Sydney Trains T Set
The T sets, also referred to as the Tangara trains, are a class of electric multiple units that currently operate on the Sydney Trains network. Built by A Goninan & Co, the sets entered service between 1988 and 1995, initially under the State Rail Authority and later CityRail. The T sets were built as "third-generation" trains for Sydney's rail fleet, coinciding with the final withdrawals of the "Red Rattler" sets from service in the late 1980s and early 1990s. The Tangaras were initially built as two classes; the long-distance G sets and the suburban T sets, before being merged after successive refurbishments. Design The Tangara is a double-deck four-car set, with the two outer cars being driving control trailers (carrying a D prefix) that are fitted with one pantograph each and the middle two cars being non-control motor cars (carrying an N prefix). All sets are equipped with chopper control. Unlike most other Sydney Trains rolling stock, the seats on the suburban T sets ...

Chopper (electronics)
In electronics, a chopper circuit is any of numerous types of electronic switching devices and circuits used in power control and signal applications. A chopper is a device that converts fixed DC input to a variable DC output voltage directly. Essentially, a chopper is an electronic switch that is used to interrupt one signal under the control of another. In power electronics applications, since the switching element is either fully on or fully off, its losses are low and the circuit can provide high efficiency. However, the current supplied to the load is discontinuous and may require smoothing or a high switching frequency to avoid undesirable effects. In signal processing circuits, use of a chopper stabilizes a system against drift of electronic components; the original signal can be recovered after amplification or other processing by a synchronous demodulator that essentially un-does the "chopping" process. Comparison (step down chopper and step up chopper) Comparison bet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pulse-width Modulation
Pulse-width modulation (PWM), or pulse-duration modulation (PDM), is a method of reducing the average power delivered by an electrical signal, by effectively chopping it up into discrete parts. The average value of voltage (and current) fed to the load is controlled by turning the switch between supply and load on and off at a fast rate. The longer the switch is on compared to the off periods, the higher the total power supplied to the load. Along with maximum power point tracking (MPPT), it is one of the primary methods of reducing the output of solar panels to that which can be utilized by a battery. PWM is particularly suited for running inertial loads such as motors, which are not as easily affected by this discrete switching, because their inertia causes them to react slowly. The PWM switching frequency has to be high enough not to affect the load, which is to say that the resultant waveform perceived by the load must be as smooth as possible. The rate (or frequency) a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bilevel Rail Car
A bilevel car (American English) or double-decker coach (British English and Canadian English) is a type of rail car that has two levels of passenger accommodation, as opposed to one, increasing passenger capacity (in example cases of up to 57% per car). The use of double-decker carriages, where feasible, can resolve capacity problems on a railway, avoiding other options which have an associated infrastructure cost such as longer trains (which require longer station platforms), more trains per hour (which the signalling or safety requirements may not allow) or adding extra tracks besides the existing line. Double deck trains are claimed to be more energy efficient, and may have a lower operating cost per passenger. A double deck car may carry up to about twice as many as a normal car, if structure and loading gauges permit, without requiring double the weight to pull or material to build. However, a double deck train may take longer to exchange passengers at each station, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

New South Wales Standard Suburban Carriage Stock
The New South Wales Standard suburban carriage stock are a class of electric multiple units that were operated by the New South Wales Government Railways and its successors between 1926 and 1992. They served on the Sydney suburban network. In the years before their withdrawal, they were nicknamed ''Red Rattlers''.This term was imported from Victoria and was never a contemporaneous colloquialism. History To provide rolling stock for the electrification of Sydney's suburban rail network, steel carriages were ordered."Sydney's Electric Trains from 1926 to 1960" '' ARHS Bulletin'' issue 761 March 2001 pages 90-93 The initial 50 power cars were built in England by Leeds Forge Company and shipped to Australia in knocked-down condition. They were assembled by Eveleigh Carriage Workshops (10) and Clyde Engineering (40) between April and October 1925. Initially numbered 2213-2262, they entered service being inserted into sets with Bradfield carriages for haulage by steam locomotives un ...

