1Co-Co1
Co-Co is the wheel arrangement for diesel or electric locomotives with two six-wheeled bogies with all axles powered, with a separate traction motor per axle. The equivalent UIC classification (Europe) for this arrangement is Co′Co′, or C-C for AAR (North America). Use Co-Cos are most suited to freight work as the extra wheels give them good traction. They are also popular because the greater number of axles results in a lower axle load to the track. History The first mainline diesel-electric locomotives were of Bo-Bo arrangement. As they grew in power and weight, from 1937 the EMD E-units used an A1A-A1A layout with six axles to reduce axle load, but only four of them were powered. After WWII, the British LMS ordered two prototype locomotives with some of the first Co-Co arrangements. The first C-C design recorded was a narrow-gauge Hornsby opposed-piston Hornsby-Akroyd-engined locomotive of 1903 for the Chattenden and Upnor Railway. There was a two-speed m ...

British Rail Class D16/1
LMS No. 10000 and 10001 were the first mainline diesel locomotives built in Great Britain. They were built in association with English Electric by the London, Midland and Scottish Railway at its Derby Works, using an English Electric 1,600 hp diesel engine, generator and electrics. Under British Railways, the locomotives became British Railways Class D16/1; they were initially operated primarily on mainline express passenger services on former LMS lines, both in single and in multiple. In 1953, they were transferred to the Southern Region for comparison with Bulleid's British Rail Class D16/2 diesel locomotives. Both locomotives were withdrawn and scrapped in the 1960s. Background and design Background In March 1947, the LMS announced its intention to operate main line passenger services using diesel traction: initial specifications were for a pair of 1,600 hp locomotives with a top speed of 100 mph, capable of hauling express services such as the ''Royal S ...

British Rail Class 92
The British Rail Class 92 is a dual-voltage electric locomotive, which can run on 25 kV AC from overhead wires or 750 V DC from a third rail. It was designed specifically to operate services through the Channel Tunnel between Great Britain and France. Eurotunnel indicates the Class 92 locomotive as the reference for other locomotives which railway undertakings might want to get certified for usage in the Channel tunnel. Locomotives of this type are operated by GB Railfreight/ Europorte 2 and DB Cargo UK. In France, a number were also owned and operated by SNCF; these were classified as CC 92000 on French railways. The Class 92 was intended as a mixed-traffic locomotive both for hauling international freight trains and the ill-fated, never introduced ''Nightstar'' passenger sleeper trains though the Channel Tunnel. Since introduction, the fleet was exclusively allocated to freight; however, in March 2015, six locomotives owned by GB Railfreight have begun passenger opera ...

British Rail Class 77
The British Rail Class 77, also known as Class EM2, is a class of 1.5 kV DC, Co-Co electric locomotive. They were built by Metropolitan-Vickers in 1953–1954 for use over the Woodhead Line between Manchester and Sheffield. Description Seven locomotives of this type were constructed. They represented the first Co-Co type of overhead electric locomotive built for use in the United Kingdom. The design was based on that of the smaller Class EM1, which dated from 1941. Initially, 27 locomotives of this type had been planned, but by the early 1950s, the benefits of using the 25 kV AC system had been demonstrated, which meant that the Woodhead Line would be an isolated electric system. Consequently, the order was cut to just seven locomotives. The locomotives were initially numbered 27000-27006 and were painted in BR black livery. Construction took place at Gorton Works, Manchester with electrical equipment supplied by Metropolitan-Vickers. All seven were named after character ...

