Hancock Air Whistle
The Hancock air whistle was a railroad whistle intended for use on North American diesel locomotives in place of the standard air horn. History Steam era Hancock was a familiar name to railroads during the days of steam. The company produced many appliances, one of which was the popular long-bell three-chime steam whistle. When railroads began dieselising, Hancock, along with other manufacturers of railroad equipment, adjusted their offerings in order to remain competitive. And so Hancock modified their whistle design so they could be used on diesel locomotives. Diesel era Hancock already had vast experience with steam whistles, and practically none with air horns. Also, diesel locomotives were an emerging technology, and most early models were equipped with single-note 'honkers'. These horns were anything but appealing to the general public. Therefore, Hancock developed their line of air whistles in an attempt to romanticize the diesel locomotives. Production of these ai ...

EMD FL9
The EMD FL9 (New Haven Class EDER-5) is a model of electro-diesel locomotive, capable of operating either as a traditional diesel-electric locomotive or as an electric locomotive powered from a third rail. Sixty units were built between October 1956 and November 1960 by General Motors Electro-Motive Division for the New York, New Haven and Hartford Railroad (the "New Haven"). Design Due to concerns about diesel emissions in the East River Tunnels and the underground tracks of Grand Central Terminal and Penn Station, passenger trains entering New York City have long been required to use electrical power, as diesel exhaust would pose a hazard to human health in the confined underground spaces. At the same time, much of the New Haven's trackage was not electrified beyond New Haven. To allow passenger trains to travel to New York City from non-electrified lines without requiring a change of locomotives, the New Haven Railroad purchased a class of locomotive that could switch between d ...

Safety Equipment
Personal protective equipment (PPE) is protective clothing, helmets, goggles, or other garments or equipment designed to protect the wearer's body from injury or infection. The hazards addressed by protective equipment include physical, electrical, heat, chemicals, biohazards, and airborne particulate matter. Protective equipment may be worn for job-related occupational safety and health purposes, as well as for sports and other recreational activities. ''Protective clothing'' is applied to traditional categories of clothing, and ''protective gear'' applies to items such as pads, guards, shields, or masks, and others. PPE suits can be similar in appearance to a cleanroom suit. The purpose of personal protective equipment is to reduce employee exposure to hazards when engineering controls and administrative controls are not feasible or effective to reduce these risks to acceptable levels. PPE is needed when there are hazards present. PPE has the serious limitation that it does ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Railway Safety
Rail transport (also known as train transport) is a means of transport that transfers passengers and goods on wheeled vehicles running on rails, which are incorporated in tracks. In contrast to road transport, where the vehicles run on a prepared flat surface, rail vehicles (rolling stock) are directionally guided by the tracks on which they run. Tracks usually consist of steel rails, installed on sleepers (ties) set in ballast, on which the rolling stock, usually fitted with metal wheels, moves. Other variations are also possible, such as "slab track", in which the rails are fastened to a concrete foundation resting on a prepared subsurface. Rolling stock in a rail transport system generally encounters lower frictional resistance than rubber-tyred road vehicles, so passenger and freight cars (carriages and wagons) can be coupled into longer trains. The operation is carried out by a railway company, providing transport between train stations or freight customer facilit ...

Locomotive Parts
A locomotive or engine is a rail transport vehicle that provides the motive power for a train. If a locomotive is capable of carrying a payload, it is usually rather referred to as a multiple unit, motor coach, railcar or power car; the use of these self-propelled vehicles is increasingly common for passenger trains, but rare for freight (see CargoSprinter). Traditionally, locomotives pulled trains from the front. However, push-pull operation has become common, where the train may have a locomotive (or locomotives) at the front, at the rear, or at each end. Most recently railroads have begun adopting DPU or distributed power. The front may have one or two locomotives followed by a mid-train locomotive that is controlled remotely from the lead unit. __TOC__ Etymology The word ''locomotive'' originates from the Latin 'from a place', ablative of 'place', and the Medieval Latin 'causing motion', and is a shortened form of the term ''locomotive engine'', which was first ...

