Lord's Bridge Railway Station
Lord's Bridge was a railway station on the Varsity Line which ran between Oxford and Cambridge. Situated in the north of the parish of Harlton on the western outskirts of Cambridge, it was the penultimate station before the line's eastern terminus at Cambridge. The station opened in 1862 and closed more than a century later in 1968. The site is now part of the Mullard Radio Astronomy Observatory, which includes several rail-mounted radio-telescopes. History As with the neighbouring Old North Road station, Lord's Bridge was built in open country. It was principally a stop for the local Lord of the Manor. The station's platforms were lengthened on 17 July 1907 to accommodate the longer trains running on the line. The station was equipped with a LNWR type 4 signal box from which a key could be obtained to unlock the Toft & Kingston siding to the west which handled sugar beet and hay traffic. The traffic through Lord's Bridge was to change during the Second World War when a lar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Harlton
Harlton is a village and civil parish in Cambridgeshire in the United Kingdom. The village is south-west of Cambridge and neighbours Haslingfield. History The parish of Harlton covers an area of . Its southern border is marked by the ancient track Mare Way, which runs along a raised ridge dividing it from Barrington (plus a short border with Orwell). The Bourn Brook forms its northern boundary with Comberton, and its western border with Little Eversden mostly follows the Roman Road (now the A603). Field boundaries and old water channels divide it from Haslingfield to the east. There is a very short border with Barton at its north-eastern tip. The village was an important source of mining for many centuries. The pits to the south east of the village were used to mine the clunch that was used to build Cambridge Castle in 1295. The quarry was last used for building material in 1906 and it is now a heavily wooded recreation area. The clay quarry to the south-west of the village was ...

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, signals are typi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Former London And North Western Railway Stations
A former is an object, such as a template, gauge or cutting die, which is used to form something such as a boat's hull. Typically, a former gives shape to a structure that may have complex curvature. A former may become an integral part of the finished structure, as in an aircraft fuselage, or it may be removable, being using in the construction process and then discarded or re-used. Aircraft formers Formers are used in the construction of aircraft fuselage, of which a typical fuselage has a series from the nose to the empennage, typically perpendicular to the longitudinal axis of the aircraft. The primary purpose of formers is to establish the shape of the fuselage and reduce the column length of stringers to prevent instability. Formers are typically attached to longerons, which support the skin of the aircraft. The "former-and-longeron" technique (also called stations and stringers) was adopted from boat construction, and was typical of light aircraft built until the ad ...

Beeching Axe
The Beeching cuts (also Beeching Axe) was a plan to increase the efficiency of the nationalised railway system in Great Britain. The plan was outlined in two reports: ''The Reshaping of British Railways'' (1963) and ''The Development of the Major Railway Trunk Routes'' (1965), written by Richard Beeching and published by the British Railways Board. The first report identified 2,363 stations and of railway line for closure, amounting to 55% of stations, 30% of route miles, and 67,700 British Rail positions, with an objective of stemming the large losses being incurred during a period of increasing competition from road transport and reducing the rail subsidies necessary to keep the network running. The second report identified a small number of major routes for significant investment. The 1963 report also recommended some less well-publicised changes, including a switch to the now-standard practice of containerisation for rail freight, and the replacement of some services wit ...

Goods Shed
A goods shed is a railway building designed for storing goods before or after carriage in a train. A typical goods shed will have a track running through it to allow goods wagons to be unloaded under cover, although sometimes they were built alongside a track with possibly just a canopy over the door. There will also be a door to move goods to or from road wagons and vans, this sometimes is parallel to the rail track, or sometimes on the side opposite the rail track. Inside the shed will generally be a platform and sometimes a small crane to allow easier loading and unloading of wagons. Double track Some goods sheds had more than one track. If one were not adjacent to the unloading platform then the method of working the second siding would be to first empty the wagons adjacent to the platform, and then open the doors on their far side to access those on the second track. Planks or portable bridges were normally provided for this purpose. Conversions When no longer require ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rail Gauge
In rail transport, track gauge (in American English, alternatively track gage) is the distance between the two rails of a railway track. All vehicles on a rail network must have wheelsets that are compatible with the track gauge. Since many different track gauges exist worldwide, gauge differences often present a barrier to wider operation on railway networks. The term derives from the metal bar, or gauge, that is used to ensure the distance between the rails is correct. Railways also deploy two other gauges to ensure compliance with a required standard. A ''loading gauge'' is a two-dimensional profile that encompasses a cross-section of the track, a rail vehicle and a maximum-sized load: all rail vehicles and their loads must be contained in the corresponding envelope. A ''structure gauge'' specifies the outline into which structures (bridges, platforms, lineside equipment etc.) must not encroach. Uses of the term The most common use of the term "track gauge" refers to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ryle Telescope
{{Infobox telescope The Ryle Telescope (named after Martin Ryle, and formerly known as the 5-km Array) was a linear east-west radio telescope array at the Mullard Radio Astronomy Observatory. In 2004, three of the telescopes were moved to create a compact two-dimensional array of telescopes at the east end of the interferometer. The eight antennas have now become the Arcminute Microkelvin Imager Large Array. The Ryle Telescope was an eight-element interferometer operating at 15 GHz (2cm wavelength). The elements were equatorially mounted 13-m Cassegrain antennas, on an (almost) east-west baseline. Four aerials were mounted on a 1.2 km rail track, and the others were fixed at 1.2 km intervals. Baselines between 18 m and 4.8 km were therefore available, in a variety of configurations. For high-resolution imaging, the mobile aerials were arranged along the track, to give uniform baseline coverage to 4.8 km; for low-brightness astronomy (e.g. the Sunyaev-Zel'd ...

British Railways
British Railways (BR), which from 1965 traded as British Rail, was a state-owned company that operated most of the overground rail transport in Great Britain from 1948 to 1997. It was formed from the nationalisation of the Big Four British railway companies, and was privatised in stages between 1994 and 1997. Originally a trading brand of the Railway Executive of the British Transport Commission, it became an independent statutory corporation in January 1963, when it was formally renamed the British Railways Board. The period of nationalisation saw sweeping changes in the railway. A process of dieselisation and electrification took place, and by 1968 steam locomotives had been entirely replaced by diesel and electric traction, except for the Vale of Rheidol Railway (a narrow-gauge tourist line). Passengers replaced freight as the main source of business, and one-third of the network was closed by the Beeching cuts of the 1960s in an effort to reduce rail subsidies. On privatis ...

Mustard Gas
Mustard gas or sulfur mustard is a chemical compound belonging to a family of cytotoxic and blister agents known as mustard agents. The name ''mustard gas'' is technically incorrect: the substance, when dispersed, is often not actually a gas, but is instead in the form of a fine mist of liquid droplets.https://www.acs.org/content/dam/acsorg/education/resources/highschool/chemmatters/gc-mustard-gas-personal-safety-and-natl-security.pdf Mustard gases form blisters on exposed skin and in the lungs, often resulting in prolonged illness ending in death. The active ingredient in typical mustard gas is the organosulfur compound bis(2-chloroethyl) sulfide. In the wider sense, compounds with the structural element are known as ''sulfur mustards'' and ''nitrogen mustards'', respectively. Such compounds are potent alkylating agents, which can interfere with several biological processes. History as chemical weapons As a chemical weapon, mustard gas was first used in World War I, and has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
