2-12-0
Under the Whyte notation for the classification of steam locomotives, 2-12-0 represents the wheel arrangement of two leading wheels on one axle (usually in a leading truck), twelve powered and coupled driving wheels on six axles, and no trailing wheels. Equivalent classifications Other equivalent classifications are: *UIC classification: 1F (also known as German classification and Italian classification) *French classification: 160 * Turkish classification: 67 * Swiss classification: 6/7 Germany While standard German freight train steam locomotives were 2-10-0 types, between 1917 and 1924 the Esslingen locomotive works produced 44 units of the so-called Class K for the Royal Württemberg State Railways (later renumbered to class 59 by the Deutsche Reichsbahn). With a top speed of only 60 km/h these locomotives were designed for heavy duty in mountainous areas such as the Geislinger Steige, with special attention on low load per axle (16 t). During World War II, after electr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Whyte Notation
The Whyte notation is a classification method for steam locomotives, and some internal combustion locomotives and electric locomotives, by wheel arrangement. It was devised by Frederick Methvan Whyte, and came into use in the early twentieth century following a December 1900 editorial in ''American Engineer and Railroad Journal''. The notation was adopted and remains in use in North America and the United Kingdom to describe the wheel arrangements of steam locomotives, but for modern locomotives, multiple units and trams it has been supplanted by the UIC system in Europe and by the AAR system (essentially a simplification of the UIC system) in North America. However, geared steam locomotives do not use the notation. They are classified by their model and their number of trucks. Structure of the system Basic form The notation in its basic form counts the number of leading wheels, then the number of driving wheels, and finally the number of trailing wheels, numbers ...

Württemberg K
The Württemberg Class K steam locomotives of the Royal Württemberg State Railways (''Königlich Württembergische Staats-Eisenbahnen'') were the only twelve-coupled locomotives built for a German railway company. History The 44 engines of this class built by the Maschinenfabrik Esslingen between 1917 and 1924 were intended for work on the Geislingen ramp ('' Geislinger Steige'') and the Baden Black Forest line. As a result of good experiences in Austria and the fact that there was a maximum axle load of only 16 tonnes on those routes, it was decided to produce a twelve-coupled locomotive. The first and last coupled axles were given side-play ( Gölsdorf system), the wheel flanges of the two centre axles were reduced by about 15 mm. The locomotives proved to be a successful design that was very reliable and powerful. In operations on the hilly routes it was very thrifty, however it was not so economical on the flat. The Deutsche Reichsbahn, that had taken over all ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 classifi ...

André Chapelon
André Chapelon (26 October 1892 – 22 July 1978) was a French mechanical engineer and designer of advanced steam locomotives. A graduate engineer of Ecole Centrale Paris, he was one of very few locomotive designers who brought a rigorous scientific method to their design, and he sought to apply up-to-date theories and knowledge in subjects such as thermodynamics, and gas and fluid flow. Chapelon's work was an early example of what would later be called modern steam, and influenced the work of many later designers of those locomotives, such as Livio Dante Porta. Life and career André Xavier Chapelon was born in Saint-Paul-en-Cornillon, Loire, France on 26 October 1892. According to family relatives, his great-grandfather James Jackson immigrated to France from England in 1812, one of many who came to France in the 19th century to teach steel production methods. He achieved a distinction in mathematics and science, and served as an artillery officer during World War I before ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Austrian State Railway
The Imperial-Royal State Railways () abbr. ''kkStB'') or Imperial-Royal Austrian State Railways (''k.k. österreichische Staatsbahnen'',The name incorporating "Austrian" appears, for example, in the 1907 official state handbook (''Staatshandbuch'') and on the title page of the Imperial-Royal Railway Ministry publication''Die neuen österr(eichischen) Alpenbahnen'' Maass’ Söhne, Vienna, 1908.) was the state railway organisation in the Cisleithanian (Austrian) part of the Austro-Hungarian Monarchy. History The introduction of railway traffic in the Austrian Empire had been pushed by pioneers like physicist Franz Josef Gerstner (1756–1832), who advocated a railway connection from the Vltava basin across the Bohemian Massif to the Danube river. After in 1810 a first long horse-drawn railway line was built at the Eisenerz mine in Styria for the transport of iron stones, in 1832 a wagonway between Austrian Linz and České Budějovice (Budweis) in Bohemia opened. It was long and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
German Reich
German ''Reich'' (, from ) was the constitutional name for the German nation state that existed from 1871 to 1945. The ''Reich'' became understood as deriving its authority and sovereignty entirely from a continuing unitary German ''Volk'' ("national people"), with that authority and sovereignty being exercised at any one time over a unitary German "state territory" with variable boundaries and extent. Although commonly translated as "German Empire", the word ''Reich'' here better translates as "realm" or territorial "reach", in that the term does not in itself have monarchical connotations. The name "German ''Reich''" was officially Proclamation of the German Empire, proclaimed on 18 January 1871 at the Palace of Versailles by Otto von Bismarck and William I, German Emperor, Wilhelm I of Prussia. After the Anschluss, annexation of Austria to Germany on 12–13 March 1938, the name "Greater German ''Reich''" () began to be used along with the official name "German ''Reich''". Ac ...

Austria
Austria, formally the Republic of Austria, is a landlocked country in Central Europe, lying in the Eastern Alps. It is a federation of nine Federal states of Austria, states, of which the capital Vienna is the List of largest cities in Austria, most populous city and state. Austria is bordered by Germany to the northwest, the Czech Republic to the north, Slovakia to the northeast, Hungary to the east, Slovenia and Italy to the south, and Switzerland and Liechtenstein to the west. The country occupies an area of and has Austrians, a population of around 9 million. The area of today's Austria has been inhabited since at least the Paleolithic, Paleolithic period. Around 400 BC, it was inhabited by the Celts and then annexed by the Roman Empire, Romans in the late 1st century BC. Christianization in the region began in the 4th and 5th centuries, during the late Western Roman Empire, Roman period, followed by the arrival of numerous Germanic tribes during the Migration Period.

Railway Electrification
Railway electrification is the use of electric power for the propulsion of rail transport. Electric railways use either electric locomotives (hauling passengers or Rail freight transport, freight in separate cars), electric multiple units (Passenger car (rail), passenger cars with their own motors) or both. Electricity is typically generated in large and relatively efficient electric power station, generating stations, transmitted to the railway network and distributed to the trains. Some electric railways have their own dedicated generating stations and electric transmission line, transmission lines, but most purchase power from an electric utility. The railway usually provides its own distribution lines, switches, and transformers. Power is supplied to moving trains with a (nearly) continuous electrical conductor, conductor running along the track that usually takes one of two forms: an overhead line, suspended from poles or towers along the track or from structure or tunnel cei ...

Geislinger Steige
The Geislinger Steige ("Geislingen climb") is an old trade route over the low mountain range of the Swabian Jura in southern Germany. It links Geislingen an der Steige with Amstetten and is one of the most famous ascents in the Jura. The name "Geislinger Steige" refers both to: * The long-distance road between Geislingen an der Steige and Amstetten that has existed since Roman times and, today, is part of the B 10 road. * The railway ramp forming part of the '' Filstalbahn'', a section of the main line between Munich and Stuttgart The ramp is 5.6 km long and climbs a height of 112 m. It has an incline of 1:44.5, which is 22.5 ‰ or 2.25%. The curve radius in places is less than 300 m, with a minimum of 278 m. This section of the line is therefore built in accordance with the standards for mountain railways.Geschichtsverein Geislingen, S. 89 Planning and Construction With the passing of the ''law affecting the construction of railways'' in 1843, the dec ...
