Cab (locomotive)
The cab, crew compartment or driver's compartment of a locomotive, or a self-propelled rail vehicle, is the part housing the train driver, fireman or secondman (if any), and the controls necessary for the locomotive or self-propelled rail vehicle's operation. Cab locations On steam locomotives, the cab is normally located to the rear of the firebox, although steam locomotives have sometimes been constructed in a cab forward or camelback configuration. The cab, or crew or driver's compartment of a diesel or electric locomotive will usually be found either inside a cabin attached to a hood unit or cowl unit locomotive, or forming one of the structural elements of a cab unit locomotive. The former arrangement is now the norm in North America for all types of diesel or electric locomotives. In Europe, most modern locomotives are cab units with two cabs, one at each end. However, the locomotives powering some high speed European trains are normally cab units with one cab, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cab Unit
In North American railroad terminology, a cab unit is a railroad "locomotive" with its own cab and controls. "Carbody unit" is a related term, which may be either a cabless booster unit controlled from a linked cab unit, or a cab unit that contains its own controls. Characteristics With both body styles, a bridge-truss design framework is used to make the body a structural element of the locomotive. The body extends the full width and length of the locomotive. The service walkways are inside the body. Carbody units, gaining rigidity from the body trusswork, require less structural weight to achieve rigidity than do locomotives with non-structural bodies. For that reason, carbody construction was favored to increase the power-to-weight ratio for early diesel locomotives, before the power available with diesel technology was increased. Recent years have seen carbody construction revived in the quest for greater fuel efficiency with passenger locomotives. The full-width body ...

Sicherheitsfahrschaltung
Sifa is a type of deadman's control system used on German-influenced European railways.{{cite web , url = http://www.virtualmarket.innotrans.de/index.php5?id=1022238&highlight=&fid=523&offset=0&Action=showProduct , title = Deadman's control system UDB , accessdate=2008-12-24 Although deadman's pedals are commonly used on railways worldwide, Sifa systems are specifically those codified by German Industrial Norms VDE 0119-207-5. In Switzerland the equivalent system is called 'safety control' (''Sicherheitssteuerung'').Eidgenössisches Departement für Umwelt, Verkehr, Energie und Kommunikation''Ausführungsbestimmungen zur Eisenbahnverordnung (AB-EBV)', as at: 01July 2016 Description Sifa is short for ''Sicherheitsfahrschaltung'', German for "safety driving circuit". It is usually a pedal and/or large press button, which monitors the alertness of the driver. The driver has to repeatedly press a button after a fixed interval; if they fail to do so, the train will carry out a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Standard Electric Locomotive
{{Unreferenced, date=June 2019, bot=noref (GreenC bot) Einheits-Elektrolokomotive (translates as standard electric locomotive) is a German railroad term for the Class E10, Class E40, Class E41 and Class E50 locomotives that were commissioned after World War II by the Deutsche Bundesbahn of West Germany. The goal of the ''Einheits-Elektrolokomotive'' was to present a common platform on which the engines were based to simplify maintenance and provide interchangeability of parts. This had been done before by the ''Einheitsdampflokomotiven'' or 'standard steam locomotives' of the Deutsche Reichsbahn during the 1920s. The DB classes greatly exceeded their estimated lifetime of 30 years, many engines of the class E10 still are in service today, even though they are being actively phased out in favour of newer engines by Deutsche Bahn AG, the successor of the Deutsche Bundesbahn. For further description of the program see also the article on DB Class E 40. See also * History of rail ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rheumatism
Rheumatism or rheumatic disorders are conditions causing chronic, often intermittent pain affecting the joints or connective tissue. Rheumatism does not designate any specific disorder, but covers at least 200 different conditions, including arthritis and "non-articular rheumatism", also known as "regional pain syndrome" or "soft tissue rheumatism". There is a close overlap between the term soft tissue disorder and rheumatism. Sometimes the term "soft tissue rheumatic disorders" is used to describe these conditions. The term "Rheumatic Diseases" is used in MeSH to refer to connective tissue disorders. The branch of medicine devoted to the diagnosis and therapy of rheumatism is called rheumatology. Types Many rheumatic disorders of chronic, intermittent pain (including joint pain, neck pain or back pain) have historically been caused by infectious diseases. Their etiology was unknown until the 20th century and not treatable. Postinfectious arthritis, also known as reactive art ...

Max Maria Von Weber
Max Maria von Weber (25 April 1822 in Dresden – 18 April 1881 in Berlin) was a German civil engineer who contributed to the development of railways in Austria and Germany. He was born in Dresden in the Kingdom of Saxony, the son of the composer Carl Maria von Weber, and received his early training in the Dresden schools. Part of his experience was gained under Isambard Kingdom Brunel and George Stephenson in England. In 1850, he entered the civil service of his native kingdom. In 1870 he went to Vienna, where he did much toward the extension of Austrian railways. In 1878 he was called in a similar capacity to Berlin Berlin ( , ) is the capital and largest city of Germany by both area and population. Its 3.7 million inhabitants make it the European Union's most populous city, according to population within city limits. One of Germany's sixteen constitue ....

