Gothic Boiler
A haycock boiler is an early form of steam locomotive boiler with a prominently raised firebox (steam engine), firebox of "Gothic arch", "haystack", or "coppernob" shape. The term haystack boiler, haystack is most commonly used, but is avoided here as it is confusingly used for three quite different forms of boiler. This particularly large outer firebox served as the Glossary of boiler terminology#Dome, steam dome and was often highly decorated with polished brass. These were popular for early railway locomotives, from 1840 to the 1850s. Haystack firebox The prominently raised firebox first appeared in 1830, in Edward Bury, Bury's 0-4-0 locomotive ''Liverpool (1830 locomotive), Liverpool''. This was the progenitor of his Bury Bar Frame locomotive, bar-frame locomotives and shared their distinctive boiler design. The inner firebox was D-shaped in plan, with a flat tubeplate. Fireboxes of this time did not yet have a brick arch and so the Bury firebox was relatively short in length ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Stephenson's Rocket
Stephenson's ''Rocket'' is an early steam locomotive of 0-2-2 wheel arrangement. It was built for and won the Rainhill Trials of the Liverpool and Manchester Railway (L&MR), held in October 1829 to show that improved locomotives would be more efficient than stationary steam engines. ''Rocket'' was designed and built by Robert Stephenson in 1829, and built at the Forth Street Works of his company in Newcastle upon Tyne. Though ''Rocket'' was by no means the first steam locomotive, it was the first to bring together several innovations to produce the most advanced locomotive of its day. It is the most famous example of an evolving design of locomotives by Stephenson that became the template for most steam engines in the following 150 years. The locomotive was preserved and displayed in the Science Museum in London until 2018, after which it was displayed at the National Railway Museum in York.

GWR Hercules Class
The Hercules Class were four broad gauge steam locomotives for the Great Western Railway. They were the first 0-6-0 locomotives, being built in 1842 by Nasmyth, Gaskell and Company. They were all withdrawn in 1870 and 1871. From about 1865, the Hercules Class locomotives became part of the Fury Class, along with the Premier Class locomotives.

GWR Leo Class
The Great Western Railway Leo Class was a class of broad gauge steam locomotives for goods train work. This class was introduced into service between January 1841 and July 1842, and withdrawn between September 1864 and June 1874. These locomotives were the first for the railway with coupled wheels as they were designed as goods locomotives, but they later found use on passenger trains too. All the class were altered to s. The locomotives were built by three different workshops, each with its own naming convention. The first three came from R and W Hawthorn and Company, who named them after strong animals. The next three were named after volcanoes by Fenton, Murray and Jackson, while the final twelve came from Rothwell and Company carrying the names of the twelve houses of the zodiac The zodiac is a belt-shaped region of the sky that extends approximately 8° north or south (as measured in celestial latitude) of the ecliptic, the Sun path, apparent path of the Sun acro ...

GWR Firefly Class
The Firefly was a class of broad gauge 2-2-2 steam locomotives used for passenger services on the Great Western Railway. The class was introduced into service between March 1840 and December 1842, and withdrawn between December 1863 and July 1879. Following the success of the Star class locomotives introduced to the Great Western Railway by Daniel Gooch, Gooch set to work to develop a new class based on ''North Star'', but with larger boilers. The result was the ''Fire Fly'', later followed by 61 similar locomotives designated the same class. From about 1865, the Fire Fly Class locomotives became part of the Priam Class, along with the Prince Class locomotives. The original Fire Fly is said to have covered the from Twyford to London Paddington in 37 minutes, an average speed of , which was unprecedented in 1840. Locomotives A to D ;''Acheron'' :1842–1866.

Locomotives Of The Great Western Railway
The first Locomotives of the Great Western Railway (GWR) were specified by Isambard Kingdom Brunel but Daniel Gooch was soon appointed as the railway's Locomotive Superintendent. He designed several different broad gauge types for the growing railway, such as the Firefly and later Iron Duke Class 2-2-2s. In 1864 Gooch was succeeded by Joseph Armstrong who brought his standard gauge experience to the workshops at Swindon. To replace some of the earlier locomotives, he put broad gauge wheels on his standard gauge locomotives and from this time on all locomotives were given numbers, including the broad gauge ones that had previously carried just names. Joseph Armstrong's early death in 1877 meant that the next phase of motive power design was the responsibility of William Dean, his assistant and successor. Dean went on to develop express 4-4-0 types, but the familiar 4-6-0s of later years were initially introduced by the next engineer, George Jackson Churchward. He was also res ...

