British Rail Class 44
The British Rail Class 44 or Sulzer Type 4 diesel locomotives were built by British Railways' Derby Works between 1959 and 1960, intended for express passenger services. They were originally numbered D1-D10 and named after British mountains, and, along with the similar Class 45 and 46 locomotives, they became known as ''Peaks''. Overview In part inspired by LMS prototypes 10000 and 10001, and by Southern Railway 10201-10203, the Class 44 diesels were some of the first big diesels commissioned for the British Rail modernisation project and were the precursors to the Class 45 and Class 46 locomotives of similar design. They were originally designed to have a Co-Co wheel arrangement, but it proved impossible to keep below the axle loading limit imposed by the British Railways Civil Engineer. A 1-Co bogie design originally used on the Southern Railway 10201 was used instead. Construction began in the summer of 1958, although the first example was not completed until April 1 ...

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 ...

Stafford D1 'Scafell Pike', The First BR Sulzer 'Peak' Class Geograph-2396440-by-Ben-Brooksbank
Stafford () is a market town and the county town of Staffordshire, in the West Midlands region of England. It lies about north of Wolverhampton, south of Stoke-on-Trent and northwest of Birmingham. The town had a population of 70,145 in the 2021 census, It is the main settlement within the larger borough of Stafford which had a population of 136,837 (2021). History Stafford means "ford" by a staithe (landing place). The original settlement was on a dry sand and gravel peninsula that offered a strategic crossing point in the marshy valley of the River Sow, a tributary of the River Trent. There is still a large area of marshland north-west of the town, which is subject to flooding and did so in 1947, 2000, 2007 and 2019. Stafford is thought to have been founded about AD 700 by a Mercian prince called Bertelin, who, legend has it, founded a hermitage on a peninsula named Betheney. Until recently it was thought that the remains of a wooden preaching cross from the time h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
25 KV, 50 Hz AC Overhead
5 (five) is a number, numeral and digit. It is the natural number, and cardinal number, following 4 and preceding 6, and is a prime number. It has attained significance throughout history in part because typical humans have five digits on each hand. In mathematics 5 is the third smallest prime number, and the second super-prime. It is the first safe prime, the first good prime, the first balanced prime, and the first of three known Wilson primes. Five is the second Fermat prime and the third Mersenne prime exponent, as well as the third Catalan number, and the third Sophie Germain prime. Notably, 5 is equal to the sum of the ''only'' consecutive primes, 2 + 3, and is the only number that is part of more than one pair of twin primes, ( 3, 5) and (5, 7). It is also a sexy prime with the fifth prime number and first prime repunit, 11. Five is the third factorial prime, an alternating factorial, and an Eisenstein prime with no imaginary part and real part of the for ...

Intercooler
An intercooler is a heat exchanger used to cool a gas after compression. Often found in turbocharged engines, intercoolers are also used in air compressors, air conditioners, refrigeration and gas turbines. Internal combustion engines Most commonly used with turbocharged engines, an intercooler is used to counteract the heat of compression and heat soak in the pressurised intake air. By reducing the temperature of the intake air, the air becomes denser (allowing more fuel to be injected, resulting in increased power) and less likely to suffer from pre-ignition or knocking. Additional cooling can be provided by externally spraying a fine mist onto the intercooler surface, or even into the intake air itself, to further reduce intake charge temperature through evaporative cooling. Intercoolers can vary dramatically in size, shape and design, depending on the performance and space requirements of the system. Many passenger cars use either ''front-mounted intercoolers'' l ...

