New South Wales Bradfield Suburban Carriage Stock
The New South Wales Bradfield suburban carriage stock were a type of electric multiple unit operated by the New South Wales Government Railways and its successors between 1921 and 1975. History With the electrification of the Sydney suburban network planned, in 1919 orders were placed for 100 carriages with contracts awarded to three builders, Clyde Engineering (42), Ritchie Brothers (18) and Meadowbank Manufacturing Company (40). The carriages featured wooden bodies on steel underframes with 43 fitted out as EBB first class carriages and 57 as EBA second class. The carriages gained the Bradfield carriages nickname after the New South Wales Railway's Chief Engineer John Bradfield, even though they were designed by Chief Mechanical Engineer Edward Lucy.C3045 Bradfield Suburban Car NSW En ...

Direct Current
Direct current (DC) is one-directional flow of electric charge. An electrochemical cell is a prime example of DC power. Direct current may flow through a conductor such as a wire, but can also flow through semiconductors, insulators, or even through a vacuum as in electron or ion beams. The electric current flows in a constant direction, distinguishing it from alternating current (AC). A term formerly used for this type of current was galvanic current. The abbreviations ''AC'' and ''DC'' are often used to mean simply ''alternating'' and ''direct'', as when they modify ''current'' or ''voltage''. Direct current may be converted from an alternating current supply by use of a rectifier, which contains electronic elements (usually) or electromechanical elements (historically) that allow current to flow only in one direction. Direct current may be converted into alternating current via an inverter. Direct current has many uses, from the charging of batteries to large power sup ...

Sydney Electric Train Society
Sydney ( ) is the capital city of the state of New South Wales, and the most populous city in both Australia and Oceania. Located on Australia's east coast, the metropolis surrounds Sydney Harbour and extends about towards the Blue Mountains to the west, Hawkesbury to the north, the Royal National Park to the south and Macarthur to the south-west. Sydney is made up of 658 suburbs, spread across 33 local government areas. Residents of the city are known as "Sydneysiders". The 2021 census recorded the population of Greater Sydney as 5,231,150, meaning the city is home to approximately 66% of the state's population. Estimated resident population, 30 June 2017. Nicknames of the city include the 'Emerald City' and the 'Harbour City'. Aboriginal Australians have inhabited the Greater Sydney region for at least 30,000 years, and Aboriginal engravings and cultural sites are common throughout Greater Sydney. The traditional custodians of the land on which modern Sydney stands are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transport Heritage NSW
In 2013, Transport Heritage NSW was established by the Government of New South Wales to manage the State’s rail heritage collection and provide support to the broader transport (bus, tram, rail) heritage sector in NSW following an independent review. History In May 2013, Minister for Transport Gladys Berejiklian acknowledged the importance of steam locomotive 3801, stating it would be a priority of Transport Heritage NSW to return it to service. On 10 December 2013, a majority of the members of the New South Wales Rail Transport Museum voted in support of the creation of Transport Heritage NSW. Other transport heritage groups also expressed concern for their future existence. Peter Lowry was appointed as chairperson of the board and the nominated chief executive of Transport Heritage NSW, Andrew Killingsworth has been seen as a political appointment. In February 2016, Andrew Moritz was appointed as the new chief executive following the resignation of Andrew Killingsworth. O ...

Sydney Trains S Set
The S sets were a class of electric multiple units that operated on Sydney's suburban rail network from 1972 up until 2019. Originally entering service under the Public Transport Commission, the sets also operated under the State Rail Authority, CityRail and Sydney Trains. Prior to their retirement, the S sets were the last class in the Sydney Trains fleet to not be air-conditioned, earning them the nicknames "Tin cans" and "Sweat Sets". They were also nicknamed "Ridgys" because of their fluted ("ridged") stainless steel panelling; they shared this nickname with similar looking K sets and C sets. The final sets were withdrawn from service in June 2019. Delivery Two manufacturers built 509 carriages, based on a largely common design: *359 carriages were built by Comeng between 1972 & 1980. They were externally distinguished by the peaked front of driving cars and a prominent line across each side of its carriages above the upper deck windows. They also had thin flutings at th ...

