List Of British Rail Unbuilt Locomotive Classes
There have been a number of TOPS class numbers assigned to proposed locomotives in the UK 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 Class 14. 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 Class 60. Type 4 locomotives *Class 41 – The third use of Class 41 was for a proposed class of Class 60 locomotives with 2,500 hp engines in the early 1990s. *Class 48 – The second use of Class 48 was a proposal for a new class of locomotive for the 1990s, with gearing differences for slower freight work or higher speed loco-hauled for InterCity or parcels trains. The proposal included using proven technology for e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 use ...

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 British Rail Class 71, Class 71 locomotives in the late 1960s. An electro-diesel locomotive is one that can operate either from an Railway electrification system, electrical supply, such as Overhead line, 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) locomotives were built in 1958 at the British Rail works in Doncaster Works, Doncaster. Ten of these were deemed surplus to requirements and placed in storage in 1964. The work to convert these to electro-diesels was originally to have taken place at the Southern Region works at Eastleigh, but their involvement in new build EMUs for the Bournemouth electrification meant that Crewe Works was c ...

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 betw ...

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, Manchester, Liverpool 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 approx. and was opened from 1837 to 1881. 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 Urban rail in the United Kingdom, suburban railway systems in London, Coventry, Birmingham, Manchester, Liverpool and Glasgow, with many more smaller commuter stations, as well as providing li ...

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 mean ... [...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, electric multiple units, trolleybuses or trams. The generic term used by the International Union of Railways for the technology is ''overhead line''. It is known variously as overhead catenary, overhead contact line (OCL), overhead contact system (OCS), overhead equipment (OHE), overhead line equipment (OLE or OHLE), overhead lines (OHL), overhead wiring (OHW), traction wire, and trolley wire. 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 regularly spaced intervals along the track. 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 unde ...

British Rail Class 58
The British Rail Class 58 is a class of Co-Co locomotives, 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 railfan, rail enthusiasts. Their design represented a major departure from British conventions of construction; amongst the innovations was the adoption of the American practice of Modular design, 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, DB Cargo UK, 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 British Rail locom ...

British Rail Class 88
The British Rail Class 88 is a type of mainline mixed traffic electro-diesel locomotive manufactured by Vossloh España/Stadler Rail Valencia 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 , Vossloh'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 Class 68, considerable similarities are shared between the two locomotives, amounting to roughly 70per cent 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 ...

British Rail Class 73
The British Rail Class 73 is a British electro-diesel locomotive. This type is unusual in that it can operate on the Southern Region's 650 / 750 V DC third rail power supply, or an onboard diesel engine to allow it to be used on non-electrified routes. This makes it very versatile, although the diesel engine produces less power than is available from the third-rail power supply, so the locomotives are rarely used outside of the former Southern Region of British Railways, Southern Region of British Rail. It is one of the first bi-mode locomotives ever built. Following the withdrawal and scrapping of the more powerful British Rail Class 74, Class 74 bi-mode locomotives in 1977, the Class 73 was unique on the British railway network until the introduction of the British Rail Class 88, Class 88 bi-mode locomotives in 2017. Ten locomotives have been scrapped. History The Southern Railway (UK), Southern Railway's expanding third rail electric passenger network (which had begu ...

Locomotives
A locomotive is a rail vehicle that provides the motive power for a train. Traditionally, locomotives pulled trains from the front. However, push–pull operation has become common, and in the pursuit for longer and heavier freight trains, companies are increasingly using distributed power: single or multiple locomotives placed at the front and rear and at intermediate points throughout the train under the control of the leading locomotive. 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 used in 1814 to distinguish between self-propelled and stationary steam engines. Classifications Prior to locomotives, the motive force for railways had been generated by various lower-technology methods such as human power, horse power, gravity or stationary engines that drove cable systems. Few such systems are sti ... [...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, includi ...

British Rail Class 55
The British Rail Class 55, also known as a Deltic, or English Electric List of British Rail power classifications#Type 5, Type 5, is a class of diesel locomotive built in 1961 and 1962 by English Electric for British Railways. Twenty-two locomotives were built, designed for the high-speed express passenger services on the East Coast Main Line (ECML) between Edinburgh Waverley railway station, Edinburgh and . They gained the name "Deltic" from the prototype locomotive, British Rail DP1, 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 in 1961, 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 , and introduced the first regular 100 mph diesel passenger service to Britain, they were however capable of higher speeds than this, and often exceeded their official max ...