SNCF Class CC 7100
SNCF's CC 7100 class are part of a series of electric locomotives built by Alsthom. The prototype 'CC 7000' (7001 & 7002) were built in 1949 and the production series locomotives CC 7101-CC 7158 followed during 1952–1955. Two of the class are notable for setting world rail speed records: CC 7121 reaching on 21 February 1954, and CC 7107 reaching on 28/29 March 1955. History The CC 7100 class were the first SNCF high-speed locomotives in which all the axles were motorized, i.e. with powered bogies rather a rigid frame. As delivered their top speed was . The CC 7100 were contemporaries of the 2D2 9100 for express passenger service on the PLM. From the outset it was apparent that bogie locomotives represented the future and so only a third of the anticipated 2D2s were built, in favour of the CC 7100. Speed records During the 1950s, SNCF's experimental investigations into high-speed rail saw some CC 7100 class locomotives specially-modified for operation at speeds far highe ...

Electric Locomotive
An electric locomotive is a locomotive powered by electricity from overhead lines, a third rail or on-board energy storage such as a battery or a supercapacitor. Locomotives with on-board fuelled prime movers, such as diesel engines or gas turbines, are classed as diesel-electric or gas turbine-electric and not as electric locomotives, because the electric generator/motor combination serves only as a power transmission system. Electric locomotives benefit from the high efficiency of electric motors, often above 90% (not including the inefficiency of generating the electricity). Additional efficiency can be gained from regenerative braking, which allows kinetic energy to be recovered during braking to put power back on the line. Newer electric locomotives use AC motor-inverter drive systems that provide for regenerative braking. Electric locomotives are quiet compared to diesel locomotives since there is no engine and exhaust noise and less mechanical noise. The lack o ...

Coupling Rod
A coupling rod or side rod connects the driving wheels of a locomotive. Steam locomotives in particular usually have them, but some diesel and electric locomotives, especially older ones and shunters, also have them. The coupling rods transfer the power of drive to all wheels. Development Locomotion No. 1 was the first locomotive to employ coupling rods rather than chains. In the 1930s reliable roller bearing coupling rods were developed. Allowance for vertical motion In general, all railroad vehicles have spring suspension; without springs, irregularities in the track could lift wheels off the rail and cause impact damage to both rails and vehicles. Driving wheels are typically mounted so that they have around 1 inch (2.5 cm) of vertical motion. When there are only 2 coupled axles, this range of motion places only slight stress on the crank pins. With more axles, however, provision must be made to allow each axle to move vertically independently of the others without b ...

Chattenden And Upnor Railway
The Chattenden and Upnor Railway (also known as the Lodge Hill and Upnor Railway) was a narrow gauge railway serving the military barracks and depot at Upnor, Kent and associated munitions and training depots. It was preceded in the early 1870s by a temporary standard-gauge railway. The narrow gauge was built in 1885, and continued in use until the end of 1961. History Precursors The first railway at Chattenden was a standard gauge line laid by the Royal Engineers in the early 1870s. This was used to bring building materials from a wharf at Upnor to be used in the construction of the Chattenden Munitions Depot. According to a report in the issue of "Iron" dated Saturday 29 May 1875: "A detachment of non-commissioned officers and men of the Royal Engineers, commanded by Lieutenant Barker, on Saturday left the School of Military Engineering at Chatham for Upnor, where they will be quartered for some time, as they are to be employed to lay down lines of rails to connect fort ...

Hornsby-Akroyd Oil Engine
The Hornsby-Akroyd oil engine, named after its inventor Herbert Akroyd Stuart and the manufacturer Richard Hornsby & Sons, was the first successful design of an internal combustion engine using heavy oil as a fuel. It was the first to use a separate vapourising combustion chamber and is the forerunner of all hot-bulb engines, which are considered predecessors of the similar Diesel engine, developed a few years later. Early internal combustion engines were quite successful running on gaseous and light petroleum fuels. However, due to the dangerous nature of petroleum and light petroleum fuel, legal restrictions were placed on their transportation and storage. Heavier petroleum fuels, such as kerosene, were quite prevalent, as they were used for lighting, but posed specific problems when used in internal combustion engines: Oil used for engine fuel must be turned to a vapour state and remain in that state during compression. Furthermore, the combustion of the fuel must be powe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