Multiple Working
On the UK rail network, multiple working is where two or more traction units (locomotives, diesel multiple-units or electric multiple-units) are coupled together in such a way that they are all under the control of one driver (multiple-unit train control). If the front locomotive of a pair in multiple has failed the driver can still control the rear locomotive for as long as air and electricity supplies are available on the failed locomotive. In tandem is when more than one diesel or electric locomotive are hauling a single train and under the control of a driver on each locomotive. Locomotives In the early days of diesel locomotives in the 1960s, locomotives worked within their class (i.e. two locomotives of the same class could work together but not with other classes). Locomotives from different manufacturers had varying methods of controlling engines or braking systems. If a train required more than one locomotive, an additional driver was needed, at extra expense. Si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Traction Motor
A traction motor is an electric motor used for propulsion of a vehicle, such as locomotives, electric vehicle, electric or hydrogen vehicles, elevators or electric multiple unit. Traction motors are used in electrically powered rail vehicles (electric multiple units) and other electric vehicles including electric milk floats, elevators, roller coasters, conveyors, and trolleybuses, as well as vehicles with electrical transmission systems (Diesel locomotive#Transmission types, diesel-electric locomotives, electric hybrid vehicles), and battery electric vehicles. Motor types and control DC motor, Direct-current motors with series Field coil, field windings are the oldest type of traction motors. These provide a speed-torque characteristic useful for propulsion, providing high torque at lower speeds for acceleration of the vehicle, and declining torque as speed increases. By arranging the field winding with multiple taps, the speed characteristic can be varied, allowing relatively ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electric Generator
In electricity generation, a generator is a device that converts motive power (mechanical energy) or fuel-based power (chemical energy) into electric power for use in an external circuit. Sources of mechanical energy include steam turbines, gas turbines, water turbines, internal combustion engines, wind turbines and even hand cranks. The first electromagnetic generator, the Faraday disk, was invented in 1831 by British scientist Michael Faraday. Generators provide nearly all of the power for electric power grids. In addition to electromechanical designs, photovoltaic and fuel cell powered generators utilize solar power and hydrogen-based fuels, respectively, to generate electrical output. The reverse conversion of electrical energy into mechanical energy is done by an electric motor, and motors and generators have many similarities. Many motors can be mechanically driven to generate electricity; frequently they make acceptable manual generators. Terminology Electromagnetic ...

Diesel Engine
The diesel engine, named after Rudolf Diesel, is an internal combustion engine in which ignition of the fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is a so-called compression-ignition engine (CI engine). This contrasts with engines using spark plug-ignition of the air-fuel mixture, such as a petrol engine (gasoline engine) or a gas engine (using a gaseous fuel like natural gas or liquefied petroleum gas). Diesel engines work by compressing only air, or air plus residual combustion gases from the exhaust (known as exhaust gas recirculation (EGR)). Air is inducted into the chamber during the intake stroke, and compressed during the compression stroke. This increases the air temperature inside the cylinder to such a high degree that atomised diesel fuel injected into the combustion chamber ignites. With the fuel being injected into the air just before combustion, the dispersion of the fuel is une ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ian Allan Publishing
Ian Allan Publishing was an English publisher, established in 1942, which specialised in transport books. It was founded by Ian Allan. In 1942 Ian Allan, then working in the public relations department for the Southern Railway at Waterloo station, decided he could deal with many of the requests he received about rolling stock by collecting the information into a book. The result was his first book, ''ABC of Southern Locomotives''. This proved to be a success, contributing to the emergence of trainspotting as a popular hobby in the UK, and leading to the formation of the company.Ian Allan…the man who launched a million locospotters ''The Railway Magazine'' issue 1174 February 1999 pages 20-27 The company grew from a small producer of books for train enthusiasts and spotters to a large transport publisher. Each year it published books covering subjects such as military and civil aviation, naval and maritime topics, buses, trams, trolleybuses and steam railways, including hi ...

Toton TMD
Toton Traction Maintenance Depot or Toton Sidings is a large traction maintenance depot located in Toton, Nottinghamshire. The TOPS depot code for the depot is TO. Before TOPS, the shed code was 16A (18A prior to 1963). Prior to the 2021 Integrated Rail Plan for the North and Midlands, the site was the proposed location of the East Midlands Hub railway station on the Leeds Branch of HS2. History The history of the development of Toton is highly associated with the history, development and decline of the coal industry in England. The Midland Railway had developed the Midland Main Line from the 1860s, and had a developing revenue from coal traffic from both the Yorkshire and Nottinghamshire coalfields to the power stations of the industrialised West Midlands. This traffic was added to by the fact that most towns also had their own gasworks, with coal delivered by rail to their own private sidings, and the rapidly developing domestic use of coal for heating and cooking.

Midland Main Line
The Midland Main Line is a major railway line in England from London to Nottingham and Sheffield in the Midlands. It comprises the lines from London's St Pancras station via Leicester, Derby/Nottingham and Chesterfield in the East Midlands. Express passenger services on the line are operated by East Midlands Railway. The line is electrified between St Pancras and Corby and the section south of Bedford forms the northern half of the Thameslink network, with a semi-fast service to Brighton and other suburban services. A northern part of the route, between Derby and Chesterfield, also forms part of the Cross Country Route operated by CrossCountry. Tracks from Nottingham to Leeds via Barnsley and Sheffield are shared with Northern. East Midlands Railway also operates regional and local services using parts of the line. The Midland Main Line is to receive a major upgrade of new digital signalling and full line electrification from London to Sheffield. HS2 is to branch onto th ...
