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.

Lokomotive 85007 22
The Lokomotive (German for "locomotive") is a striking climbing rock north of Kurort Rathen in Saxon Switzerland in Germany. The rock, which resembles a steam locomotive in appearance, is also known as ''Große Ruine'', is about 30 metres high and is divided into two parts: known as ''Lokomotive-Dom'' ("Locomotive Dome") and ''Lokomotive-Esse'' ("Locomotive Chimney"). The ridge between the two is called the ''Kesselgrat'' ("Boiler Ridge"), the rock teeth next to the Esse as ''Pfeife'' ("Whistle"). For a short time there was a weather vane on the dome in the shape of a wheel. The Lokomotive rises on the massif of the ''Honigsteine''. The Dome of the Lokomotive was first climbed in 1886 by Friedrich Hartmann and Robert Kappmeier. In the history of free climbing in Saxon Switzerland the climb of the Esse on 7 June 1903 by Albert Kunze and Oliver Perry-Smith was the first ascent of the Esse and the first step in climbing the open face. Until then climbers had focussed on chimn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electrical Cable
Electricity is the set of physical phenomena associated with the presence and motion of matter possessing an electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. The presence of either a positive or negative electric charge produces an electric field. The motion of electric charges is an electric current and produces a magnetic field. In most applications, Coulomb's law determines the force acting on an electric charge. Electric potential is the Work (physics), work done to move an electric charge from one point to another within an electric field, typically measured in volts. Electricity plays a central role in many modern technologies, serving in electric power where electric current is used to energise equipment, and in electronics dealing w ...

Pilot (locomotive Attachment)
A cowcatcher, also known as a pilot, is the device mounted at the front of a locomotive to deflect obstacles on the track that might otherwise damage or derail it or the train. In the UK, small metal bars called ''life-guards'', ''rail guards'' or ''guard irons'' are provided immediately in front of the wheels. They knock away smaller obstacles lying directly on the running surface of the railhead. Historically, fenced-off railway systems in Europe relied exclusively on those devices and cowcatchers were not required, but in modern systems cowcatchers have generally superseded them. Instead of a cowcatcher, trams use a device called a fender. Objects lying on the tram track come in contact with a sensor bracket, which triggers the lowering of a basket-shaped device to the ground, preventing the overrunning of the obstacles and pushing them along the road surface in front of the wheels. In snowy areas the cowcatcher also has the function of a snowplow. Invention An idea fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Glossary Of Rail Transport Terms
A glossary (from , ''glossa''; language, speech, wording), also known as a vocabulary or clavis, is an alphabetical list of terms in a particular domain of knowledge with the definitions for those terms. Traditionally, a glossary appears at the end of a book and includes terms within that book that are either newly introduced, uncommon, or specialized. While glossaries are most commonly associated with non-fiction books, in some cases, fiction novels sometimes include a glossary for unfamiliar terms. A bilingual glossary is a list of terms in one language defined in a second language or glossed by synonyms (or at least near-synonyms) in another language. In a general sense, a glossary contains explanations of concepts relevant to a certain field of study or action. In this sense, the term is related to the notion of ontology. Automatic methods have been also provided that transform a glossary into an ontology or a computational lexicon. Core glossary A ''core glossary ...

