Glen Massey Line
The Glen Massey Line was a private railway of 10.6 km near Ngāruawāhia in the Waikato region of New Zealand, built to serve coal mines, and, from 1935, run by the New Zealand Railways Department. The line had grades of 1 in 40, sharp curves - sharpest and 40 of less than - and 22 bridges, including a 91.5-metre-long and 18.3-metre-high timber trestle bridge over Firewood Creek halfway between Ngāruawāhia and Glen Massey and a bridge, adapted in 1917 to take sheep, on piles over the Waipā River, as well as the railway, after collapse of the road bridge. Origins of the railway Glen Massey's coal was known of by 1867, when it was suggested a tramway should be built down what is now known as the Firewood Creek valley. In 1908 government was asked to extend the proposed railway to Whaingaroa Harbour, but rejected that in favour of an extension of the proposed Glen Afton branch. Neither ever happened. Waipa Railway and Collieries Ltd was formed with a nominal capi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clerestory
In architecture, a clerestory ( ; , also clearstory, clearstorey, or overstorey) is a high section of wall that contains windows above eye level. Its purpose is to admit light, fresh air, or both. Historically, ''clerestory'' denoted an upper level of a Roman basilica or of the nave of a Romanesque or Gothic church, the walls of which rise above the rooflines of the lower aisles and are pierced with windows. Similar structures have been used in transportation vehicles to provide additional lighting, ventilation, or headroom. History Ancient world The technology of the clerestory appears to originate in the temples of ancient Egypt. The term "clerestory" is applicable to Egyptian temples, where the lighting of the hall of columns was obtained over the stone roofs of the adjoining aisles, through gaps left in the vertical slabs of stone. Clerestory appeared in Egypt at least as early as the Amarna period. In the Minoan palaces of Crete such as Knossos, by contrast, lightwel ...

2-6-4
Under the Whyte notation for the classification of steam locomotives, a locomotive has two leading wheels, six coupled driving wheels and four trailing wheels. This arrangement is commonly called Adriatic. Overview With only a few known exceptions, the Adriatic wheel arrangement was usually used on tank locomotives, for which various suffixes to indicate the type of tank would be added to the wheel arrangement, for example for an engine with side-tanks. Tender locomotives The earliest known example was the South African Class 6Z, designed by Cape Government Railways (CGR) Chief Locomotive Superintendent Hazlitt Beatty in 1901. The first engines of the class were modified 2-6-2 Prairie locomotives which were equipped with two-axle trailing bogies. In 1902, more were placed in service, but built with the wheel arrangement. The latter were the first known tender locomotives in the world to be built with this wheel arrangement.Neilson, Reid works list, compiled by Austrian loc ...

Baldwin Locomotive Works
The Baldwin Locomotive Works (BLW) was an American manufacturer of railroad locomotives from 1825 to 1951. Originally located in Philadelphia, it moved to nearby Eddystone, Pennsylvania, in the early 20th century. The company was for decades the world's largest producer of steam locomotives, but struggled to compete as demand switched to diesel locomotives. Baldwin produced the last of its 70,000-plus locomotives in 1951, before merging with the Lima-Hamilton Corporation on September 11, 1951, to form the Baldwin-Lima-Hamilton Corporation. The company has no relation to the E.M. Baldwin and Sons of New South Wales, Australia, a builder of small diesel locomotives for sugar cane railroads. History: 19th century Beginning The Baldwin Locomotive Works had a humble beginning. Matthias W. Baldwin, the founder, was a jeweler and whitesmith, who, in 1825, formed a partnership with machinist David H. Mason, and engaged in the manufacture of bookbinders' tools and cylinders for cal ...

