Highland Railway O Class
The Highland Railway O Class locomotives were built as 2-4-0T tank engines, but were soon rebuilt as 4-4-0Ts. They were designed by David Jones for Scottish Railway companies and three were built at the company's Lochgorm Works in 1878 and 1879. Dimensions They had coupled wheels, outside cylinders and weight (in original condition) of 36 tons. Numbering Rebuilding They were rebuilt as 4-4-0Ts in 1881–82 due to trouble with the single leading axle. Transfer to LMS All three were still in service in 1923, although relegated to shunting duties, and they were transferred to the London, Midland and Scottish Railway (LMS) at the Grouping Grouping may refer to: * Muenchian grouping * Principles of grouping * Railways Act 1921, also known as Grouping Act, a reorganisation of the British railway system * Grouping (firearms), the pattern of multiple shots from a sidearm See also ....

NER Class O
The NER Class O (LNER Class G5) was a class of 0-4-4T steam locomotives of the North Eastern Railway, designed by the company's Chief Engineer, Wilson Worsdell. They all survived into British Railways ownership in 1948 and their BR numbers were 67240-67349. They were withdrawn between 1950 and 1958. Accidents and incidents In July 1957, locomotive No. No. 67338 was used for a series of tests into the performance of concrete sleepers when trains were derailed. These tests took place between Halifax and Keighley, Yorkshire Yorkshire ( ; abbreviated Yorks), formally known as the County of York, is a Historic counties of England, historic county in northern England and by far the largest in the United Kingdom. Because of its large area in comparison with other Eng .... Preservation None of the G5s was preserved, although a new build is in the works at Shildon.

NZR O Class
The NZR O class consisted of six steam locomotives that operated on New Zealand's national rail network. Ordered from the Baldwin Locomotive Works of Pennsylvania in 1885, three arrived in time to begin work in December 1885, while two more were placed in service in January 1886 and the sixth in February 1886. After almost four decades of service, all six were withdrawn in May 1922. None survived to be preserved, although two engine frames and 5 tenders from O class locomotives are known to exist near Summit on the former Rimutaka Incline. The Baldwin and Rogers locomotives reflected the styling adopted in the 1870s by American builders with elements from the Renaissance Revival and Neo Baroque The Baroque Revival, also known as Neo-Baroque (or Second Empire architecture in France and Wilhelminism in Germany), was an architectural style of the late 19th century. The term is used to describe architecture and architectural sculptur ... architectural styles, and with Islami ...

Russian Locomotive Class O
The Russian steam locomotive class O (from russian: Основной) was an early type of Russian steam locomotives. 9,129 locomotives were built between 1890 and 1928; hence it was the second most numerous class of locomotive in Russia, after E class, which was a unique number even on the international level. Variants Basic variants were early Od and OD (Russian: О''д'', OД) with Joy valve gear and most numerous later OV (OВ) with Walschaerts valve gear. Some locomotives were built as two cylinder simple expansion and others as two cylinder compounds. Armoured locomotives During World War I, the Russian Civil War and the Eastern Front of World War II O-class locomotives were widely used as standard armoured locomotives in armoured trains due to rugged construction and low silhouette. Relatively lightweight, these locomotives could carry more armor without overloading the track. Gallery File:Model of Armoured train.JPG, A model of a Soviet Armoured train in the Museum ...

SER O Class
The South Eastern Railway (SER) O Class (some of which were later rebuilt, becoming the O1 Class) was a class of 0-6-0 steam locomotive designed for freight work, and were the main freight engines of the SER, and later the South Eastern and Chatham Railway (SECR) for a number of years. However, they were displaced by the more powerful C class locomotives following the amalgamation of the South Eastern Railway and London, Chatham and Dover Railway (LCDR) in 1899. This relegated the class to working on the numerous branch lines in Kent, on both passenger and freight work. They worked most notably on the Kent & East Sussex Railway and East Kent Railway, operating coal trains from the Kent coal fields to London, as well as shunting work at such locations as Shepherds Well, Hoo Junction and Ashford. The majority were withdrawn before the outbreak of the Second World War in 1939, and those that remained were slowly withdrawn from nationalisation onwards. The death knell for the ...

