Breydon Viaduct
Breydon Viaduct was a railway bridge across the River Yare near Great Yarmouth, Norfolk, England that was built by the Midland and Great Northern Joint Railway (M&GN). History Breydon Viaduct was built to cross the River Yare just downstream of Breydon Water and hence connect Yarmouth Beach station to the Norfolk and Suffolk Joint Railway line from Yarmouth South Town railway station. By doing so it gave passengers from the Midlands a direct link to Lowestoft. The Engineer-in-Chief of the work was Alexander Ross, the Chief Engineer of the Great Northern Railway. William E. Newman provided the mechanical and structural design and William Marriott acted as executive engineer. The bridge was long and consisted of five spans. The second span from the south rotated about its midpoint in the manner of a swing bridge to leave two passages for river traffic. This section sat on a cast iron pivot which used ball bearings which made the bridge so free running that it could be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
River Yare
The River Yare is a river in the English county of Norfolk. In its lower reaches it is one of the principal navigable waterways of The Broads and connects with the rest of the network. The river rises south of Dereham to the west to the village of Shipdham. Above its confluence with a tributary stream from Garvestone it is known as the Blackwater River.Ordnance Survey of Great Britain From there it flows in a generally eastward direction passing Barnham Broom and is joined by the River Tiffey before reaching Bawburgh. It then skirts the southern fringes of the city of Norwich, passing through Colney, Cringleford, Lakenham and Trowse. At Whitlingham it is joined by the River Wensum and although the Wensum is the larger and longer of the two, the river downstream of their confluence continues to be called the Yare. Flowing eastward into The Broads it passes the villages of Bramerton, Surlingham, Rockland St. Mary and Cantley. Just before Reedham at Hardley Cross (erect ...

William Marriott (engineer)
William Marriott (1857 – 17 November 1943) was the engineer, locomotive superintendent and traffic manager of the Midland & Great Northern Joint Railway (M&GN) Marriott was born at Basel, Switzerland where his father was a professor of English at the University of Basel. He was orphaned in 1868 and was brought to live in Bideford, receiving an education in England and on the continent. He served an apprenticeship with Ransomes & Rapier Ltd in Ipswich from 1875 to 1879 and as a draughtsman in 1880. He left Ransomes in 1881 to become an assistant engineer with Wilkinson & Jarvis Ltd completing a six-week unpaid trial period on the Yarmouth & North Norfolk Railway at Yarmouth. He was offered a permanent post which he accepted, and in 1883 he became the civil engineer and in 1884 the locomotive superintendent of the Eastern & Midlands Railway. This company was the amalgamation of all the Wilkinson & Jarvis lines in Norfolk, including both the Yarmouth & North Norfolk Railw ...

Demolished Bridges In England
Demolition (also known as razing, cartage, and wrecking) is the science and engineering in safely and efficiently tearing down of buildings and other artificial structures. Demolition contrasts with deconstruction, which involves taking a building apart while carefully preserving valuable elements for reuse purposes. For small buildings, such as houses, that are only two or three stories high, demolition is a rather simple process. The building is pulled down either manually or mechanically using large hydraulic equipment: elevated work platforms, cranes, excavators or bulldozers. Larger buildings may require the use of a wrecking ball, a heavy weight on a cable that is swung by a crane into the side of the buildings. Wrecking balls are especially effective against masonry, but are less easily controlled and often less efficient than other methods. Newer methods may use rotational hydraulic shears and silenced rock-breakers attached to excavators to cut or break through ...

Railway Viaducts In Norfolk
Rail transport (also known as train transport) is a means of transport that transfers passengers and goods on wheeled vehicles running on rails, which are incorporated in tracks. In contrast to road transport, where the vehicles run on a prepared flat surface, rail vehicles (rolling stock) are directionally guided by the tracks on which they run. Tracks usually consist of steel rails, installed on sleepers (ties) set in ballast, on which the rolling stock, usually fitted with metal wheels, moves. Other variations are also possible, such as "slab track", in which the rails are fastened to a concrete foundation resting on a prepared subsurface. Rolling stock in a rail transport system generally encounters lower frictional resistance than rubber-tyred road vehicles, so passenger and freight cars (carriages and wagons) can be coupled into longer trains. The operation is carried out by a railway company, providing transport between train stations or freight customer facilit ...