Crashworthiness
Crashworthiness is the ability of a structure to protect its occupants during an impact. This is commonly tested when investigating the safety of aircraft and vehicles. Different criteria are used to figure out how safe a structure is in a crash, depending on the type of impact and the vehicle involved. Crashworthiness may be assessed either prospectively, using computer models (e.g., RADIOSS, LS-DYNA, PAM-CRASH, MSC Dytran, MADYMO) or experiments, or retrospectively, by analyzing crash outcomes. Several criteria are used to assess crashworthiness prospectively, including the deformation patterns of the vehicle structure, the acceleration experienced by the vehicle during an impact, and the probability of injury predicted by human body models. Injury probability is defined using criteria, which are mechanical parameters (e.g., force, acceleration, or deformation) that correlate with injury risk. A common injury criterion is the head impact criterion (HIC). Crashworthiness is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bumper (automobile)
A bumper is a structure attached to or integrated with the front and rear ends of a motor vehicle, to absorb impact in a minor collision, ideally minimizing repair costs. Stiff metal bumpers appeared on automobiles as early as 1904 that had a mainly ornamental function. Numerous developments, improvements in materials and technologies, as well as greater focus on functionality for protecting vehicle components and improving safety have changed bumpers over the years. Bumpers ideally minimize height mismatches between vehicles and Pedestrian safety through vehicle design, protect pedestrians from injury. Regulatory measures have been enacted to reduce vehicle repair costs and, more recently, impact on pedestrians. History Bumpers were, at first, just rigid metal bars. George Albert Lyon invented the earliest car bumper. The first bumper appeared on a vehicle in 1897, and Nesselsdorfer Wagenbau-Fabriksgesellschaft, an Austrian carmaker, installed it. The construction of these bum ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Buff Strength
Buff strength is a design term used in the certification of rail rolling stock. It refers to the required resistance to deformation or permanent damage due to loads applied at the car's ends, such as in a collision. Particular emphasis on buff strength is placed in the United States, with buff strength requirements there being higher than in Europe. United States Buff strength requirements grew out of best-practice design standards during the latter part of the nineteenth century. By the twentieth century, a design limit of was required by federal approval agencies. This was upped to for certain categories in 1945. Federal requirements for buff strength were set in 1999 at for all passenger-carrying units, unless reduced by waivers or special order. The Federal Static and Strength Regulation (49 Code of Federal Regulations § 238.203) requires that a passenger rail car be able to support a longitudinal static compressive load of without permanent deformation. There are other ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Janney Coupler
Knuckle couplers are a semi-automatic form of railway coupling that allow rail cars and locomotives to be securely linked together without rail workers having to get between the vehicles. Originally known as Janney couplers (the original patent name) they are almost always referred to as Knuckles in the US and Canada (regardless of their actual official model name, nowadays generally various AAR types in North America), but are also known as American, AAR, APT, ARA, MCB, Buckeye, tightlock (in the UK) or Centre Buffer Couplers. There are many variations of knuckle coupler in use today, and even more from the past, some variants of knuckle couplers include: Janney: the American original, a rather finicky coupler; reportedly annoying to make open and close. This design was obsolete by 1900. MCB: In the latter 1880's the Master Car Builder's Association (MCB) were faced with choosing a standard from the multitude of mutually incompatible automatic coupler designs then on offer. The ...

Railway Coupling
A coupling or coupler is a mechanism, typically located at each end of a rolling stock, rail vehicle, that connects them together to form a train. The equipment that connects the couplers to the vehicles is the draft gear or draw gear, which must absorb the stresses of the coupling and the acceleration of the train. Throughout the history of rail vehicles, a variety of coupler designs and types have been developed worldwide. Key design considerations include strength, reliability, easy and efficient handling, and operator safety. Automatic couplers engage automatically when the cars are pushed together. Modern versions not only provide a mechanical connection, but can also couple brake lines and data lines. Different countries use different types of couplers. While North American railroads and China use Janney couplers, railroads in the former Soviet Union use SA3 couplers and the European countries use Scharfenberg coupler, Scharfenberg and Buffers and chain coupler, screw ...

Head End Power
In rail transport, head-end power (HEP), also known as electric train supply (ETS), is the electrical power distribution system on a passenger train. The power source, usually a locomotive (or a generator car) at the front or 'head' of a train, provides the electricity used for heating, lighting, electrical and other 'hotel' needs. The maritime equivalent is hotel electric power. A successful attempt by the London, Brighton and South Coast Railway in October 1881 to light the passenger cars on the London to Brighton route heralded the beginning of using electricity to light trains in the world. History Oil lamps were introduced in 1842 to light trains. Economics drove the Lancashire and Yorkshire Railway to replace oil with coal gas lighting in 1870, but a gas cylinder explosion on the train led them to abandon the experiment. Oil-gas lighting was introduced in late 1870. Electrical lighting was introduced in October 1881 by using twelve Joseph Swan, Swan carbon filament incande ...