WAGR O Class
The Western Australian Government Railways (WAGR) O Class was a class consisting of fifty-six 2-8-0 steam locomotives which were introduced by the WAGR between 1896 and 1912. Despite them being tender locomotives, they also featured short boiler side tanks for additional water storage. A useful feature for the long distances required by operation on Western Australia's country lines. History Between 1896 and 1898, the WAGR took delivery of 36 O class locomotives from Neilson & Co with a further 10 built by Dübs & Co. They initially operated services on the Eastern Railway and on the South Western Railway to Collie before being superseded by the Ec and K classes and moving to branch line duties. In 1907/08, 10 O class were rebuilt as N Class suburban tank engines. Between 1909 and 1912, Midland Railway Workshops built a further 10 as the Oa class. The last examples of the O class were withdrawn from service in 1962. O218 has been preserved at the Western Australian Rai ...

O-class Melbourne Tram
The O-class Melbourne tram were a group of four trams built in 1912 by Duncan & Fraser (Adelaide) for the Prahran & Malvern Tramways Trust (P&MTT) upon the recommendation of W. G. T. Goodman, Chief Engineer and General manager of the Trams in Adelaide, Adelaide tramways. They were allocated P&MTT fleet numbers 21 to 24. At the time of their introduction, they were by far the largest street-vehicles in Melbourne, and earned the nicknames ''Zeppelins'' and ''HMS Dreadnought (1906), Dreadnoughts''. Proving to be less than satisfactory in service, they were later sold to the Hawthorn Tramways Trust (HTT) in August 1916 as "surplus to requirements", however P&MTT soon ordered replacement tramcars. Coincidentally they retained their fleet numbers (21 to 24) whilst at Hawthorn. All passed to the Melbourne & Metropolitan Tramways Board (M&MTB) on 2 February 1920, when that body took-over the HTT. Originally known as 'Metropolitan Cars', they were classified as O-class and renumbered 127 to ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

O-class Sydney Tram
The O-class trams were a class of trams operated on the Trams in Sydney, Sydney tram network. History A prototype (806) was built at Randwick Bus Depot, Randwick Tramway Workshops in 1907, before the Meadowbank Manufacturing Company built a further 625 between 1908 and 1914. They were nicknamed ''Dreadnoughts'', after a powerful Dreadnought, British warship of the day, the Sydney press referred to them as ''Toastracks'' as all the seats were transverse or crossbench. Between 1918 and 1946, eleven (855, 935, 943, 1007, 1089, 1170, 1241, 1372, 1383 and 1451) were rebuilt to resemble the Sydney P-Class Tram, P-class trams when heavy body repairs were required and reclassified as the O/P class. The last was withdrawn in 1958. Design The O-class tram has a combination of enclosed and open sections. Ladies would generally sit in the enclosed compartments, while gentlemen sat in the open compartments. In the centre are the four closed sections, accessible to the street via sliding door ...

Stellar Classification
In astronomy, stellar classification is the classification of stars based on their stellar spectrum, spectral characteristics. Electromagnetic radiation from the star is analyzed by splitting it with a Prism (optics), prism or diffraction grating into a spectrum exhibiting the Continuum (spectrum), rainbow of colors interspersed with spectral lines. Each line indicates a particular chemical element or molecule, with the line strength indicating the abundance of that element. The strengths of the different spectral lines vary mainly due to the temperature of the photosphere, although in some cases there are true abundance differences. The ''spectral class'' of a star is a short code primarily summarizing the ionization state, giving an objective measure of the photosphere's temperature. Most stars are currently classified under the Morgan–Keenan (MK) system using the letters ''O'', ''B'', ''A'', ''F'', ''G'', ''K'', and ''M'', a sequence from the hottest (''O'' type) to the coo ...