New South Wales American Suburban Carriage Stock
The American Suburban Carriage was a type of passenger carriage built for the New South Wales Government Railways History The American Suburban Carriage were built between 1877 and 1912 by a number of manufacturers with timber frames and truss sided body work. Due to the truss bodywork, it was difficult to cut doors in the sides of the body so doors at either end of the cars were provided with covered platforms to allow access to the carriages. They became the most numerous group of carriages built for any Australian railway system with a total of 659 carriages built. A further 196 carriages, known as Lucy Suburban Carriages were constructed between 1913 and 1916 but had steel under frames and separate bodywork. While they retained the general layout and appearance of the American Suburban Carriage, they were generally not referred to as such and 193 were later completely rebuilt for use in Electric train stock in the 1920s.The American Suburban carriages were built primarily as ...

Electric Carriage Workshops
The Electric Carriage Workshops, often abbreviated to Elcar, was the principal maintenance centre for the New South Wales Government Railways electric multiple unit fleet. Construction commenced in 1922, coinciding with the Railways in Sydney#Electrification, electrification of the Sydney network. It was located within the Chullora Railway Workshops complex on a site. It was not electrified until 1939 requiring carriages to be hauled to and from the works by steam locomotive. Elcar had a railway station that was served by worker's trains at shift changeover times. It closed in March 1994, when maintenance of CityRail's electric fleet was taken over by UGL Rail#CityRail, UGL Rail's Maintrain facility at Auburn, New South Wales, Auburn. The site has been redeveloped as the Chullora Resource Recovery Park. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Bradfield (engineer)
John Job Crew Bradfield (26 December 1867 – 23 September 1943) was an Australian engineer best known as the chief proponent of the Sydney Harbour Bridge, of which he oversaw both the design and construction. He worked for the New South Wales Department of Public Works from 1891 to 1933. He was the first recipient of an engineering doctorate from the University of Sydney, in 1924. Other notable projects with which he was associated include the Cataract Dam (completed 1907), the Burrinjuck Dam (completed 1928), and Brisbane's Story Bridge (completed 1940). The Harbour Bridge formed only one component of the City Circle, Bradfield's grand scheme for the railways of central Sydney, a modified version of which was completed after his death. He was also the designer of an unbuilt irrigation project known as the Bradfield Scheme, which proposed that remote areas of western Queensland and north-eastern South Australia could be made fertile by the diversion of rivers from North Queen ...

Railway Air Brake
A railway air brake is a railway brake power braking system with compressed air as the operating medium. Modern trains rely upon a fail-safe air brake system that is based upon a design patented by George Westinghouse on April 13, 1869. The Westinghouse Air Brake Company was subsequently organized to manufacture and sell Westinghouse's invention. In various forms, it has been nearly universally adopted. The Westinghouse system uses air pressure to charge air reservoirs (tanks) on each car. Full air pressure causes each car to release the brakes. A subsequent reduction or loss of air pressure causes each car to apply its brakes, using the compressed air stored in its reservoirs. Overview Straight air brake In the air brake's simplest form, called the ''straight air system'', compressed air pushes on a piston in a cylinder. The piston is connected through mechanical linkage to brake shoes that can rub on the train wheels, using the resulting friction to slow the train. Th ...

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 ...

Pantograph (rail)
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 ...

Overhead Line
An overhead line or overhead wire is an electrical cable that is used to transmit electrical energy to electric locomotives, trolleybuses or trams. It is known variously as: * Overhead catenary * Overhead contact system (OCS) * Overhead equipment (OHE) * Overhead line equipment (OLE or OHLE) * Overhead lines (OHL) * Overhead wiring (OHW) * Traction wire * Trolley wire This article follows the International Union of Railways in using the generic term ''overhead line''. An overhead line consists of one or more wires (or rails, particularly in tunnels) situated over rail tracks, raised to a high electrical potential by connection to feeder stations at regular intervals. The feeder stations are usually fed from a high-voltage electrical grid. Overview Electric trains that collect their current from overhead lines use a device such as a pantograph, bow collector or trolley pole. It presses against the underside of the lowest overhead wire, the contact wire. Current collectors ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
