moved to Wilmerding, Pennsylvania, and the company's general office building was built there in 1890. In 1921 the company began manufacturing a modified air brake system for installation in trucks and heavy vehicles. In 1953 WABCO entered the heavy equipment marketplace, buying the assets of leading equipment designer R.G LeTourneau. An entity known as LeTourneau-Westinghouse sold a range of innovative products, including scrapers, cranes and bulldozers until 196 ...

Dynamic Braking
Dynamic braking is the use of an electric traction motor as a generator when slowing a vehicle such as an electric or diesel-electric locomotive. It is termed " rheostatic" if the generated electrical power is dissipated as heat in brake grid resistors, and " regenerative" if the power is returned to the supply line. Dynamic braking reduces wear on friction-based braking components, and regeneration lowers net energy consumption. Dynamic braking may also be used on railcars with multiple units, light rail vehicles, electric trams, trolleybuses, and electric and hybrid electric automobiles. Principle of operation Converting electrical energy to the mechanical energy of a rotating shaft (electric motor) is the inverse of converting the mechanical energy of a rotating shaft to electrical energy (electric generator). Both are accomplished through the interactions of armature windings with a (relatively) moving external magnetic field, with the armature connected to an electrical ...

Regenerative Braking
Regenerative braking is an energy recovery mechanism that slows down a moving vehicle or object by converting its kinetic energy into a form that can be either used immediately or stored until needed. In this mechanism, the electric traction motor uses the vehicle's momentum to recover energy that would otherwise be lost to the brake discs as heat. This method contrasts with conventional braking systems. In those systems, the excess kinetic energy is converted to unwanted and wasted heat due to friction in the brakes, or with rheostatic brakes, where the energy is recovered by using electric motors as generators but is immediately dissipated as heat in resistors. In addition to improving the overall efficiency of the vehicle, regeneration can significantly extend the life of the braking system as the mechanical parts will not wear out quickly. General principle The most common form of regenerative brake involves an electric motor functioning as an electric generator. In elect ...

Head End Power
In rail transport, head-end power (HEP), also known as electric train supply (ETS), is the electrical power distribution system on a passenger train. The power source, usually a locomotive (or a generator car) at the front or 'head' of a train, provides the electricity used for heating, lighting, electrical and other 'hotel' needs. The maritime equivalent is hotel electric power. A successful attempt by the London, Brighton and South Coast Railway in October 1881 to light the passenger cars on the London to Brighton route heralded the beginning of using electricity to light trains in the world. History Oil lamps were introduced in 1842 to light trains. Economics drove the Lancashire and Yorkshire Railway to replace oil with coal gas lighting in 1870, but a gas cylinder explosion on the train led them to abandon the experiment. Oil-gas lighting was introduced in late 1870. Electrical lighting was introduced in October 1881 by using twelve Swan carbon filament incandescent lamps c ...

EMD GP40-based Passenger Locomotives
The passenger locomotives derivatives of the General Motors EMD GP40 diesel-electric locomotive have been, and continue to be, used by multiple passenger railroads in North America. For passenger service, the locomotives required extra components for providing steam or head-end power (HEP) for heating, lighting and electricity in passenger cars. Most of these passenger locomotives were rebuilt from older freight locomotives, while some were built as brand new models. GP40TC The GMD GP40TC was built by General Motors Diesel (GMD), for GO Transit in Toronto. Eight units were manufactured between 1966 and 1968. They were built on an enlarged frame to accommodate a head-end power generator. GO Transit sold the fleet to Amtrak in 1988, where they were based in Chicago and used on short-haul trains. In 2005, the Norfolk Southern Railway rebuilt all eight GP40TC locomotives at its Juniata Shops in Altoona, Pennsylvania. These are now classed as GP38H-3, and work as maintenance-of- ...

PL42AC
The Alstom PL42AC is a class of four axle B-B diesel-electric locomotive designed by Alstom in association with GM-EMD. 33 were built between 2003 and 2006 for NJ Transit Rail Operations. Description The PL42AC is a diesel-electric 4-axle locomotive built by Alstom with 16-710G3B prime mover for New Jersey Transit. The first two locomotives were manufactured at the Meinfesa plant in Valencia, Spain in 2003. The 31 following units were assembled at the Alstom Transport plant in Hornell, New York in 2004, and were produced through early 2006. The power rating of the PL42AC locomotives is 4,200 hp (3.1 MW) total for tractive effort and head-end power. The locomotive has a design similar to the GE Genesis, mainly due to the fact that both PL42AC and Genesis series locomotives were designed by industrial designer Cesar Vergara. This locomotive uses IGBT technology with precise traction computers for tractive effort. The PL42AC has 800 kilowatts head-end power and WAB ...

ALP-44
The ABB ALP-44 was an electric locomotive which was built by Asea Brown Boveri of Sweden between 1989 and 1997 for the New Jersey Transit and SEPTA railway lines. Service New Jersey Transit New Jersey Transit acquired 32 ALP-44s for use on its electric railway lines. The first fifteen, numbered 4400–4414 and designated ALP-44O (Original), were delivered in 1990 (prototypes 4400 and 4401 in late 1989). Five additional units, numbered 4415–4419 and designated ALP-44E (Extended), were delivered in 1995. The final 12 locomotives, numbered 4420–4431 and designated ALP-44M (Microprocessor), were delivered in 1996 for the new Midtown Direct service. NJT's ALP-44s were to be overhauled for a cost of $2 million during a two-year period by Philadelphia-based Interfleet Technology. A car builder had not yet been selected to carry out the overhaul. However, by June 2009, NJT decided that it would be more efficient (economically and physically) to replace the ALP-44s rather than overh ...
