Turntable (rail)
In rail terminology, a railway turntable or wheelhouse is a device for turning railway rolling stock, usually locomotives, so that they can be moved back in the direction from which they came. Naturally, it is especially used in areas where economic considerations or a lack of sufficient space have served to weigh against the construction of a turnaround wye. In the case of steam locomotives, railways needed a way to turn the locomotives around for return trips as their controls were often not configured for extended periods of running in reverse and in many locomotives the top speed was lower in reverse motion. In the case of diesel locomotives, though most can be operated in either direction, they are treated as having "front ends" and "rear ends" (often determined by reference to the location of the crew cab). When operated as a single unit, the railway company often prefers, or requires, that a diesel locomotive is run "front end" first. When operated as part of a multiple ...

Wagon Turntable
A wagon or waggon is a heavy four-wheeled vehicle pulled by draught animals or on occasion by humans, used for transporting goods, commodities, agricultural materials, supplies and sometimes people. Wagons are immediately distinguished from carts (which have two wheels) and from lighter four-wheeled vehicles primarily for carrying people, such as carriages. Animals such as horses, mules, or oxen usually pull wagons. One animal or several, often in pairs or teams may pull wagons. However, there are examples of human-propelled wagons, such as mining corfs. A wagon was formerly called a wain and one who builds or repairs wagons is a wainwright. More specifically, a wain is a type of horse- or oxen-drawn, load-carrying vehicle, used for agricultural purposes rather than transporting people. A wagon or cart, usually four-wheeled; for example, a haywain, normally has four wheels, but the term has now acquired slightly poetical connotations, so is not always used with technical c ...

Turntable At OERM
A phonograph, in its later forms also called a gramophone (as a trademark since 1887, as a generic name in the UK since 1910) or since the 1940s called a record player, or more recently a turntable, is a device for the mechanical and analogue recording and reproduction of sound. The sound vibration waveforms are recorded as corresponding physical deviations of a spiral groove engraved, etched, incised, or impressed into the surface of a rotating cylinder or disc, called a "record". To recreate the sound, the surface is similarly rotated while a playback stylus traces the groove and is therefore vibrated by it, very faintly reproducing the recorded sound. In early acoustic phonographs, the stylus vibrated a diaphragm which produced sound waves which were coupled to the open air through a flaring horn, or directly to the listener's ears through stethoscope-type earphones. The phonograph was invented in 1877 by Thomas Edison. Alexander Graham Bell's Volta Laboratory made seve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Miskolc Tiszai Railway Station
The Tiszai Railway Station, operated by Hungarian State Railways, is the larger of two railway stations of the city of Miskolc, Hungary. Despite its name, the station is not close to the river Tisza; it was named after the company that built it. History Miskolc's need for connection with other cities by railway lines arose in the 1830s. Plans were made to expand the Szolnok–Debrecen railway line towards Nyíregyháza and Miskolc, but due to the political situations of the time – there was a revolution against Habsburg rule in 1848–49 – construction was delayed until 1857. Disagreements between the railway constructing company and the local government of the city hindered work. The local government wanted the station to be built at the end of Széchenyi Street, the main street of Miskolc, approximately where the Szinvapark shopping mall stands today, and said the area that the constructing company appointed (and where the station was eventually built) was too far from the c ...

Great Western Railway
The Great Western Railway (GWR) was a British railway company that linked London with the southwest, west and West Midlands of England and most of Wales. It was founded in 1833, received its enabling Act of Parliament on 31 August 1835 and ran its first trains in 1838 with the initial route completed between London and Bristol in 1841. It was engineered by Isambard Kingdom Brunel, who chose a broad gauge of —later slightly widened to —but, from 1854, a series of amalgamations saw it also operate standard-gauge trains; the last broad-gauge services were operated in 1892. The GWR was the only company to keep its identity through the Railways Act 1921, which amalgamated it with the remaining independent railways within its territory, and it was finally merged at the end of 1947 when it was nationalised and became the Western Region of British Railways. The GWR was called by some "God's Wonderful Railway" and by others the "Great Way Round" but it was famed as the "Holiday ...

Ransomes & Rapier
Ransomes & Rapier was a major British manufacturer of railway equipment and later cranes, from 1869 to 1987. Originally an offshoot of the major engineering company Ransome's it was based at Waterside Works in Ipswich, Suffolk. Ransome's split Ransomes & Rapier was formed in 1869 when four engineers, James Allen Ransome (1806–1875), his elder son, Robert James Ransome (c.1831–1891), Richard Christopher Rapier (1836–1897) and Arthur Alec Bennett (1842–1916), left the parent firm by agreement to establish a new firm on a site on the River Orwell to continue the business of manufacturing railway equipment and other heavy works. The year before J. A. Ransome's younger son, Allen Ransome (1833–1913), founded the saw-milling machinery business, A. Ransome & Co, in Chelsea London with a foundry in Battersea. These businesses, transferred to Newark-on-Trent in 1900, led at the outset of World War I to Ransome & Marles now part of Nippon Seikō Kabushiki-kaisha. R. C. Rapier ...

