Annett's Key
In British, Australian, French, and Swiss railway signalling, an Annett's key is a form of trapped-key interlocking that locks levers or other items of signalling apparatus, thereby serving as a portable form of interlocking. The purpose is to prevent access from sidings to the running line without authority. When not in use, the key is normally held in an Annett's lock that is fixed to the lever or concerned apparatus. History The Annett's key takes its name from its inventor, J. E. Annett of the London, Brighton and South Coast Railway. Annett patented his design in 1875; in 1881 that patent was bought out by Saxby and Farmer. Operation In British usage, the key may be held in a locked container in the signal box that can only be opened when the corresponding signal lever is turned to ''danger'' for traffic on the running line; the lever is locked in position until the key is returned. Alternatively, the key may be attached to the train staff for the section of running l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Railway Signalling
Railway signalling (), also called railroad signaling (), is a system used to control the movement of railway traffic. Trains move on fixed rails, making them uniquely susceptible to collision. This susceptibility is exacerbated by the enormous weight and inertia of a train, which makes it difficult to quickly stop when encountering an obstacle. In the UK, the Regulation of Railways Act 1889 introduced a series of requirements on matters such as the implementation of interlocked block signalling and other safety measures as a direct result of the Armagh rail disaster in that year. Most forms of train control involve movement authority being passed from those responsible for each section of a rail network (e.g. a signalman or stationmaster) to the train crew. The set of rules and the physical equipment used to accomplish this determine what is known as the ''method of working'' (UK), ''method of operation'' (US) or ''safeworking'' (Aus.). Not all these methods require the u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trapped-key Interlocking
Trapped-key interlocking utilizes locks and keys for sequential control of equipment and machinery to ensure safe operation. Trapped-key interlocks are widely used to ensure safe access to potentially live or dangerous plant or equipment in an industrial setting. A safe sequence of operations is enabled through transfer of keys that are either trapped or released in a predetermined order. For example, a key is used to isolate a power source (circuit breaker or supply valve), this key is then released and can then be used to gain access through a gate or door to a high risk area by inserting it into an access lock. The key will then remain trapped until the gate or door is closed. A personnel or safety key can be released from the access lock, this ensures that the gate or door can not be closed and the initial key released until this personnel or safety key is returned (assuming that no duplicate keys are available). This provides increased operator safety. In 1893, French inven ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lever Frame
Mechanical railway signalling installations rely on lever frames for their operation to interlock the signals, track locks and points to allow the safe operation of trains in the area the signals control. Usually located in the signal box, the levers are operated either by the signalman or the pointsman. The world's largest lever frame is believed to have been in the Spencer Street No.1 signal box in Melbourne, Australia, which had 191 levers, but was decommissioned in 2008. The largest, currently operational, lever frame is located at Severn Bridge Junction in Shrewsbury, England, and has 180 levers; although most of them have now been taken out of use. Overview The lever frame is located in the signal box, which can be a building at ground level or a tower, separated from or connected to an existing station building. Early lever frames were also built as ''ground frames'' next to the track, without any form of shelter and were usually operated by traincrew and not p ...

