List Of British Rail Unbuilt Locomotive Classes
There have been a number of TOPS class numbers assigned to proposed locomotives that have not been built for one reason or another. Diesel locomotives Type 1 locomotives *Class 18 - A proposed new Type 1 locomotive proposed in the mid 1980s. A 1988 proposal was for a 6-wheeled 800 hp locomotive with a maximum speed of 50 mph, similar in concept to British Rail Class 14, Class 14.Locomotive Rivals from Across the Pond. D. Clough. Rail (magazine), issue 805, Jul-Aug 2016. No prototype was constructed. Type 3 locomotives *Class 38 - Projected classification for new generation of Type 3 freight locomotives in the 1980s. The Class 38 was dropped in favour of the British Rail Class 60, Class 60. Type 4 locomotives *Class 41 - The third use of British Rail Class 41 (Warship Class), Class 41 was for a proposed class of British Rail Class 60, Class 60 locomotives with 2,500 hp engines in the early 1990s. *Class 48 - The second use of British Rail Class 48, Class 48 was a proposal for ...

TOPS
Total Operations Processing System (TOPS) is a computer system for managing railway locomotives and rolling stock, known for many years of use in the United Kingdom. TOPS was originally developed between the Southern Pacific Railroad (SP), Stanford University and IBM as a replacement for paper-based systems for managing rail logistics. A jointly-owned consultancy company, ''TOPS On-Line Inc.'', was established in 1960 with the goal of implementing TOPS, as well as selling it to third parties. Development was protracted, requiring around 660 man-years of effort to produce a releasable build. During mid-1968, the first phase of the system was introduced on the SP, and quickly proved its advantages over the traditional methods practiced prior to its availability. In addition to SP, TOPS was widely adopted throughout North America and beyond. While it was at one point in widespread use across many of the United States railroads, the system has been perhaps most prominently used ...

British Rail Class 74
The British Rail Class 74 was an electro-diesel locomotive that operated on the Southern Region of British Railways, rebuilt from redundant Class 71 locomotives in the late 1960s. An electro-diesel locomotive is one that can operate either from an electrical supply, such as overhead catenary or (in this case) an energised third rail, or from an onboard diesel engine. All were withdrawn between June 1976 and December 1977, and scrapped between 1977 and 1981. History Twenty-four British Rail Class 71 (pre-TOPS type HA) were built in 1958 at the British Rail works in Doncaster and in 1964 ten were deemed surplus to requirements, withdrawn from service and placed in storage. The Southern Region was highly impressed with the "little-ED" JA & JB/class 73 locomotives and were keen to see a higher power locomotive with the same flexibility. In 1965, discussions were opened with English Electric (builders of the production JB/Class 73) to produce a high powered electro-diesel. Orig ...

InterCity 250
The InterCity 250 was an electric railway project undertaken by British Rail in the late 1980s. The InterCity 250 train would have consisted of a Class 93 electric locomotive, nine Mark 5 coaches and a Mark 5 Driving Van Trailer operating in a push-pull formation. The British Rail project was cancelled in July 1992. History In 1985, work began to fully electrify the East Coast Main Line (ECML). This project, which saw the line fitted with overhead wires between London King's Cross and Edinburgh Waverley, took five years to complete. At the same time, a new generation of rolling stock was introduced, with the Class 91 electric locomotives combined with the Mark 4 coaching stock to form InterCity 225 sets – so called because the Class 91 locomotives had a top speed of 225 km/h (140 mph). Upon the completion of the ECML project, British Rail turned to the West Coast Main Line (WCML). This had been electrified in several stages over a fifteen-year period between 19 ...

West Coast Main Line
The West Coast Main Line (WCML) is one of the most important railway corridors in the United Kingdom, connecting the major cities of London and Glasgow with branches to Birmingham, Liverpool, Manchester and Edinburgh. It is one of the busiest mixed-traffic railway routes in Europe, carrying a mixture of intercity rail, regional rail, commuter rail and rail freight traffic. The core route of the WCML runs from London to Glasgow for and was opened from 1837 to 1869. With additional lines deviating to Northampton, Birmingham, Manchester, Liverpool and Edinburgh, this totals a route mileage of . The Glasgow–Edinburgh via Carstairs line connects the WCML to Edinburgh, however the main London–Edinburgh route is the East Coast Main Line. Several sections of the WCML form part of the suburban railway systems in London, Coventry, Birmingham, Liverpool, Manchester and Glasgow, with many more smaller commuter stations, as well as providing links to more rural towns. It is one of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Rail Class 93 (InterCity 250)
British Rail Class 93 is the traction classification assigned to the electric locomotives that were to enter service as part of British Rail (BR)'s ''InterCity 250'' project on the West Coast Main Line (WCML). They would have been capable of travelling at up to , and powering a push-pull train of up to nine Mark 5 coaches and a driving van trailer (DVT), similar to the '' InterCity 225'' sets. The locomotives would have been derived from the Class 91 locomotives that entered service on the East Coast Main Line in 1989, and would thus have traced a lineage back to the Advanced Passenger Train (APT) that was planned to run on the WCML more than a decade earlier. Tenders to construct the locomotives and rolling stock were issued in March 1991, with an expected in service date of 1995; it was envisaged that up to 30 complete trains would be initially required, with a total cost estimated at £380 million. However, the cancellation of the InterCity 250 project in July 1992 mea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Overhead Wire
An overhead line or overhead wire is an electrical cable that is used to transmit electrical energy to electric locomotives, trolleybuses or trams. It is known variously as: * Overhead catenary * Overhead contact system (OCS) * Overhead equipment (OHE) * Overhead line equipment (OLE or OHLE) * Overhead lines (OHL) * Overhead wiring (OHW) * Traction wire * Trolley wire This article follows the International Union of Railways in using the generic term ''overhead line''. An overhead line consists of one or more wires (or rails, particularly in tunnels) situated over rail tracks, raised to a high electrical potential by connection to feeder stations at regular intervals. The feeder stations are usually fed from a high-voltage electrical grid. Overview Electric trains that collect their current from overhead lines use a device such as a pantograph, bow collector or trolley pole. It presses against the underside of the lowest overhead wire, the contact wire. Current collectors are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Rail Class 58
The British Rail Class 58 is a class of Co-Co diesel locomotive designed for heavy freight. The narrow body with cabs at either end led to them being given the nickname "Bone" by rail enthusiasts. Their design represented a major departure from British conventions of construction; amongst the innovations was the adoption of the American practice of modularisation. The first locomotive of the class was delivered to British Rail during early 1983 and entered service that same year. Despite expectations of a lengthy service life, during 2002, EWS decided to withdraw all examples of the type after only 19 years in service. Subsequently, 32 were hired abroad – four to the Netherlands, eight to Spain and twenty to France. A few examples have also been scrapped or have entered preservation. History During the mid-1970s, British Rail operated several different diesel locomotives that had been categorised as Type 5, these being a relatively high-powered locomotive suited to heavy ...