Manning Wardle
Manning Wardle was a steam locomotive manufacturer based in Hunslet, Leeds, West Yorkshire, England. Precursor companies The city of Leeds was one of the earliest centres of locomotive building; Matthew Murray built the first commercially successful steam locomotive, ''Salamanca'', in Holbeck, Leeds, in 1812. By 1856, a number of manufacturers had sprung up in the city, including Kitson and Company, and E. B. Wilson and Company, later The Railway Foundry after 1848. Manning Wardle The Railway Foundry (E.B Wilson from 1838-48) operated in Leeds until 1858. At least some of the company's designs and some materials were purchased by Manning Wardle & Company, who located their Boyne Engine Works in Jack Lane in the Hunslet district of the city. Steam locomotive construction commenced on the site in 1859. Within the next few years, two other companies, the Hunslet Engine Company and Hudswell, Clarke & Company also opened premises in Jack Lane. There was a good deal of st ...

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] |
0-6-2
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 two trailing wheels on one axle. The type is sometimes known as a Webb or a Branchliner. Overview While some locomotives with this wheel arrangement had tenders, the majority were tank locomotives which carried their coal and water onboard. Usage Finland Finland used two classes of 0-6-2T locomotive, the Vr2 and the Vr5. The Vr2 class was numbered in the range from 950 to 965. Five of them are preserved in Finland, no. 950 at Joensuu, no. 951 at Tuuri, no. 953 at Haapamäki, no. 961 at Jyväskylä and no. 964 at the Veturimuseo at Toijala. The Vr5 class was numbered in the range from 1400 to 1423. No. 1422 is preserved at Haapamäki. Philippines There were 30 ''Dagupan''-type locomotives built between 1889 and 1890. All were tank locomotives, weighed and were run a maximum speed of . These ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nationalization
Nationalization (nationalisation in British English) is the process of transforming privately-owned assets into public assets by bringing them under the public ownership of a national government or state. Nationalization usually refers to private assets or to assets owned by lower levels of government (such as municipalities) being transferred to the state. Nationalization contrasts with privatization and with demutualization. When previously nationalized assets are privatized and subsequently returned to public ownership at a later stage, they are said to have undergone renationalization. Industries often subject to nationalization include the commanding heights of the economy – telecommunications, electric power, fossil fuels, railways, airlines, iron ore, media, postal services, banks, and water – though, in many jurisdictions, many such entities have no history of private ownership. Nationalization may occur with or without financial compensation to the former owners. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
4-8-0
Under the Whyte notation for the classification of steam locomotives, represents the wheel arrangement of four leading wheels on two axles, usually in a leading truck or bogie, eight powered and coupled driving wheels on four axles and no trailing wheels. In North America and in some other countries the type was usually known as the Twelve-wheeler. Overview The first locomotive is believed to have been the ''Centipede'', a tender locomotive built by Ross Winans in 1855 for the Baltimore and Ohio Railroad in the United States of America, where it remained in service for nearly twenty years. It appears to have been delivered in a cab-forward type of configuration that was modified to a Camel configuration in 1864.Carling, D. Rock (1972). ''4-8-0 Tender Locomotives''. Drake Publishers Inc. On a Camel locomotive the cab was mounted atop the boiler, unlike the later Camelback locomotive whose cab straddled the boiler and that first appeared around 1877.

4-6-4
Under the Whyte notation for the classification of locomotives, represents the wheel arrangement of four leading wheels, six powered and coupled driving wheels and four trailing wheels. In France where the type was first used, it is known as the Baltic while it became known as the Hudson in most of North America. Overview Tender locomotives The 4-6-4 tender locomotive was first introduced in 1911 and throughout the 1920s to 1940s, the wheel arrangement was widely used in North America and to a lesser extent in the rest of the world. The type combined the basic design principles of the 4-6-2 type with an improved boiler and larger firebox that necessitated additional support at the rear of the locomotive. In general, the available tractive effort differed little from that of the 4-6-2, but the steam-raising ability was increased, giving more power at speed. The 4-6-4 was best suited to high-speed running across flat terrain. Since the type had fewer driving wheels than carryin ...