Buildings And Structures Demolished In 1962
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful). Ever since the first cave paintings, buildings have also become objects or canvasses of much artist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bridges Completed In 1903
A bridge is a structure built to span a physical obstacle (such as a body of water, valley, road, or rail) without blocking the way underneath. It is constructed for the purpose of providing passage over the obstacle, which is usually something that is otherwise difficult or impossible to cross. There are many different designs of bridges, each serving a particular purpose and applicable to different situations. Designs of bridges vary depending on factors such as the function of the bridge, the nature of the terrain where the bridge is constructed and anchored, and the material used to make it, and the funds available to build it. The earliest bridges were likely made with fallen trees and stepping stones. The Neolithic people built boardwalk bridges across marshland. The Arkadiko Bridge (dating from the 13th century BC, in the Peloponnese) is one of the oldest arch bridges still in existence and use.

Drawbridge
A drawbridge or draw-bridge is a type of moveable bridge typically at the entrance to a castle or tower surrounded by a moat. In some forms of English, including American English, the word ''drawbridge'' commonly refers to all types of moveable bridges, such as bascule bridges, vertical-lift bridges and swing bridges, but this article concerns the narrower historical definition of the term where the bridge is used in a defensive structure. As used in castles or defensive structures, drawbridges provide access across defensive structures when lowered, but can quickly be raised from within to deny entry to an enemy force. Castle drawbridges Medieval castles were usually defended by a ditch or moat, crossed by a wooden bridge. In early castles the bridge might be designed to be destroyed or removed in the event of an attack, but drawbridges became very common. A typical arrangement would have the drawbridge immediately outside a gatehouse, consisting of a wooden deck with one ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Breydon Bridge
The Breydon Bridge is a road bridge carrying the A47 in Great Yarmouth across the River Yare close to Breydon Water. It replaces the former railway Breydon Viaduct which was closed in 1953 and demolished by 1963. When built in 1985, the bridge was allocated the road number A12, which ran from London to Great Yarmouth via Lowestoft and Ipswich/ A14, in February 2017, the A12 was reallocated the number A47 as a Southern extension of the latter road, therefore leaving the Breydon Bridge carrying the number A47 which continues to Lowestoft Lowestoft ( ) is a coastal town and civil parish in the East Suffolk district of Suffolk, England.OS Explorer Map OL40: The Broads: (1:25 000) : .

Signal Box
In signal processing, a signal is a function that conveys information about a phenomenon. Any quantity that can vary over space or time can be used as a signal to share messages between observers. The '' IEEE Transactions on Signal Processing'' includes audio, video, speech, image, sonar, and radar as examples of signal. A signal may also be defined as observable change in a quantity over space or time (a time series), even if it does not carry information. In nature, signals can be actions done by an organism to alert other organisms, ranging from the release of plant chemicals to warn nearby plants of a predator, to sounds or motions made by animals to alert other animals of food. Signaling occurs in all organisms even at cellular levels, with cell signaling. Signaling theory, in evolutionary biology, proposes that a substantial driver for evolution is the ability of animals to communicate with each other by developing ways of signaling. In human engineering, signal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Double Track
A double-track railway usually involves running one track in each direction, compared to a single-track railway where trains in both directions share the same track. Overview In the earliest days of railways in the United Kingdom, most lines were built as double-track because of the difficulty of co-ordinating operations before the invention of the telegraph. The lines also tended to be busy enough to be beyond the capacity of a single track. In the early days the Board of Trade did not consider any single-track railway line to be complete. In the earliest days of railways in the United States most lines were built as single-track for reasons of cost, and very inefficient timetable working systems were used to prevent head-on collisions on single lines. This improved with the development of the telegraph and the train order system. Operation Handedness In any given country, rail traffic generally runs to one side of a double-track line, not always the same side a ...

Single Track (rail)
A single-track railway is a railway where trains traveling in both directions share the same track. Single track is usually found on lesser-used rail lines, often branch lines, where the level of traffic is not high enough to justify the cost of constructing and maintaining a second track. Advantages and disadvantages Single track is significantly cheaper to build and maintain, but has operational and safety disadvantages. For example, a single-track line that takes 15 minutes to travel through would have capacity for only two trains per hour in each direction safely. By contrast, a double track with signal boxes four minutes apart can allow up to 15 trains per hour in each direction safely, provided all the trains travel at the same speed. This hindrance on the capacity of a single track may be partly overcome by making the track one-way on alternate days, if the single track is not used for public passenger transit. Long freight trains are a problem if the passing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
