1′C1′
Rigid-framed electric locomotives were some of the first generations of electric locomotive design. When these began the traction motors of these early locomotives, particularly with AC motors, were too large and heavy to be mounted directly to the axles and so were carried on the frame. One of the initial simplest wheel arrangements for a mainline electric locomotive, from around 1900, was the 1′C1′ arrangement, in UIC classification. Some of these locomotives had their driving wheels coupled with coupling rods, as for steam locomotives. Others had individual motors for each axle, as would later become universal. By the middle of the century, the bogie arrangement for locomotives became more popular and rigid-framed locomotives are now rare, except for small shunters. 1′C1′ 1′C1′ is the UIC classification for a railway locomotive with a wheel arrangement of three coupled driving wheels, with a leading and trailing articulated pony truck.

:en:GWR 5101 Class
The GWR 5101 Class or 'Large Prairie' is a class of 2-6-2T steam locomotives of the Great Western Railway. History The 5101 Class were medium-sized tank engines used for suburban and local passenger services all over the Great Western Railway system. The class was an updated version, by Collett, of Churchward's 1903 3100/5100 Class. The original 40 members of the 3100 class were renumbered 5100 and 5111 to 5149 in 1927. The first batches of 5101s filled in the numbers 5101 to 5110 and extended the class from 5150 to 5189. They were little changed from the Churchward locomotives as they then were, but had an increased axle loading of ; the maximum permitted for the ‘Blue’ route availability. Bunkers were of the standard Collett design with greater coal capacity. The 5100 number series was exhausted in 1934, and further new locomotives were numbered from 4100. The last 20 were built after nationalisation. As both freight and passenger traffic on branch lines declin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
:en:wheel Arrangement
In rail transport, a wheel arrangement or wheel configuration is a system of classifying the way in which wheels are distributed under a locomotive. Several notations exist to describe the wheel assemblies of a locomotive by type, position, and connections, with the adopted notations varying by country. Within a given country, different notations may also be employed for different kinds of locomotives, such as steam, electric, and diesel powered. Especially in steam days, wheel arrangement was an important attribute of a locomotive because there were many different types of layout adopted, each wheel being optimised for a different use (often with only some being actually "driven"). Modern diesel and electric locomotives are much more uniform, usually with all axles driven. Major notation schemes The main notations are the Whyte notation (based on counting the wheels), the AAR wheel arrangement notation (based on counting either the axles or the bogies), and the UIC classificat ...

:en:2-6-2
Under the Whyte notation for the classification of steam locomotives, represents the wheel arrangement of two leading wheels, six coupled driving wheels and two trailing wheels. This arrangement is commonly called a Prairie. Overview The majority of American 2-6-2s were tender locomotives, but in Europe tank locomotives, described as , were more common. The first 2-6-2 tender locomotives for a North American customer were built by Brooks Locomotive Works in 1900 for the Chicago, Burlington and Quincy Railroad, for use on the Midwestern prairies. The type was thus nicknamed the Prairie in North American practice. This name was often also used for British locomotives with this wheel arrangement. As with the 2-10-2, the major problem with the 2-6-2 is that these engines have a symmetrical wheel layout, with the centre of gravity almost over the centre driving wheel. The reciprocation rods, when working near the centre of gravity, induce severe side-to-side nosing which results in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
:en:Ferrovia Della Valtellina
The Ferrovia della Valtellina (Valtellina railway) is a railway line in Italy that runs from Lecco to Valtellina and Valchiavenna. It was opened in 1894 and electrified on the three-phase system in 1902. It is now electrified at 3 kV direct current and operated by Trenord. History The line was built in stages between 1885 and 1894. Two large railway companies dominated the area at the time. They were the Rete Adriatica (Adriatic network) and the Rete Mediterranea (Mediterranean network). with the opening of the Colico-Bellano section, on 1 August 1894 a complete railway service started. Electrification The Valtellina railway is notable for being an early user of electric traction. It was the first in Italy and the first in the world to use high-voltage three-phase alternating current for rail traction. On 15 October 1902 the electrification began on the Lecco-Colico-Chiavenna and Colico-Sondrio sections with overhead power lines at 3,000 V, 15 Hz. The frequency was later ...

:en:BR Standard Class 2 2-6-2T
The British Railways standard class 2 2-6-2T was a class of steam locomotive, one of the standard classes of the 1950s. Design and construction The class was designed at Derby Works and introduced in 1953. The design derived from the LMS Ivatt Class 2 2-6-2T which BR had built after nationalisation. Modifications were made to the Ivatt design including a reduced cab to reduce the loading gauge and some standard fittings. BR classified them 2MT, emphasising a mixed-traffic role. As most services which required 2MT 2-6-2Ts were already served by the 130 Ivatt engines, B.R. only ordered 30 engines, which eliminated pre-grouping steam locomotives as much as possible on local services. The first 20 engines were outshopped at Crewe Works, and intended for use on ex-London Midland and Scottish Railway routes, then known as the London Midland Region. The second batch, this time built at Darlington Works, and were also the final steam locomotives built at Darlington were numbered 840 ...

:en:railway Turntable
In rail terminology, a railway turntable or wheelhouse is a device for turning railway rolling stock, usually locomotives, so that they can be moved back in the direction from which they came. Naturally, it is especially used in areas where economic considerations or a lack of sufficient space have served to weigh against the construction of a turnaround wye. In the case of steam locomotives, railways needed a way to turn the locomotives around for return trips as their controls were often not configured for extended periods of running in reverse and in many locomotives the top speed was lower in reverse motion. In the case of diesel locomotives, though most can be operated in either direction, they are treated as having "front ends" and "rear ends" (often determined by reference to the location of the crew cab). When a diesel locomotive is operated as a single unit, the railway company often prefers, or requires, that it be run "front end" first. When operated as part of a mul ...

:en:dieselisation
Dieselisation (US: dieselization) is the process of equipping vehicles with a diesel engine or diesel engines. It can involve replacing an internal combustion engine powered by petrol (gasoline) fuel with an engine powered by diesel fuel, as occurred on a large scale with trucks, buses, farm tractors, and building construction machinery after the Second World War. Alternatively it can involve replacing the entire plant or vehicle with one that is diesel-powered; the term commonly describes the generational replacement between the 1930s and the 1970s of railway steam locomotives with diesel locomotives, and associated facilities. Water transport The Two-stroke diesel engine for marine applications was introduced in 1908 and remains in use today. It is the most efficient prime mover to date, models such as the Wärtsilä-Sulzer RTA96-C offer a thermal efficiency of 50% and over 100,000 horsepowers. First steps towards conversions using diesel engines as means of propulsion (on sm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
