NCC Class S1
The Northern Counties Committee (NCC) Class S1 was a class of two-cylinder Compound locomotive, compound steam locomotives that was introduced for service on the narrow gauge railways of County Antrim in north-east Ireland. The members of the class were rebuilds of the BNCR Class S. History The Class S1 was a class of two locomotives that were rebuilt by the Northern Counties Committee, LMS (NCC) from BNCR Class S Thomas William Worsdell, Worsdell-August von Borries, von Borries two-cylinder compound locomotives. They had outside cylinders and Walschaerts valve gear with the smaller diameter high-pressure cylinder on the left and the larger low-pressure one on the right. The rebuilding was carried out to increase the coal capacity by fitting a bunker behind the cab. This was accommodated by increasing the length of the radial truck, the wheelbase and overall length of the locomotives by two feet. On the modified engines the coal capacity was nominally unaltered at one lon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northern Counties Committee
The Northern Counties Committee (NCC) was a railway that served the north-east of Ireland. It was built to Irish gauge () but later acquired a number of narrow gauge lines. It had its origins in the Belfast and Ballymena Railway which opened to traffic on 11 April 1848. The NCC itself was formed on 1 July 1903 as the result of the Midland Railway of England taking over the Belfast and Northern Counties Railway (BNCR), which the Belfast and Ballymena Railway had become. At the Railways Act 1921, 1923 Grouping of British railway companies, the Committee became part of the London, Midland and Scottish Railway (LMS). After the Transport Act 1947, nationalisation of Britain's railways in 1948 the NCC was briefly part of the British Transport Commission, which sold it to the Ulster Transport Authority (UTA) in 1949. The BNCR and its successors recognised the potential value of tourism and were influential in its development throughout Northern Ireland. They were able to develop and ...

Top Dead Centre
In a reciprocating engine, the dead centre is the position of a piston in which it is either furthest from, or nearest to, the crankshaft. The former is known as top dead centre (TDC) while the latter is known as bottom dead centre (BDC). More generally, the dead centre is any position of a crank where the applied force is straight along its axis, meaning no turning force can be applied. Many sorts of machines are crank driven, including unicycles, bicycles, tricycles, various types of machine presses, gasoline engines, diesel engines, steam locomotives, and other steam engines. Crank-driven machines rely on the energy stored in a flywheel to overcome the dead centre, or are designed, in the case of multi-cylinder engines, so that dead centres can never exist on all cranks at the same time. A steam locomotive is an example of the latter, the connecting rods being arranged such that the dead centre for each cylinder occurs out of phase with the other one (or more) cylinders ...

Railway Locomotives Introduced In 1928
Rail transport (also known as train transport) is a means of transport using wheeled vehicles running in tracks, which usually consist of two parallel steel rails. Rail transport is one of the two primary means of land transport, next to road transport. It is used for about 8% of passenger and freight transport globally, thanks to its energy efficiency and potentially high speed.Rolling stock on rails generally encounters lower frictional resistance than rubber-tyred road vehicles, allowing rail cars to be coupled into longer trains. Power is usually provided by diesel or electric locomotives. While railway transport is capital-intensive and less flexible than road transport, it can carry heavy loads of passengers and cargo with greater energy efficiency and safety. Precursors of railways driven by human or animal power have existed since antiquity, but modern rail transport began with the invention of the steam locomotive in the United Kingdom at the beginning of the 19th ...

1′B1′ N2t Locomotives
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′, 1′C1′ arrangement, in UIC classification of locomotive axle arrangements, 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 of locomotive axle arrangements, UIC classification for a railway locomotive with a wheel arrange ...

3 Ft Gauge Locomotives
3 (three) is a number, numeral and digit. It is the natural number following 2 and preceding 4, and is the smallest odd prime number and the only prime preceding a square number. It has religious and cultural significance in many societies. Evolution of the Arabic digit The use of three lines to denote the number 3 occurred in many writing systems, including some (like Roman and Chinese numerals) that are still in use. That was also the original representation of 3 in the Brahmic (Indian) numerical notation, its earliest forms aligned vertically. However, during the Gupta Empire the sign was modified by the addition of a curve on each line. The Nāgarī script rotated the lines clockwise, so they appeared horizontally, and ended each line with a short downward stroke on the right. In cursive script, the three strokes were eventually connected to form a glyph resembling a with an additional stroke at the bottom: ३. The Indian digits spread to the Caliphate in the 9th ...