Daniel Gooch
Sir Daniel Gooch, 1st Baronet (24 August 1816 – 15 October 1889) was an English railway locomotive and transatlantic cable engineer. He was the first Superintendent of Locomotive Engines on the Great Western Railway from 1837 to 1864 and its chairman from 1865 until his death in 1889. Between 1865 and 1885 Gooch was Conservative MP for Cricklade. Early life Gooch was born in Bedlington, Northumberland, the son of John Gooch, an iron founder, and his wife Anna Longridge. In 1831 his family moved to Tredegar Ironworks, Monmouthshire, South Wales, where his father had accepted a managerial post, and it was there that Daniel would begin training under Thomas Ellis senior, who together with Ironmaster Samuel Homfray and Richard Trevithick pioneered steam railway locomotion. Gooch wrote in his diaries "Large works of this kind are by far the best school for a young engineer to get a general knowledge of what he needs in after life." and "...I look back upon the time spent at ...

Fire Fly 6023 Didcot (2)
Fire is the rapid oxidation of a material (the fuel) in the exothermic chemical process of combustion, releasing heat, light, and various reaction products. At a certain point in the combustion reaction, called the ignition point, flames are produced. The ''flame'' is the visible portion of the fire. Flames consist primarily of carbon dioxide, water vapor, oxygen and nitrogen. If hot enough, the gases may become ionized to produce plasma. Depending on the substances alight, and any impurities outside, the color of the flame and the fire's intensity will be different. Fire in its most common form can result in conflagration, which has the potential to cause physical damage through burning. Fire is an important process that affects ecological systems around the globe. The positive effects of fire include stimulating growth and maintaining various ecological systems. Its negative effects include hazard to life and property, atmospheric pollution, and water contamination. If fi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yarmouth And Norwich Railway
The Yarmouth & Norwich Railway (Y&NR) was the earliest railway in Norfolk, England. It was formed after it became apparent that it would be a number of years before the Eastern Counties Railway would extend their railway into Norfolk. Its Act of Parliament of 18 June 1842 authorised the issue of £200,000 worth of shares to build a line between the two towns in its name, via Reedham and the Yare valley. The act laid out fees for the carriage of coal (which would arrive at Yarmouth by sea), bricks, iron, stone,fish and cotton as well as passengers. People The chairman was George Stephenson and the chief engineer was his son Robert assisted by George Parker Bidder whilst the main contractor was Morton Peto. Shareholders included Sir Edmund Henry Knowles Lacon, John Edward Lacon (banker), Charles John Palmer (solicitor) and William Hurry Palmer (shipbuilder). Opening Robert Stephenson calculated the line would take around 18 months to build at a cost of £7,000 per mile. Constr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GWR Star Class
The Great Western Railway (GWR) Star Class of 2-2-2 broad gauge steam locomotives were used for passenger train work. Designed by Robert Stephenson, the class was introduced into service between November 1838 and November 1841, and withdrawn between April 1864 and September 1871. A total of twelve Star Class locomotives were manufactured. Notably, they were given the romantic or colloquial (rather than scientific) names of astronomical bodies. By the time the last had been delivered, GWR engineer Daniel Gooch had designed and taken delivery of several of his larger Firefly Class. ''North Star'' and ''Morning Star'' * ''North Star'' (1837–1871) :''North Star'' arrived at Maidenhead Bridge station by barge on 28 November 1837; on 31 May 1838 it worked the inaugural train for the company's directors. In 1854 it was rebuilt with cylinders and the wheelbase lengthened by . It was withdrawn in 1871 but kept at Swindon, along with ''Lord of the Isles'', until 1906. It was then d ...

Long Boiler Locomotive
The Long Boiler locomotive was the object of a patent by Robert Stephenson and the name became synonymous with the pattern. Its defining feature is that the firebox is placed ''behind'' the rearmost driving axle. This gives a long boiler barrel, with long fire-tubes. There is thus a generous heating surface area, giving a boiler that is both powerful and efficient. It is generally perceived that it arose out of attempts to match the power of broad gauge locomotives within the limitations of the standard gauge of Stephenson railways. However, the patent originally arose from a problem which became apparent as trains travelled longer distances, specifically on the North Midland Railway in England around 1841, where fire tubes and smokeboxes were becoming destroyed by the heat. Experiments Experiments at the North Midland's Derby Works showed temperatures as high as , determined by placing a small cup of zinc within the smokebox beneath the chimney. Stephenson extended the boiler, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vault (architecture)
In architecture, a vault (French ''voûte'', from Italian ''volta'') is a self-supporting arched form, usually of stone or brick, serving to cover a space with a ceiling or roof. As in building an arch, a temporary support is needed while rings of voussoirs are constructed and the rings placed in position. Until the topmost voussoir, the keystone, is positioned, the vault is not self-supporting. Where timber is easily obtained, this temporary support is provided by centering consisting of a framed truss with a semicircular or segmental head, which supports the voussoirs until the ring of the whole arch is completed. Vault types Corbelled vaults, also called false vaults, with horizontally joined layers of stone have been documented since prehistoric times; in the 14th century BC from Mycenae. They were built regionally until modern times. The real vault construction with radially joined stones was already known to the Egyptians and Assyrians and was introduced into the buil ...