CityRail
CityRail was a passenger railway brand operated by the State Rail Authority from 1989 to 2003 and by RailCorp from 2003 to 2013 with services in and around Sydney, Newcastle and Wollongong, the three largest cities in New South Wales, Australia. It was established in January 1989 and abolished in June 2013 when it was superseded by Sydney Trains and NSW TrainLink. In June 2013, it operated 307 stations and over 2,060 kilometres of track, extending north to the upper Hunter Region, south to the Shoalhaven and Southern Highlands regions and west to Bathurst. In the year ended 30 June 2012, 306 million journeys were made on the network. History Structure CityRail was established pursuant to the , and was first mentioned as an entity distinct from the State Rail Authority in the Parliament of New South Wales by then governor James Rowland on 21 February 1990. CityRail adopted a blue and yellow version of the State Rail Authority ''L7'' logo, to fit into its new blue and yellow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
State Rail Authority
The State Rail Authority, a former statutory authority of the Government of New South Wales, operated and maintained railways in the Australian state of New South Wales from July 1980 until December 2003. History The ''Transport Authorities Act 1980'' separated the functions of the Public Transport Commission (formerly responsible for all public transport) and established the State Rail Authority. The State Rail Authority assumed responsibility for trains, while the Urban Transit Authority responsibility for buses and ferries. In July 1982 a new colour scheme developed by Phil Belbin of red, yellow, orange and white was unveiled, which was commonly referred to as the "candy colours". The ''L7'' logo used by the Public Transport Commission was retained, albeit with the dark and light blue replaced with red and orange. Around this time, they also gave playing cards and soap to passengers. Electrification During its tenure the State Rail Authority completed a number of electr ...

Electric Multiple Unit
An electric multiple unit or EMU is a multiple-unit train consisting of self-propelled carriages using electricity as the motive power. An EMU requires no separate locomotive, as electric traction motors are incorporated within one or a number of the carriages. An EMU is usually formed of two or more semi-permanently coupled carriages, but electrically powered single-unit railcars are also generally classed as EMUs. The great majority of EMUs are passenger trains, but versions also exist for carrying mail. EMUs are popular on commuter and suburban rail networks around the world due to their fast acceleration and pollution-free operation. Being quieter than diesel multiple units (DMUs) and locomotive-hauled trains, EMUs can operate later at night and more frequently without disturbing nearby residents. In addition, tunnel design for EMU trains is simpler as no provision is needed for exhausting fumes, although retrofitting existing limited-clearance tunnels to accommodate the ...

Scharfenberg Coupler
The Scharfenberg coupler (german: Scharfenbergkupplung, abbreviated ''Schaku'') is a commonly used type of fully automatic railway coupling. Designed in 1903 by Karl Scharfenberg in Königsberg, Germany (today Kaliningrad, Russia), the coupler has gradually spread from transit trains to regular passenger service trains, although outside Europe its use is generally restricted to mass transit systems. The ''Schaku'' is superior in many ways to the AAR (Janney/knuckle) coupler because it also automates electrical and pneumatic connections and disconnections. However, there is no standard for the placement of these electro-pneumatic connections. Some rail operators have placed them on the sides while others have placed them either below or above the mechanical portion of the coupler. . Working principles The face of the Scharfenberg coupler has a protruding cone and a matching cup. Inside the cone there is a rigid metal hoop connected to a revolving, spring-loaded metal disk with a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nippon Sharyo
, formed in 1896, is a major rolling stock manufacturer based in Nagoya, Japan. In 1996, it abbreviated its name to "日本車両" Nippon Sharyō. Its shortest abbreviation is Nissha "日車". It was a listed company on Nikkei 225 until 2004. It is listed on the Tokyo Stock Exchange and Nagoya Stock Exchange as ticker 7102. In 2008, Central Japan Railway Company (JR Central) became the majority shareholder (50.1%) of the financially struggling Nippon Sharyo making the firm a "consolidated subsidiary" of JR Central. In July 2012 Nippon Sharyo USA started production in their new facility in Rochelle, Illinois. The facility closed at the end of October 2018 due to a lack of orders.

Pantograph (transport)
A pantograph (or "pan" or "panto") is an apparatus mounted on the roof of an electric train, tram or electric bus to collect power through contact with an overhead line. By contrast, battery electric buses and trains are charged at charging stations. The pantograph is a common type of current collector; typically, a single or double wire is used, with the return current running through the rails. The term stems from the resemblance of some styles to the mechanical pantographs used for copying handwriting and drawings. Invention The pantograph, with a low-friction, replaceable graphite contact strip or "shoe" to minimise lateral stress on the contact wire, first appeared in the late 19th century. Early versions include the bow collector, invented in 1889 by Walter Reichel, chief engineer at Siemens & Halske in Germany, and a flat slide-pantograph first used in 1895 by the Baltimore and Ohio Railroad The familiar diamond-shaped roller pantograph was devised and patented b ...
