British Rail Class 151
The British Rail Class 151 was a prototype class of diesel multiple unit (DMU) developed and constructed by the British railway equipment manufacturer Metro Cammell. It was designed primarily to serve as a successor to the earlier first-generation "Heritage" DMUs operated by the British Rail (BR). Development of the Class 151 commenced during 1983 in response to a specification issued by BR calling for a new generation of DMU with which to equip its fleet. Both Metro Cammell and British Rail Engineering Limited (BREL) were selected to produce prototypes of their design submissions. Accordingly, a pair of 3-car units were constructed, which entered trial service with BR during 1985. If it had emerged successful, the Class 151 would have likely become the basis of ''Sprinter'' family of DMUs that were produced during the 1980s. However, following a competitive evaluation against the rival Class 150, the type did not secure a production contract, having lost out to its BREL-built ...

Matlock Railway Station
Matlock railway station is owned by Network Rail and managed by East Midlands Railway; it serves the Derbyshire Dales town of Matlock, Derbyshire, England. The station is the terminus of both the Derwent Valley Line from and Peak Rail who operate heritage services to . Both lines are formed from portions of the Midland Railway's former main line to . Through running is technically possible but is not done in normal service. History Originally called ''Matlock Bridge'', it was opened by the Manchester, Buxton, Matlock and Midlands Junction Railway. The station saw its first passengers on 4 June 1849, when the line between Ambergate and Rowsley opened. The station buildings, designed by Sir Joseph Paxton, opened in 1850. The station master's house is now grade 2 listed. Leaving , the line immediately passes into the series of High Tor tunnels, , and long on the east side of the river, cut into the cliff side. Crossing the river and the main A6 road, the line passes throug ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

BSI Coupling
A coupling (or a coupler) is a mechanism typically placed at each end of a railway vehicle that connects them together to form a train. A variety of coupler types have been developed over the course of railway history. Key issues in their design include strength, reliability, ease of making connections and operator safety. The equipment that connects the couplings to the vehicles is the draft gear or draw gear and these must absorb the stresses of coupling and train acceleration. Nomenclature Compatible and similar couplings or couplers are frequently referred to using widely differing make, brand, or regional names, or nicknames, which can make describing standard or typical designs confusing. Dimensions and ratings noted in these articles are usually of nominal or typical components and systems, though standards and practices also vary widely with railway, region, and era. Buffers and chain The basic type of coupling on railways following the British tradition is the bu ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

British Rail Class 455
The British Rail Class 455 is an electric multiple unit passenger train built by BREL between 1982 and 1985. It is operated on suburban services in Greater London and Surrey by South Western Railway, as well as formerly by Southern. Description The Class 455 was originally to be classified as the Class 510, at which point they were planned as a 750 V DC version of the . However, as the chopper control system at the time was not considered robust enough for the electrically rougher third rail Southern Region, they were fitted with a GEC Traction camshaft control systems instead. The Class 510 designation was discarded in favour of Class 455. A total of 505 carriages were built by British Rail Engineering Limited's Holgate Road carriage works and together with 43 existing trailers from Class 508s, formed 137 four-car sets. The 455s allowed the and to be withdrawn, as well as allowing the Class 508s to be transferred to the Merseyside network for which they were original ...

Toilet
A toilet is a piece of sanitary hardware that collects human urine and feces, and sometimes toilet paper, usually for disposal. Flush toilets use water, while dry or non-flush toilets do not. They can be designed for a sitting position popular in Europe and North America with a toilet seat, with additional considerations for those with disabilities, or for a squatting posture more popular in Asia (see squat toilet). In urban areas, flush toilets are usually connected to a sewer system that leads to septic tanks in isolated areas. The waste is known as '' blackwater'' and the combined effluent including other sources is sewage. Dry toilets are connected to a pit, removable container, composting chamber, or other storage and treatment device, including urine diversion with a urine-diverting toilet. The technology used for modern toilets varies. Toilets are commonly made of ceramic (porcelain), concrete, plastic, or wood. Newer toilet technologies include dual flushing, ...

Decibel
The decibel (symbol: dB) is a relative unit of measurement equal to one tenth of a bel (B). It expresses the ratio of two values of a power or root-power quantity on a logarithmic scale. Two signals whose levels differ by one decibel have a power ratio of 101/10 (approximately ) or root-power ratio of 10 (approximately ). The unit expresses a relative change or an absolute value. In the latter case, the numeric value expresses the ratio of a value to a fixed reference value; when used in this way, the unit symbol is often suffixed with letter codes that indicate the reference value. For example, for the reference value of 1 volt, a common suffix is " V" (e.g., "20 dBV"). Two principal types of scaling of the decibel are in common use. When expressing a power ratio, it is defined as ten times the logarithm in base 10. That is, a change in ''power'' by a factor of 10 corresponds to a 10 dB change in level. When expressing root-power quantities, a change in ''ampl ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

British Rail Class 210
The British Rail Class 210 was a type of diesel-electric multiple unit (DEMU) passenger train designed and constructed by British Rail Engineering Limited's Derby Litchurch Lane Works. The Class 210 was developed during the early 1980s to be a modern replacement for the ageing 'first generation' DMUs in use on the Southern Region of British Railways, such as the Class 201 and Class 207. It was designed around a particularly ambitious set of requirements defined in a specification produced by British Rail (BR), construction of the first unit commenced during 1982. While several prototypes were built and subject to extensive testing during the 1980s, the process did not result in a production run for the type. It can be considered an alternative to, or spiritual precursor of, the highly successful ''Sprinter'' family of DMUs that were produced during the 1980s. The handful of Class 210s that were built were only operated for a few years before being withdrawn in the 1980s. At l ...

