Co-Bo
Co-Bo or Co′Bo′ is a wheel arrangement in the UIC classification system for railway locomotives. It features two uncoupled bogies. The "Co" bogie has three driven axles and the "Bo" bogie has two. The arrangement has been used to even out axle loading. The weight distribution of the locomotive depends on the power unit, the engine and generator. If these are not placed symmetrically, the weight distribution is also biased to one end. Placing three axles beneath the engine end and just two beneath the other, with the lighter ancillaries, gives more even loading per-axle. Examples Diesel The British Railways Class 28 is the first (and only) UK locomotive with a Co-Bo wheel arrangement. C-B A similar wheel arrangement, with five axles across two bogies, is also used in Japan for the Class DE10, DE11, and DE15 locomotives. As these are diesel-hydraulic locomotives, they are of C-B arrangement, not Co-Bo. A hydrodynamic transmission on the locomotive frame is driven by the ...

British Rail Class 28
The British Rail Class 28 ( Metro-Vick Type 2) diesel-electric locomotives, known variously as 'Metrovicks', 'Crossleys' or 'Co-Bos', were built under the Pilot Scheme for diesel locomotives as part of the British Railways 1955 Modernisation Plan. These Crossley-engined locomotives were one of two designs built under the Pilot Scheme to use two-stroke diesel engines, the other being the Class 23 'Baby Deltic' locomotives. The locomotives had a Co-Bo wheel arrangement (a 6-wheel bogie at one end, a 4-wheel bogie at the other) – unique in British Railways practice and uncommon in other countries, although Japan also used some C-B diesel hydraulics. The maximum tractive effort of was unusually high for a Type 2 locomotive but, as there were five (not four) driving axles, the risk of wheelslip was minimal. Origin Work had begun on the Pilot Scheme in 1954 and the first plan for 174 locomotives (all classes) had been produced by October 1954, including 20 of these Metro-Vi ...

Co-Co Locomotives
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 mec ...

Prime Mover (locomotive)
In engineering, a prime mover is an engine that converts fuel to useful work. In locomotives, the prime mover is thus the source of power for its propulsion. In an engine-generator set, the engine is the prime mover, as distinct from the generator. Definition In a diesel-mechanical locomotive, the prime mover is the diesel engine that is mechanically coupled to the driving wheels (drivers). In a diesel-electric locomotive, the prime mover is the diesel engine that rotates the main generator responsible for producing electricity to power the traction motors that are geared to the drivers. The prime mover can also be a gas turbine instead of a diesel engine. In either case, the generator, traction motors and interconnecting apparatus are considered to be the power transmission system and not part of the prime mover. A wired-electric or battery-electric locomotive has no on-board prime mover, instead relying on an external power station. Weight distribution The power unit rep ...

Engerth Locomotive
The Engerth locomotive was a type of early articulated steam locomotive designed by Wilhelm Freiherr von Engerth for use on the Semmering Railway in Austria. The distinctive feature of the Engerth design was an articulated tender as part of the main locomotive frame. Some of the weight of the tender therefore rested on the driving wheels, improving adhesion, while articulation allowed the locomotive to navigate the narrow curves of mountain railways. Designer Wilhelm von Engerth was born in Pless, Upper Silesia (Now Pszczyna, Poland) on 26 May 1814, the brother of the artist Edouard von Engerth. Initially, he studied architecture, but in 1834 he took up mechanical engineering as a profession. By the late 1850s he was the General Manager of the Imperial Austrian State Railways. Von Engerth was created a Baron (Freiherr) in 1875, and he died on 4 September 1884 in Leesdorf.Translated from the German article History Von Engerth first patented his design for an articulate ...

Thomas & Friends
''Thomas & Friends'' (originally known as ''Thomas the Tank Engine & Friends'' and later ''Thomas & Friends: Big World! Big Adventures!'') is a British children's television series that aired across 24 series from 1984 to 2021. Based on ''The Railway Series'' books by Rev. W. Awdry and his son Christopher, the series was developed for television by Britt Allcroft. The series follows the adventures of Thomas, an anthropomorphised blue steam locomotive on the fictional North Western Railway on the Island of Sodor, and several other anthropomorphised locomotives on the North Western Railway, including Edward, Henry, Gordon, James, Percy, and Toby. They work for the Fat Controller, who always wants his engines to be "really useful". In the United States, it was first broadcast along with the spin-off series ''Shining Time Station'' on PBS' PTV Park block in 1989. The rights to the series are currently owned by HIT Entertainment (a subsidiary of Mattel), which acquired Gullane En ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Railway Series
''The Railway Series'' is a series of British books about a railway known as the North Western Railway, located on the fictional Island of Sodor. There are 42 books in the series, the first published in May 1945 by the Rev. Wilbert Awdry. Twenty-five more books were written by Awdry, the final one being written in October 1972. Sixteen more were written by his son, Christopher Awdry, between September 1983 and July 2011. The series features many anthropomorphic vehicles, including Thomas the Tank Engine. Thomas became the most popular & famous character in the series and the titular character of the television series ''Thomas & Friends'' from 1984 to 2021. Many characters and stories from the books formed the basis of the children's television series. Nearly all of ''The Railway Series'' stories were based on real-life events. As a lifelong railway enthusiast, Awdry was keen that his stories should be as realistic as possible. The engine characters were mostly based upon real c ...

0-6-4
Under the Whyte notation for the classification of steam locomotives, represents the wheel arrangement of no leading wheels, six powered and coupled driving wheels on three axles, and four trailing wheels on two axles. Overview The 0-6-4 wheel arrangement appears to have only been used on tank engines and Single Fairlies. The earliest known example was the Moel Tryfan narrow gauge locomotive, built for use on the North Wales Narrow Gauge Railways. It was a Single Fairlie type, built by the Vulcan Foundry near Manchester in 1875. It was followed by the R class and S class, built by the Avonside Engine Company of England for the New Zealand Railways Department between 1878 and 1881. Usage Australia The South Australian Railways K class locomotives were introduced in 1884, designed by William Thow. They were noted to run more smoothly bunker-first. After the electrification of the Mersey Railway in England, four of its 0-6-4T locomotives were sold to J & A Brown of New South ...

Steam Locomotives
A steam locomotive is a locomotive that provides the force to move itself and other vehicles by means of the expansion of steam. It is fuelled by burning combustible material (usually coal, oil or, rarely, wood) to heat water in the locomotive's boiler to the point where it becomes gaseous and its volume increases 1,700 times. Functionally, it is a steam engine on wheels. In most locomotives, the steam is admitted alternately to each end of its cylinders, in which pistons are mechanically connected to the locomotive's main wheels. Fuel and water supplies are usually carried with the locomotive, either on the locomotive itself or in a tender coupled to it. Variations in this general design include electrically-powered boilers, turbines in place of pistons, and using steam generated externally. Steam locomotives were first developed in the United Kingdom during the early 19th century and used for railway transport until the middle of the 20th century. Richard Trevithick bui ...