Steam Whistle
A steam whistle is a device used to produce sound in the form of a whistle using live steam, which creates, projects, and amplifies its sound by acting as a vibrating system (compare to train horn). Operation The whistle consists of the following main parts, as seen on the drawing: the whistle bell (1), the steam orifice or aperture (2), and the valve (9). When the lever (10) is actuated (usually via a pull cord), the valve opens and lets the steam escape through the orifice. The steam will alternately compress and rarefy in the bell, creating the sound. The pitch, or tone, is dependent on the length of the bell; and also how far the operator has opened the valve. Some locomotive engineers invented their own distinctive style of whistling. Uses of steam whistles Steam whistles were often used in factories, and similar places to signal the start or end of a shift, etc. steam-powered railway locomotives, traction engines, and steam ships have traditionally been fitted wi ...

New York, New Haven And Hartford Railroad
The New York, New Haven and Hartford Railroad , commonly known as The Consolidated, or simply as the New Haven, was a railroad that operated in the New England region of the United States from 1872 to December 31, 1968. Founded by the merger of the New York and New Haven Railroad, New York and New Haven and Hartford and New Haven Railroad, Hartford and New Haven railroads, the company had near-total dominance of railroad traffic in Southern New England for the first half of the 20th century. Beginning in the 1890s and accelerating in 1903, New York banker J. P. Morgan sought to monopolize New England transportation by arranging the NH's acquisition of 50 companies, including other railroads and steamship lines, and building a network of electrified trolley lines that provided interurban transportation for all of southern New England. By 1912, the New Haven operated more than of track, with 120,000 employees, and practically monopolized traffic in a wide swath from Boston to New ...

Train Whistle
A train whistle or air whistle (originally referred to as a steam trumpet) is an audible signaling device on a steam locomotive, used to warn that the train is approaching, and to communicate with rail workers. Modern diesel and electric locomotives primarily use a powerful air horn instead of a whistle as an audible warning device. However, the word ''whistle'' continues to be used by railroaders in referring to such signaling practices as "whistling off" (sounding the horn when a train gets underway). The need for a whistle on a locomotive exists because trains move on fixed rails and thus are uniquely susceptible to collision. This susceptibility is exacerbated by a train's enormous weight and inertia, which make it difficult to quickly stop when encountering an obstacle. Hence a means of warning others of the approach of a train from a distance is necessary. As train whistles are inexpensive compared to other warning devices, the use of loud and distinct whistles became the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Romanticism
Romanticism (also known as the Romantic movement or Romantic era) was an artistic, literary, musical, and intellectual movement that originated in Europe towards the end of the 18th century, and in most areas was at its peak in the approximate period from 1800 to 1850. Romanticism was characterized by its emphasis on emotion and individualism, clandestine literature, paganism, idealization of nature, suspicion of science and industrialization, and glorification of the past with a strong preference for the medieval rather than the classical. It was partly a reaction to the Industrial Revolution, the social and political norms of the Age of Enlightenment, and the scientific rationalization of nature. It was embodied most strongly in the visual arts, music, and literature, but had a major impact on historiography, education, chess, social sciences, and the natural sciences. It had a significant and complex effect on politics, with romantic thinkers influencing conservatism, libe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dieselisation
Dieselisation (US: dieselization) is the process of equipping vehicles with a diesel engine or diesel engines. It can involve replacing an internal combustion engine powered by petrol (gasoline) fuel with an engine powered by diesel fuel, as occurred on a large scale with trucks, buses, farm tractors, and building construction machinery after the Second World War. Alternatively it can involve replacing the entire plant or vehicle with one that is diesel-powered; the term commonly describes the generational replacement between the 1930s and the 1970s of railway steam locomotives with diesel locomotives, and associated facilities. Water transport The Two-stroke diesel engine for marine applications was introduced in 1908 and remains in use today. It is the most efficient prime mover to date, models such as the Wärtsilä-Sulzer RTA96-C offer a thermal efficiency of 50% and over 100,000 horsepowers. First steps towards conversions using diesel engines as means of propulsion (on sm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
