GSR Class J15
The GS&WR Class 101, classified as Class 101 or Class J15 by the Great Southern Railways, was a class of 0-6-0 steam locomotives designed for working goods traffic although they did, and were quite capable of, working branch and secondary passenger trains. History The 101s were by far the most numerous class of locomotive (diesel or steam) ever to run in Ireland with 111 being built between 1866 and 1903. The great majority were built by the GS&WR at Inchicore Works, though the construction of some examples was contracted out to Beyer, Peacock & Company (12) and Sharp, Stewart & Company (8). The design is attributed to Alexander McDonnell, although evidence points to him developing the design from drawings supplied from Beyer, Peacock and Company of Manchester, England. McDonell appears to have utilised the drawings and produced a number of ''hybrids'' where parts were salvaged from a number of withdrawn locomotives from various builders; the ''class 101'' Inchicore Works ...

Belpaire Firebox
The Belpaire firebox is a type of firebox used on steam locomotives. It was invented by Alfred Belpaire of Belgium in 1864. Today it generally refers to the shape of the outer shell of the firebox which is approximately flat at the top and square in cross-section, indicated by the longitudinal ridges on the top sides. However, it is the similar square cross-section inner firebox which provides the main advantages of this design i.e. it has a greater surface area at the top of the firebox where the heat is greatest, improving heat transfer and steam production, compared with a round-top shape. The flat firebox top would make supporting it against pressure more difficult (e.g. by means of girders, or stays) compared to a round-top. However, the use of a similarly shaped square outer boiler shell allows simpler perpendicular stays to be used between the shells. The Belpaire outer firebox is, nevertheless, more complicated and expensive to manufacture than a round-top version. Due ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beyer, Peacock And Company
Beyer, Peacock and Company was an English railway locomotive manufacturer with a factory in Openshaw, Manchester. Founded by Charles Beyer, Richard Peacock and Henry Robertson, it traded from 1854 until 1966. The company exported locomotives, and machine tools to service them, throughout the world. Founders German-born Charles Beyer had undertaken engineering training related to cotton milling in Dresden before moving to England in 1831 aged 21. He secured employment as a draughtsman at Sharp, Roberts and Company's Atlas works in central Manchester, which manufactured cotton mill machinery and had just started building locomotives for the Liverpool and Manchester Railway. There he was mentored by head engineer and prolific inventor of cotton mill machinery, Richard Roberts. By the time he resigned 22 years later he was well established as the company's head engineer; he had been involved in producing more than 600 locomotives. Richard Peacock had been chief engineer of the M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steam Passing Drumbane Crossing - Geograph
Steam is a substance containing water in the gas phase, and sometimes also an aerosol of liquid water droplets, or air. This may occur due to evaporation or due to boiling, where heat is applied until water reaches the enthalpy of vaporization. Steam that is saturated or superheated is invisible; however, "steam" often refers to wet steam, the visible mist or aerosol of water droplets formed as water vapor condenses. Water 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 vapor pressure, it can create a steam explosion. Typ ...

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.

Pilot Engine
In railroad terminology, double heading indicates the use of two locomotives at the front of a train, each operated individually by its own crew. The practice of triple-heading involves the use of three locomotives. The practice of multi-heading involves the use of multiple locomotives and so on. Double heading is most common with steam locomotives, but is also practised with diesel locomotives. It is not strictly the same practice as two or more diesel or electric locomotives working ' in multiple' (or 'multiple-working'), where both (or all) locomotives are controlled by a single driver in the cab of the leading locomotive. Advantages Double heading is practised for a number of reasons: * In the UK it was usually to gain traction on steep inclines, twice the amount of driven wheels - twice the amount of grip. * The need for additional motive power when a single locomotive is unable to haul the train due to uphill grades, excessive train weight, or a combination of the two ...

Great Northern Railway (Ireland)
The Great Northern Railway (Ireland) (GNR(I) or GNRI) was an Irish gauge () railway company in Ireland. It was formed in 1876 by a merger of the Irish North Western Railway (INW), Northern Railway of Ireland, and Ulster Railway. The governments of Ireland and Northern Ireland jointly nationalised the company in 1953, and the company was liquidated in 1958: assets were split on national lines between the Ulster Transport Authority and Córas Iompair Éireann. Foundation The Ulster, D&D and D&BJct railways together formed the main line between Dublin and Belfast, with the D&BJct completing the final section in 1852 to join the Ulster at . The GNRI's other main lines were between Derry and and between Omagh and Portadown. The Portadown, Dungannon and Omagh Junction Railway together with the Londonderry and Enniskillen Railway enabled GNRI trains between Derry and Belfast to compete with the Belfast and Northern Counties Railway, and both this and the Dundalk route gave connectio ...

Dublin And Belfast Junction Railway
Dublin and the Belfast Junction Railway (D&BJct, Irish: Iarnród Bhaile Átha Cliath agus Acomhal Bhéal Feirste) was an Irish gauge () railway in Ireland. The company was incorporated in 1845 and opened its line in stages between 1849 and 1853, with the final bridge over the River Boyne opening in 1855. It linked the Ulster Railway (UR) from Belfast to Portadown and Dublin and Drogheda Railway (D&D) from Drogheda to Dublin, completing the missing link in the Belfast–Dublin line. History The Boyne Viaduct at Drogheda was not built until 1854–55, at a cost of £124,000, to the design of Sir John Macneill, who was the consulting engineer for the D&BJct. Route The D&BJct line from Drogheda to Portadown connected the Ulster Railway's – – Belfast original line with the Dublin and Drogheda Railway's Dublin Amiens Street – Drogheda line, forming the main line between Dublin and Belfast. Aftermath In 1875, the D&BJct merged with the Dublin and Drogheda Railway (D&D ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GSR Class 700
The Great Southern Railways (GSR) Class 700 consisted of five 0-6-0 locomotives built by Inchicore railway works in 1929 and were the last locomotives designed by J. R. Bazin. The Class 710 consisted of ten 0-6-0 locomotives built by Inchicore railway works in 1934. History Class 700 The design was more traditional with a saturated Belpaire boiler that was unique to the 700 class. It was also fitted with slide valves as opposed to piston valves. The tenders used initially were those reallocated from withdrawn 360 class 4-6-0. A more modern feature was underslung springs. Operationally the need for the class has subsequently been questioned and speculation has arisen that it was to use up surplus type 60 boilers. This class seems to have compared poorly with the older 101 Class when especially when the latter were fitted with superheated boilers, possibly due to an inadequate heating surface leading to high coal and water consumption. Class 710 They were more modern than ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canal Street Works
Canals or artificial waterways are waterways or engineered channels built for drainage management (e.g. flood control and irrigation) or for conveyancing water transport vehicles (e.g. water taxi). They carry free, calm surface flow under atmospheric pressure, and can be thought of as artificial rivers. In most cases, a canal has a series of dams and locks that create reservoirs of low speed current flow. These reservoirs are referred to as ''slack water levels'', often just called ''levels''. A canal can be called a ''navigation canal'' when it parallels a natural river and shares part of the latter's discharges and drainage basin, and leverages its resources by building dams and locks to increase and lengthen its stretches of slack water levels while staying in its valley. A canal can cut across a drainage divide atop a ridge, generally requiring an external water source above the highest elevation. The best-known example of such a canal is the Panama Canal. Many c ...
