British Rail Class 415
The British Rail Class 415 (or 4EPB) is a suburban 750 V DC third rail electric multiple unit commissioned by the Southern Region of British Railways. Built between 1951 and 1957, it became the most numerous class on the region after the withdrawal of the 4SUBs. The final trains were withdrawn in the 1990s, replaced by Class 455, 456, 465 and 466. The British Rail designation Class 415 was applied to a group of four coach, third rail electric multiple units constructed between 1951 and 1961 and in service from 1951 to 1995. Construction The 4EPB units (4-car Electro-Pneumatic Brake) were a development of the Southern Railway (SR) 4Sub design, but incorporating electro-pneumatic brakes, unit-to-unit buckeye couplings, roller blind headcode displays in place of the stencil holders used previously, a revised front and without external doors to the driver's cab – access was via the adjacent guard's compartment. There were motor-generators for the lighting and current c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Power Car
In rail transport, the expression power car may refer to either of two distinct types of rail vehicle: *a vehicle that propels, and commonly also controls, a passenger train, potentially a multiple unit train, often as the lead vehicle; *a vehicle equipped with machinery for supplying heat or electrical power to other parts of a train. The first of these types of vehicle is closely related to the locomotive. What differentiates the locomotive and the first type of power car is their construction or use. A locomotive can be physically separated from its train and does nothing but provide propulsion and control (and heat or electricity for passenger trains). On the other hand, a power car of the first type is frequently an integral part of its train, and if the train uses distributed traction, some of the car's interior space may be used for carrying passengers or cargo. Examples United States Nearly all high speed trains use power cars, frequently at both ends. An example ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Rail Class 466
The British Rail Class 466 ''Networker (train), Networker'' are electric multiple unit passenger trains that were built by Metro-Cammell between 1993 and 1994. The units are currently operated by Southeastern (train operating company), Southeastern. Description The Class 466 EMUs were built between 1993 and 1994 by Metro-Cammell in Washwood Heath, for the Network SouthEast sector of British Rail. As part of the privatisation of British Rail, all were sold to Angel Trains. They were operated by Network SouthEast until 1996, and then by Connex South Eastern until 2003, South Eastern Trains until 2006 and Southeastern (train operating company), Southeastern to the present day. Each of these units is formed of two coaches that have dimensions of and a top speed of . Due to the units non-compliance with modern accessibility standards, since 1 January 2021 Class 466 units can only operate in multiple with British Rail Class 465, Class 465s, providing 6-car or 10-car suburban servi ...

Eastbourne
Eastbourne () is a town and seaside resort in East Sussex, on the south coast of England, east of Brighton and south of London. It is also a non-metropolitan district, local government district with Borough status in the United Kingdom, borough status. Eastbourne is immediately east of Beachy Head, the highest chalk sea cliff in Great Britain and part of the larger Eastbourne Downland Estate. The seafront consists largely of Victorian architecture, Victorian hotels, a Eastbourne Pier, pier, Congress Theatre (Eastbourne), theatre, Towner Gallery, contemporary art gallery and a Napoleonic era, Napoleonic era Eastbourne Redoubt, fort and military museum. Although Eastbourne is a relatively new town, there is evidence of human occupation in the area from the Stone Age. The town grew as a fashionable tourist resort largely thanks to prominent landowner William Cavendish, 7th Duke of Devonshire, William Cavendish, later to become the Duke of Devonshire. Cavendish appointed archite ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Railways Mark 1
British Rail Mark 1 is the family designation for the first standardised designs of railway carriages built by British Railways (BR) from 1951 until 1974, now used only for charter services on the main lines or on preserved railways. Following nationalisation in 1948, BR had continued to build carriages to the designs of the "Big Four" companies (the Great Western, Southern, London, Midland and Scottish and London and North Eastern railways), and the Mark 1 was intended to be the standard carriage design for use across all lines, incorporating the best features of each of the former companies' designs. It was also designed to be much stronger than previous designs, to provide better protection for passengers in the event of a collision or derailment. The Mark 1 coaches were built in two distinct tranches: the early vehicles (1951–1960) and, from 1961 onwards, the "Commonwealth" stock – so named on account of their bogies, which were a variant of the bogie designed by th ...

Eastleigh Railway Works
Eastleigh Works is a locomotive, carriage and wagon building and repair facility in the town of Eastleigh, in the county of Hampshire in England. History LSWR The London and South Western Railway (LSWR) opened a carriage and wagon works at Eastleigh in 1891. In 1903, the Chief Mechanical Engineer, Dugald Drummond, oversaw the construction of a large motive power depot in the town; replacing the existing maintenance and repair shops at Northam, Southampton. In January 1910, locomotive building was likewise transferred to the new workshops at Eastleigh from Nine Elms in London. The first locomotives built at Eastleigh were the two S14 delivered in September 1910, and these were followed by Eastleigh's first tender locomotives, the five P14 , delivered between October 1910 and February 1911. Among the other locomotives produced by the LSWR under Drummond at Eastleigh, were the M7 0-4-4 tank engines, the T14 4-6-0, and D15 4-4-0, classes. Following the appointment of R ...