Steam Locomotives Of Northern Ireland
Steam is water vapor, often mixed with air or an aerosol of liquid water droplets. This may occur due to evaporation or due to boiling, where heat is applied until water reaches the enthalpy of vaporization. Saturated or superheated steam is invisible; however, wet steam, a visible mist or aerosol of water droplets, is often referred to as "steam". When liquid water becomes steam, it increases in volume by 1,700 times at standard temperature and pressure; this change in volume can be converted into mechanical work by steam engines such as reciprocating piston type engines and steam turbines, which are a sub-group of steam engines. Piston type steam engines played a central role in the Industrial Revolution and modern steam turbines are used to generate more than 80% of the world's electricity. If liquid water comes in contact with a very hot surface or depressurizes quickly below its vapour pressure, it can create a steam explosion. Types of steam and conversions Steam is trad ...

Steam Locomotives Of Ireland
A wide variety of steam locomotives have been used on History of rail transport in Ireland, Ireland's railways. This page lists most if not all those that have been used in the Republic of Ireland and Northern Ireland. Irish railways generally followed British practice in locomotive design. The list that follows is roughly geographic (north to south) order. Northern Ireland The Ulster Transport Authority, which controlled the railways in Northern Ireland between 1948 and 1966, replaced Steam locomotive, steam haulage on passenger trains with diesel multiple units, but had only two diesel shunting locomotives, which meant a continued role for steam on freight work. Twenty-three locomotives passed to Northern Ireland Railways in 1967, but most were not used again and all had been withdrawn by 1971. Belfast and County Down Railway The Belfast and County Down Railway was founded in 1848. It absorbed the Belfast, Hollywood and Bangor Railway in 1884 and continued operating until it w ...

Steam Dome
The steam dome is a vessel fitted to the top of the boiler of a steam engine. It contains the opening to the main steam pipe and its purpose is to allow this opening to be kept well above the water level in the boiler. This arrangement acts as a simple steam separator and minimises the risk that water will be carried over to the Cylinder (locomotive), cylinders where it might cause a Hydrolock, hydraulic lock, also known as Priming (steam locomotive), priming. A steam dome should not be confused with a Sandbox (locomotive), sand dome. Railway locomotives The first locomotive with a deliberate dome added to the boiler barrel was Stephenson's 'Phoenix' an 0-2-2 for the Liverpool and Manchester Railway in 1830. Many other locomotives built from the late 1830s instead used either the haycock boiler, 'haycock' boiler, where the firebox outer casing was raised high above the main part of the boiler, forming a steam dome, or Daniel Gooch, Gooch's development of this where the semi-cy ...

Ulster
Ulster (; or ; or ''Ulster'') is one of the four traditional or historic provinces of Ireland, Irish provinces. It is made up of nine Counties of Ireland, counties: six of these constitute Northern Ireland (a part of the United Kingdom); the remaining three are in the Republic of Ireland. It is the second-largest (after Munster) and second-most populous (after Leinster) of Ireland's four traditional provinces, with Belfast being its biggest city. Unlike the other provinces, Ulster has a high percentage of Protestantism in Ireland, Protestants, making up almost half of its population. English is the main language and Ulster English the main dialect. A minority also speak Irish, and there are (Irish-speaking regions) in County Donegal which is home to a quarter of the total Gaeltacht population of the Republic of Ireland. There are also large Irish-speaking networks in southern County Londonderry and in the Gaeltacht Quarter, Belfast. Ulster Scots dialect, Ulster-Scots is al ...

Buffer Beam
A headstock of a rail vehicle is a transverse structural member located at the extreme end of the vehicle's underframe. The headstock supports the coupling at that end of the vehicle, and may also support buffers, in which case it may also be known as a buffer beam. The headstocks form part of the underframe of a locomotive or a railroad car. The headstocks of locomotives, railcars and cabcars also support headlamps and the hoses for air brakes, vacuum brakes as well as the cables for train control and head end power. Length over headstocks A commonly used measurement relating to a rail vehicle is its length over headstocks, which is the length of the vehicle excluding its couplings or buffers (if any). Alternative expressions for length over headstocks are length over coupler pulling faces, usually applied to Janney couplers, and length over buffers.