Asbestos
Asbestos () is a naturally occurring fibrous silicate mineral. There are six types, all of which are composed of long and thin fibrous crystals, each fibre being composed of many microscopic "fibrils" that can be released into the atmosphere by abrasion and other processes. Inhalation of asbestos fibres can lead to various dangerous lung conditions, including mesothelioma, asbestosis, and lung cancer, so it is now notorious as a serious health and safety hazard. Archaeological studies have found evidence of asbestos being used as far back as the Stone Age to strengthen ceramic pots, but large-scale mining began at the end of the 19th century when manufacturers and builders began using asbestos for its desirable physical properties. Asbestos is an excellent electrical insulator and is highly fire-resistant, so for much of the 20th century it was very commonly used across the world as a building material, until its adverse effects on human health were more widely acknowledged ...

British Rail Class 150
The British Rail Class 150 ''Sprinter'' is a class of diesel multiple unit passenger trains; they were developed and constructed by BREL York between 1984 and 1987 for use on regional services across the UK. The type is a second-generation design, built to more modern standards and based on BR's Mark 3 body design for longer-distance services. It was developed alongside the lower-cost ''Pacers'', which were built using bus parts, for use on short-distance services. Two prototype units were built, followed by 135 production units in two batches. Subsequently, further members of the Sprinter family were also developed and introduced to service, including the Class 155, Class 156, Class 158 and Class 159. Background By the beginning of the 1980s, British Rail (BR) was operating a large fleet of first-generation DMUs of various designs. While formulating its long-term strategy for this sector of its operations, BR planners recognised that there would be considerable costs ...

British Rail Engineering Limited
British Rail Engineering Limited (BREL) was the railway systems engineering subsidiary of British Rail. Established in 1970, the maintenance arm was split as British Rail Maintenance Limited in 1987, and the design and building of trains was privatised in 1989, purchased by the Swiss-Swedish conglomerate Asea Brown Boveri (40%), Trafalgar House (40%), and a management-employee buy-out (20%). After ABB became the sole shareholder in September 1992, it was subsumed into ABB Transportation. History BREL was established by the British Railways Board on 1 January 1970 to take over the management of its 14 rolling stock maintenance centres, including Ashford, Crewe, Derby Litchurch Lane, Derby Locomotive, Doncaster, Eastleigh, Glasgow, Horwich, Shildon, Swindon, Wolverton, and York. Ashford Works closed in 1981, Shildon in 1984, and Swindon in 1986. In 1987, Doncaster, Eastleigh, Glasgow, and Wolverton were transferred to BR Maintenance. Not all British Rail rolling stock wa ...

British Rail
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 ...

Metro Cammell
Metro-Cammell, formally the Metropolitan Cammell Carriage and Wagon Company (MCCW), was an English manufacturer of railway carriages, locomotives and railway wagons, based in Saltley, and subsequently Washwood Heath, in Birmingham. Purchased by GEC Alsthom in May 1989, the Washwood Heath factory was closed in 2005. The company designed and built trains for the railways in the United Kingdom and overseas, including the Mass Transit Railway of Hong Kong, Kowloon–Canton Railway (now East Rail line), the Channel Tunnel, and the Tyne and Wear Metro, and locomotives for Malaysia's Keretapi Tanah Melayu. Diesel and electric locomotives were manufactured for South African Railways, Nyasaland Railways, Malawi, Nigeria, Trans-Zambezi Railway and Pakistan. DMUs were supplied to Jamaica Railway Corporation and the National Railways of Mexico. The vast majority of London Underground rolling stock manufactured in mid-20th century was produced by the company. It also designed and built ...

Diesel Multiple Unit
A diesel multiple unit or DMU is a multiple-unit train powered by on-board diesel engines. A DMU requires no separate locomotive, as the engines are incorporated into one or more of the carriages. Diesel-powered single-unit railcars are also generally classed as DMUs. Diesel-powered units may be further classified by their transmission type: diesel–mechanical DMMU, diesel–hydraulic DHMU, or diesel–electric DEMU. Design The diesel engine may be located above the frame in an engine bay or under the floor. Driving controls can be at both ends, on one end, or in a separate car. Types by transmission DMUs are usually classified by the method of transmitting motive power to their wheels. Diesel–mechanical In a diesel–mechanical multiple unit (DMMU), the rotating energy of the engine is transmitted via a gearbox and driveshaft directly to the wheels of the train, like a car. The transmissions can be shifted manually by the driver, as in the great majority of first-gen ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
