Headstock (rolling Stock)
A headstock of a Railroad car, rail vehicle is a transverse structural member located at the extreme end of the vehicle's underframe. The headstock supports the railway coupling, coupling at that end of the vehicle, and may also support Buffer (rail transport), 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 Control car (rail), cabcars also support Locomotive headlamp, headlamps and the Hose (tubing), hoses for Railway air brake, air brakes, vacuum brakes as well as the Electrical cable, cables for Push–pull train, 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 Railway coupling, couplings or Buffer (rail transport), buffers (if any). Alternative expressions for length over headstocks are length ove ...

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 chimneys ...

Electrical Cable
An electrical cable is an assembly of one or more wires running side by side or bundled, which is used to carry electric current. One or more electrical cables and their corresponding connectors may be formed into a ''cable assembly'', which is not necessarily suitable for connecting two devices but can be a partial product (e.g. to be soldered onto a printed circuit board with a connector mounted to the housing). Cable assemblies can also take the form of a cable tree or cable harness, used to connect many terminals together. Etymology The original meaning of ''cable'' in the electrical wiring sense was for submarine telegraph cables that were armoured with iron or steel wires. Early attempts to lay submarine cables without armouring failed because they were too easily damaged. The armouring in these early days (mid-19th century) was implemented in separate factories to the factories making the cable cores. These companies were specialists in manufacturing wire rope of ...

Pilot (locomotive)
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 Derailment, 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 dragging them along the road surface in front of the wheels. In snowy areas the cowcatcher also has the function of a Snowplow#Railway sno ...

Glossary Of Rail Transport Terms
Rail terminology is a form of technical terminology. The difference between the American term ''railroad'' and the international term ''railway'' (used by the International Union of Railways and English-speaking countries outside the United States) is the most significant difference in rail terminology. These and other terms have often originated from the parallel development of rail transport systems in different parts of the world. In English-speaking countries outside the United Kingdom, a mixture of US and UK terms may exist. Various global terms are presented here. Where a term has multiple names, this is indicated. The abbreviation "UIC" refers to standard terms adopted by the International Union of Railways in its official publications and thesaurus. 0–9 A B ...

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. Depending on the nature of the impact and the vehicle involved, different criteria are used to determine the crashworthiness of the structure. Crashworthiness may be assessed either prospectively, using computer models (e.g., 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 asse ...

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 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 it was installed by Nesselsdorfer Wagenbau-Fabriksgesellschaft, a Czech carmaker. The construction of these bumpers was not reliable as they featured o ...

Buff Strength
Buff strength is a design term used in the certification of passenger railroad cars. It refers to the required resistance to deformation or permanent damage due to loads applied at the car's ends, either from push-or-pull loads on the Buffer (rail transport), buffer, Janney coupler or when rolling at slow speed into a fixed barrier such as a buffer stop. 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 o ...

Janney Coupler
Janney 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. They are also known as American, AAR, APT, ARA, MCB, knuckle, Buckeye, tightlock (in the UK), Henricot (in Belgium) or Centre Buffer Couplers. Background Janney couplers were first patented in 1873 by Eli H. Janney (). Andrew Jackson Beard was amongst various inventors that made a multitude of improvements to the knuckle coupler; Beard's patents were granted 23 November 1897, which then sold for approximately $50,000, and granted 16 May 1899. In the UK, several versions of Janney couplers are fitted to a limited number of coaches, multiple units, wagons and locomotives. Janney Type E, Type F Interlock, and Type H tightlock couplings are compatible subtypes, each intended for specific rail car types. Prior to the formation of the Association of American Railroads (AAR) these were known as ...

Railway Coupling
A coupling (or a coupler) is a mechanism typically placed at each end of a railway vehicle that connects them together to form a train. A variety of coupler types have been developed over the course of railway history. Key issues in their design include strength, reliability, ease of making connections and operator safety. The equipment that connects the couplings to the vehicles is the draft gear or draw gear and these must absorb the stresses of coupling and train acceleration. Nomenclature Compatible and similar couplings or couplers are frequently referred to using widely differing make, brand, or regional names, or nicknames, which can make describing standard or typical designs confusing. Dimensions and ratings noted in these articles are usually of nominal or typical components and systems, though standards and practices also vary widely with railway, region, and era. Buffers and chain The basic type of coupling on railways following the British tradition is the bu ...

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 Swan carbon filament incandescent lamps c ...