Jig (tool)
A jig is a type of custom-made tool used to control the location and/or motion of parts or other tools. Description A jig's primary purpose is to provide repeatability, accuracy, and interchangeability in the manufacturing of products.. An example of a jig is when a key is duplicated; the original is used as a jig so the new key can have the same path as the old one. Since the advent of automation and computer numerical controlled (CNC) machines, jigs are often not required because the tool path is digitally programmed and stored in memory. Jigs may be made for reforming plastics. Jigs or templates have been known long before the industrial age. There are many types of jigs, and each one is custom-tailored to do a specific job. Drill jig A ''drill jig'' is a type of jig that expedites repetitive hole center location on multiple interchangeable parts by acting as a template to guide the twist drill or other boring device into the precise location of each intended hole cen ...

Oliver Bulleid
Oliver Vaughan Snell Bulleid Commander of the Order of the British Empire, CBE (19 September 1882 – 25 April 1970) was a British railway and mechanical engineer best known as the Chief Mechanical Engineer (CME) of the Southern Railway (UK), Southern Railway between 1937 and the 1948 nationalisation, developing many well-known locomotives. Early life and Great Northern Railway He was born in Invercargill, New Zealand, to William Bulleid and his wife Marian Pugh, both British immigrants. On the death of his father in 1889, his mother returned to Llanfyllin, Wales, where the family home had been, with Bulleid. In 1901, after a technical education at Accrington Grammar School, he joined the Great Northern Railway (Great Britain), Great Northern Railway (GNR) at Doncaster at the age of 18, as an apprentice under Henry Ivatt, the Chief Mechanical Engineer (CME). After a four-year apprenticeship, he became the assistant to the Locomotive Running Superintendent, and a year lat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Voltage Divider
In electronics, a voltage divider (also known as a potential divider) is a passive linear circuit that produces an output voltage (''V''out) that is a fraction of its input voltage (''V''in). Voltage division is the result of distributing the input voltage among the components of the divider. A simple example of a voltage divider is two resistors connected in series, with the input voltage applied across the resistor pair and the output voltage emerging from the connection between them. Resistor voltage dividers are commonly used to create reference voltages, or to reduce the magnitude of a voltage so it can be measured, and may also be used as signal attenuators at low frequencies. For direct current and relatively low frequencies, a voltage divider may be sufficiently accurate if made only of resistors; where frequency response over a wide range is required (such as in an oscilloscope probe), a voltage divider may have capacitive elements added to compensate load capacitance. ...

Series And Parallel Circuits
Two-terminal components and electrical networks can be connected in series or parallel. The resulting electrical network will have two terminals, and itself can participate in a series or parallel topology. Whether a two-terminal "object" is an electrical component (e.g. a resistor) or an electrical network (e.g. resistors in series) is a matter of perspective. This article will use "component" to refer to a two-terminal "object" that participates in the series/parallel networks. Components connected in series are connected along a single "electrical path", and each component has the same electric current through it, equal to the current through the network. The voltage across the network is equal to the sum of the voltages across each component. Components connected in parallel are connected along multiple paths, and each component has the same voltage across it, equal to the voltage across the network. The current through the network is equal to the sum of the currents thr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rollsign
A destination sign (North American English) or destination indicator/destination blind (British English) is a sign mounted on the front, side or rear of a public transport vehicle, such as a bus, tram/streetcar or light rail vehicle, that displays the vehicle's route number and destination, or the route's number and name on transit systems using route names. The main such sign, mounted on the front of the vehicle, usually located above (or at the top of) the windshield, is often called the headsign, most likely from the fact that these signs are located on the front, or head, end of the vehicle. Depending on the type of the sign, it might also display intermediate points on the current route, or a road that comprises a significant amount of the route, especially if the route is particularly long and its final terminus by itself is not very helpful in determining where the vehicle is going. Technology types Several different types of technology have been used for destination ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Railway Coupling
A coupling or coupler is a mechanism, typically located at each end of a rolling stock, rail vehicle, that connects them together to form a train. The equipment that connects the couplers to the vehicles is the draft gear or draw gear, which must absorb the stresses of the coupling and the acceleration of the train. Throughout the history of rail vehicles, a variety of coupler designs and types have been developed worldwide. Key design considerations include strength, reliability, easy and efficient handling, and operator safety. Automatic couplers engage automatically when the cars are pushed together. Modern versions not only provide a mechanical connection, but can also couple brake lines and data lines. Different countries use different types of couplers. While North American railroads and China use Janney couplers, railroads in the former Soviet Union use SA3 couplers and the European countries use Scharfenberg coupler, Scharfenberg and Buffers and chain coupler, screw ...