British Rail Class 88
The British Rail Class 88 is a type of mainline mixed traffic electro-diesel locomotive manufactured by Stadler Rail for Direct Rail Services (DRS) in the United Kingdom. The locomotive is part of the Stadler Euro Dual family. It is the first dual-mode locomotive in the UK to use the 25 kV AC electrification. Amid the fulfillment of DRS' order for the Class 68, Stadler's team proposed the development of a dual-mode locomotive that could be alternatively powered by an onboard diesel engine or via electricity supplied from overhead lines (OHLE). Having been impressed by the concept, DRS opted to place an order for ten Class 88s during September 2013. Having been developed alongside the , considerable similarities are shared between the two locomotives, amounting to roughly 70 percent of all components being shared. Testing of the first Class 88 was undertaken at the Velim Test Centre in the Czech Republic during 2016; these trials proved to be relatively smooth. Durin ...

British Rail Class 73
The British Rail Class 73 is a British electro-diesel locomotive. The type is unusual in that it can operate from the Southern Region's 650/750 V DC third-rail or an on-board diesel engine to allow it to operate on non-electrified routes. This makes it very versatile, although the diesel engine produces less power than is available from the third-rail supply so the locomotives are rarely operated outside of the former Southern Region of British Rail. Following the withdrawal and scrapping of the more powerful Class 74 electro-diesels in 1977, the Class 73 was unique on the British railway network until the introduction of the Class 88 electro-diesels in 2017. Ten locomotives have been scrapped. History The Southern Railway's expanding third rail electric passenger network (which had begun as far back as 1915) was until 1941 a purely passenger electric multiple unit (EMU) system. This was because it was necessary to have gaps in the third rail for level crossings, etc., w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Locomotives
A locomotive or engine is a rail transport vehicle that provides the motive power for a train. If a locomotive is capable of carrying a payload, it is usually rather referred to as a multiple unit, motor coach, railcar or power car; the use of these self-propelled vehicles is increasingly common for passenger trains, but rare for freight (see CargoSprinter). Traditionally, locomotives pulled trains from the front. However, push-pull operation has become common, where the train may have a locomotive (or locomotives) at the front, at the rear, or at each end. Most recently railroads have begun adopting DPU or distributed power. The front may have one or two locomotives followed by a mid-train locomotive that is controlled remotely from the lead unit. __TOC__ Etymology The word ''locomotive'' originates from the Latin 'from a place', ablative of 'place', and the Medieval Latin 'causing motion', and is a shortened form of the term ''locomotive engine'', which was first ...

British Rail Class 55
The British Rail Class 55, also known as a Deltic, or English Electric type 5, is a class of diesel locomotive built in 1961 and 1962 by English Electric for British Railways. They were designed for the high-speed express passenger services on the East Coast Main Line (ECML) between Edinburgh and . They gained the name "Deltic" from the prototype locomotive, DP1 ''Deltic'' (the running number DP1 was never carried), which in turn was named after its Napier Deltic power units. At the time of their introduction into service, the Class 55s were the most powerful single-unit diesel locomotives in the world, with a power output of . They had an official maximum speed of , however this was frequently exceeded, especially in their later years of service, with speeds of up to , being recorded on level gradients, and up to whilst descending Stoke Bank. Twenty-two locomotives were built, which were used for express passenger services on the ECML, particularly from London to and Edinburg ...

British Rail Class 50
The British Rail Class 50 is a class of diesel locomotives designed to haul express passenger trains at . Built by English Electric at the Vulcan Foundry in Newton-le-Willows between 1967 and 1968, the Class 50s were initially on a 10-year lease from English Electric Leasing, and were employed hauling express passenger trains on the, then non-electrified, section of the West Coast Main Line between Crewe and Scotland. Initially numbered D400–D449 and known as English Electric Type 4s, the locomotives were purchased outright by British Rail (BR) at the end of the lease and became Class 50 in the TOPS renumbering of 1973. The class gained the nickname "Hoovers" because of the noise made by the clean air plant at the No. 2 end, prior to refurbishment, which was likened to that of a vacuum cleaner, a name believed given to them by the staff at Paddington Station. Once the electrification from Crewe to Glasgow was completed the locomotives were moved to the Great Western Main Line ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