John Bull (locomotive)
''John Bull'' is a historic British-built railroad steam locomotive that operated in the United States. It was operated for the first time on September 15, 1831, and became the oldest operable steam locomotive in the world when the Smithsonian Institution ran it under its own steam in 1981.Klein and Bell, pp 280–1. Built by Robert Stephenson and Company, it was initially purchased by and operated for the Camden and Amboy Railroad, the first railroad in New Jersey, which gave it the number 1 and its first name, "''Stevens''". (Robert L. Stevens was president of the Camden and Amboy Railroad at the time.) The C&A used it heavily from 1833 until 1866, when it was removed from active service and placed in storage. After the C&A's assets were acquired by the Pennsylvania Railroad (PRR) in 1871, the PRR refurbished and operated the locomotive a few times for public displays: it was fired up for the Centennial Exposition in 1876 and again for the National Railway Appliance Exhibit ...

Crampton Locomotive
A Crampton locomotive is a type of steam locomotive designed by Thomas Russell Crampton and built by various firms from 1846. The main British builders were Tulk and Ley and Robert Stephenson and Company. Notable features were a low boiler and large driving wheels. The crux of the Crampton patent was that the single driving axle was placed behind the firebox, so that the driving wheels could be very large. This helped to give this design a low centre of gravity, so that it did not require a very broad-gauge track to travel safely at high speeds. Its wheel arrangement was usually or . Design variations Because the single driving axle was behind the firebox, Crampton locomotives usually had outside cylinders. However, some inside cylinder versions were built using indirect drive, then known as a ''jackshaft''. The inside cylinders drove a crankshaft located in front of the firebox and the crankshaft was connected to the driving wheels by outside rods. Some long-wheelbase s we ...

Footplate
A footplate provides the structure on which a locomotive driver and fireman stand in the cab to operate a British or continental European steam locomotive. It comprises a large metal plate that rests on top of the locomotive frame, usually it is covered with wooden floorboards. It takes up the full width of the locomotive cab, and in depth it extends from the front of the cab to the coal bunker on the tender. The cab and other superstructure elements are in turn mounted on it. On some locomotives, the footplate is extended beyond the front of the cab to form a walkway around the boiler – usually referred to as the "running board" or "foot board" – to facilitate inspection and maintenance. In Britain, the word remains in use as a synonym for the cab or working in the cab, even in the context of diesel and electric locomotives, as in the expression of working ''on the footplate''. The term can also be applied to the external step along the side of a classical tram. Nation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stephenson's Rocket
Stephenson's ''Rocket'' is an early steam locomotive of 0-2-2 wheel arrangement. It was built for and won the Rainhill Trials of the Liverpool and Manchester Railway (L&MR), held in October 1829 to show that improved locomotives would be more efficient than stationary steam engines. ''Rocket'' was designed and built by Robert Stephenson in 1829, and built at the Forth Street Works of his company in Newcastle upon Tyne. Though ''Rocket'' was by no means the first steam locomotive, it was the first to bring together several innovations to produce the most advanced locomotive of its day. It is the most famous example of an evolving design of locomotives by Stephenson that became the template for most steam engines in the following 150 years. The locomotive was preserved and displayed in the Science Museum in London until 2018, after which it was displayed at the National Railway Museum in York. Design Overall layout The locomotive had a tall smokestack chimney at the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cowl Unit
A cowl unit is a body style of diesel locomotive. The terminology is a North American one, though similar locomotives exist elsewhere. A cowl unit is one with full-width enclosing bodywork, similar to the cab unit style of earlier locomotives, but unlike the cab unit style, the bodywork is merely a casing and is not load-bearing. All the strength is in the locomotive's frame, beneath the floor, rather than the bridge-truss load-bearing carbody of the earlier type. Cowl units were originally produced at the request of the Santa Fe, had a full-width 'cowl' body built on a hood unit frame which provided all the structural strength; the bodywork was cosmetic, rather than a load-bearing bridge truss frame as in cab units. Most cowl units have been passenger-hauling locomotives. In this service, the cowl unit's full width bodywork and sleek sides match the passenger cars, do not allow unwanted riders, and allow the decorative, advertising paintwork desired by passenger operators. ...

Hood Unit
A hood unit, in North American railroad terminology, is a body style for diesel and electric locomotives where the body is less than full-width for most of its length and walkways are on the outside. In contrast, a cab unit has a full-width carbody for the length of the locomotive and walkways inside. A hood unit has sufficient visibility to be operated in both directions from a single cab. Also, the locomotive frame is the main load-bearing member, allowing the hood to be non-structural and easily opened or even removed for maintenance. History The hood unit evolved from the switcher locomotive. A switcher's long hood is normally low enough that the crew can see over it, and there typically is no short hood. Alco introduced the road switcher concept with the RS-1, which was an enlarged switcher with a short hood ahead of the cab. This was added to provide protection for the crew in case of a collision. The low long hood was retained, though its increased length made visibi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