Vacuum Motor
A vacuum engine (also called flame-licker engine, flame-engine, flame-dancer) derives its force from air pressure against one side of the piston, which has a partial vacuum on the other side of it. At the beginning of an outstroke, a valve in the head of the cylinder opens and admits a charge of burning gas and air, which is trapped by the closing of the valve and expands. Towards the end of the stroke the charge comes into contact with a water- or air-cooled part of the cylinder and is chilled, causing a sudden drop in pressure sufficient to suck the piston – which is open towards the crank – back on the return stroke. The valve opens again in time for the piston to expel the burnt gases before the next outstroke begins. History Some early gas engines worked on the "vacuum" or "atmospheric" principle in a similar way to the Newcomen steam engine. A mixture of gas and air was eaten by the cylinder and ignited; the mixture expanded and part of it escaped through the exhaust va ...

Vacuum Brake
The vacuum brake is a braking system employed on trains and introduced in the mid-1860s. A variant, the automatic vacuum brake system, became almost universal in British train equipment and in countries influenced by British practice. Vacuum brakes also enjoyed a brief period of adoption in the United States, primarily on narrow-gauge railroads. Their limitations caused them to be progressively superseded by compressed air systems starting in the United Kingdom from the 1970s onward. The vacuum brake system is now obsolete; it is not in large-scale usage anywhere in the world, other than in South Africa, largely supplanted by air brakes. Introduction In the earliest days of railways, trains were slowed or stopped by the application of manually applied brakes on the locomotive and in brake vehicles through the train, and later by steam power brakes on locomotives. This was clearly unsatisfactory, given the slow and unreliable response times (each brake being separately applied by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Junee Roundhouse Railway Museum
The Junee Roundhouse Railway Museum preserves the former Junee Locomotive Depot, a railway depot located on the Main Southern line in Junee, Australia. History The Junee Locomotive Depot was built by the New South Wales Government Railways when the line from Sydney opened to Junee in 1878. On 29 September 1947, a 42 road, fully covered roundhouse was completed. This was the last steam locomotive depot built by the New South Wales Government Railways. As well as being the depot for locomotives on various branch lines, it was strategically important being located half-way between Sydney and Melbourne. On 9 July 1993, the State Rail Authority closed the depot. In December 1994, Junee Council leased the roundhouse with part of it sublet to Austrac Ready Power who restored several ex State Rail Authority engines at the site as well as rebuilding engines for BHP, Port Kembla with the other part set up as a museum. Following Austrac Ready Power ceasing operations in September 2000, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
England
England is a country that is part of the United Kingdom. It shares land borders with Wales to its west and Scotland to its north. The Irish Sea lies northwest and the Celtic Sea to the southwest. It is separated from continental Europe by the North Sea to the east and the English Channel to the south. The country covers five-eighths of the island of Great Britain, which lies in the North Atlantic, and includes over 100 smaller islands, such as the Isles of Scilly and the Isle of Wight. The area now called England was first inhabited by modern humans during the Upper Paleolithic period, but takes its name from the Angles, a Germanic tribe deriving its name from the Anglia peninsula, who settled during the 5th and 6th centuries. England became a unified state in the 10th century and has had a significant cultural and legal impact on the wider world since the Age of Discovery, which began during the 15th century. The English language, the Anglican Church, and Engli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
London
London is the capital and largest city of England and the United Kingdom, with a population of just under 9 million. It stands on the River Thames in south-east England at the head of a estuary down to the North Sea, and has been a major settlement for two millennia. The City of London, its ancient core and financial centre, was founded by the Romans as '' Londinium'' and retains its medieval boundaries.See also: Independent city § National capitals The City of Westminster, to the west of the City of London, has for centuries hosted the national government and parliament. Since the 19th century, the name "London" has also referred to the metropolis around this core, historically split between the counties of Middlesex, Essex, Surrey, Kent, and Hertfordshire, which largely comprises Greater London, governed by the Greater London Authority.The Greater London Authority consists of the Mayor of London and the London Assembly.

The Roundhouse
The Roundhouse is a performing arts and concert venue situated at the Grade II* listed former railway engine shed in Chalk Farm, London, England. The building was erected in 1846–1847 by the London & North Western Railway as a roundhouse, a circular building containing a railway turntable, but was used for that purpose for only about a decade. After being used as a warehouse for a number of years, the building fell into disuse just before World War II. It was first made a listed building in 1954. It reopened after 25 years, in 1964, as a performing arts venue, when the playwright Arnold Wesker established the Centre 42 Theatre Company and adapted the building as a theatre. The large circular structure has hosted various promotions, such as the launch of the underground paper ''International Times'' in 1966, one of only two UK appearances by The Doors with Jim Morrison in 1968, and the Greasy Truckers Party in 1972. The Greater London Council ceded control of the building t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
