Sydney G-Class Tram
The Sydney G-class Trams were a class of single ended cars were designed to operate either permanently coupled back to back in pairs or singly hauling a trailer on lines with reversing arrangements at the terminuses. History The G Class Trams were imported from the United States for the electrification of George Street. They were originally allocated to Ultimo Tram Depot, later moving to Newtown and Tempe. All were withdrawn by 1927. As they only had driving controls at one end, they operated in pairs. Two (124 and 125) were fitted with dual controls to operate tourist services in 1905.

American Car Company
The American Car Company was a streetcar manufacturing company based in St. Louis, Missouri, United States. It was one of the country's leading streetcar builders during the heyday of streetcar operation. Middleton, William D. (1967). ''The Time of the Trolley'', pp. 123, 420. Milwaukee: Kalmbach Publishing. . The company was founded in 1891 by William Sutton and Emil Alexander, who had previously founded the Laclede Car Company in 1883 also in St. Louis, and had both got their start working in the streetcar business at St. Louis' horsecar manufacturer, the Brownell Car Company. The American Car Company was a builder of electric powered streetcars. ACC was bought out by the J. G. Brill Company of Philadelphia in 1902. However, Brill continued to operate the American Car Co. under its own name until 1931, when it was reorganized as J. G. Brill of Missouri. In 1915, American Car built the very first Birney-type trolley, the prototype of a new design then known as the "Safety Car ...

Pantograph (rail)
A pantograph (or "pan" or "panto") is an apparatus mounted on the roof of an electric train, tram or trolley buses to collect power through contact with an overhead line. The term stems from the resemblance of some styles to the mechanical pantographs used for copying handwriting and drawings. 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. Other types of current collectors include the bow collector and the trolley pole. 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 p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volt
The volt (symbol: V) is the unit of electric potential, Voltage#Galvani potential vs. electrochemical potential, electric potential difference (voltage), and electromotive force in the International System of Units, International System of Units (SI). Definition One volt is defined as the electric potential between two points of a electrical conductor, conducting wire when an electric current of one ampere dissipates one watt of power (physics), power between those points. It can be expressed in terms of SI base units (metre, m, kilogram, kg, second, s, and ampere, A) as : \text = \frac = \frac = \frac = \text\text^2\text^. Equivalently, it is the potential difference between two points that will impart one joule of energy per coulomb of charge that passes through it. It can be expressed in terms of SI base units (metre, m, kilogram, kg, second, s, and ampere, A) as : \text = \frac = \frac = \frac = \text\text^2\text^. It can also be expressed as amperes times ohms (curre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Direct Current
Direct current (DC) is one-directional electric current, flow of electric charge. An electrochemical cell is a prime example of DC power. Direct current may flow through a conductor (material), conductor such as a wire, but can also flow through semiconductors, electrical insulation, insulators, or even through a vacuum as in electron beam, electron or ion beams. The electric current flows in a constant direction, distinguishing it from alternating current (AC). A archaism, 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 ''Electric current, current'' or ''voltage''. Direct current may be converted from an alternating current supply by use of a rectifier, which contains Electronics, electronic elements (usually) or electromechanical elements (historically) that allow current to flow only in one direction. Direct current may be converted into alt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Overhead Line
An overhead line or overhead wire is an electrical cable that is used to transmit electrical energy to electric locomotives, Electric multiple unit, electric multiple units, trolleybuses or trams. The generic term used by the International Union of Railways for the technology is ''overhead line''. It is known variously as overhead catenary, overhead contact line (OCL), overhead contact system (OCS), overhead equipment (OHE), overhead line equipment (OLE or OHLE), overhead lines (OHL), overhead wiring (OHW), traction wire, and trolley wire. An overhead line consists of one or more wires (or Overhead conductor rail, rails, particularly in tunnels) situated over rail tracks, raised to a high electrical potential by connection to feeder stations at regularly spaced intervals along the track. The feeder stations are usually fed from a High voltage, high-voltage Electricity distribution, electrical grid. Overview Electric trains that collect their current from overhead lines use a de ...

George Street, Sydney
George Street is a street in the Sydney central business district, central business district of Sydney. It was Sydney's original high street, and remains one of the busiest streets in the city centre. It connects a number of the city's most important buildings and precincts. There are more high rise buildings here than on any other street in Australia. Amongst Australia's Australian Securities Exchange#Market indices, 100 largest listed companies, more are located here than on any other street. The street begins in the north end of Sydney in The Rocks, New South Wales, The Rocks, near the Sydney Harbour Bridge, and extends to the southern end of the city, near Central railway station, Sydney, Central Station and Ultimo, New South Wales, Ultimo, where it leads into Railway Square. From here Broadway, New South Wales, Broadway is the continuation of George Street turning westwards, leading to the western suburbs as Parramatta Road.

Ultimo Tram Depot
Ultimo Tram Depot was part of the Sydney tram network. History Ultimo Tram Depot opened on 8 December 1899 adjacent to the Ultimo Power Station. It was the depot for trams operating services to Pyrmont, Ryde, and Erskineville. It was situated on the eastern side of Harris Street adjacent to the Darling Harbour railway line. The depot closed on 27 June 1953 following the decision to replace trams with buses on the Drummoyne service. The staff of 250 drivers, conductors, inspectors, and maintenance men, with 21 trams, have been transferred to other depots. The tram sheds were converted to offices in 1981 as part of the Powerhouse Museum development. The building was listed by the National Trust The National Trust () is a heritage and nature conservation charity and membership organisation in England, Wales and Northern Ireland. The Trust was founded in 1895 by Octavia Hill, Sir Robert Hunter and Hardwicke Rawnsley to "promote the ... in 1997. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tempe Bus Depot
Tempe Bus Depot (formerly Tempe Tram Depot) is a bus depot in the Sydney suburb of Tempe. It is currently operated by Transit Systems. The depot survived the closure of Sydney's former tram network and provided storage for the buses that replaced the trams. History Tempe Tram Depot opened on 15 September 1912 as an eighteen road depot on the corner of the Princes Highway and Gannon Street, Tempe. It served the Cooks River, Marrickville and Dulwich Hill lines. It closed on 20 November 1954 to become a bus depot, that in turn closed in January 1992. The tramshed and outlying offices were leased in 1986 to the Sydney Bus Museum, formally opening in April 1988. The forecourt was used to store withdrawn State Transit buses. The Sydney Bus Museum relocated to Leichhardt in 2010, with the depot refurbished and reopened as a bus depot for Metrobus vehicles in 2010 but was subsequently also used for other buses. As part of the contracting out of region 6, operation of Tempe depot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