Interlocking
In railway signalling, an interlocking is an arrangement of signal apparatus that prevents conflicting movements through an arrangement of tracks such as junctions or crossings. The signalling appliances and tracks are sometimes collectively referred to as an ''interlocking plant''. An interlocking is designed so that it is impossible to display a signal to proceed unless the route to be used is proven safe. Interlocking is a safety measure designed to prevent signals and points/switches from being changed in an improper sequence. For example interlocking would prevent a signal from being changed to indicate a diverging route, unless the corresponding points/switches had been changed first. In North America, the official railroad definition of interlocking is: "''An arrangement of signals and signal appliances so interconnected that their movements must succeed each other in proper sequence''". Configuration and use A minimal interlocking consists of signals, but usually ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
London, Brighton And South Coast Railway
The London, Brighton and South Coast Railway (LB&SCR; known also as the Brighton line, the Brighton Railway or the Brighton) was a railway company in the United Kingdom from 1846 to 1922. Its territory formed a rough triangle, with London at its apex, practically the whole coastline of Sussex as its base, and a large part of Surrey. It was bounded on its western side by the London and South Western Railway (L&SWR), which provided an alternative route to Portsmouth. On its eastern side the LB&SCR was bounded by the South Eastern Railway (SER)—later one component of the South Eastern and Chatham Railway (SE&CR)—which provided an alternative route to Bexhill, St Leonards-on-Sea, and Hastings. The LB&SCR had the most direct routes from London to the south coast seaside resorts of Brighton, Eastbourne, Worthing, Littlehampton and Bognor Regis, and to the ports of Newhaven and Shoreham-by-Sea. It served the inland towns and cities of Chichester, Horsham, East Grinstead and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Patent
A patent is a type of intellectual property that gives its owner the legal right to exclude others from making, using, or selling an invention for a limited period of time in exchange for publishing an enabling disclosure of the invention."A patent is not the grant of a right to make or use or sell. It does not, directly or indirectly, imply any such right. It grants only the right to exclude others. The supposition that a right to make is created by the patent grant is obviously inconsistent with the established distinctions between generic and specific patents, and with the well-known fact that a very considerable portion of the patents granted are in a field covered by a former relatively generic or basic patent, are tributary to such earlier patent, and cannot be practiced unless by license thereunder." – ''Herman v. Youngstown Car Mfg. Co.'', 191 F. 579, 584–85, 112 CCA 185 (6th Cir. 1911) In most countries, patent rights fall under private law and the patent holder ...

Saxby And Farmer
John Saxby (17 August 1821 – 22 April 1913) was an English engineer from Brighton, noted for his work in railway signalling and the invention of the interlocking system of points and signals. He was later a partner in the firm Saxby and Farmer. He is regarded as "the father of modern signalling".Saxby & Farmer on Polunnio Biography Saxby was born at Brighton on 17 August 1821 and in 1834 was apprenticed at the age of thirteen to a carpenter and joiner. In 1840 he was employed as a carpenter at the of the |
Token (railway Signalling)
In railway signalling, a token is a physical object which a train driver is required to have or see before entering onto a particular section of single track. The token is clearly endorsed with the names of the section it belongs to. A token system is more commonly used for single lines because of the greater risk of collision in the event of a mistake being made by a signaller or traincrew, than on double lines. Principle The operation of a bidirectional single track line has the hazard of two trains colliding. The simplest way to prevent such collisions is to have only one train in the section at any given time. Such a system is known as "one-engine-in-steam” (OES) or “one-train working" (OTW). This system is used on some branches of rail networks, and on heritage railways. The main disadvantage is that it restricts the number of train movements that can be made. For a larger railway system, it becomes exceptionally limiting in the level of operations that it allows, wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The English Mechanic And World Of Science
''The English Mechanic and World of Science'', commonly referred to as ''English Mechanic'', was a popular-science magazine, published weekly from 1865 to 1926, generally consisting of 24 pages. It was aimed at people interested in inventions and gadgets and new discoveries in science, technology, and mathematics. A regular chess column was also included, written by James Pierce.

Glossary Of Rail Transport Terms
Rail terminology is a form of technical terminology. The difference between the American term ''railroad'' and the international term ''railway'' (used by the International Union of Railways and English-speaking countries outside the United States) is the most significant difference in rail terminology. These and other terms have often originated from the parallel development of rail transport systems in different parts of the world. In English-speaking countries outside the United Kingdom, a mixture of US and UK terms may exist. Various global terms are presented here. Where a term has multiple names, this is indicated. The abbreviation "UIC" refers to standard terms adopted by the International Union of Railways in its official publications and thesaurus. 0–9 A B ...
