Sydney D-Class Tram
The D-class trams were a class of single bogie Californian Combination type trams operated on the Sydney tram network with open cross benches at the ends and a saloon in the centre. History In 1896, Clyde Engineering delivered car 123 with an elliptical roof. The 24 others numbered 93-121 had a clerestory roof and were built by Clyde Engineering and Ritchie Brothers in 1899. The composite design and terminology was adapted from a popular style of car tram operating in California. They were introduced to give more room for smokers who were previously confined to car entrances. They were four wheel cars, seating capacity being originally 32, later being increased to 34. The last was withdrawn in 1925. Some were converted to track scrubbers with one sold to Brisbane. Preservation Two have been preserved: *102 at the Sydney Tramway Museum, converted to track scrubber in 1930 and renumbered 134s, operational, was used as a track scrubber on the Wentworth Park light rail line in 199 ...

The Spit, New South Wales
The Spit is an urban locality in the suburb of Mosman in Sydney, New South Wales, Australia. The Aboriginal word for The Spit is ''Burra Bra''. The Spit is located in the local government area of the Municipality of Mosman and is part of the Lower North Shore. Landmarks The Spit protrudes off Beauty Point and is home to the Spit Bridge, a bascule bridge opened in 1958 over Middle Harbour. The bridge opens at set times to allow yachts with high masts to pass. The Spit is the site of the Middle Harbour Yacht Club and a marina. History From as early as 1834, a ferry operated by Barney Kearns carried passengers across the waters of Middle Harbour. From the 1850s, a punt operated by Peter Ellery, carried passengers across for sixpence and horse-drawn vehicles were charged 1s 6d. If the horses swam across, there was a reduction of sixpence. In 1889, it was replaced by a government steam punt. A wooden bridge was opened in 1924 after the electric tram lines were extended to the Sp ...

Clyde Engineering
Clyde Engineering was an Australian manufacturer of locomotives, rolling stock, and other industrial products. It was founded in September 1898 by a syndicate of Sydney businessmen buying the Granville factory of timber merchants Hudson Brothers. The company won contracts for railway rolling stock, a sewerage system, trams and agricultural machinery. In 1907 it won its first contract for steam locomotives for the New South Wales Government Railways. By 1923 it had 2,200 employees. After contracting during the depression it became a major supplier of munitions during World War II. In 1950 it was awarded the first of many contracts for diesel locomotives by the Commonwealth Railways after it was appointed the Australian licensee for Electro-Motive Diesel products. Apart from building locomotives and rolling stock, Clyde Engineering diversified into telephone and industrial electronic equipment, machine tools, domestic aluminium ware, road making and earth making equipmen ...

Ritchie Brothers
Ritchie Brothers was an Australian railway rolling stock and tram manufacturer based in the Sydney suburb of Auburn. History In 1857, Robert Ritchie took over the blacksmith business of Joseph Whiting of Parramatta. In 1876, Ritchie was awarded a contract by the Government of New South Wales for 150 wagons. In 1882, the business relocated to Marion Street, Auburn. Ritchie Brothers built carriages for the New South Wales Government Railways including American suburban carriages, Bradfield suburban, Silver City Comet, 500 class trailers and 72 foot carriages. It also built D and N class trams for the Sydney tram network.

Trolley Pole
A trolley pole is a tapered cylindrical pole of wood or metal, used to transfer electricity from a "live" (electrified) overhead wire to the control and the electric traction motors of a tram or trolley bus. It is a type of current collector. The use of overhead wire in a system of current collection is reputed to be the 1880 invention of Frank J. Sprague, but the first working trolley pole was developed and demonstrated by Charles Van Depoele, in autumn 1885. Middleton, William D. (1967). ''The Time of the Trolley'', pp. 63–65, 67. Milwaukee: Kalmbach Publishing. . Etymology The term "trolley", also used to describe the pole or the passenger car using the trolley pole, is derived from the grooved conductive wheel attached to the end of the pole that "trolls" the overhead wire. The term "trolley" predates the invention of the trolley pole. The earliest electric cars did not use a pole, but rather a system in which each tramcar dragged behind it an overhead cable connected ...

Volt
The volt (symbol: V) is the unit of electric potential, electric potential difference (voltage), and electromotive force in the International System of Units (SI). It is named after the Italian physicist Alessandro Volta (1745–1827). Definition One volt is defined as the electric potential between two points of a conducting wire when an electric current of one ampere dissipates one watt of power between those points. 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 ( m, kg, second, s, and ampere, A) as : \text = \frac = \frac = \frac. It can also be expressed as amperes times ohms (current times resistance, Ohm's law), webers per second (magnetic flux per time), watts per ampere (power per current), or joules per coulomb (energy per charge), which is also equivalent to electronvolts per elementary charge: : \text = \tex ...

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 ...

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] |
Trams In Sydney
The Sydney tramway network served the inner suburbs of Sydney, Australia from 1879 until 1961. In its heyday, it was the largest in Australia, the second largest in the Commonwealth of Nations (after London), and one of the largest in the world. The network was heavily worked, with about 1,600 cars in service at any one time at its peak during the 1930s (cf. about 500 trams in Melbourne today). Patronage peaked in 1945 at 405 million passenger journeys. Its maximum street trackage totalled 291 km (181 miles) in 1923.

Trams In Brisbane
The Brisbane tramway network served the city of Brisbane, Australia, between 1885 and 1969. It ran on standard gauge track. The electric system was originally energised to 500 volts, and subsequently increased to 600 volts. All tramcars built in Brisbane up to 1938 had an open design. This proved so popular, especially on hot summer nights, that the trams were used as fundraisers and often chartered right up until the last service by social groups. Most trams operated with a two-person crew – a driver (or motorman) and a conductor, who moved about the tram collecting fares and issuing tickets. The exceptions to this arrangement were on the Gardens line (Lower Edward Street) where the short duration of the trip meant it was more effective for passengers to simply drop their fare into a fare box as they entered the tram; and the "one man cars" which operated in the early 1930s (see below). The peak year for patronage was in 1944–45 when almost 160 million passengers were carr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sydney Tramway Museum
The Sydney Tramway Museum (operated by the South Pacific Electric Railway) is Australia's oldest tramway museum and the largest in the southern hemisphere. It is located at Loftus, New South Wales, Loftus in the southern suburbs of Sydney.
